Bold keeps rebooting when Mobile Network is on. HELP!

I hope someone can read through this and help me with my device.

I updated from Curve to Bold 9900 few months ago. My Blackberry Bold was working fine up until last night, and I never had this issue before, since I have been a loyal BlackBerry user for past 7-10 years. . All of a sudden it keeps rebooting by itself, over and over again. As soon as it turns on, it goes off and keeps rebooting again. It does so when my Mobile Network is turned on. If I turn it off it doesn't shut off and it is fine. It does this when the SIM card is in and out.
Can someone please help me with this. I'd appreciate it. 

I'm running on 7.1.0 2435 Bundle OS

Thank You

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.

Good luck and let us know!
