when i check the touch key firmware version using *#2663#, the touch key firmware part is blank. No "phones touch key FW version" No "parts touchkey FW version" and No " touchkey FW update". I am using orginal Display. also my pressure sensor ic " part No U204" is tear off from board. but all other functions working normal. is there any connection between u 204 and touch keys? I check the display with another board and touch buttons working fine. try so many firware. but its blank while checking.. please help
