This gadget was purchased on August 31, 2012 in one of the DNS stores in the city of Izhevsk on the occasion of an upcoming birthday at a price of 5,390 rubles (by the way, the price at the time of writing the review had dropped to 4,990 rubles), before that I had been looking for a compromise between price and functionality for a long time and decided to take either Air Tab e71 or Air Tab e72. As a result, the scales swung towards the Air Tab e72. In general, I went into the store, went up to the stand with tablets, within 5 minutes after inspection I decided to take the E72 model, despite the completely discharged battery, they checked the device by connecting the power supply, checked the equipment (more on that a little later), filled out the documents, and voila - I'm the new owner of a cool tablet.
The selection criteria were as follows: Android 4 on board, a processor of at least 1 GHz, also 1 gig of RAM, 8 gig of internal memory, and a 7-inch screen with a good resolution of 1024 by 600, all this was available in the branded Internet tablet DNS Air Tab e72, plus a good bonus in the form of GPS. The device comes in a nice cardboard box with basic characteristics and a cool alien.
The package includes a tablet, a mini-USB charger, USB cable for the host, a cable for connecting to the computer, a cloth for the screen and headphones.
Appearance The tablet does not have an elegant design, there is a black bezel around the display, the back cover is silver, but I can’t figure out whether it’s plastic or metal (on the store’s website metal is indicated), although judging by the price, I think it’s plastic, on the front panel there is a peephole for a nominal camera for Skype - 0.3 MP, that's all. On the back cover there are slots for speakers and a DNS brand emblem, a reset hole, and the model name and country of origin - China, of course. TFT display, resolution 1024 by 600, viewing angles are not very good, but there are no complaints, since I understand perfectly well that it is a budget option. I haven’t tested it in the sun, but I think it will make me blind.
At the top end there are microUSB connectors (used for both charging and connecting external devices, which is not good), mini HDMI (only there is no cable ☹), of course, a standard headset jack, a connector for microSD.
WITH right side Tablet rocker - volume control, home button, screen lock button and also a switch.
The device comes with the Android 4.0.3 operating system installed and a minimum set of programs, most importantly Play Market it’s worth it, but what you need - you download via Wi-Fi or others in an accessible way, the native browser was still there, file manager, Mail agent, voice recorder, program for communication "in contact", Yandex maps, navigation from Google. All necessary programs I installed it without problems through the market, I simply threw some of it onto a memory card and installed it through the file manager. All programs work correctly, without brakes, movies are a blast, books are read using Cool Reader, I don’t really play games, but I installed a few for testing, I think gamers will be quite happy with this option. The device is equipped with a GPS module, it picks up satellites in open areas just fine, I installed a couple navigation programs- everything works fine ☺, 3G modems are recognized immediately without installing additional software (using the example of the MTS 3G modem HUAWEI E171). The battery is 4000 mAh, lasts an average of 3-4 hours.
To sum it all up brief overview, I will say - I am completely satisfied with the device in all respects, I will naturally use all its capabilities. There is nothing special to compare this tablet with yet, I haven’t used much of a similar model from DNS E71, its resolution is less than 800 by 480, there is no GPS, the price is slightly lower, but it undoubtedly has one advantage - a full-fledged USB host and a separate output for the charger . Score 9 points, minus 1 point due to the lack of a separate charging outlet. The device can definitely be recommended to all fans of Android devices, gamers, and car enthusiasts on a limited budget. Thanks to all.
DNS AirTab P83 | Introduction
Our test laboratory received a tablet from the DNS company, which belongs to the budget category - AirTab P83. The tablet does not feature top-end specifications, although the manufacturer’s statement about support for “3D without glasses” cannot fail to interest you. will become this model tablet from DNS a worthy alternative more expensive "brothers"? We will talk about this in our review.

