sorry super late reply, try mo wipe data sa recovery, para makapunta sa recovery hold mo yung vol.DOWN+Power button habang nakapatey, tapos pag lumabas na yung "BURST" screen, release mo na.
to navigate recovery:
vol.up to move up
vol.down to move down
power button to enter
WARNING: mawawala lahat ng installed apps mo, contacts, mms pag nag wipe data ka kaya magbackup ka muna ng contacts mo
