Solving the Accurator problem on Lenovo Tab 2 A7-10F

When you flash your device, almost always you visualise seeing your device running the original firmware. You remember the good old days when your tablet used to run the stock ROM, bug-free and......
'Oh no!'
You see something that you hadn't expected.
Many a times, it so happens that the 'firmware' for a particular device isn't actually made for that device. Most of the times the firmware is fully functional on the device, but not to perform the functions that the device was designed to perform.
One such device is the Lenovo Tab 2 A7-10F. It is a cheap, but an equally respectable multimedia tablet having a 1.3 GHz Quad core MTK 8127 chipset with 1GB of RAM. Here in India, many educational institutions use this tablet as a digital learning aid for students, but at the end of the year, flashing it becomes a big problem.
You simply don't get genuine Android 4.4 Firmware for this device.
You do get firmware for the device. No doubts. But flash the firmware and you see a white screen on startup, with the word 'Accurator' in Chinese.
I believe it is an educational app which was built for a 10.1 inch Chinese tablet, which also runs on MTK 8127. This app practically immobilizes the Android system, and this fact is evident when you have a look the Settings application.
It looks like a human without his skeleton.
To me, this app initially looked inpregnable. But then, just then, I discovered a bug in the app. All that you need, in addition to the tablet is a Wi-Fi hotspot-no kidding.

Steps to get past the Accurator app

  1. Switch On the tablet and wait till you get to the Accurator home app.
  2. Now go to the settings.
  3. Though everything is in Chinese, you can change the language, atleast that of the settings app. Search for the Language Settings[it usually is accompanied by an icon consisting of a rectangle enclosing an 'A'.
  4. Open the first option and select 'English' from the popup.
  5. Go back to the Settings home page, and open Wi-Fi. Switch on your router, and connect the tablet to the network.
  6. Go back to the settings and open Display.
  7. Open Wallpaper, and from the options, select 'Gallery'.
  8. In the Gallery, somewhere at the top will be a symbol of a Camera. Touch the symbol, and the camera opens.
  9. Now shoot a short video. It doesn't have to be about anything. Just a video. Max 2 seconds.
  10. Swipe to the left, and you'll probably see your video.
  11. Open the video. You get an 'Open With' dialogue box with two options, Browser and Video Player. Select Browser, and then touch the 'Only Once' option.
  12. Now you get the browser. It is rather impractical to use, but that isn't a problem. In the Address bar, type; google.com
  13. Once you get to Google, download two apps; a launcher[preferably Apex or Go Launcher] and the Non Root Button Savior app. Install both. Don't open the launcher. Just open Button Savior.
  14. Now activate Button Savior. Almost immediately, you can see a small trigger button, usually on the right edge of the screen. Touch the trigger, and you can see the Home, the Back, and the Recent Activities button, along with some other functions.
  15. Touch the Home button to go back to Accurator.
  16. Go to Settings, and change the Home app to the launcher you just downloaded. Press Home button to go to the new launcher!
However, we still can't access the all-important Status bar, and the GApps, which is a big disappointment. Even viewing the notifications is impossible without the help of Gesture support offered by 3rd party Launchers. So it is better to root the device, and flash the debloated Lollipop update for the device using the stock recovery [for the Lollipop ROM go to XDA]
But if you are happy without GApps, so be it!
