For me I just usually copy the payloads I download from github onto my BB while its in arming mode, I regularly check to see if there are any new payloads and download them. Having a tool that can do that for me would be amazing, hopefully it will happen. :)
Just encountered this problem as I tried to update it, I followed the directions perfectly. I don't know what went wrong I tried everything but nothing worked, it looks like to be stuck in a loop forever, hope we can either get a replacement or help. Good luck to everyone with the same problem.
