M365 esc stuck

[Boss_vyc]

Hi

Can someone help with this problem?
I have m365 scooter with display from pro version. It was working good until I tried new custom firmware. Now is not displaying battery capacity and can't be turned off. The esc is completely stuck somehow. Tried to flash esc with stlink but always I get the "error bin not found" on m365rec software. Also the green led from esc is not turning on when is connected on stlink. Only red light.

Thank you
