That was the unintended bug introduced in 2.3.2, which is also still present in 2.3.4. The device is looking for a key to be present in the developer slot. Most users do not have this present, causing the freeze.
Well. My Passport2 is still on 2.3.2 and I want to update it to 2.3.5. What exactly should I do to avoid any freezing? I mean how to add that developer pubkey into developer slot if I prefer to update via relevant firmware file downloaded to my miroSD card?
I don't like to use Envoy for update purpose.
