Galaxy S25 users report that Odin3 v3.14.1 and 3.14.4 are incompatible with Samsung’s latest flagship. The same issue was reported by the owners of the Galaxy A55, which was launched last year. The Samsung Galaxy A55 and S25 support the A/B partition scheme for seamless updates. Actually, you can flash the latest firmware on these Samsung phones if you choose the CSC binary in Odin v3.14.1 or 3.14.4. However, doing so will wipe your phone’s data. Users wishing to keep data after a firmware flash seem to be out of luck.

In this quick tutorial, I’ll describe the steps to flash firmware on the Samsung Galaxy S25, S25+, and S25 Ultra and preserve data using the latest Odin 3.14.4. We all know the difference between the CSC and Home CSC binaries. We choose the CSC binary in Odin for a clean installation and go with the Home CSC file if we want to flash firmware, but keep the device data and settings intact.

If you want to flash firmware on your Samsung Galaxy S25/S25+/S25 Ultra, you’d naturally select the Home CSC binary in Odin to save your data. However, if you do not add the PIT file and select the Re-partition option in Odin, the firmware installation will fail. Odin requires the correct PIT file to partition the device appropriately.
