If you followed the hardware steps in Part 3 or the serial terminal method in Part 5, your device should now be fully functional. Remember: a factory reset is a tool, not a failure. With the correct code—now fixed and documented—your Grundig GX3800 can serve you for years to come.

This forces the microcontroller to boot into a "fail-safe mode" where it ignores the corrupted checksum and resets the PRNG seed to 0xFFFF . At this point, the default code 0000 works.
