AWA5 firmware works fine. Will upload screenshots later today |

Maybe not really relevant but since this whole operation is quite risky and here isn't a lot of information around I just wanted to report that i was able to downgrade from As a sidenote, attempting to downgrade the firmware on Linux seems to fail when the firmware upload/copy progress reaches 50% with the error "Failed to upload firmware, Time out while waiting for the transfer process to finish" Unfortunately i don't have the logs for this and i'm not going to try it again so opening another issue for these failed uploads wouldn't make much sense(?)

I obtained the .bin from the same post on reddit. My galaxy buds 2 pro's I
bought from samsung on November 28, 2023. I am based in the US so these
came by default with AWF4 firmware, through the country code XAR. The buds
were upgraded to the AWI2 firmware.
I downloaded version 4.5.1 of the buds manager program. Now I'm in the
process of downgrading to avk3 firmware. Which gives out a serial number of
0's on both earbuds.

So downgrading to this version without issues is actually somehow possible.
I obtained the .bin from here (reddit)
<https://www.reddit.com/r/galaxybuds/comments/18a0lfv/how_to_fix_samsung_galaxy_buds_2_pro_tuning_sound/>,
its sha256 is
32efc7143f1cc0ebcb374f74e00a453c82b5781b77cae3047464e79b84ef11cd.
I used version 4.5.1.0 on windows 10 with the alternative bluetooth
backend and an intel AC9560.
Various people seem to have your same issue in the above reddit link, not
sure if it depends from the buds' manifacturing date (and thus the firmware
they were released with), the region they were sold in or something else.
Good to know that updating to a later firmware "fixes it".
As a sidenote, attempting to downgrade the firmware on Linux seems to fail
when the firmware upload/copy progress reaches 50% with the error "Failed
to upload firmware, Time out while waiting for the transfer process to
finish"
The upload is also significantly slower in comparison to windows.
I used ArchLinux with version 4.5.4 of the manager, with two different
bluetooth adapters:
ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
ID 0bda:8771 Realtek Semiconductor Corp. Bluetooth Radio
Unfortunately i don't have the logs for this and i'm not going to try it
again so opening another issue for these failed uploads wouldn't make much
sense(?)
