Put your radio in flash mode first

1. Make sure the radio is connected to your computer via USB.
2. Turn the radio off.
3. Hold PTT + SK1 (the two side buttons) simultaneously.
4. While holding both buttons, turn the radio on.
5. The LED will flash red/green — that confirms the radio is in DFU mode.

Recommended before your first flash

This reads your radio's current firmware over USB and saves it as a .bin file. If you ever need to restore the original firmware, you can flash this backup straight back using this tool.

What is a donor file?

ClearDMR uses a vocoder — the audio codec that encodes and decodes DMR voice. Due to licensing restrictions, this codec cannot be bundled with ClearDMR. Instead, the flasher extracts it from your radio's original factory firmware, which you already own a license to use. The file never leaves your browser.
