I have the asus transformer TF101 which was already rooted with PRIME ROM when I got it. I absolutely love everything about the tablet but I want to update the firmware to the new android 4.0 ICS, but there is no place in the settings to update. I read that I should be able to find the update by going into the settings, then in the about tablet screen there should be an update firmware button. I'm not sure if it's somewhere else or if I might have to unroot my tablet? I'm fairly new at this and I could really use some help.
