Yamaha Preguntas frecuentes de los clientes

Sorry you're having trouble with this. After downloading the firmware, ensure it's the only file present on the USB drive. The drive should be formatted to FAT32, and the firmware should be in the root directory (not within any folders). Once you insert the drive, the Yamaha receiver should automatically recognize the firmware. If it still says "not found", double-check the firmware version and possibly redownload it. If after doing all this you continue experiencing issues, the unit might need a repair due to internal issues.
