ok so my phone hasnt been working this past 2 days, the keyboard is not responding and the screen bright up whenever it feel like it, but i have 8 text messages and i cant see them so the question is is it possible to back up them SMS TO THE COMPUTER and wipe out the device and load another os?
1. Yes you can back them up to a computer. Use BlackBerry Desktop Manager.
2. You can also use BlackBerry Desktop Manager to restore the data from the backup.
3. The "keyboard not responding" is typically a hardware issue (typically moisture) and not a software issue. So it likely will not get corrected by "load[ing] another os".
