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.

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!

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.

Make sure you're rooted and have a working backup.

11,141,690 in total · 8,610 in the last 24 hours
MD5 checksum:
de4f0dc569f96dbcc5668d40fa76040b
Uploaded on:

Now either use an android terminal emulator or ADB and run these commands

Now you can install the Xposed framework.

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.
