tried this but my tablet 1838-25u says E:signature verification failed Installation aborted. What now?
I got the same response. How do i fix this?
I can't even get that far. I've tried rebooting into bootloader mode more than I can count but it always boots normally. There are only so many variations I can try of the instructions and I've tried them all numerous times. Any ideas? I found some sites which claim Lenovo locked out the ability to reboot into bootloader mode. Is this true?
