Cannot load to Ledger Blue

[emilyofearth]

I'm trying to load one of the sample apps to a brand new Ledger Blue (Firmware: MCU 3.4-hw15, SE: 2.1.1). I've tried using both --targetId 0x31000002 and --targetId 0x31000004 and neither one works.

With 0x31000002, I get "Target ID does not support SCP V2", and with 0x31000004 I get "Invalid status 6484". Is there a different targetId I should be using? If so, where should I have found that information?

Some further info: checkGenuine fails with status 6484 using either target id. This device does pass the "genuine" check in Ledger Live.

more info: found @HardAgency 's fork of this repo[0] where there is a new target id mentioned, 0x31010004. Tried this one and it worked. I'm not sure where they discovered that, but it would be good if it were mentioned somewhere, and even better if it were actually the value that the blue-secure-sdk provided.
