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?

First of all download the stock firmware for your Samsung Galaxy S7(G930P - Sprint) from here. But you need to create an account on sammobile website for free by clicking on "Regular Download" button.

To Install the stock Firmware follow the steps below

  • Extract (unzip) the firmware file
  • Download Odin v3.11.1
  • Extract Odin ZIP file
  • Open Odin v3.11.1
  • Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
  • Connect phone and wait until you get a blue sign in Odin
  • Add the firmware file to AP / PDA
  • Make sure re-partition is NOT ticked
  • Click the start button, sit back and wait few minutes
