Ok, I am a little rusty since I did root about a year ago. But, about 6 months later I needed service so I put the phone back to stock, and do rememeber that I placed the phone back to S-on. Anyway, fast forward to today. I have been using the phone fine since, but I have never been able to install system updates. The phone will download the update OTA or WIFI, and then when I choose to install it, the phone reboots and has the Android logo and the status bar. About 1/5th of the way into the update status the update fails, shows the esclamation mark, and is in a frozen state until I take out the battery and reboot. Any idea on next steps of what to check? I would like to just update to the latest. I am still on V2.2. Thanks for any troubleshooting ideas.
