Boot to TWRP recovery
Tap on "Advanced"
Tap on "Terminal"
Tap "Select" - bottom right corner to change from browser to command entry
Enter 1st command
After 1st command, wait.....(DON'T TOUCH!!)
Then enter 2nd command, wait.....
REBOOT!!
(Little cheat...delete "fota" and replace with "misc", easier than entering the whole command again)
