I have a k610 with a very stranbge behaviour, the keypad is weird, very crazy, you tyoe one key and works another 1 or two at same time, sommetimes a key doesnt work , etc.

I fllashed, repaired EROM, cleaned keypad, PCB, and nothing.

I would like to know if a damaged GDFS could cause this, so I would proceed to repair GDFS.

I would read secunits off the phone, flashed a working GDFS and restore SecUnits back.
But because it is a risky process I would like to know first...
clear now ?
