In cases like this what will help is a fresh CV file (~140 kB in size; CV file is not Sound file 10-20 MB in size), which you can request from the manufacturer for free. Resetting CV8=8 in the ESU decoder doesn't restore all problems with incorrect programming.

Usually bricked decoders don't work and can't be programmed. You do need to cycle the power after a reset.

Also check the settings on CVs 31 and 32. You need to verify the correct settings with a manual from Bowser or the Loksound5DCC manual.

I'm not at all familiar with the MRC tech 6. Did you happen to put a value in CV 15 or 16 by chance?

I had just recieved a Bowser M630 with Lok V5. I switched the horn CV's and cycled through all 14 options. After a misclick on my MRC tech 6, the CV's refuse to change, but everything functions normally. Resetting the decoder hasnt worked either, is the issue in the controller or the engine?
