    After I upgraded the firmware about a year ago to 18.03, I had no problem with unlocking the radio by depressing the P1 & P2 keys, and powering up the radio. It worked fine for about a year. The radio is locked again. I have updated the firmware to 18.11, and I still can’t get the radio to unlock.

    I have searched high and low for the software to unlock this radio, with no luck.
    Will someone please let me know where I can download this software?

    You need to Roll Back the firmware.

    You did make a backup before updating the firmware, Right ?

    Thanks for the reply. I know I can roll back to pre 18.03 firmware, but TYT is still providing updates to the firmware. I want to take advantage of updates as long as they continue to fix bugs or add new functionality. I know the free software is out there that will unlock this radio. But, I can’t seem to locate it. I’m confident someone will help me out. 73

    I think TYT had to lock the radios, Because of new FCC rules.

    To keep them from transmitting out of the band they are approved for .

    Why do you want yours unlocked ? What frequencies do you want to use ?

    I want to use the radio for the 2 meter and 70 cm Amateur radio bands.

    I have rolled the firmware back to 17.05;
    and the CPS to 1.06, with no luck.
    The radio still will not unlock.

    My TYT MD-UV390 is also blocked. Did you find a way to unlock?
