My phone is rooted and running cm 10.2.1 but I need gps to actually work so I want to put the scock rom on , I tried locking the bootloader and using rru update but it always fails as it is an older version than is already on the phone , the hboot is 1.72.0000 and it is 188.8.131.52 and radio is 5.1204.167.31 , anyone know of a rru that will work ??? or another method of getting stock on it ???