DNS AirTab P83 | Design and appearance
The design of the tablet can be called "conservative": a black front panel, a gray side frame and a gray back panel made of soft-touch plastic, which feels like rubber and seems rough. The rear camera is on the right top corner, and the front one is in the center if you hold the tablet in landscape orientation. Stereo speakers are located on the rear panel at the bottom. All external interfaces are located on the right edge. All buttons, including the power button and the volume rocker, are located on the top edge on the left. Reaching the volume rocker is not entirely convenient, but you can get used to it, however, in portrait orientation this arrangement of buttons is very good.

The back panel of the tablet sometimes came off during use, but then easily snapped back into place. In the area of the headphone jack, a gap is visible between the side frame and rear panel, which is not very good. If you hold the tablet in landscape orientation, you can see that the display is shifted slightly to the left, but this does not cause any inconvenience in use.
According to DNS tradition, a leather case is supplied with the tablet, but we did not like using the tablet in a case: the tablet looks even more bulky, heats up more, which reduces performance, and the buttons working panel Android is harder to get to.
Included in the package you will receive a tablet, a clamshell case, Charger, USB cable for connecting to a computer, OTG-USB cable, instruction manual.
DNS AirTab P83 | Software
The OS installed on the tablet was not the best a new version Android 4.0.4 Ice Cream. We hope that the next firmware version will be Jelly Bean.

|
|
On the AirTab P83, according to the DNS tradition, many applications are preinstalled, mainly Yandex applications, such as Yandex Maps, Trains, Weather, and many Internet applications for social networks are also preinstalled: VKontakte, Odnoklassniki, Twitter and others. The popular 2GIS application was not spared either: the tablet has an installation file where the region is selected and maps are downloaded. It would be very convenient if the DNS company immediately installed the latest version of 2GIS on its tablets, taking into account the location of their sale.
None third party applications for reading books, such as FB Reader or CoolReader, is not installed, so the AirTab P83 reads all books through a standard office application, and install the necessary program you'll have to do it yourself. Besides standard application For typing, like other Android devices, there is a Go Keyboard that is installed by default. You can use the option that is convenient for you.

The settings are standard for tablets, you won't get any surprises. The only thing you can focus on is the item in the “System” called “CPU Mode Setting”, where you can select one of two processor operating modes: Normal and Power Saving. The second is designed to save the tablet's battery. It should be noted that when the load on the CPU increases, the tablet automatically switches from economy mode to normal mode, so we were not able to conduct performance tests in economy mode. When watching a movie, the economy mode gave another 40 minutes battery life, that is, about 20%.
There is also an HDMI setting, where there is only one item: “Enable auto switch”, which is responsible for automatic switching on HDMI when connecting the appropriate cable. In the input settings item, you can choose to type using the standard Android keyboard or using the GO Keyboard application. All other settings are clear, and we will not focus our attention on them.
DNS AirTab P83 | Browser

In addition to the standard browser, Google's Chrome is installed on the tablet, which allows you to synchronize bookmarks, passwords and other information with Chrome on other devices. Browsers work well, “heavy” sites don’t load for long, YouTube video, VKontakte and other sites are viewed without problems, however, we were unable to take a screenshot of the Flash video being played. The SunSpider test rated the browser's performance at 1539.3 ms. The result is not among the leaders, but the DNS AirTab P83 cannot be considered an outsider either. A tablet is good for web surfing.
DNS AirTab P83 | EBook
The tablet does not have a pre-installed reading application e-books, but you can install the application of your choice. The tablet should read all popular formats, although we would not recommend this tablet for reading due to the TFT panel used in the tablet. Still, IPS panels provide wider viewing angles and better color reproduction.
DNS AirTab P83 | Music
To listen to audio files on AirTab P83, use the Music application. If for some reason you are not satisfied with this application, then you can install the audio player you like if you wish.
DNS AirTab P83 | Video
Since April 2013, we have been using a new testing methodology for testing multimedia devices. It is divided into several parts.
