Unique ID not valid
This is my first phone and i've been reading for a bit on how to unlock the bootloader, i recently upgraded to 4.5.141 and read that this worked to unlock it
I follow everything and then i get Failed to boot, from there i followed the onscreen instructions and then i get my unique ID and then i go on to step nine where you have to type in your unique ID once i put it in i get: <bootloader> Unique ID is not valid Aborting.
Then i press a key to continue and the phone reboots on the failed to boot 0x1000 and it repeats
Please Help Thanks
P.s. I have also tried pulling the battery and i still get the failed to boot screen
