GMRS-PRO Firmware Changelog

This page lists official GMRS-PRO radio firmware releases in reverse chronological order.

Update tip: After flashing, if the screen does not power back on, power off → hold OK (top-left green key) → power on to initialize the new firmware.

Best practice: After major updates, back up your channels, then perform a Factory Reset and re-sync using the BTECH GMRS Programmer app.
