I have a rooted nexus 10 that was running 4.4.4. I got the ota notification for 5.0 and went ahead and tried to install. After downloading, the tablet tried to install and failed. Now I'm stuck in a reboot loop with a dead android and exclamation point. Did I do the wrong thing? Was I notsupposed to use the OTA update? Am I screwed? Any help would be appreciated.
