Background
This firmware is an internal NonUI build of iOS 11.0. While a seemingly earlier version of TigrisAni 15A93261h, this firmware is one of the first to be seen running on an iPhone X prototype. It is also not too well optimized for the phone's new screen, notch, and rounded corners, with parts of the screen being cut off towards the edges.