- Popular formats— frequently used video formats and codecs. It is recommended to evaluate their support first
- Images DVDs and Blu-Ray— testing the playback of full DVD/Blu-ray images, including menus. Recommended if you store your media library as images
- Rare formats- less common formats, but still relevant
- Ultra HD 2K and 4K— formats with an eye to the future. Ultra-high-definition video will gain popularity in 2013

The tablet reproduced a large number of movies from our test collection, only some turned out to be “heavy” for the tablet. However, we didn’t really count on Ultra-HD video playback. Installing a third-party player can solve the problem of some videos that cannot be played by the tablet; all films and videos were launched on the standard player. In general, the results can be called satisfactory.
In addition, if you want to play the video on a TV or monitor, the tablet has a corresponding mini-HDMI connector that allows you to transmit the signal. Unfortunately, the adapter from mini-HDMI to HDMI is not included in the package.
DNS AirTab P83 | 3D support
3D technology without glasses is not so common, and not all users are familiar with it. Therefore, we decided to first explain the principle of operation so that readers would not have any skeptical thoughts or doubts regarding this function. The 3D effect is achieved using a parallax barrier, which is applied on top of the screen of a tablet, phone or TV. This barrier consists of a layer of material with thin slits that allow each eye to see a different set of pixels that make up the image. This effect can be seen on some calendar cards, in which the picture changes depending on the viewing angle.
Accordingly, the main disadvantage of this 3D system is the strict limitation on the position of the viewer (perpendicular to the center of the screen), and the resolution is two times worse compared to 2D, since not one image is formed on the display, but one for each eye, then there are two. More detailed information We recommend reading it on the Around 3D website.
Now let's talk about implementing this function on the DNS AirTab P83 tablet. The tablet has two applications for viewing videos and images in 3D: 3D Player for videos and BIPicture for images. We checked the videos and pictures that were originally downloaded to the tablet. We really got a 3D effect; we were especially impressed by the video with a snake that seemed to crawl out of the screen. Unfortunately, the 3D effect cannot be shown in screenshots or photographs.
The downside is the low quality of the 3D image and the long search for the angle from which the 3D effect is most noticeable. We think that not everyone will be able to withstand an hour and a half of watching 3D films, since even after a few minutes the eyes began to get tired. The pictures were also well viewed, although they did not cause as many impressions as the video did. The 3D Player application has several modes for viewing surround video, including support for formats with a vertical or horizontal stereo pair.
Many people are interested in whether the tablet can play 2D movies in 3D. Unfortunately, miracles do not happen. The image from 2D to 3D is poorly converted on the tablet: desynchronization of images for the left and right eyes becomes noticeable, and you will not get a comfortable viewing experience. Therefore, in 3D, we recommend watching only movies encoded in 3D.
We were unable to display Blu-ray 3D in the proposed players, but we successfully played transcoded films in MP4 H.264/AVC with a horizontal stereo pair. However, do not be discouraged: there are many programs for converting 2D to 3D, such as HandBrake. It is enough to convert the video you need using the instructions from the 4pda forum. The conversion takes into account the device screen resolution and stereo pair (vertical or horizontal).
In general, the performance of the 3D function on the tablet can be assessed as satisfactory. It works well and may well attract users who like to watch movies in bulk. DNS AirTab P83 captivates with its unique 3D function, which has recently begun to appear on the tablet and smartphone market, although it is still rare. But before purchasing, we recommend making a personal impression of 3D, that is, coming to the store and evaluating the 3D function in practice. The impression of it is very subjective, so decide for yourself.
DNS AirTab P83 | Camera
The tablet has a 0.3 MP front camera and a 2.0 MP rear camera. The front camera is not encouraging, but it will still be enough for video conferencing. The rear camera doesn't work miracles either, but it does a good job of photographing text, which can then be read.
Below are pictures taken with the rear camera. Click on the image to view the uncompressed version.

We also include a test video shot with the tablet's rear camera. You can download the uncompressed version at cloud.mail.ru (4 MB).
