Blackberry 9790 keeps rebooting on its own

**jimmy_key** · 10-13-2012, 10:25 PM

I have had my 9790 for 11 months and about 1 month ago I updated the os to 7.1. After I did this I started to have this issue where it would start to reboot on its own, sometimes once a day, sometimes 5 or 6 times in a row and it would drain the battery. Also I noticed the battery level on the screen isn't reflective of what the battery level actually is, it would go from full to red in seconds. I would do a battery pull and it would be back to 80 or 85 percent. I bought a new genuine blackberry battery to see if that was the issue but still same problems. I wiped the device and re-installed the original os from desktop manager twice and the problem is still there, very frustrating, any one have the same issue and managed to fix it?

I too have been facing this problem. I've tried everything, new battery, tried pretty much every software update for the phone but I still
get the same reboot problems.

I can't even use this phone for a few hours and it's really annoying. Anyone who has a fix please help!

I swear I experience the same thing . 8 months into having my phone start experiencing these abnormal rebooting / recycling of power. one min batt shows full, next min shows total red/drained. And the company which I purchased the phone from B-mobile TSTT , Trinidad and Tobago only gave me a 6mth warranty. I sure they knew this phone had this hiccup from before. please help!!!!!!!!!

Experienced this one with mine but I traced the problem to a screenshot app (vScreenshot) and viber. My 9790 keeps draining and rebooting 5-8 times a day and I tried the battery trick (paper) but it still won't get better. I booted in safe mode (hold down back key while BB is booting) and AMAZINGLY, my battery lasted around 14 hours.

I removed apps I didn't use but it was still doing the same thing. Took me a while to reach the Vs in my apps list but once I got rid of these two, my 9790's back to being awesome. I now have all my apps back except for these and I get about 10-12 hours with EDGE/2G and WiFi daily. Not bad at all.

Hi, I also had the reboot problem, terrible! I bought the device on ebay second hand but with warranty (3 months old). Kept rebooting when the mobile network was on. Changed SIM card, not any better. I sent it in twice, and only after insisting and writing a long letter with details, I got it replaced by an official repair centre in Germany. The owner before must have had some (other?) problem before, because from him I got the repair address. I received a brand spanking new device, and thank God, it is working :-).

Ended up buying a new battery. A lot of threads about other blackberry phones addresses this same issue. According to them, the issue is resolved by replacing the battery. So I shelled out INR 2500 ($50) and bought a new OEM battery. *fingers crossed* Will update after at least three days of testing.

Even a new OEM battery did not help. I have sent my phone for warranty claim. *fingers crossed coz I doubt a water clog* :P

My device is coming back from the Blackberry centre tomorrow after the warranty claim. They said they have fixed everything. Also they have changed the touchscreen, since I had issues with it recognizing touch feedback without me touching it at all. I'm hoping that everything is fixed. Will update tomorrow after I get it in hand.

Hi there Ive had the similar issues on the 9790 but i tried this and it seems to be free from the random reboots (at least for the last 2 weeks.

1.Go into the event log ( ALT + LGLG )
2.Menu / Blackberry key, Scroll to and Clear log
3.Menu / Blackberry key, Scroll to Options
4.Uncheck all the listed check boxes and save
5.Battery pull

Hope it helps, best of luck.
