You might get away not doing sbf in your situation, but for best results I would just do the sbf. 2nd-init roms do not contain a radio, so they don't change or touch your current one."kennyfool said:Question. If I am already on 2.2.1 but running Apex Rom, do I still need to SBF back? also, does flashing this or any other 2nd-init rom reflash the radio?
