Exclamation MK2 no root sim-unlock

i just did an OTA to MK2 from official stock MJA
i down graded modem to MDC
did the Simunlock.exe and rebooted phone and verified it did work wish a different sim and it showed the ICCID in about phone status
i then reflashed the MK2 firmware from these forums and the unlock is still valid
*#0011# works ok...
well its a lil buggy but it does work
##3424# works and ##768#
APN menu works by default

just wish there was a way to block sprint activation and sometimes system update (but it not going off because im current) without being root
easy to do if your root
