hi guys - im having issues with the proximity sensor on my htc desire s...seems to be a common fault on these...anyway, i want to disable it and i undestand the phone needs to be rooted..im perfectly happy with my phone and do not need custom roms or anything else just want to disable the proximity sensor...my phone has a locked bootloader and i understand it needs to be unlocked first..can i just root the phone only without doing anything else to it ? ta
