Background

This firmware is an internal NonUI version of iOS 11.0. It has been seen on various iPhone 8 prototype units. Similarly to other recent builds, this one has a rather large filesize - a dump of its filesystem is around 9.1 GB.

Interestingly, this build contains kernels for Apple A7 to A11 processors, including differfent processor varieties. This has previously not been the case since iOS version 7.0. It also appears to support an unreleased processor type known as t8020. Based on previous NonUI firmwares having support for as of then unreleased processors - it's safe to assume that this processor is most likely the Apple A12 or A11X.
