I get the following errors while trying to download a dwl file:

EDIT: If it matters, this is what I get in the traces: “Except RTK 161”

I have tried redownloading the firmware, stopping the application and even erasing it. Any pointers on how to sort this out?

On a side note: I noticed that downloading dwl’s now takes much longer than it used to. I guess this is because after the latest updates DS performs more checks? If so, are these really necessary? Quite annoying
