[BUG] Can't downgrade Buds2 firmware

[salihefee]

Describe the bug
Using the program, I choose a past firmware version, flash it succesfully and then connect again. But after checking the system information, I see that the firmware is still on the latest version. I tried with a local firmware binary, multiple online firmwares (those listed on the program itself) and a second pair of Buds2. Even though the program says the flashing was succesful, the firmware does not appear to be downgraded.

To Reproduce
Flash a lower firmware version using the program.

Expected behavior
Seeing the firmware version I flashed in the system information tab.

Desktop (please complete the following information):

• OS: CachyOS Linux x86_64
• Kernel: Linux 6.12.7-2-cachyos
• DE: KDE Plasma 6.2.4 (Wayland)
• Application version: 5.1.1.0

Log files
I'm not sure where to find the log on linux, but i can provide it if you tell me in the comments.
