Whenever I try to go in and perform the update, the OTA file will download and then nothing. After the file download is complete, no installation is performed and the update screen just metions 'Restart is needed'. Reboot the phone and no dice, it just asks me to download again. What is going on here? Do I need to restore back before SG 6.0? Unroot? Need help. The OTA download seems to keep re-downloading in the background and is killing my battery life.
