Ender 5 pro (classic) 4.2.7 sonic pad issue

Hiya everyone
Sorry this is my first post but I’m kind of not getting anywhere with creality .

Yes I’m another struggling with adding a sonic pad to my ender 5 and getting it too work
I now know that the issue is that the 4.2.2 mb and 4.2.7 mb are very slightly different and I need to alter the bin file (I think lol)
But that’s as much as I know.

If you need a classic mini restoring or a race engine building for one I’m ya man ,30+ yrs in the trade etc

Aged 50 now and I just can’t get me head round into what I need to do to get this printer working with the bloody sonic pad lol

If someone could help me out in simple terms I’d be so great full

I’ve read all the topics here regards the same issue ,but don’t understand it sorry for being old skool

Again I’d be very great full if someone could simplify this process for me
