Here’s how to escape/fix the dreaded boot loop/respring loop/safe mode loop on the iOS 10 – 10.2 Yalu Jailbreak + How to troubleshoot and disable the tweaks causing re-jailbreak issues – NO RESTORE NECESSARY!
Since the iOS 10 Yalu jailbreak is semi-untethered, we can’t just reboot into safe mode to remove the last tweak we installed. We have to enter NO SUBSTRATE mode and then remove the tweak(s).
Note: If you installed Appsync, this won’t work for you. You’re screwed.
