My Curve 9300 keeps rebooting all time (OS 6.0 Package 2391 v6.0.0.534)
I just leave the device unused for some minutes and then it restarts automatically (black screen with white status reboot line). That might happen upto 30 times a day. The device is brand new, battery is changed to a new one. Afterwards i can work with the BB fine for as long as I wish.

Any help is highly appreciated. Thank you.

You need to try another battery, as a test. Even though the battery appears to take a charge, it could still be beginning to fail, unable to deliver sufficient power under higher demand. Borrow a battery if you can.

It could also be bad or corrupt software. If you recently installed something, delete it and test. You may need to shotgun it: Do a security wipe and then add apps and themes back one at a time, testing in between. Worst case, you may need to wipe the device and then reload the OS.

Or, it could be a hardware problem. If you have wet the BlackBerry or dropped it hard, this would be suspicion #1. If you have exposed the device to moisture, even something such as a sweaty pocket, you should remove the battery dry the device well. (See blackberryfaq.com)

I had this same issue awhile back and it tormented me to no end. I tried quite a few suggestions I read on numerous forums until I came across one possible fix that I still have yet to see anywhere else. Do you know if your bb has the Memory Cleaner app enabled? Its a feature included out of the box so its on every phone (at least 9330 Curves like mine I know for sure). For some reason when its enabled it sometimes causes the device to reboot randomly. You can find it in your Options, scroll to Security, then to Advanced Security Settings, then to Memory Cleaning. From there you'll see the option to enable/disable it.

I also Have same issue with ChloeSky, this is couse of a software not uninstall properly.
The solution is :
- swipe out the firmware
- re install the firmware with BB desktop

if you have problem with re install with firmware you can ask BB local support to do it
hope this help