DNS AirTab P83 | Performance
CPU performance
We tested the performance of the dual-core Amlogic AML8726-MX processor of the DNS Airtab P83 tablet using Linpack. Results are in millions of floating point operations per second (MFLOPS).
CPU performance is quite typical for a modern 2-core processor.
Overall system performance
We used Smartbench 2012 1.0 to evaluate overall system performance. These tests are very similar to the 3DMark and SysMark suites in that they provide simple and easy-to-use performance indexes for two categories: productivity applications and games. On the other hand, a synthetic test may not accurately reflect the actual performance of applications and games.
You can compare the tablet's results with other smartphones and tablets at http://smartphonebenchmarks.com/
The performance of productivity applications (green bar) is at a quite decent level for a 2-core CPU. Graphics performance remains in line with many other "budget" tablets, although don't forget the slightly higher resolution of 1280x800, which is good for an 8" diagonal. Overall, the tablet should handle Android games, with the exception of the most “heavy” ones. But we will return to this issue in our gaming tests.
JavaScript Performance
SunSpider is a JavaScript benchmark that demonstrates both the performance of the tablet's JavaScript engine and (to a lesser extent) processing power. hardware. A poor implementation of JavaScript on a very fast tablet can ruin the overall performance of the platform. And at the same time, an excellent implementation of JavaScript will allow you to effectively use even slow systems. However, today the main implementations of JavaScript engines are becoming closer to each other, and developers are borrowing all the best ideas. JavaScript tests are single threaded due to the nature of browsers. The SunSpider benchmark avoids many of the micro-benchmarks we see in apps like GeekBench, yet the benchmark attempts to evaluate CPU-sensitive tasks found in real-world web applications.
Below are the results of SunSpider 0.9.1 on tablets and Android phones. Android devices use Google V8 JavaScript engine
The smaller the result, the better. We got 1539 ms, the tablet will not slow down even when loading “heavy” pages.
Quite a worthy result.

CPU performance is on par with other "budget" tablets, second only to the new 4-core models. The same can be said about GPU speed. Performance is not record-breaking, but for a resolution of 1280x800 it is quite good.
Relative Engine
This test was created “for growth”, no existing Android-based devices should show really high results, the graphics level is much higher than the average gaming one, so even if the results here are not the highest, in real games you can get very good results. Consider that 60 fps in this test is already Xbox 360.
The result was 6.4 fps. You won’t be able to play “heavy” games, but the tablet can handle undemanding games.
Network Bandwidth
We tested network performance using the IxChariot test. We used an 802.11 b/g/n router with 1 Gbps ports. The tablet was located about 1 meter from the access point. We tested the maximum available network mode (802.11g or 802.11n), at this time there were no other active transmissions, and no interference was detected in the network coverage area.
The result is not the best we got throughput only 7.9 Mbit/s, although for many competitors it is 20-30 Mbit/s. Apparently, the tablet does not have the fastest WiFi module or an unsuccessful antenna configuration. However, for the Internet such speed will be enough.
DNS AirTab P83 | Game tests
Test results do not always correspond to real performance, so we decided to conduct tests in real conditions.
Three applications were selected for this purpose:
- Cut The Rope is a casual game with simple and beautiful animations
- Epic Citadel – demo of the Unreal engine with built-in benchmark
- NFS Most Wanted – a modern game with “powerful” graphics
These tests test performance under a variety of conditions and measure real-world performance.
In games, frames per second (fps) is an important factor. The higher it is, the smoother the game feels. Frame rates below 30 fps can lead to stuttering and other unpleasant consequences. Frame rates below 15 fps turn the game into a slideshow and you'll hardly be able to enjoy it. We took the average frame rate throughout the test run in the selected game.
Cut the Rope
We decided to test the tablet on ordinary casual games that many people play to have a good time. Since the user can play them for hours, then good frequency frames per second (fps) is an important indicator, because not everyone can watch a jerky picture for many hours. We tested the tablet's performance on the game Cut the Rope HD.
