big big thanks for support i will try to go to 1.10.90 and reportYour ESC #2 is either still at ESC FW v22.214.171.124, or you tried flashing it enough times that it is half-reprogrammed and dead.
- If it's still on ESC FW v126.96.36.199, you should downgrade to package firmware P3X_FW_V01.10.0090, as this is the version which expects that ESC firmware
- If it's dead, you would have to re-program the micro-controller directly, using STM programer. Or replace the whole ESC Center board.
Also, there is a reason ESC #2 failed so many upgrade attempts. The above is just fighting symptoms, not the problem.
The reason - UART connection from ESC#2 to FC is probably faulty. You need to find the hardware issue on the board and fix it. I suspect solder blobs are cracked around FC daughterboard, though the connection may be faulty somewhere else as well.
