After a surprising announcement just hours after iOS 13.5 is released to the public, #unc0ver v5.0.0 has been released for support with iOS 11.0-13.5 and all devices including A12 and A13.

This update uses a 0-day kernel exploit from @Pwn20wnd himself. A 0-day exploit is an exploit that isn’t released until it is used to achieve something. In this instance, the exploit was not released until the jailbreak was released. This is the first 0-day exploit since iOS 8 in 2014. According to @Pwn20wnd, “Every other jailbreak released since iOS 9 used 1-day exploits that were either patched in the next beta version or the hardware.”

This update to the jailbreak was sponsored by case maker Phone Rebel by @EverythingApplePro. This is the first time a jailbreak has had a sponsorship. It means that jailbreaks may start making money for jailbreak developers without charging a cent to jailbreak users.

Occasionally we see Apple send phone specs (such as screen size, bezel size, etc) to case makers early, and if Phone Rebel is one, will they lose this right after this sponsorship? Probably.

On May 22, 2020 at 7:28pm, @sbinger tweeted that the Apple TV 4K on tvOS 13.5 will be jailbroken but not to expect it on the same release date.

Now that #unc0ver v5.0.0 has been released:

  1. Restore rootfs (root filesystem) with unc0ver v4.3.1.
  2. Update to iOS 13.5
    • I recommend restoring your device as new
  3. Install using AltStore/AltServer (Recommended) or any of the options presented in my “Stay up to date with the jailbreak community” article.

If you are interested in switching from #checkra1n to #unc0ver:

  1. With the #checkra1n app that installs with #checkra1n by clicking “Restore System” (aka restore root filesystem) in the middle of the app.
    • If you get an error stating “Restore Error: General”, you can fix it by rejailbreaking with #checkra1n with Safe Mode enabled.
  2. If not already on iOS 13.5 then update.
    1. I recommend restoring your device as new
  3. Install using AltStore/AltServer (Recommended) or any of the options presented in my “Stay up to date with the jailbreak community” article.

Please remember to sign and continue to resign with ReProvision as stated at the bottom of the article or you will not be able to rejailbreak if your device reboots for ANY reason.

Known issues with #unc0ver v5.0.0:

  1. [Very-Minor] Error with updating Substitute via Cydia.
    • Nothing to be alarmed about. Just an issue with how Cydia is handling the Substitute package. You already have 0.1.13 installed which is the most up-to-date version.
    • If you look at the install log you’ll see it’s trying to unpack com.ex.substitute (0.1.12) or (0.1.13).
    • Other package managers such as Zebra have no issues.
    • You can fix it by deleting cyinject.old in /usr/bin with Filza from BigBoss or TiGi Software.

This story will be updated once more information becomes available.
