Have you tried asking Lorch?

They told me need to replace the T-MAPRO3 MB

Did you replace it? Or is it stupid money?

It stupid money. I’m trying to bring the functions back by messing with the firmware.

I’m really jealous of your model — it’s fully functional.

Actually, mine is a Tweco model which is a T300 with a few functions locked down.

Fingers crossed a pro shows up and fixes this for me.

Sorry for my late reply.

I’m very far away of a pro.

So let the pro comes across to fixing your issues.

Mapro is about 1300€ here.
Anyway I will not share any IP.
