Yesterday I've bought my first Nexus phone.

I've tried updating it to Android 5.0.1 through standard procedure (download -> update from Settings), but now it is booting (boot animation is playing) for 10 minutes already. Any idea what could that be and what should I do to the phone to get back to normal working Android?

On some phones it can take very long, even to half an hour, so try to wait a little more.

If that does not help you should try to do a factory reset and wipe /cache & /dalvik partition (from Recovery, if you have access to it). Usually this procedure would solve the issue: stuck on boot animation/reboot loops.

  • Correct me if I'm wrong, but wouldn't factory reset already be wiping /cache and /dalvik-cache?

  • I'm not totally sure. It usually depends on recovery, on mine device and recovery I know that I always had to manually format /dalvik, but not remember for /cache. Commented Jul 15, 2015 at 19:29
