Exclamation [Q] Galaxy S3 Touchscreen not working

Hi people!
I flashed a wrong custom recovery on my GS3 (it was a cwm for Note 2but I lost that part in the thread), when I turned on the device the start screen froze and I took out the battery. I flashed an official fw via odin (since after that I couldn't enter recovery mode) but when the device started the first boot config I noticed that the touchscreen wasn't working... I performed a "deep clean2" and flashed an official fw again: nothing; I performed another deep clean2 and flashed a cwm in order to flash a custom rom + googy max kernel (I thought the wrong recovery messed up my kernel and tried this way) but nothing worked.... is there someone who can help me?
one more thing: I tried flashing again an official fw and then performing an "Emergency restore" via kies but the program can't recognise my GS3 due to the flash counter > 0 (i think)....

I'm in Your hands people!
