How do I go about flashing the OEM software onto it? I tried via Odin but it fails. Got the firmware from sammobile.com as per shown link below. Some guidance is appreciated. Please and thank you.
Hi all – Just wondering is this something that is possible? I have an AT&T s21 ultra with a Verizon Sim card in it. It is an AT&T branded device but like I said unlocked and has a Verizon sim card in it.
