Substitute, the tweak injection and code substitution method that is commonly utilized by the unc0ver jailbreak, and in some cases even the checkra1n jailbreak, received a major revamp with the launch of v2.0 at the start of this year.

Over the last couple of weeks, Substitute has seen a slew of smaller updates comprising of bug fixes and performance improvements, and as it would seem, there are more planned updates in the pipeline.

Substitute v2.0.7 was just released late last night on Sam Bingner’s official repository, and according to the official change log, it brings the following changes:

Changes in Substitute 2.0.7 (1/19/2021)

Add a workaround to allow cycript to be injected to backboardd

It’s not a substantial update, but nevertheless, it’s recommended for all users as it ensures the best compatibility with all jailbreak packages, including cycript as of the latest version.

If you’re already using Substitute, then you can open your favorite package manager and refresh your sources to find the latest update. Those who aren’t already using Substitute would need to add Bingner’s repository if they haven’t already.

Please note that this doesn’t apply to the Chimera or Odyssey jailbreaks, as these depend on libhooker for tweak injection instead. Unc0ver users will find that Substitute is the default tweak injection method, while checkra1n users may choose between Cydia Substrate or Substitute at their leisure or alternatively run the Odysseyra1n script to enjoy libhooker and Sileo instead.
