How To Restore To Stock Firmware

In this post, we’re going to show you a method to restore two of Samsung’s devices, the Galaxy Note 5 and the Galaxy S6 Edge to stock firmware.  In order to do so, we will be using Samsung’s flashtool, the Odin 3 to flash stock firmware.

Flashing a stock firmware reverts your device back to the way it was, removing any custom changes that you made by installing tweaks, ROMs or MODs.  Why would you want to return to stock firmware on your device?  Well sometimes flashing a stock firmware is the only way to fix your device.  If you’ve flashed a bad file or are in a bootloop, the easiest fix is to go back to stock firmware. Another reason to flash tock firmware is if you need to unroot a rooted device. These are the most common reasons for users to flash stock firmware.

Prepare your device:

1. This guide is only for use with all the variants of the Samsung Galaxy Note 5 and the S6 Edge Plus. If you use it with other devices, you could brick it.  To make sure you have the correct device, go to Settings>More/General>About Device or Settings>About Device.
2. Charge your battery to at least 60 percent. This is to prevent your device from running out of power before the flashing process is through.
3. Have an OEM cable that you can use to make the connection between your device and a PC.
4. Backup everything just to be safe. This includes SMS messages, contact, and call logs.
5. Backup important media content by copying the files to a PC or lapto
6. If you are rooted, create a backup EFS.
7. Turn on Samsung Kies, and any antivirus or firewall programs. These could interfere with Odin3 and the flashing process.
