I'm on the verge of crying now. I upgraded my acer tablet 2-3 months back to ICS and it worked smoothly until recently when I was using an app. All of a sudden, that app became non-responsive. I tried to restart my tab and there it was- frozen with the acer logo. The tablet is completely frozen showing the acer logo. I have been searching for solutions in all other blogs and forums including this one. I have tried the reset button with a clip but no luck..!! I also have cleared the cache and everything by holding the power and volume. I have also tired to go for fastboot by holding power and volume up but it remains frozen as well showing- "starting bootloader from USB". I also copied the ICS update.img to SD card and mounting it. The tab tried to mount it but eventually the tab shows an android dummy with a red exclamation mark on its back. It means that there is a problem inside the system. Can anyone help me with this..?? What should I do now? I just want it working no matter what. I would be really grateful.
