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! @npub12ctj...c5ky should reimburse the cost of this wallet at the very least!

The ColdCard CLI works great for firmware updates, and other tasks. Note as well: microSD card max size is 32 gb Virtual disk max size is 1 mb and firmware updates are now a bit larger than that

Oh, so that’s why the virtual drive didn’t work either. Thanks. It’s on a remote computer with me having to tell the user to type in the commands, so it wasn’t convenient to use the CLI. We attempted to do so, but we ran out of time for that session. I’ll first try to upgrade it to another old firmware and only later to the new one. If that one fails, I’ll take control remotely and do it over terminal.

@Momo the coins are out, so the firmware update is optional now, and a mk4 that reads neither the card nor usb is a device to retire rather than repair. three people coordinating 3.6 btc off a suspect signer in one day is the part worth writing down.
