a little help please

[dontony]

my stupid hard keyboard is acting up, sometimes it won't type anything on the screen and it doesn't respond to anything i type, other times it will type just fine, other times it only types 12 characters then it doesnt respond at all, and sometimes it will type whichever letter i hit a million times non stop. i did a hard reset but still the problem continues, is there a hack or cab file to fix this? or is the device damaged? thanx in advance
