ive been facing an issue with my bold 9790 ever since i have updated to 7.1, the phone just reboots on its own as well as the battery keeps draining faster than usual. so i have tried everything read on these support forums and still did not work. I finally downgraded to its original software but the problem is not resolved. was using my phone earlier after downgrading it, all of a sudden " battery too low for radio use" at around 65% charged" and it rebooted, from there it starts its routine of rebooting. I
s it a software problem or could it be the battery that has gone bad? I would really appreciate if you guys could help me, i even tried contacting the blackberry team on twitter but no replies as yet since the past 3 weeks.
Hoping to hear from you guys soon

Hi and Welcome to the Community!
Your theory might be correct...it is possible that your battery or BB has experienced a problem...to test, this sequence is needed:
The results of this will indicate if it's your BB or your battery that has the problem.
Otherwise, I recommend that you attempt to boot into 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 one of your add-on or 3rd party apps is the cause. So, 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 something else is wrong. Given what you describe, I doubt however it's an OS fault...but it's not impossible. You might want to try other OS packages to see if others perform better for you. You also might want to perform a "bare bones" OS install process to see if you can narrow down the cause.
Or, if your device is still under warranty, you may instead want to skip self-diagnostics and head over to your warranty service provider for formal support.
Good luck and let us know!

Sorry for the late respone. I received a new battery on friday, and it was working fine until yesterday when i updated my software back to 7.1 it has started to go off and on by itself as the battery reaches a level of 40 percent. I seriouly hope that this has not affected my new battery as it costed me quite a bit. I reckon the previous OS of 7.0 was much better and was working perfectly with my phone. Im currently using orange network and trying to downgrade it and it is not possible. I had a friend do it for me before but is not currently in town. Is there a way i could downgrade from the version 7.1 bundle 2239 to the original version which was with the phone? and it seems not to be a problem with 3rd party applications as i used it in safe mode and was the same thing.
i hope you could help on this now, and how i can downgrade my OS.
Thanks and hoping for a reply .

Oh!! That's a shame...by "known good", I never mean "new". You see, while rare, a new battery certainly can be defective. And it's much less expensive to conduct the test by finding someone with an identical BB who has no problems...and trade batteries to see what happens.

Unfortunately, unless you happened to take note of what that original version was, it'll be impossible to tell you what version to select.
Nevertheless, please refer to this official download portal as you proceed. It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.
From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. After installing the OS package to your PC, please remeber to delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
You may also need the use of these tricks:
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
Good luck and let us know!
