ok so i know the SACS thread is closed. i was reading on youtube that the reason that V4 was giving people (including me) network problems is because of the baseband. its saying to be on version N900PVPUCNC5. i checked and im on Version N9000PVPUCNAB. im just asking for a little help. i really like sacs. so is there any way to revert to N900PVPUCNC5 so i can make v4 work? any suggestions will help. thanks.
