I tried to root my Galaxy S7 and failed. Not only did I fail but in the process, I also installed the wrong firmware G930A (ATT) and did not take a backup.
I've been trying to revert back to stock but everytime I try with Odin, I either get a sha256 failed error or a Complete (Write) Error.
I've tried all the sprint firmwares from this site; http://www.theandroidsoul.com/download-galaxy-s7-firmware/#jump-model-no-sm-g930p-sprint None have worked.
I'm using Odin3 v3.12.3.
How can I revert back to the factory stock Sprint firmware for the Galaxy S7 (SM-G930P) after installing the wrong firmware?
