Thanks very much Vrata!
I managed to run the script from your 1st link and I’ve flashed it. I’m not sure if that’s disabled and neutralised the ME as I’ve run the diagnostic script and the output looks different from what Mladen said should occur here so I’ve posed the question there if you were interested.
Also, I’ll be digging into the 2nd link over the next few days, so I may have questions
