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;
