This post is only for M31 users who are facing boot stuck issue. This procedure will clean install firmware in phone and would make the device working again.

Things required- Computer>  Samsung USB drivers installed in it, Odin tool in PC,A working Samsung USB cable and Official Stock Firmware.

 

1)Firstly download M31 official stock firmware from the given link (This is the previous firmware of M31, so you won't face any issue in this firmware)-

https://www.sammobile.com/samsung/galaxy-m31/firmware/SM-M315F/INS/download/M315FXXU1ATB7/321291/

(Create a free account in sammobile.com and login, You can also pay for a premium membership if you want to increase download speeds)

2)Download Odin tool from same link from where you're  downloading firmware>Install Odin.

3)Extract the firmware files with an archive tool.>You should get 5 files: AP , BL , CP , CSC_ , HOME_CSC_

4)Add each file to its respective field in Odin.Note that if you want to keep your old data than add HOME_CSC_ file And if you want to do a clean install than add CSC_

(Don't mess with any other settings in Odin tool)

5)Boot phone to download mode-(I'm guessing that your phone is already in download mode so you don't need to make any changes in phone.)

7)Install Samsung USB drivers from this site on your PC-https://developer.samsung.com/mobile/android-usb-driver.html >Connect phone to PC.>Odin should detect your phone and a blue box will appear with COM port number in it.

8)Click Start button and wait for Odin to say 'PASS' in a GREEN box.>Your phone will take some time to fully boot after this procedure.

No,you won't face any problem with this method.Orignal stock firmware will be installed in your phone.

Just ignor the update after installing this firmware and wait for a stable update release.
