Compatible with iOS 8 and 9 only, for now. iOS 7 not yet supported.
Tested and working on iPhone 4s, 5, 5s, 5c, 6, 6 Plus, iPad Air 2 — but should (theoretically) work on everything else, too.
safestrat adds another layer of safety to your iOS device by enabling you to boot your device to a mode where only the SSHd (/usr/bin/sshd) is active.
To use it, hold down volume down at boot, and connect your iOS device to your computer. Then establish an usbmux tunnel to port 22 on your iOS device, and you can go in and make any necessary changes.
Afterwards, just run "killall sshd" to continue booting.
Note that this is an unofficial binary release — comex has not yet made any binary distributions of safestrat, so I forked it, compiled it, and stuck it into this package.
