Blackberry 8520 Curve doesn't turn on

My blackberry 8520 worked just fine the night before and I could see that the battery was low and overnight the phone turned off.


I tried to charge the phone in the morning but the phone wouldn't turn back on. I tried using another fully charged battery but the phone starts, reaches the booting stage where the Blackberry logo and the loading bar appears on the screen. 


But just as the loading bar goes 2 notches higher the phone switches off and boots again, coming back to the loading bar and repeating the same thing.


Kindly advise what can be done to salvage the phone and/ or the data in it.

Hi and Welcome to the Community!

I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.

If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.

But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.

You may also need the use of these tricks:

Do prepare yourself for the possibility that your data may already be gone from the device. No devices designed, built, and operated by humans can be expected to be perfect. Hence, backups are neither a reactive nor optional activity...the time to do backups is before things go wrong, not after.

Good luck and let us know!
