Windows computer needed

Latest Odin can Google it and download should be 3.13.1 or 3.14.1

Latest firmware from sammobile download , which carrier we might have here ?

You will extract files for Odin once download with 7zip and will do same for firmware with 7zip .

There will be 4 files after you extract the firmware
BL
AP
CP
CSC

Each of those files will go in Odin when you open to the corresponding slots
BL
AP
CP
CSC USE HOME CSC FIILE TO SAVE DATA
Home data slot dont put nothing



connect your phone with cable to computer , once the files are in its slots hit start, once done you'll see pass in Odin and it will reboot

I registered here just to thank you @mustang7757 !

I had this same problem, and these steps worked, I didn't lose any data. Phone is back like nothing happened.

Just for the record:
This problem appeared here after the monthly auto update, something must have gone wrong during the installation.

Thanks again!

Welcome to Android Central! What's the exact error message, and when does it appear?

 

[Rukbat]

A modem firmware flash would probably fix Abdul's problem with no loss of apps or data.
