F3 femento flashed with spracingf3 when it should have been EVO. Now board is locked in boot and btaflight cannot open serial port. Drivers are goodas i Can connect to identical board. Tried zadig and impulse rc neither could find the FC. Can this be fixed or is the FC toast. Thanks so much
Sounds like you need to reset the fuses. Can you contact the manufacturer and get the files to flash it? You will likely need to use the manufacturer software to get the software restored.
