I have a Samsung Galaxy Nexus. I have installed CM11 a while ago, but for about a week it keeps rebooting too often; it stays on for about 10-15 seconds, and then reboots.

I haven't installed anything suspicious in it. I just noticed that I can't update it to the latest version; I don't know why.

So I tried few things to backup my phone and wipe it with fastboot; tried to update to newest version of CM11 from CWM, but without any luck. It even keeps rebooting if I am in CWM.

Can you guys point me in the right direction? Maybe I am missing something. I keep searching for solutions, but cannot find any idea about how I can backup it, or maybe repair the ROM. I just need the Contacts and Photos from the phone.

  • The things you can try are: run adb logcat and get some info if possible. Remove SIM and/or SD-card and try again. Boot into recovery, is there still an old version left you could flash?

  • @ott-- but how would OP try to use adb if the device keeps rebooting.The connection will break just every time, even CWM recovery reboots.

  • I haven't any old version left on device, but this would make device not boot at all, because CM doesn't have the possibility to downgrade.

  • @Denees Do you have any fastboot type ROM with firmware files in it. I suggest flashing everything except the userdata (Internal SD card). Or, may be try flashing a new recovery first (like TWRP) and see if it reboots in this recovery as well.

  • I'll try to install TWRP with Nexus Toolkit at home, now I'm on Linux. But what you mean "any fastboot ROM"?
