Is flashing FT5406 touch controller firmware possible?

Hi everybody!

Today I had a problem with my tablet Onda Vi40 Elite v3 9.7" 1024x768.
I wanted to update it to the last official firmware (http://file2.mydrivers.com/ondata/do...V1_v1.4rc3.rar), and accidently I flashed a firmware I was analyzing from KNC-902 that has almost the same specs (http://pan.baidu.com/netdisk/singlep...4378_480365957) using LiveSuite 1.07.

The firmware flashed ok, but my touch was not working (it was normal, because it wasn't the same hardware).
So I took the correct firmware from Onda and flashed it to my tablet. The problem now is that the touch keeps not working!
I have looked around on internet, and found maybe a similar behavior on Ainol Fire tablet, where the firmware update also flashed a new touch IC firmware.

I already have opened my tablet and found the touch IC controller (FT5406EE8) and I think firmware for it to (http://forum.xda-developers.com/show...5&postcount=22).

My question is: how can I know what is the right firmware for my touch IC controller (I have seen more than one for 1024x768) and how can I flash this firmware again to my touch IC controller?

Thank you for any help! :)

Regards,

Michael
