I havent had luck with this program, the select devices I have tried, I receive the response that the IOS version is too old to be upgraded/downgraded which is utter stupidity because they have all been iOS 9-12 beta. I tried letting it update, usually being blocked by littlesnitch but results did not change.
It calls; tenorshare, hockeyapp, ip-api (by domain) & linode (by ip4) - all for unknown reasons (I have not done a pcap)

Continuing my amateur inspection I found its internal firmware list had a very select few & seemingly sporadic versions of Ios for each idevice - some only listing out of date betas...

Guess the reason why I am posting here is to ask; Am I the only one trying to manually update "/iAnyGo.app/Contents/Resources/firmware_list.json"?
I have started adding some of the older versions details I wish to downgrade to but do not have all the specs for current versions and was hoping someone else might be able to share their experiences so I could get an idea of whether or not i am taking the correct approach but am not holding out much hope unless i take the time to setup my own pseudo-signing server.
