MCU unable to connect

I was mounting a spring to get strength to the umbilical cord, it was just a small part to understand how better it was getting.
But I endup assemble it all, and when I was getting close to the toodhead, the fans turn on.
I turn off the printer and when I turn it on I got the "MCU 'TOOLBOARD T1' unable to connect" error (first picture error on the touchscreen).
I search for any disconnect cable (as happened in past) but I couldn't find any. I turn a few off and connect it again.
Then I got a different error "MCU 'MCU' unable to connect" (second picture error on the touchscreen), and it stays like that.
Does anyone have any ideia what to look for?
Any disconnect cable/plug or a burned board?

definitely sounds like a wiring issue, just not sure if it caused permanent damage. Unplug/replug things and see if you can find any damage

Yes, have done it, but seems to be a damage toolboard.
Do you have any easy/fast idea to "deactivate" the T1 toolboad until i get a replacement, and "activate" it when i get it? (without getting to configure it all)
I might test it like that, to see if that's the problem, and not with the rpi.

Already got a new toolboard on the place.
Try to get a new configuration procedure but got stuck in this:

Already place the jumper, already reset it.
But no movement then...
What must I be doing wrong?
