Well to be fair TBTFlash.exe asked for the custom firmware, so I simply uploaded the modified firmware and it flashed the fw. Don't know if anything else is requiredHello, can you please describe how you flashed the Thunderbolt firmware? We need to use an external CH341a SPI flash ROM reader/writer. I believe TBTFlash.exe is a Windows application, but that app cannot flash a modified firmware.
