I'm running stock rooted 4.2.2 MF3 with safetrap 3.65 with TWRP. I would like to upgrade to kitkat 4.4.2 completely stock rooted. Could someone please point me to the right direction for this. I don't want to mess up as I am on MF3 with safetrap and don't want to screw up my phone. Would it be possible to just unroot and update the phone with the at&t OTA update and then reroot?
