About older iOS signing...
Well, here is the issue:
I attempted to update it to iOS 9.3.5 and it would not start downloading through settings. So I used iTunes to download it and it now gets stuck at 0% bar under apple logo.
the issue, iOS 9.3.4 (what it was using) is no longer signed by apple. Neither is iOS 9.3.5, which is the latest version it can run. I'm pretty sure that older than iOS 9.3.4 is not signed either.
Now, it is stuck in recovery mode and itunes cannot restore it.
