I’ve had to do not one but two factory restores on my tablet and I still need to manually faff with updating the firmware. I had to root it to solve a known issue in android ICS. When the JB update came available OTA, I couldn’t run the update because my tablet was rooted. The only way to do a stock restore was to flash the official ROM. That kinda sorta worked, but for some godforsaken reason, my lock screen disappeared and was replaced with a promo-type display. There were a few other weird behaviours as well, like the fact that some configuration settings would not stay put, no matter how many times you set them. Unacceptable. A full data wipe/restore did nothing to fix this either. So now I downloading yet another 1gb ROM to see if I can get my baby back into a usable state. Grrr.
