My Galaxy Nexus will not factory reset. I tried to flash many images. I deleted the gallery contacts, but it restores to a restore point on each reboot.
Currently, it is having "yakju-jzo54k". I am getting an OTA update. After downloading and updating, it is going to recovery mode with red caution sign. Then, it reboots after sometime. Again, a restore point is restored (with my old pics and contacts).
I tried Wug's Nexus toolkit, flashing it with a rooted boot.img, and deleting many files. Still, the old backup was still restored.
It's became a big headache now. So, any help is appreciated.
