Now that yalu102 has been out a while, along with its unstable predecessor for iOS 10.0-10.1.1, many of our readers will no doubt be running one of these two jailbreaks. As is always the case with a jailbreak on a new iOS version, many tweaks are not yet updated, and some can cause crashes or even bootloops.
It is consequently useful to be able to get into No Substrate Mode, to be able to escape tweak-related crashes and remove offending tweaks. The process has changed slightly since the days of the untethered jailbreak due to the fact that current semi-untethered tools do not boot into a jailbroken state. In this guide, we’ll show you how No Substrate Mode is accessed on the Yalu jailbreaks.
