A charge-only cable cannot flash firmware. Example requires a USB-A host port. If your computer has only USB-C, use an appropriate USB-C data cable instead. Reuse the device’s included cable where possible; this is not a standalone power-supply recommendation. - Tool: Computer with Chrome or Edge. ## Compatibility and cautions - FM-1 only. Newer flash revisions had beta, untested support when the source was reviewed. - Check the selected seller variant and flash revision. New UC25HQ80 units are not equivalent to a tested older unit. Music Arms lists the actual FM-1; shipping outside Thailand and flash revision must be confirmed. A seller page does not verify third-party firmware compatibility. - Source-reviewed, not independently hardware-tested. Confirm the model, revision and recovery process before changing device software. ## Buy [Search Amazon (unverified)](https://www.amazon.com/s?k=M-VAVE+FM-1) — Search destination only; matching listing NOT verified Search fallback only.
