Just last week, Saurik advised the jailbreak community not
to hold its breath for an A12(X)-compatible Cydia Substrate, but that doesn’t
mean that team unc0ver
won’t release a full A12(X)-compatible jailbreak; in fact, the contrary appears
to be true.
In the absence of Cydia Substrate on A12(X) platforms and
with little or no indication that it’ll ever be updated to support them, hacker
and unc0ver lead developer Pwn20wnd embarked on a new challenge – one that
involves implementing
an improved Substitute for A12(X) handsets specifically while continuing to
use Cydia Substrate for tweak injection on pre-A12(X) devices.
The jailbreak community has been waiting in suspense ever
since, but Pwn20wnd shared an update
on Friday that seems mostly positive about the situation:
The main takeaways from Pwn20wnd’s status update include:
- He is actively working on unc0ver’s A12(X) support
- He is building a ‘future proof’ and ‘stable’ replacement for Cydia Substrate using Comex’s libsubstitute
- This project will take time, so patience is advised
- Don’t update your iOS firmware in the meantime (stay on the lowest-possible firmware to improve your odds of being able to jailbreak)
Contrary to popular belief, Pwn20wnd’s upcoming Substitute project will work alongside the Cydia package manager, which is open-source and currently being maintained by unc0ver co-developer Sam Bingner.
As you might come to expect, pre-A12(X) devices aren’t
impacted by the Cydia Substrate vs. Substitute dilemma because Saurik already
updated Cydia Substrate for those devices last year. That said, it’s
unlikely that Pwn20wnd will deviate from using Cydia Substrate on pre-A12(X)
devices, and so those who are already enjoying full jailbreaks will have little
to worry about.
It’s worth noting that the Electra Team’s Electra jailbreak already
uses a version of Substitute, and that it works alongside Cydia or Sileo (depending on the
user’s personal preference). The upcoming
Electra12 jailbreak, on the other hand, will only work with Sileo, as
CoolStar wants to stop supporting Cydia going forward.
Are you excited to see that Pwn20wnd is working on a
long-term solution for A12(X)-based unc0ver users? Or do you plan to switch to
Electra12? Discuss your thoughts in the comments section below.
