Hey everyone,

I'm currently trying to fix the sleep issue some of you have and need testers who are having this issue and are willing to try out some stuff. First of all, I need to find out if the bug is caused by one of the kernel exploits or if it is caused by replacing analyticsd. ~~If you want to help, could you please try the following:~~ Update: Enough people tested this.

1. Install irecovery (brew install libirecovery)
2. Connect your iPhone to your Mac via USB and put the iPhone into recovery mode (From The iPhone Wiki: Press and quickly release the volume up button. Press and quickly release the volume down button. Then, press and hold the side button until you see the recovery mode screen.)
3. Run irecovery -s and enter the following commands:

• setenv boot-args no_untether
• saveenv
• reboot

This should disable the untether (you can test that by trying to run unc0ver, if it says unsupported or if the unc0ver Untether App crashes the untether is disabled). Please use your iPhone normally for about an hour or so and comment whether or not you still experience the sleep issue (please also include which iPhone and iOS version). To re-enable the untether, perform steps two and three again, but instead of entering setenv boot-args no_untether enter setenv boot-args x instead.

iPhone Xs iOS 14.3

The untether failed to install. Error:

I restored my rootfs using SnapBack since the fugu app got deleted. I was having some issues so I needed to restore the rootfs. Upon re-installing Fugu after this, I get "Fugu is already installed" after I click Jailbreak + untether, and unc0ver now says Unsupported again, so I'm basically stuck.

Seems like I'm not the only one having this issue. People on Reddit is having this exact error with this exact device on this exact iPadOS version.

The iPad Air 4th Gen has the same processor as the iPhone 12 Pro Max (A14 Bionic), and if it works on iPhone 12/Pro/Max, it technically should work on this iPad too.

Well, no. Not exactly. Attaching a picture below so you can see what's really happening:

14.3, SE2, ive roots numerous times, installed, reinstalled fugu & unc0ver, ive updated untether, everything & the app still doesnt show...i followed same process as i did when initially installed fugu, updating fugu after sleep bug & when 7.0.2 dropped (i didnt realise could update u0 without reinstalling fugu completely lol), ive even updated untether via fugu...(install fugu via mac, sideload unc0ver ipa)

everything installs without any errors & does what it should do....but still untether.app isnt showing...

any ideas??

Hi. Looked through trying to find a solution to this and I tried the ones that were up and they didn't work for me. I feel like the fix is extremely simple but i cant pin point what to do. Can anyone help with this.

I'm sorry for any inconvenience and thank you.

(I'm referring to: " cp: ../arm/iOS/Fugu14App/build/Build/Products/Release-iphoneos/Fugu14App.app: No such file or directory Failed to create IPAs! Exit status: 1 " at the bottom of the screenshot.)

Heres a clip of it...

Does it nearly everytime, the times it doesnt, it just opens to a black screen.

iPhone 12 Pro Max. 14.5. So I don't get texts on my number. I get green text but not blue. When I reboot to unjailbroken state. It works fine. I think this bug is from uncover. Not fugu14.

I have installed the app on a iPhone XS Max (iPhone11,6). I have compiled with jailbreakd successfully, however after I had pressed the "jailbreak + untether" button and rebooted, I tried connecting to the device via netcat on port 1337 and it fails to connect. My iOS version is 14.3. I had also been jailbroken with unc0ver on the latest version. I have not restored the root filesystem however.

So i get the error "The File Fugu14App.closure doesn't exist.

Here is a Screenshot of that. Any idea How to fix that? I have an Iphone 11 with IOS 14.3 AltStore 1.4.8 and tried to install Unc0ver 8.0.0

"

I get stuck on this black screen after I’m redirected the second time from AltStore https://user-images.githubusercontent.com/93642145/140023559-d63ef48e-1bc6-451d-8b52-80dc8fee7bc4.MP4

Hello I've recently installed uncover jailbreak and with the package fugi but it is crashing and I've goto re jail break device any help would be appreciated thanks

Hello. Sorry to disturb When will there be a port/revision of fugu 14 for ios 14.2 and will it be at all?

P.S. English isn't my first/native language, sorry for mistakes

Fix a race condition in GUI when printing.

And it seems the exploitation and post-exploitation work on my iPhone 12 iOS 14.2.1 without any modification.

Fix malfunctioning analyticsd daemon

While the patch in Fugu14 preserved the user id and $HOME by changing the name of the user _analyticsd to _nanalyticsd, it seems that some other daemon changes the owner of /private/var/db/analyticsd and its subdirectories to ·_analyticsd·, whose uid has changed to 264. This will cause the _analyticsd.back with uid 263 to not be able to read /private/var/db/analyticsd at all, with error: Home directory is not setup. Waiting to see if it gets repaired....
This fix is based on the following facts:

• dyld enables independent closure loading by checking the env $HOME is a subdirectory in /private/var/mobile/Containers/Data/.
• launchd sets the daemons' $HOME env via getpwname_r.
• analyticsd get its own working path via getuid and getpwuid.
• An unknown daemon will set the owner of /private/var/db/analyticsd to the user name _analyticsd.

So if the passwd and master.passwd have the following contents, things can be easily fixed.

passwd (master.passwd is similar)
_nanalyticsd:*:263:263:Analytics Daemon:/var/db/analyticsd:/usr/bin/false
_analyticsd:*:263:263:Haxx Daemon:/private/var/mobile/Containers/Data/Fugu14Untether:/usr/bin/false

And then, after the system is powered on:

• launchd launches /System/Library/LaunchDaemon/com.apple.analyticsd.plist with username _analyticsd and set $HOME to /private/var/mobile/Containers/Data/Fugu14Untether based on the username.
• Then the dyld will load the closure exploitation and the system will be jailbroken.
• The unknown daemon will set the user ID of /private/var/db/analyticsd to 263, based on the username _analyticsd.
• Then the analyticsd.back with the user name _nanalyticsd is launched, which will use the uid 263. Although there are two user with the same uid 263, it will only pick the first one by getpwuid. So it will use /private/var/db/analyticsd with the correct owner, uid 263

Then the battery detail in Settings works properly.

If you have jailbroken by Fugu14, you can try the manual steps below, or remove origin Fugu14 jailbreak modification then and use this PR to jailbreak. Restoring rootfs is a easy way, but loses all tweaks. Or manually undo all modification according "Jailbreak" section in Fugu14 writeup.

Fugu14 supports iOS/iPadOS 14.3-14.5.1 unmodified, and 14.2-14.2.1 by modifying the code. Is it possible to backport the Fugu14 untether to iOS 12.x and iOS/iPadOS 13.0-14.1 on arm64e devices, iOS 9.2-12.5.5 and iOS/iPadOS 13.0-14.1 on arm64 devices, and iOS 9.3.5-10.3.4 on arm32 devices? Also, is it possible for the untether to support tvOS 9.1-14.5?

(Crosspost from Issue #2293 pwn20wndstuff/Undecimus)

The Fugu14/unc0ver jailbreak evidently hijacks analyticsd, and renames the stock service to analyticsd.back, also editing /etc/passwd to make the analyticsd service use group _nanalytics instead of _analytics, which seems to be the root cause responsible for infamously breaking the Battery Usage settings history logs (BatteryLife/CurrentPowerLog.PLSQL, etc), as well as possibly the AirPlay speakers and CarPlay breakage(?).

Because these are persistent system modifications, this breaks analyticsd (and thus, services depending on it) even when “not jailbroken”.

Place an "x" between the brackets if true:

• [x] this is a bug others will be able to reproduce
• [x] this issue is present with all tweaks uninstalled(except for default packages) or disabled
• [unknown] this issue is present after a rootfs restore
• [x] this issue is present on the latest version of unc0ver

I suspect the developer @LinusHenze already knows this perfectly well but felt it should be formally documented, seeing how half the Issues on Undecimus are people trying to get Battery Usage to work again on unc0ver v8.
