I have a Lenovo A1000 tablet which is two years old. It just gave a notice that it needed a firmware update. It warned to be sure not to run out of battery (I have it plugged in) and that it would likely take 30 minutes to do it. I clicked to do it and the tablet switched off, then rebooted to a black screen with 4 lines of text at the top. two of the lines are highlighted in blue and the last two are not. They are as follows: HQ factory mode (in blue) Full Test (in blue) PCBA test (just white text) HQ item test (just white text) The tablet has been sitting like that for about an hour with nothing obvious happening. Any ideas what is going on? Should I just let it sit some more? Should I try to reboot it?
