Unc0ver jailbreak updated to v4.0.1 with bug fixes and improvements

It was only yesterday that Pwn20wnd released unc0ver v4.0.0 to the general public with official support for iOS 13.0-13.3 on A12(X)-A13 equipped devices. In doing so, unc0ver became the first public jailbreak to support A13 devices, and also the first public jailbreak to support iOS 13 on A12(X) devices. But that’s old news now.

On Sunday, Pwn20wnd released a small update for the unc0ver jailbreak, officially bringing it up to version 4.0.1. The hacker announced the latest update via Twitter earlier in the afternoon:

Jailbreak tweaks of the week: Appaze 2, Castmary, VolumeLock, and more…

With all the exciting developments happening in the jailbreak community lately, from checkra1n receiving Linux support to the unc0ver jailbreak being on the cusp of implementing A12X-A13 support on iOS 13.3, it’s never been a better time to be a jailbreaker.

In this roundup, we’ll discuss all the latest jailbreak tweaks released from Monday, February 10th to Sunday, February 16th. As usual, we’ll kick things off by talking about our favorite releases first and then wrap things up with an outline of the rest afterward.

Unc0ver v4.0.0 adds support for A12(X)-A13 devices on iOS 13.0-13.3

Those who’ve keenly waited for the unc0ver jailbreak to officially support A12-A13 devices running iOS 13.0-13.3 devices by way of Brandon Azad’s oob_timestamp tfp0 exploit will be happy to know that the wait is finally over.

In a Tweet shared just this afternoon, project lead developer Pwn20wnd launched unc0ver v4.0.0 with support for the aforementioned device types and firmware versions:

Configure Various system settings on a per-app basis with Appaze 2

If you’re anything like me, then you might use particular device settings in certain apps to get the most out of using said apps. For example, perhaps you use maximum brightness in YouTube and a lower brightness in Safari; alternatively you might use Rotation Lock in Safari, but not in YouTube.

Assuming the aforementioned behavior describes you in any capacity, you might want to turn your attention to a newly released jailbreak tweak called Appaze 2 by iOS developer AnthoPak. This tweak lets you configure system settings on a per-app basis to make using those apps as comfortable as possible.

Latest unc0ver build seeded to internal testers fixes bug that delayed public release

Pwn20wnd issued a build of the updated unc0ver jailbreak tool with support for Brandon Azad’s oob_timestamp tfp0 exploit on A12(X)-A13 running iOS 13.0-13.3 to internal beta testers earlier this week. While many anticipated a public beta launch shortly after all the positive comments shared by internal beta testers, a bug was later discovered that delayed any sort of public release.

Fortunately for those waiting to use the new unc0ver on their compatible device(s), patience is almost certainly a virtue. In a Tweet shared Friday evening by Pwn20wnd, we learn how the pesky bug that delayed the initial public release of the renewed unc0ver jailbreak tool had been resolved:

Critical bug fix for Substrate Safe Mode released for checkra1n and unc0ver users

If you’re using a modern jailbreak that uses Cydia Substrate as its primary means of tweak injection, be it checkra1n or unc0ver, then today might be a good time to fire up your preferred package manager and refresh your sources.

Substrate Safe Mode appears to have been updated to version 0.9.6003 with a critical bug fix. The checkra1n team shared the announcement in a Tweet delivered early Friday morning:

Planning to use unc0ver to pwn your iOS 13.0-13.3 A12(X)-A13 device? Get AltStore now

The unc0ver jailbreak is so close to publicly supporting iOS 13.0-13.3 on A12(X)-A13 that we can almost taste it. Support for Brandon Azad’s new oob_timestamp exploit was pushed into internal beta testing yesterday afternoon, and according to Pwn20wnd, unc0ver could be publicly available in the next 24 hours or so if everything goes smoothly.

Assuming you managed to downgrade to iOS 13.3 from iOS 13.3.1 before Apple stopped signing it yesterday or already had some version of iOS 13 installed between 13.0-13.3, you’re probably wondering what you can do to prepare your jailbreakable handset. If that’s the case, then we’d advise setting up AltStore on your Mac or PC.

Apple stops signing iOS 13.3 as updated unc0ver jailbreak nears public release

Apple must’ve caught wind about Pwn20wnd’s fast-paced progress on updated the unc0ver jailbreak for iOS 13.0-13.3. Not even a few hours after internal beta testers hyped the project on Twitter with the #unc0ver hashtag, Apple officially closed the signing window for iOS 13.3 to prevent downgrades from iOS 13.3.1.

Apple’s swift blow to iOS downgrading on Wednesday was somewhat out of character for the company because it transpired much earlier in the day than usual. While Apple regularly unsigns older firmware, the abruptness of iOS 13.3’s unsigning after Pwn20wnd’s slurry of announcements regarding unc0ver suggests that Apple intended to contain the jailbreak situation before it could reach the masses.

Unc0ver enters internal testing with support for A12(X)-A13 running iOS 13.0-13.3

Hot off the heels of a plethora of teasers that have been shared over the course of the past couple of weeks, Pwn20wnd has officially commenced an internal beta testing phase for the unc0ver jailbreak with iOS 13.0-13.3 support on A12(X)-A13 as of Wednesday afternoon – a feat made possible with Brandon Azad’s oob_timestamp tfp0 exploit.

The news surfaced by way of Pwn20wnd’s official Twitter account, which earlier this morning noted that unc0ver would soon move into the internal testing phase. A few short hours later, internal testing officially began:

Castmary gives your iPhone an iPad-like grid App Switcher

The App Switcher experience on the iPhone leaves a lot to be desired, especially if you’ve ever used an iPad before. That said, it’s mind-blowing that Apple hasn’t done anything about this yet.

If you’re tired of waiting for Apple to implement an official solution, then you can now take advantage of a new free jailbreak tweak called Castmary by iOS developer Simulation to get an iPad-style grid-based App Switcher on your iPhone or iPod touch.

Pwn20wnd prepares for internal beta testing as unc0ver for iOS 13 takes shape

There’s been a ton of hype recently regarding Pwn20wnd updating the unc0ver jailbreak with official support for iOS 13.0-13.3 on A12(X)-A13 devices as of late, a feat only possible with Brandon Azad’s new oob_timestamp tfp0 exploit. But just how far along has the tool’s development come? A good question, and presumably one that has already been answered.

According to a series of Tweets shared by Pwn20wnd Tuesday afternoon, it would seem that tweak injection has been updated to work flawlessly on A13 devices (it was already working on A12[X]):

Sileo port for checkra1n discontinued, future update could Frankenstein the checkra1n bootstrap

At the end of 2019, the Sileo Team launched a botched tool that could be used to port the Sileo package manager onto the bootrom exploit-based checkra1n jailbreak. The launch wasn’t as seamless as some would have hoped, lacking synergy with the official checkra1n installer app. Moreover, it uninstalled Cydia and checkra1n resources in place of Sileo and its own dependencies with seemingly no obvious way of reverting.

Those who’ve been following the progress of Sileo for checkra1n closely may have noticed a peculiar Tweet by way of the Sileo Team’s official Twitter account early Thursday morning:
