Samsung Galaxy S26+ a bootloop, a black screen, or a that won't get past the Samsung logo? Below you'll find every firmware build currently available for the device, a reliable download link, and a full Odin flashing guide you can actually follow start to finish.
Before you download: full firmware flashing via Odin wipes all data, so back everything up first. And always confirm the CSC/region code matches your device — using firmware from the wrong region can lead to problems after flashing.

How to Flash Samsung Galaxy S26+ Using Odin
- Download the firmware and extract the .zip fully to get the .tar/.tar.md5 file — Odin won't read a zipped folder.
- Install Odin and the Samsung USB driver from the links below, then open Odin.
- Power off the phone, then hold Volume Down + Volume Up and connect the USB cable to boot into Download Mode. Press Volume Up to confirm.
- Connect the phone to your PC using a good-quality USB cable — cheap cables are a common cause of connection drops mid-flash.
- In Odin, click "BL", "AP", "CP", and "CSC" and select the matching files extracted from the firmware package.
- Once the port shows as connected (blue/green "COM" box), hit "Start" and let it run — don't disconnect the phone during this step.
- The phone will reboot on its own once flashing finishes. First boot can take a few minutes longer than usual, so give it time.
Common Flashing Errors and How to Fix Them
"FAIL!" in Odin — usually a wrong CSC/region combination or a corrupted file. Re-download the firmware and confirm the CSC code matches your device.
Phone not detected in Odin — almost always a driver issue. Install the Samsung USB driver from the link below, then re-enter Download Mode and try again.
Stuck at "SW REV CHECK FAIL" — this means you're trying to downgrade the bootloader/binary version, which Samsung blocks by default. Flash a firmware with an equal or higher binary number instead.
Frequently Asked Questions
Is this firmware official?
Yes, these are unmodified stock builds.
Will flashing delete my data?
A full firmware flash (BL+AP+CP+CSC) wipes the device, so back up anything important first.
My model number doesn't match exactly — can I still use this?
Stick to the exact CSC/region code (INS) shown in the table above. Flashing firmware built for a different region can cause network or boot issues.
Tools You'll Need
Before flashing, make sure you have Odin and the correct Samsung USB driver installed on your PC — most flashing failures come down to a missing driver or an outdated Odin version rather than the firmware itself.
