Hi there.

I'm in desperate need of help with my Nexus S. After updating CM it wont boot at all.

Earlier on, I've updated between 10.x releases using the CM Updater. I've done a backup using TWRP and then just clicked the latest stable and the phone has automatically updated, without any problems at all.

After much consideration I decided to go ahead and updated to the M6 version of CM11 for the Nexus S. This release was listed under "stable" releases (which is somewhat confusing, as it isn't a stable release?) in the CM Updater.

First I did a backup with TWRP and then I went ahead and selected the M6 release from the CM Updater. This is where I now know (via #cyanogenmod) that I did something wrong. I shouldn't have updated from a 10.x release to a 11.x release without wiping. However, there was no such information in the CM Updater and the release was listed under "Stable", so I never gave wiping a thought.

However, the phone reobooted and started updating, but displayed some errors that i didn't have time to write down.

Then it just rebooted and hung at the google logo. I waited for 15 minutes, and it was still just displaying the Google logo. So, I went into TWRP and restored the backup I did. after that the phone rebooted and it still hung at the Google logo. I pulled the battery again and went into TWRP and did a factory reset and tried rebooting. The phone hung at the Google logo again. This is when I did a factory reset AND restored my backup. STILL, the phone hangs at the Google logo.

What should I do? Is my trusted Nexus S gone forever?

2.Then Reboot recovery
3.Then restore ur TWRP Backup.(Make sure ur twrp backup is healthy )

If I may add, the M6 is a bit buggy, a more recent nightly is more stable.. or choose an M5, M4 or other snapshot if you prefer them..

Thanks! I wiped:
  • Cache
  • Dalvik Cache
  • System
  • Android Secure

The only thing I left out was External Storage. Then I restored my backup. After rebooting the phone hangs at the Google logo, once again. I wont get further than that.
