Substitute is the preferred tweak injection method for the unc0ver jailbreak, but it can also be used by checkra1n jailbreak users who feel like using something other than Cydia Substrate.
Monday evening, Substitute received a quiet, yet important update to version 2.2.0 with what could only be described as notable changes.
If your jailbreak depends on Substitute as its primary form of code injection for jailbreak tweaks, which is likely the case if you use unc0ver and may be the case if you use checkra1n, then you might be excited to learn that there’s another brand new update available as of this Sunday.
Sam Bingner has launched an updated version of the Substitute tweak injection method this evening, officially bringing the package up to version 2.0.12.
Substitute is used by default on the unc0ver jailbreak when installing tweaks and add-ons and can be installed manually by the end user on the checkra1n jailbreak if Cydia Substrate isn’t already being used. But regardless of which jailbreak you use, this is an update you probably won’t want to miss.
Following the launch of checkra1n version 0.12.3, which added official support for A7 and A11 devices running iOS & iPadOS 14.5, Saurik was quick to update Cydia Substrate so that those devices could enjoy reliable tweak injection.
But Cydia Substrate isn’t the only tweak injection method that works on the checkra1n jailbreak. So too does Substitute, and users of this alternative will likely be looking for a similar update. Fortunately for those folks, said update is now available in the form of Substitute version 2.0.11.
The Sileo package manager has long carried the stigma of being exclusive to specific jailbreaks – namely those created by CoolStar-led development teams such as Chimera for iOS 12, Odyssey for iOS & iPadOS 13, and Taurine for iOS & iPadOS 14.
Third-party ports to permit Cydia and Sileo on the same device have always existed, such as the now legacy Diatrus installer and the more recent Bingner installer. The Oydssey Team even went as far as to create an Odysseyra1n script that could turn a checkra1n’d handset into a quasi-Odyssey device with the procursus bootstrap and the Sileo package manager; the latter was especially popular given the length of time it took for an inclusive iOS & iPadOS 14 jailbreak to surface.
Substitute, the tweak injection method used by the unc0ver jailbreak (and optionally on checkra1n devices), received an update this week that officially brought the package up to version 2.0.10.
Much like the previous update that launched around a month ago, Substitute version 2.0.10 brings bug fixes to improve the package’s performance and stability.
When you jailbreak your iPhone or iPad with checkra1n or unc0ver, the tool automatically installs the tried-and-true Cydia package manager by default. What you decide to do or install from that point on is up to you, whether you choose to install Zebra, Installer, or even Sileo. That’s right… we said it.
Sileo has long been thought of as a proprietary package manager for CoolStar’s jailbreaks such as Chimera and Odyssey. But now that Sileo is officially open source, it’s likely that we’ll see a lot more happening with Sileo in the foreseeable future. One such example would be Sam Bingner's Sileo fork, which makes installing the Sileo package manager on unsupported jailbreaks incredibly easy.
Substitute, the tweak injection method used on the unc0ver jailbreak, and sometimes even the checkra1n jailbreak depending on personal preference, received yet another update on Friday, this time bringing the package up to version 2.0.9.
The latest update comes just one day after Sam Bingner published Substitute v2.0.8 with preliminary support and speed improvements for unc0ver on iOS & iPadOS 14. Substitute v2.0.9 isn’t quite as substantial of an update as the previous version, but it’s still recommended for all current users.
The news officially broke early Thursday morning that unc0ver would receive an update with support for iOS & iPadOS 14.0-14.3 by way of a custom kernel exploit based on the recently released cicuta_verosa exploit by @ModernPwner.
With that in mind, it shouldn’t come as much of a surprise to unc0ver users that the jailbreak’s primary tweak injection method — Substitute — received a preliminary update this week to version 2.0.8.
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.
Sam Bingner of team unc0ver published yet another update for Substitute on Saturday, officially bringing the package up to version 2.0.6.
Substitute was only recently updated to version 2.0, touting notable performance and stability improvements for the tweak injection platform. Today’s update is just one of many released in the past week, with each of those gradually addressing bugs introduced by the latest version.
If you use the unc0ver jailbreak, then you might recall a Substitute update that was released just yesterday evening, bringing the tweak injection package up to version 2.0.4. It was just one of several updates to be released since Substitute received its major v2.0 rebranding shortly after the start of the new year, but it would be far from the last…
This Thursday evening, Substitute received yet another update. The package now sports the version number 2.0.5, however for the average jailbreaker, this update isn’t quite as imperative as yesterday’s would have been.
