Hi
I have a Chinese 10" Tablet that boots with a Samsung Splash screen and shows N9106HD.
It is 'rooted' but I do not have write access with ADB
Recently I installed a couple of App2SD program. A reboot worked, then I attempted to change the 'E-mail' app from a system app to a user app.
The tablet rebooted itself and since then attempting to start results in a bootloop showing a flashing "SAMSUNG" on the screen.
The tablet has only 3 buttons, power, up and down.
When stuck on and showing the splash screen, I can connect to the device with adb, however, have limited access and am unable to view/copy data or system (I have been trying to use QtADB for this).
There are 2 alternative boot methods that open another screen:
1. Holding 'pwr' and 'up' simultaneously at boot. This gives a menu of:
Android System Recovery <3e>
Reboot System Now
apply update from ADB
apply update from sdcard
apply update from sdcard2
apply update from cache
wipe data/factory reset
wipe cache partition
(I have wiped the cache partition successfully with this)
2. Holding pwr and 'down' simultaneously at boot.
This gives a menu only in chinese. Trying to access through this menu it seems to be for hardware tests.
Running QtADB starts with an error:
"adbd cannot run as root in production builds so You can't do anything with /system partition. Run Anyway?"
I have found this application adbd-insecure ([Only registered and activated users can see links Click here to register]), however, as I only have some sort of basic recovery access and do not seem to have write access I do not know how I could get this to install so that I could have write access.... catch 22.
I have taken the SDCard out of the tablet for now. It has a 2GB 'Internal' Memory and a 16GB 'Phone' memory. The phone memory is treated by the App2SD as an external SDcard I think.
Plugging into linux with it sitting on the 'samsung' splash screen shows the following device details:
Bus 005 Device 022: ID 0bb4:0c03 HTC (High Tech Computer Corp.)

Attention: Requests for confirmation on the device screen are possible.
(However, the screen is stuck on the 'samsung' splash)
Can someone please help with recovering this tablet?
TIA
