Sorry guys, been sick for some days. I was wrong, Fosser was greeting another guy : redeyedjedi
Impressive you got this booting! I'll keep my eyes on this for sure
All i did to manage to get to the android app launcher, was like i said, to use some tricks.
1st i've edited the install script with the correct folders, then the build.prop file.
It was always stuck at the CM logo, but i had no glitch.
Couldn't get an adb debug log, coz the computer i was using wasn't mine.
So i tried to factory reset the tab, install a working 4.1.2 rom, then flash this rom (without wiping anything).
That's how i managed to get it booting... but i must reckon, i don't think that this rom is going to work on our tab.
At least i'm way to sick to push my investigations much further.
Just popped in to let you know how i got it "semi-working" and don't waste your time.
