I rooted but decided to go back to factory. I used bubby's one click to root an then used his s-on tool and the RUU method to return to factory settings. All went smoothly. And now my phone finally received the update notification so I switched to WiFi and downloaded it. Started installing it and when the phone reboots at the beginning of the install it just goes to a black screen. I let it sit for almost an hour and nothing changed so I did a battery pull and rebooted. Phone works perfectly but I cannot get it to complete the update. Always ends in a black screen and frozen phone. Any ideas?
