Hello,

First of all, note that flashing your phone can render it unusable if the PC or the phone were to turn off during the process. Therefore, make sure that both the phone and PC are fully charged (in the case of a laptop).

The method is quite simple:
  • Download the https://nerdschalk.com/download-galaxy-s7-usb-drivers/ to connect your Android phone.
  • Enable USB debugging mode in "Settings > Developer options > USB debugging"
  • Download https://odindownload.com/
  • Download the firmware corresponding to your mobile. Samsung firmwares can be downloaded from here: https://www.sammobile.com/.
  • In Odin, check "Auto Reboot" and "F. Reset time" (and only these boxes)
  • Click on AP and choose the firmware file
  • Put your phone in Download mode by simultaneously pressing Power+Home+Volume Down
  • Click on Start in Odin and wait a full 5 minutes without turning off or unplugging anything.


And there you go!
