Backup/Root/Recovery

DISCLAIMER:
Rooting your phone and using custom Recoveries and ROM's have risks and may result in bricking your device, and has nothing to do with Google or the device manufacturers. In case of any mishap I am not responsible if you brick/ruin your phone in any way.
Basic computer skills are required and minimal knowledge about the phone and phone utilities also.
Make sure that whatever you do, you are doing it at your own responsibility.

How to backup of your stock ROM, install CWM and Root your device.

Requirements

Steps
  1. Download and unpack IntelAndroid-FBRL-07-24-2015.7z
  2. Power off tab.
  3. Hold Vol+ and press Power on the tab 5-10 seconds
  4. You can see logo about 10 sec and after that DROIDBOOT will load
  5. Connect USB cable to PC
  6. Run launch.bat from IntelAndroid-FBRL-07-24-2015 folder
  7. Type ACCEPT and press Enter
  8. Type 5 and ENTER (cwm.zip)
  9. Type T3 and ENTER (or T4)
  10. CWM will load after 10 sec.
  11. Select backup to external sd card.
  12. After the backup is complete, copy it to the PC to ensure it's safe.
  13. Follow steps 1-10 again and go to install zip from sdcard or external and select the SuperSU zip file and flash it.
NOTE: DO NOT FLASH ANY ROMS WITH THIS RECOVERY IT IS ONLY TEMPORARY. I DID NOT TEST XPOSED SO BE CAREFUL.

How to fix touch!

If you unbricked your tablet and your touch isn't working, there is no need to worry. @andrei_kr has provided a guide on how to fix that touchscreen. Credits to him.

NOTE: If your touch is working then do not try this, it will mess up your touch!!

You probably got this touchscreen issue by flashing a different kernel with incorrect drivers.

Now your configuration is likely to differ from the native. You can view the konifig in command prompt or in the terminal :
Code: 
cat /proc/gt9xx_config
(only mtk) or using the gtp_tools apk (it is in the attached file below).

It starts with the byte sequence: 0x41 0x1C 0x02 0xC0 0x03

0x41 - 65 version
0x1C 0x02 - 540 horizontal resolution
0xC0 0x03 - 960 vertical resolution

Touch must somehow work to press the button, if there is support otg, then it's easier, you can connect a mouse.

1. Install the gtp_tools_v2.6_20140126_special.apk
2. Go to the option Firmware update. Click refresh, see IC Version: 913_1020 then touch GT913 firmware and 1020.
3. Go to the option Config Settings, press read, the data were considered. Under Normal Config we have:
65 version
540 horizontal resolution
960 vertical resolution

4. Click browse, select click browse to the native config.
5. Native configuration take from your device, in the same paragraph, press the save (saves the backup config file). Native configuration for Fly IQ446 in the attached file. Press send.
6. If nothing has changed, look at the version you have and native config. Then change the version of the file in the native config in your hex.
Example: 0x41 = 65 home, a stranger 0x49 = 73 => replace the 0x41 to 0x49.

First want to say much thanks for this thread, it was getting frustrating trying to find a solution.

I have encountered a slight issue trying to unstuck 2 of these devices.
neither have been rooted and are stock devices.
i cant seem to get cwm to locate the backup that you supplied.
do i need to copy it to the cwm backup folder on my sd card?

Yes you do. Copy it to your sd card. Btw if your device is stock why do you want to restore this one?

NuVision TM101A510L

Will this method work with the NuVison TM101A510L. It seems like a lot of work to do if I'm not sure about this model. Also I have a problem with this model overheating and crashing when I play Pixel Gun 3d and it's pissing me off. I just fired off a curse filled missive to NuVision support. They don't even list this model on their registration page and it seems they have no faith in this model. I will never buy this brand again, in fact I would recommend against it to my customers. I've used Azpen tablets with no problem rooting or playing Pixel Gun 3d. I took a chance and I'm so damned sorry I did.

I think the models numbers are specific so I can't say for certain that this will work with your tab. Try the fastboot/rooting procedure first and then maybe you can just restore the system partition only not corrupting the boot/kernel.

You are using the fastboot method correct? If the recovery script says finished as in no errors show on the screen then it could be the device itself. What do you see?

ill let you know just as soon as i can get back to working on those devices... im prety sure if memory serves correctly, that I was getting some errors regarding unable to mound sd or ext sd. I could be wrong but thats what comes to mind.

Im up to my neck in jobs on other devices. (rooting galaxy S5, changing imei on another S5, IMEI change on a LG Stylo 2 plus, Galaxy Tab 2 system issues need to diagnose, and several screen and lcd replacments)

STUCK

ok so i have a little time to work on these....

When i run the launch.bat and get to fastboot, it goes through the instalation and everything checks ok till the very end where it says failed cause too many links.

At this point im unsure if i just need to try flashing the supersu zip like it instructs but having tried befor it had no luck.

after ive flashed super su, when i go to restor the working backup i see a list of backups... including yours but when i select it i always get :

checking md5 sums...
md5 mismatch!
what now?

(i tried just flashing the boot but even that comes back with same error)
I know on other devices the recovery is an img file any the one you provide is a rar... i extracted to my desktop and was gonna try flashing with abd/fastboot but since its not an img file, im thinking it wont work...
any thoughts?

Im still unsure how to flash the recovery that u supply in the section for fixing bootloop....

The too many links error is common for this device. Touch doesn't work with TWRP on this device so CWM is out only go. You can root and using cwm like any other root method.

    Unbrick your Tab!

    To unbrick your device all you simply have to do is go back to the CWM and restore your backup that you created earlier. If you don't have one, here is a copy of a working backup ---> Google Drive. Credits to @andrei_kr, say thanks!
