We did it!
After a long coordination involving three people, we successfully moved 3.6 BTC out of an ColdCard MK4 and into a secure wallet.
We're not completely done yet. We still need to update the firmware, except the wallet won't recognize firmware files from either microSD or USB. So the device itself appears to be defective on top of the recent firmware disaster!
Coinkite (nprofile…h23z) should reimburse the cost of this wallet at the very least!
