Hi, my daughter's 9300 curve started to have intermittent problems with the centre button freezing. Initially for a couple of weeks, re-booting sorted this. Then the phone started re-booting itself - each time the button would work for a few seconds then freeze. Having backed it up, I have wiped the phone using BBSAK and re-installed 6.0.0 (bundle 2949) using blackberry desktop 184.108.40.206 (twice).
Now the button doesn't work at all and I can't think what else to try. Does it sound like a hardware problem? Any suggestions before I take it to a shop (or replace it).
Update - after a night's sleep. The phone is still locking and rebooting constantly - followed the 'how to recover a nuked blackberry' instructions, i am able to interrupt the rebooting, but as soon as the re-install is complete, it locks and starts rebooting again. All happens too quickly to get to the security wipe option.