The result was 49 fps, which is more than enough for comfortable gaming on a tablet. So the DNS AirTab P83 tablet copes well with casual 2D games.
Epic Citadel
We have added the Epic Citadel gaming test, which is a demonstration of the capabilities of the Unreal engine from Infinity Blade for Android OS. The test has different .apk and cache for different GPUs, so you need to take your versions for the test. We used latest version 1.05 for Mali-400, downloaded from Google Play. The test was carried out only in High Quality mode. We excluded the High Performance mode from the tests, since the results differ slightly, and we are interested in the tablet’s performance relative to other models. You can see the results below.
The result of 26 fps is close to the magic threshold of 30 fps, but still falls short of it. So the tablet is still a bit weak for modern shooters, but if you get used to it, you can play it. But from time to time there will be jerks.
Need for Speed: Most Wanted
To test the performance of "heavy" and demanding games, we chose NFS: Most Wanted. To install this game, you have to download the cache for each device separately, it was not possible to find something common for devices even with the same GPU, and the cache itself “weighs” 2 GB, an archive of 600 MB is downloaded. Therefore, get ready for the fact that you won’t be able to play immediately after installation; you’ll have to pump out the cache.
Alas, the tablet cannot cope with “heavy” games: the result was only 12 fps, which is very low for a comfortable game.
DNS AirTab P83 | Battery life
Thanks to a 2 A power supply and a battery capacity of 5000 mAh, the tablet charges quite quickly - a little over three and a half hours. However, battery life in games and movies is also low - you will get between three and four hours. All tests were carried out at maximum brightness, which is not at all necessary during operation; you can gain a few more tens of minutes by reducing the brightness. Also, switching to economy mode allows you to add about 40 more minutes when watching a movie or reading web pages.
DNS AirTab P83 | Conclusion
The tablet from DNS AirTab P83 will completely satisfy ordinary users that do not place high demands on technology. The package is quite complete, but an adapter from mini-HDMI to regular HDMI would be nice. The case has a number of minor flaws, but overall it looks reliable, although not everyone will like the rubberized plastic. It is worth noting that during operation the tablet gets very hot even under moderate loads, making it uncomfortable to hold in your hands. Perhaps this is due to the housing, which does not provide proper heat transfer. Accordingly, the tablet heats up even more in the case, which affects performance (it decreases). The tablet itself looks neutral, but the tablet's display is shifted slightly to the left, which perhaps indicates that it works correctly in portrait orientation, although in landscape orientation the display shift is not so noticeable. The location of all buttons and external interfaces is standard and does not cause any particular complaints.
The cameras don't set records, but for shooting from time to time, when there is nothing else at hand, they are suitable. Front camera enough for video conferences, and the rear one for taking pictures of texts even in dim lighting. The speakers are loud, you can hear everything well and clearly, but maximum volume It is clearly noticeable how the upper frequencies begin to “crackle”, which makes listening to something or watching a movie uncomfortable, so we recommend not setting the volume to the maximum. The location of the speakers is good for watching movies if the tablet is mounted on a stand, otherwise your hands will cover the speakers. The screen is not happy high resolution Retina, although for an 8" diagonal 1280x800 has already become a standard. But you can watch HD movies comfortably. It’s a pity that the panel is TN and not IPS. As a result, the horizontal viewing angles are quite acceptable ( landscape orientation), but the vertical viewing angles are not encouraging. The sensor of this tablet turned out to be worse than the previously tested one, which costs almost half the price, the sensor pitch is large and the tablet “didn’t guess” some touches, but you can use it, the comments on the sensor are not so significant.
