Things that you need:
A computer
A Samsung USB cable or the one that came with the phone
Stock firmware for your Samsung Galaxy S6 Edge (SM-G920P)
Odin3_v3.10.6 software
USB driver of Samsung Galaxy S6 Edge
Boot the phone in Download mode by doing the following steps:
Turn off the phone.
Press and hold Volume Down, Home, and Power buttons at the same time.
Once you receive the “Warning” prompt, press the Volume Up button to proceed.
Once you see the Downloading screen, plug in your phone via the USB cable to your PC. By this time, we are assuming that you have already installed to the computer the official Samsung driver for your Galaxy S6.
Download Odin and the correct stock firmware to your computer.
On your computer, unzip the firmware file you have downloaded.
After that, unzip Odin file and open the application.
Click on the blue box icon for Odin3_v3.10.6.
In Odin, click a button that says “AP” and select the file you unzipped earlier with a filename ending in “.md5”. This may take some time so just wait until Odin is finished.
Once done, click on the “Start” option and wait until everything is finished. The entire process may take up to 15 minutes so be patient.
You will be notified if you have successfully flashed the stock firmware by the word “PASS” in Odin. This means that the phone is now back to its original carrier firmware. Finish the process by rebooting the phone in recovery mode. Here’s how:
Turn off the phone.
Press and hold Volume Up, Home, and Power button at the same time.
Once you are in the blue recovery screen, use the Volume button to highlight wipe data/factory reset and the Power button to select it.
After that, do the same thing for Yes — delete all user data and wipe cache partition.
Finally, select reboot system now and wait for the phone to properly boot up. Reboot may take up to 10 minutes.
Flashing to stock firmware, if successful, won’t void the warranty of your device so if you want to eventually ask for a replacement, you can safely do so.
