Either connect to a laptop with the original USB cable or connect to an iPhone over Bluetooth.

Then upgrade the firmware over and over again until one of the attempts succeeds.

The stock firmware on those old devices are so badly broken. I've been there. This is the only thing that worked.

Once you've gotten the firmware upgraded it should work much more smoothly.

Thanks for the response. I was hoping to keep it air-gapped, but sounds like that may not be an option.

I can’t activate the blue tooth (which is currently disabled) since I can’t get off that screen.

I guess losing the airgap just to update might be fine, since my

purpose for the device is to calculate a 24th word checksum for a seed-rolling tutorial

Only the Jade Plus can maintain a true airgap. The original needs a hard connection (USB/BT) to upgrade firmware, and since the stock firmware is defective, you have little choice.

One option is to boot up Tails on a computer, install Green, then use that to upgrade Jade.

Ohh you’re right! I forgot I did have to connect it once before!
