Solution for bricked M31 devices.

[Sciphile]

It seems that the recent software update broke all M31 devices. As of now there is no official statement from Samsung regarding what should be done. 

You people can't go the the service centre due to the ongoing lockdown.

People who have a computer or laptop can fix the issue for time being by rolling back to a previous version of the software.

Just visit this Sammobile page and download the Firmware for February 

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

Download the firmware and install it on your smartphone using ODIN, Instructions are available on the Right hand side of the page itself.

Hope this helps you until Samsung provides a fix for this issue.

Does this solution fix the problem without loss of data?

I did fix this by flashingin above said method. downloaded time was about 4hours. I have 50mbps internet, but downloads at 2-3mbps only. Downloading is only tough job, flashing will be easy if u follow step by step. only two things. have samsung drivers in computer then good with Odin.

Well, I am not able to download the firmware even after creating a free account it takes me to the subscription page every time.

Sadly all these sites require subscription or a premium account if you want high speed download. You can check if there are other sources available
