FYI I've been at this for hours/days trying to work out which power class byte to change and tried a good few .bin files which all give me the 2FA4; which byte did you change for the power class?

This has been a massive learning curve for me!

EDIT:
It doesn't look like I can send you a PM to share my VIN
What's your original MSV70 ZB number?

Also, did the error pop up after you clear the error?

Have you flashed RSA delete first? Before you flash 0da you have to flash RSA delete first

The power class byte for MSV70 is 0x2191
