SOLVED - Iconia A500 unroot - no way
Hi, I'm trying to unroot my iconia.
I've tried blackthunder unroot tool, seems to work but doesn't (as stated elsewhere).
So I'm trying to flash a stock firmware.
I downloaded the same firmware I have on the tablet:
renamed as update.zip, put it onto sd card, rebooted the tablet with vol down + power, the android appears, then falls down with a red triangle in.
So I've tried acer update decrypt, even if in the diagram was not contemplated, but I get an out of memory message.
Then I've tried to install a custom recovery, downloaded Acer Recovery Installer from the market, chose cwm, then when booting into recovery i get a red error message, recovery verified failed.
luckily the tablet still works, but I really need to unroot it, any help would be appreciated.
edit: I followed this:
and, with some issues, I think I was able to unlock the bootloader, in fact I could flash the stock rom.
many many thanks