In terms of performance, the tablet is inferior to the top “budget” models with an 8" diagonal, which have already switched to four cores. But you can’t classify it as an outsider either: we get a typical 2-core “average”. The 7" tablet from the same DNS company has better performance, than this model, although the price is slightly lower and the screen size is smaller (as is the resolution 1024x600). In general, the tablet's performance is sufficient for all basic functions, but it is better not to count on demanding 3D games: this was shown by both synthetic and game tests.
In the case of the tested DNS AirTab P83, the manufacturer decided to attract buyers not with performance, but interesting function, which distinguishes the tablet from other competitors. Of course, we mean glasses-free 3D support. Quite a tempting offer, and the manufacturer claims not only support for this function, but also the ability to convert 2D images to 3D. We were skeptical about this information, so we decided to test it in practice. First of all, we launched a 3D video, which is already available on the tablet, and, frankly, we were surprised: the video was really three-dimensional, and it was quite comfortable to watch. Not all 3D formats are supported (this includes Blu-ray 3D), so be prepared to convert movies or search for videos in in the required format. But the process is not difficult. We weren't convinced by the 2D to 3D conversion, but we weren't expecting miracles in this regard.
Despite the average hardware, the tablet plays most movies well. “Heavy” films 1080p 60 Hz, Hi10P and Ultra HD are less suitable for a tablet, although if you select players, you can “pull out” some of them. So we don't recommend playing movies with resolutions higher than 720p, but given the screen resolution, there's still no point in playing 1080p or higher. In the case of other unplayable files, the problem may be resolved by installing an alternative player. By the way, the tablet does not normally support external hard disks, which today is a serious disadvantage, since many users already prefer a portable HDD as a storage device due to the large volumes of films of modern quality and format.
Charging and battery life are also important criteria when choosing a tablet. Thanks to a good 2 A power supply, the AirTab P83 tablet charges quickly: about 3.5 hours. However, I was disappointed by the rapid discharge of the battery: when playing an HD movie, the tablet lasted a little more than 3 hours, and in the game for 3.5 hours. Lowering the screen brightness can improve battery life, as can putting your tablet into Eco mode. In terms of battery life, the AirTab P83 tablet again lost, the battery testing results of which were good. Judging by the presence of 3D, the tablet can be classified as a multimedia line, so I would like a longer battery life.
Alternatives. It is worth mentioning the performance leader in our laboratory: . In terms of screen size and resolution, it is comparable to the P83, however, the matrix used in the Parus Quad is narrower than IPS, which gives better color rendition and viewing angles compared to the TN in the P83, and the results of many tests go far ahead. This is primarily due to the 1.6 GHz quad-core processor and 2 GB of DDR3 memory, but the price remains at a budget level and is not much higher than the cost of the AirTab P83. Let's wait for a 4-core 8" tablet from DNS!

The DNS Air Tab e101 came into my hands as a replacement for another more advanced DNS tablet that was handed over under warranty for the duration of the examination, after which, I hope, my money will be returned. According to the idea, I should have been given the DNS Air Tab e101 fully equipped, but there were no headphones or a case in the box.... Well, that means the DNS Air Tab e101 has such a complete set, if not, let the DNS employees correct me. So, a little about specifications: 1.2 GHz processor, 1 GB RAM and 8 GB Flash memory and support microSD cards, TFT display 10.1" diagonal and a resolution of 1024 by 600 pixels, built-in WiFi module, Android 4.0, two cameras, the most powerful of which is 2 MP. The tablet feels quite heavy for its size, but not critical. DNS Air Tab e101 feels very solid to the touch. Glass display screen,
Which probably gives it weight. Touch control
on the tablet DNS Air Tab e101 is not ideal and is very “thoughtful”, sometimes you have to press twice. On complex games, the DNS Air Tab e101 clearly slows down + the sensor is thoughtful.... In general, you don’t even have to try to run heavy “toys”. The battery is fully charged in 5-6 hours, and discharged, with active use, in three hours. I didn’t really like how Odnoklassniki looks and works on the DNS Air Tab e101, but it’s tolerable. There is no question of using the DNS Air Tab e101 as a mobile device to access the Internet, since I did not find a slot for a SIM card, then I read the technical specifications and realized that I was looking in vain. So, sitting on a bus or with friends on a bench,
You won’t be able to, for example, view your email unless, of course, there are WiFi access points nearby.
