When doing diagnostic somehow the port setting changed latency from 1 to 16ms (16 does not work and give a lot of interuptions on readings) but I got it changed back to 1ms once I noticed it. This helped for some other modules but the FRM module was not possible to connect to again. I started reading up on this and caught this thread quickly. Do you think that a NFS Emergency flash could solve this problem? If so how do I know what address the module has and what the ZB number is? I think the ZB number is 9230450 (see attachments) but the address I don't know how to find.
If there is no point in doing this we have to order either a new part or a Xprog to continue I guess so I would love some feedback on that. I got a 45min drive there so if it's no point trying emergency flashing I'd rather get that xprog ordered and try it next weekend. Bad thing tho is that it rains bad here and the window is down and not to be controlled when the FRM is not responsive so the car can't be used.

NFS emergency flash won't work since the FRM is not communicating at all in this state. You'll need to order Xprog. The ZB number you listed is what was originally in your FRM, correct. However, the newest ZB is 9390490. I believe that this one has this bug fixed.
