Does a factory reset unroot the bionic out of 4ever root? How can I be 100% sure the SD CARD is wiped? Will future OTAs' install? I was 4ever rooted with the 5.5.893 OTA and performed the factory reset under privacy. (I checked "Erase internal storage media area" and "Erase SD card") I performed this operation and In settings / about phone it kept System version 5.5.893.XT875.Verizon.en.US superuser is gone! Thank you droid forum!
