[BUG] (Android) Unable to flash the latest firmware onto Buds3 Pro

[rafael-menon]

Describe the bug
A "Failed to verify firmware" error occurs when attempting to flash firmware version R630XXU0AYJ1 onto the Galaxy Buds3 Pro. The error message is: "You are attempting to flash a firmware for the Galaxy Buds3 onto your Galaxy Buds3 Pro. This can permanently brick your earbuds.". This issue persists regardless of whether the file is downloaded in-app or manually from GitHub.

To Reproduce
Steps to reproduce the behavior: Ensure the current firmware is R630XXU0AYG3 (Note: exact starting version may not be strictly required). Attempt to flash the update to version R630XXU0AYJ1.

Expected behavior
The firmware file should be verified successfully as a Buds3 Pro file, and the flashing process should begin.

Additional context
Latest app version, Samsung Galaxy S23 running Android 15 / One UI 7.

The currently installed firmware (R630XXU0AYG3) was flashed using the file from GitHub. Since applying that update manually, the official Galaxy Wearable app is unable to detect the subsequent version.

Man, do you have the ayg3 binary file? if yes, can you send it to me?
if you on the ayg3 js try to update from samsungs official buds manager

Exact same issue for me. Official updater says "up to date" even with ollllld firmware...along with this app saying the firmware is a mismatch (tried ayg2 and randomly axi1)

You can get the file here: https://github.com/timschneeb/galaxy-buds-firmware-archive#galaxy-buds-firmware-archive

I'm unable to update from the official app.

Same thing happening to me. I downgraded and wasn't able to go back using the normal app or GalaxyBudsClient

[oldsokkett]

have R630XXU0AYG3 on buds 3 pro, can't update to any version, not only to R630XXU0AYJ1, used only GalaxyBudsClient for Mac

Same for me, i cant back to latest. Is there a way to force update?

[NarwanyZiomus]

v4.5.3 Pre-release
and flash it using file from archive. Select buds 2 pro while manual connection setup.

:D i knew it goin to take 20m to figure it out

[Bananz0]

Suspected this would work cause that's the last version that doesn't check the version number before updating but was too scared to try it on mine. Omw trying it right now

After 400 disconnects and failures I was able to get the AYJ1 firmware to copy in 4.5.3. BUT...it still says AYG2 firmware and won't update through official app still (nor the unofficial) RIP buds
