CSL DD Firmware Motor 0

Bit of a long shot looking for any help or advice. Had some issues with this wheel base and not being seen by the computer. Made the error of forcing the bootloader to the latest firmware. Fixed the initial issue which turned out to be a faulty wire connecting the motherboard to the Quick release. But now I'm getting a motor firmware 0 issue. I'm very aware its me that's probably caused this via forcing the bootloader. So far I have tried rolling back firmware that was bundled with the drivers starting from 415 right through to 450 which hasn't solved the issue. Any thoughts or suggestions welcomed.
