MD-380 – How to reset the PC programming password

It can happen that a “PC Programming Password”, set on the Tytera MD-380/Retevis RT-3 “CPS” programming software, is lost or forgotten. If that happens, there is no way to program the radio from your PC ever again.
However, there is a simple workaround:

  1. install the md380tools by Travis Goodspeed KK4VCZ; follow carefully his instructions for installation;
  2. issue the following commands:
    ./md380-dfu read mycodeplug.img
    printf '\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF' | dd conv=notrunc of=mycodeplug.img bs=1 seek=$((0x20a0))
    ./md380-dfu write mycodeplug.img
    
  3. when done, turn off the radio and back on again;
  4. your PC programming password is now empty;

I have a Radio TYT MD 2017, it was working fine and suddenly the keyboard buttons, the menu key, the side key 1, the side key 2, the side key 3, the key of P1, the key of P2 all stopped working , the Back button and the upper orange button, I request technical support to restore the original configuration of the radio TYT MD 2017. Due to the above, it does not allow me to access the functions of the menu, nor to any other function manually.
