i have two a900's that i wanted to flash to cricket and one of them is flashed and everything works even the mms and wap but my other a900 doesnt want to activate for some reason....... this phone had a lot of things in it when i got it so master reset the phone(##678#) to factory to delete everything..... somehow this caused some files to change and now i cant activate it......did the master reset caused this????? is there anyway i can fix it?????
