MRC Sound Decoder not responding

I’m using a Digitrax Zephyr and have a Kato SD70 with a MRC Sound Decoder in it that was running fine until I tried to change the address of the loco. Using 03 it worked great. Now I tried to follow the steps to program it’s 4 digit address on the main using OPS Mode and messed up. So the I read the MRC instructions to reset the decoder to factory, this involves setting CV 125 to Value 1. I did this both on the main and program track and the engine will not run. I still get the basic engine sound coming out of the decoder but no horns, bell or lights and it doesn’t respond to throttle input.

Can someone please help?

In OPS mode, set CV 29=34 and you should be set.
