Updated to Jellybean last night. Everything went fine. Downloading and installing firmware, updating apps, automatic restarts etc. But somewhere along the line, something went wrong. The OS never started up. the tab stayed on the: "ASUS inspiring innovation, persistent perfection" page, with revolving dots, and never finished starting up. first for 1½hours, then I rebooted, same thing, cold reboot, same thing. Even tried the reset pin hole thing. So now my infinity is stuck like this. I can't turn it off, if I press and hold the power, it just reboots, and hangs at the same place. Do you have any ideas? I'm starting to think that a factory reset is the only option from here (even though that will erase all my content). But how do you do that, when you can't get to the OS settings? Is there a thing to do during cold reboot? The Tab was unstable before the firmware update. Worked ok for a couple of hours, then started to freeze up, and eventually showing blank home screens, force closing the launcher, and eventually self rebooting. This happened 1-2 times a day before updating to JB. Help is much appreciated.
