Help needed, posibly bricked VESCs

You can use an stlink v2 ($10-15 on Amazon) and manually flash the firmware file from github.

• Download the firmware from github
• Hook an ST-LINK v2 up to the SWD port. Only use the GND, DIO and CLK pins. Have the battery plugged in. If you cannot plug in to the battery, then use the 3.3v pin as well, but this is not the recommended method. I’ve killed a few 5v to 3.3v buck converters on other ESCs using this method.
• Plug the ST-LINK v2 into the PC
• Download the STM ST-LINK Utility
• Open and click Target → Connect.
• Click Target → Program & Verify
• Click Browse and load the .bin firmware file.
• Click Start.
• Wait 30 seconds then unplug the STLINK and the battery from the ESC. Plug in the ESC to the battery and connect through the normal USB port or bluetooth to configure with the VESC tool or VESC app.

It looks like the Trampa VESC 6/75 firmware was added after the 5.3 release, so download the beta VESC tool from the VESC project site and use this file with the stlink

Once you upload the firmware with the stlink and restart the ESCs, and you are able to connect with the VESC tool, make sure to flash the bootloader in the VESC tool as well.
