Can't update HappyModel AIO X12 (ELRS + OpenVTX)

[LoakAudio]

Hi,
I'm trying to update my Happymodel AIO OpenVTX to OpenVTX 0.2.0 via the web page but I'm stuck on "Attempting to reboot into bootloader"

I tried with Chromium for linux as I know Firefox doesn't managed serial connection very well.

HappyModel AIO X12 (ELRS + OpenVTX), radio off.
Betaflight 4.4 RC4
Debian 10 last update

Tell me if you need additional information.

I am having the same issue with BetaFPV A03 VTx.

BetaFlight 4.4
Operating System = Ubuntu 22.04.2 LTS
Web Browser = Chrome

I have same problem as first time.
Make sure the SA protocol was detected by betaflight. Then try to flash again use OPENVTX configurator (make sure no other configurator software is opened)

Don't forget to power up the FC so VTX is on.
