I was flashing a ROM yesterday and when in recovery (188.8.131.52) on I went to choose "reboot system now" and the screen went black. I clicked the power button again and the screen the "home" screen came back in recovery and there was a message saying "back button disabled." After going through the same process of clicking the power button to select reboot system and the screen going black, the screen reappeared with another power button click and then a message saying "back button enabled." Anyone had this before? I've been flashing kernels today and the problem didn't return.
