RuntimeError: read fail

[fossie08]

Hi, thanks for the project.

I'm having an issue where the program exits after Check GPT, see logs below. I'm not sure if its helpful but the Echo dot that I'm using could never get past the second boot LEDs? I do have another echo dot that does boot properly, should I try the exploit on that one?

Once again thanks!

@fossie08 how did you solve this?

[fossie08]

Yeah, swapped over to Linux and it decided to work. Also I think I got this error with an Echo that didn't boot completely - stuck on the second blue ring on startup.
