Re: BlackBerry 9790 keeps rebooting

I am having the same problems. My 9790 keeps rebooting and draining the battery.  Any advice?

Re: BlackBerry 9790 keeps rebooting

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:

Good luck and let us know!

Re: BlackBerry 9790 keeps rebooting

Thank you sdgardne!  The Safe mode did not work but the Application Loader method did.  I took the battery out and inserted the USB cable.  I was prompted to cancel, repair or retry.  I opted for repair and device software was reloaded.  The initial attempt was not successful but I inserted my battery and then the device software was reloaded.  Seems fine now.  Once again, thanks!
