After many failed attempts to reflash this MID-2330-S tablet (similar looks to YeahPad A13), I finally found an almost perfect ROM. However, the touch input is inverted. Here's my lsmod:

Is there any way to fix this without installing another ROM, or if possible, can I edit the current drivers to correct their X and Y values?

Alright, since got no replies I searched around the forums and found a method that edits the script.bin and script0.bin within the firmware. Tried unscript, edit, script method, flashed the new ROM, and ended up in a completely blank screen (not even backlight). Tablet seems to turn on, though I have no way to determine if I broke anything else since the display is out.
