My M31 was broke because of the failed update from Samsung, I finally restored my mobile, here are the steps:


download Odin software.  URL : https://www.androidinfotech.com/download-odin-all-versions/

You will need version 3.14 only

download M31 firmware : https://www.sammobile.com/samsung/galaxy-m31/firmware/SM-M315F/INS/download/M315FXXU1ATB7/321291/   (approx 4 gb)

 

Extract files from firmware, you will get 5 files, AP, BL , CP, CSC and Home_CSC

open Odin and connect your phone with pc, it will show you message of Added in left column.

 

in right column, browse AP, BL , CP and Home_CSC. (If you dont want your previous data, select CSC file or if you want to keep app and Data as previous, select HOME_CSC)

Then click on start, it will show you message of PASS, if everything works good.

Mobile should be 50% charged.

For any help contact me. Thanks

Try following link. It worked for me.

Just Charge your phone for 30 min (if it is fully discharged).

Download ODIN software.

Install/Run it on your PC.

Download latest firmware.

Unzip the file. No need to put in specific folder.

Connect Phone via USB/Type-C cable to PC.

Follow instruction mentioned in 3rd Method.
