How to SAFELY flash a Samsung with ODIN without losing data. Step by Step Tutorial

If you need to flash the firmware on your Samsung phone, here’s how to do it through your PC. This is useful for scenarios where you need to fix a software issue with the phone.

Please do not try this if you’re not sure if you truly have a software problem or if you have very important data. Instead, consider sending it to us for Data Recovery.

In this case, we have a Samsung S24 Ultra that we flashed firmware S928U1UES4AYA1 into the phone & did not lose any data.

Earlier in the day, I had done a CPU, NAND, EEPROM transplant on this phone & found it was booting up to the Samsung logo, then Android logo & would stay there forever.

Sometimes I would get the home screen, but it would be frozen & then fall back to the Android logo.

Flashing the firmware like I show in this video solved the issue & was able to recover all the data.

First step to flashing any Samsung firmware is to find out what version it currently has.
You do that by putting the phone into Download Mode and click Volume UP

Then you connect to your PC & open SamKey Tool: https://www.gsmofficial.com/samkey-la...

Within the tool, click “Read Info D/L”

Find the “Model”, “Version” and “Carrier” values

And look it up on https://samfw.com/

Download the file that matches the version & carrier of your phone

Extract all those files.

Then use ODIN to flash the phone. Download that here: https://xdaforums.com/t/patched-odin-...

Load the AP, BL, CP and Home CSC files

IMPORTANT: Use the “Home_CSC…” file in the CSC field. 
If you don’t select that file, YOU WILL LOSE YOUR DATA

Then click Start & let it load.
