Bumibilis ba talaga ang phone pag naclean up mga unecessary files? Alam ko pati mga temp files from app cache like mga update files from online games dinidelete nito eh.
The link you posted shows that the trick is capable to unlink the apple id from the device firsthand not when its erased or lost. There is also this server trick thing called duolci before but I am not sure if it still work as of now.
