    Default Disassembly Firmware Astro 320 to remove limitation radio

    It's possible to disassemble astro 320 firmware version 3.70 or 3.80 to remove lock with use to europe ???

    The garmin firmware version 3.60 insert the limit "Disabled dog tracking When used in developing countries for Which the radio frequencies are not authorized."

    Making a downgrade is possibbile version 3.40 last working in europe but unfortunately the new garmin collars TT5 and TT15 need the new firmware higher than 3.60.

    Many users are in the same situation, someone can give me some guidance on how to find the string in the firmware that implements the block radio frequency in the European territory by detecting the position.

    I even heard that grmn are making exchanges of the us astros and dcs to the eu versions if requested. I would check that first.
