After a brief hiatus from last month’s rush of Cydia Substrate updates, Saurik appears to be at it again. Starting this morning, checkra1n jailbreak users should be able to refresh their sources and see two notable new updates including Cydia Substrate version 0.9.7108 and Substrate Safe Mode version 0.9.6004.
Both packages are especially important for the checkra1n jailbreak, as one drives tweak injection while the other serves as the last line of defense between jailbreak tweak failures and the possibility of a consequential boot loop. Fortunately, these packages work in tandem to permit jailbreak tweak usage in a safe environment.