So, my conclusion: as a workhorse for checking mail and social networks at home and at work, the DNS Air Tab e101 is quite suitable, if of course there are points there WiFi access. It is also suitable for simple games and listening to music, watching TV, radio, all at a fairly average level. The appearance of the DNS Air Tab e101 is quite attractive. So if you need a simple tablet that you don’t mind losing or breaking, then the DNS Air Tab e101 will suit you. But it’s worth remembering that buying products from little-known brands is always a lottery; if you’re lucky, it will work, if you’re unlucky, it will break, and it’s good if it’s within the warranty period!
Installing ClockWorkMod Recovery and getting root rights on an Android tablet is not very difficult. Just follow the instructions and you will succeed. In this matter, we will be helped by ClockWorkMod itself, the superuser application, drivers for our tablet and Odin program. I’ll say right away that the described method is not suitable for everyone, but for most owners of Android devices.
First, let's understand a little about what ClockWorkMod Recovery and root rights are.
ClockWorkMod is a modification of the standard Recovery mode, which allows you to install custom (modified) firmware (how to install firmware on a tablet), perform a data reset (wipe), restore and create backups your data and much more that you will never do on your tablet. ROOT rights- analogue of a computer administrator in Windows environment. Allows you to modify and delete files Android systems. If we again draw an analogy with Windows, then this is something like the ability to go into C:\Windows and change hidden files and folders. Using the Superuser helper application, you can grant root rights to other programs.
I will not divide the instructions into two parts and write separately about installing ClockWorkMod Recovery and getting root rights on tablets. We will do all this within one instruction at a time. Let's get started.
Installing ClockWorkMod and root rights
1. Download it yourself ClockWorkMod from clockworkmod.com for your tablet model. Just find your model in the list, and click on the version number in the second column, called Download Recovery. Choose what to download very carefully. If you download ClockWorkMod for something other than your tablet, there will be problems. Move the CWM file to a folder whose path does not contain Russian letters.2. Download the program SuperSU version 0.96. In principle, you can search and download a later version of the Superuser application, but the suggested version has been tested many times, so it can definitely be trusted.3. Download Odin from here.
4. Download drivers for your tablet from the manufacturer's website (Acer, Samsung, HP, Sony...) and install as administrator.5. Disabling the antivirus and all the left programs in the background, such as player, browser and so on.
6. Copy the one downloaded from step 2 SuperSU to the tablet's memory card.7. Launch Odin and click on the button PDA. Select our ClockWorkMod in the window.
8. Turn off the tablet. Next, press the button Volume+ And Inclusion. Hold until the menu appears. If you need to confirm the action, click Volume-.9. We connect the tablet to the computer in this state (it’s better to connect to the rear USB port if you have a desktop, for laptops it doesn’t matter; and use the original cable, and not the one bought on Ebay, it’s unclear which one). Odin should respond to the connection of the tablet by writing the port number and changing the color of the window to yellow or blue(depending on Odin version).
10. Uncheck Auto Reboot in Odin, do not touch other settings. Click START.eleven. After completing the firmware, turn off the tablet and turn it on again by clicking on Volume- And Inclusion. Keep them pressed again until the menu appears.
12. We entered ClockWorkMod, which we installed a couple of minutes ago. All that remains is to install the Superuser application. To do this, select from the menu install zip from sdcard -> chouse zip from sdcard, and select our SuperSU, which we downloaded in step 2. Confirm the choice.
13. After installation, select reboot system now. The tablet will reboot and you will have root rights and ClockWorkMod Recovery installed on your Android tablet.
If you are unable to install CWM and get root rights, then your tablet does not do this as standard, and you will have to find out how to do it yourself.
