Have a 2012 Nexus 7. Upgraded to 5.1.1 -big mistake!!. SLOW and SLOWER. In process too downgrade back to KITKAT 4.4.4.
Have toolkit and factory image for Kitkat. Trying to unlock the device so I can falsh back to KITKAT 444. When I input "fastboot oem unlock" nothing happens on the device (supposed to ask for an OK to unlock) and the PC's screen has message ....
HELP!
Anyone can give me way to unlock the device ?? Thank you in advance for any suggestions, etc.
