I forgot the passphrase I set and I am stuck at the lock screen. How to either reset the device or somehow bypass the lock screen.
Googling my problem, various places suggest turning it off and then volume up + power buttons to get to some menu in order to do hard reset. But all I get is the ubuntu logo (just the image) on a purple screen and nothing else - no menu. Waited for awhile - nothing happened. Then if i hold the power button again, it gets back to the normal booting process and gets to the lock screen again, asking for the password.
