(Q) Downgrade touchscreen firmware
I did a big mistake and upgrade to 4.3 before I done the SimLock option and now I have a ver nice phone siting ton my shelf.
I've looked at Remove SimLock option and try for the last 2 days to make the SimLock work on 4.3 include swapping files and more but nothing helps.
I found out that the only option I have is to go back to stock 4.2 version but after I flash it the touchscreen is not working.
I understand that the problem is with the touchscreen firmware and I need to find a way to downgrade also the touchscreen firmware after I'm downgrade the Rom.
I found a post on other device that someone post there a solution how to downgrade it but it's not good for our Htc One and also it's not for going back from 4.3 to 4.2.
I would like to know if someone can help me or just tell me if this is possible .
The only thing I want is to be back with stock 4.2
