AN IMPORTANT advise to note 2 usc users
If you are on mb1 despite suggestions and everything is ok with the lte sim then
Never ever try to flash cm or aosp based roms, they will render you phone with unactivated status as and when you will revert to stock or stock based roms and may be right away too, hence the phone will keep dialing *228 and 3g or 1x will be gone despite all parameters.
The issue is this generally leaves your lte sim which is actually supporting your data totally useless.
You will have to use a new sim no matter what.
The issues seems to affect the artificial min number on your sim card.
The best bet is never to flash mb1 radio, no matter what, I know mb1 gives a hint better data speed but STAY AWAY FROM MB1 RADIO, NO ISSUE IN FLASHING THE MB1 ROM WITHOUT RADIO THOUGH.
YOU HAVE BEEN WARNED.
