Hi there,

I've got a huge problem with my Android Tablet. It's a cheap Chinese Allwinner (P76TI ?) 8" one. First it was working fine. I changed vold.fstab with a script to install apps rather on SD card than on the limited internal storage (the built in one was already split up into "int" and "ext" ). I also changed the build.prop to get access to more apps on Play. It was still doing fine and also survived several reboots after installing Chainfire3D.
Problem:
Suddenly it had reverted all settings when i booted it up. It was working but language settings, apps and more had vanished.
I have not touched any reset or whatsoever button. Even worse: it does not keep any settings! It will reset to this state every time i shut it down.
Next thing is, the internal memory is "gone". It says 0.0B available and 35MB used for apps. 2nd, 3rd, 4th memory are working fine.
It will only install very small apps. I could not get it to install Chainfire3D.

I have tried to replace the fstab with the original one but since i only used a prewritten script I don't know how it should look like. (And I don't know if this really causes the problem)
Through ADB I ran the cf3d_uninstall.sh, so that should be okay now.

I have no idea of how to solve this riddle. And I don't know how all of this is connected. Which, if any, of my changes caused it? And is the storage thing related to the loss of settings?

Please, could anyone help me?


This is how fstab looks like now. Should I just interchange the devices of the fiirst 2 lines?

EDIT: PROBLEM SOLVED

Busybox seems to cause such problems with some of those cheap tablets.
A simple: ~mv /system/bin/busybox /system/bin in the ADB Shell solved all problems
