I get as far as entering the commands then when i scroll down to apply update.zip and having to press enter in the command prompt with "adb push payload-update.zip /sdcard/update.zip"
I then get --Install from sdcard--
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Instillation aborted.
Any ideas??
I got it was hitting enter on the keyboard to quickly! Tip if anyone has this problem... use 1 hand... don't try and be fast by using 2 hands
