Manual firmware downloads and downloading from the firmware history feature have been disabled for now. Samsung changed something on the backend and always serves the latest available firmware, no matter which is requested.

If you know a workaround, please follow up on this issue.

This is yet another firmware downloader for Samsung devices, but it has some special features.

For one, it's cross-platform. Bifrost runs on Windows, Linux, macOS, and even Android!

Bifrost is also a graphical program, with a shared UI across all supported platforms.

Most of the functionality in Bifrost is based on Samloader. The Python code has been converted to Kotlin and tweaked to take advantage of some of Kotlin's features.

Bifrost uses Jetpack Compose, JetBrains Compose for Desktop, and Kotlin Multiplatform to create a shared codebase for all supported platforms.

Binaries are available for 64-bit versions Windows, Linux, macOS, and Android. JetBrains Compose can't currently build for 32-bit operating systems.

Check out the Releases page for the downloads.

Release notes are available in CHANGELOG.md.

These errors are on Samsung's end. If you can, try using a different region/CSC.

These errors are on Samsung's end. Samsung may no longer be serving firmware for your device or may not have started serving firmware yet. Try a different region/CSC if possible and check to make sure your model number is correct.

On certain GPUs, Jetpack Compose/Skia has trouble rendering. Try running the program as an administrator.

If you have switchable graphics, try using a different GPU.

Samsung's servers sometimes throttle downloads to about 3MiB/s. For older devices, you may see even slower speeds. Different regions/CSCs may have faster downloads.

On your device, do the following:

1. Open the Settings app.
2. Scroll down to "About phone" or "About tablet" and tap it.
3. Tap "Software information".
4. Scroll down to "Service provider software version".
5. You'll see something like "XAA/XAA,XAA/XAU/TMB" or "XAR/XAR/" on the second line.

The first three letters there are your current CSC. The last three letters are the original/firmware CSC of your device.
Using the above examples, the first has a current CSC of XAA and a firmware CSC of TMB. The second has a current CSC of XAR and a firmware CSC of XAR.

Use the CSC picker dialog (the button that looks like a list inside the "Region" text field).
You can search for your country or region in there and see the different CSCs used. If there are specific carriers associated with a CSC, they'll also be shown.

Certain antivirus programs may flag Bifrost as malware. This is (hopefully obviously) a false positive.

There's a trojan horse malware family named Bifrost, which is part of the greater Bifrose family.
Antivirus programs flagging Bifrost (this app) seem to be doing it solely based on this app having the same name as the malware.

Bifrost (the malware) only affects Windows systems and has limited functionality after Windows XP. For more information, see this Wikipedia article.

Bifrost (this app) does not contain malware. You can verify this by browsing through the source code or by compiling it yourself using the instructions below.

Building this project should be fairly easy.

1. Make sure you have the latest Android Studio Canary installed.
2. Clone this project into Android Studio and let it import.

Bifrost makes use of Conveyor to create binaries for different desktop platforms.

Conveyor can build for Windows and Linux from any host OS, but macOS is required to build for macOS.

1. To build, first download and install Conveyor from the link above.
2. Next, open a terminal to the project's root directory.
3. Run ./gradlew :desktop:build (.\gradlew.bat :desktop:build on Windows).
4. Run the following command based on your target system.
   4.1. Windows: conveyor make windows-zip.
   4.2. Debian: conveyor make debian-package.
   4.3. Linux: conveyor make linux-tarball.
   4.4. Intel Macs: conveyor -Kapp.machines=mac.amd64 make unnotarized-mac-zip.
   4.5. Apple Silicon Macs: conveyor -Kapp.machines=mac.arm64 make unnotarized-mac-zip.
5. Check the output folder in the root of the project for the binary.

1. Open the Terminal view in Android Studio (bottom-left).
2. Enter gradlew :android:build on Windows or ./gradlew :android:build on macOS and Linux.
3. Once it finishes building, go to android/build/outputs/apk/debug and install android-debug.apk.

1. Open the Gradle view in Android Studio (top-right).
2. Expand the project, then expand "android".
3. Expand "Tasks," then "build," and double-click "build".
4. Once it finishes building, go to android/build/outputs/apk/debug and install android-debug.apk.

Download Bifrost_Android_<VERSION>.apk and install it.

Download the .zip ending in windows-amd64.

Native ARM64 Windows builds aren't currently available.

• On Intel Macs, download the .zip ending in mac-amd64.
• On Apple Silicon Macs, download the .zip ending in mac-aarch64.

• On Debian-based systems, download the .deb file.
• On other Linux distros, download the .tar.gz file.

On x64 Linux, download the amd64 variant. On ARM64 Linux, choose aarch64.

Translations aren't currently supported. Multiplatform resources make this tricky.

I'm hoping to have a translation platform ready soon.
