If you are using an A12 device, chances are your tweaks won’t show up in the Settings. Here’s a quick fix for the PreferenceLoader issue that seems to be plaguing all Chimera jailbreak users.
Table of Contents
Why are tweaks not showing up in Settings on iOS 12?
The problem stems from the lack of tweak support for A12 devices. As you already know, most tweaks lack a functional preference bundle on the all-new Chimera jailbreak.
Besides, users are having troubles installing the RocketBootstrap developer package using Sileo, which is further rendering preference bundles broken.
If you try to access a tweak’s preferences section, you will be greeted with the following message –
There was an error loading the preference bundle for <tweak>.
Thankfully, NepetaDev promptly released an update to Cephei, which fixes PreferenceLoader issues for A12 device users.
Warning – Your setup will break completely should you decide to give this tutorial a go on an A11 device (iPhone X or below).
How to fix PreferenceLoader error in Chimera jailbreak
Step 1 Open Sileo and navigate to the Packages section. Alternatively, you can open Sileo straight from the jailbreak app.
Step 2 Navigate to Sources and enter the URL of Ryan Petrich’s repository (https://rpetri.ch/repo).
Step 3 Open the Packages section and tap the button present alongside “Date” and open the Developer tab. This tweak is hidden and is accessible only through this tab because it’s aimed at developers, not average users.
Step 4 Add NepetaDev’s source (https://repo.nepeta.me) to Sileo and install the Cephei Debian package.
Step 5 Restart your iPhone or iPad.
Step 6 Open the Chimera app and re-jailbreak your device.
The PreferenceLoader will now become functional and your tweaks should start appearing in the Settings app like they are supposed to.
If, however, you are unable to get them to work, your tweaks have probably not been updated by the developers for A12 devices yet.
A lot of packages including Dune, Jellyfish, and all of NepetaDev’s packages are already updated. The ones that still have broken preference bundles should get updated pretty soon.
wow amazing man its worked on iphone 7 ios 12.1.3 via unc0ver 😀
I fixed by this way. iPhone XS (A12) iOS 12.1.1
LibertyLite doesn’t worked before. Now fineeeeeee
Hey Gian, this totally worked for me.
As GamersSTDs mentioned above, “the only “Cephei” is thru Hashbang (bigboss).”,
I re-downloaded that Cephei package after adding the Ryan Petrich’s repository (https://rpetri.ch/repo) to my source. It took a couple of attempts to download the repository, but it worked after multiple attempts.
Then I turned my phone off and back on to realize find out that the error doesn’t exist anymore!
Thanks for the help. I know a lot of people said delete this article, it doesn’t work, and blah blah.. but I appreciate your help and the effort to trying helping others.
That’s great, Yass. Glad it worked for you.
Hello. So I’ve set the new repos and everything but when I open chimera it says “Already Jailbroken” without the option of rejailbreaking.
Did you reboot your device? If you didn’t, you will not get the option to re-jailbreak.
Same as Nouf
Iphone XSMAX ios 12.0
i did everything and the sources are not working also im on iphone Xs 12.0.1
Which version of Chimera are you using?
Maybe you guys will be a little more helpful than the reddit.
I’ve tried, this. I’ve tried reinstalling Chimera through the computer option. I’ve attempted to get into SHH but I can’t do that either. I’ve reset rootfs. None of this stuff is working. I have an iPhone XS on iOS 12.1.1 Apps that are supposed to work like Liberty and ChromaHomebarX don’t work for me.
I would highly recommend doing a RootFS restore and then reinstalling Chimera.
i have an iPhone 6 plus runs 12.1.2 (16c101) – and there’s no preference loader under rpetri.ch repo! nothing works completely. i’m lost with handling which one stuck jailbreaking.
You need to switch to Developer Mode in Sileo to access that package.
I have the iPhone XR. The Cephei is not showing in the repo even when I’m in the developer section. Can someone help? I have the Cephei installed from another source but it doesn’t work.
Switch to Developer Mode in Sileo.
Cephi isnt on the added repo, its on big boss.
Still not working
Xs max, ios 12.0
Try switching to the “Developer Mode”.
I’ve tried this method because I unjailbroke and rejailbroke and I don’t get errors installing tweaks and they show up in settings but I get unable to load preference bundle. Please help.
Some tweaks haven’t been updated by the developers yet so they won’t show up in the Settings. Which device are you using?
Not working for me. There appears to be no Cephei on Nepeta’s repo. I refreshed the sources and restarted the app and nothing. I DO have a Cephei installed already by another repo but im still having this preference loader error issue. I tried reinstalling Cephei with no success. iPhone Xs Max iOS 12.1.2
Try switching to Developer Mode on Sileo and then install the aforementioned packages.
This does not work at all! There’s nothing on Nepata. Delete this article it’s not helping us.+
Have you enabled “Developer Mode”? If it’s still not working as expected, just use unc0ver jailbreak on iOS 12 and above versions.
i still work not some a12 tweaks
i also my device is iphone xs ios 12.1.2
jumper is PreferenceLoader error
Try switching to unc0ver.
Hi, I don’t know for what strange reason, but to me from error and doesn’t install the repo and neither the corresponding packages.
Do you know if it happened to someone else and how to solve the problem please?
Can you upload a screenshot? Have you tried installing packages from Filza?
I saw the correction you made, inserted the repo you wrote and obviously made a mistake … now I’m like GamerSTDs.
I have iPhone XS MAx and the only version of Cephei that I find is that of Hashbang.
There is no presence of that of rpetri
Try using RootFS Restore.
So just couple of things. The repo is wrong, it should be (https:/repo.nepeta.me).
But even after adding it, the only “Cephei” is thru Hashbang (bigboss). Which indicates that we added those 2 repos for…. nothing?
This did not work for me. Any other suggestions?
Thanks, I have updated the article. Try refreshing your sources, Nepeta’s repo has a new version of Cephei. Which device are you using by the way?
Nothing in this article worked. What actually worked for me was to restart my phone, open the Chimera app and tap on Reset root (or something like that) which by the way, that will delete all your tweaks and sources, it will give you a bran-new jailbreak, and then I tapped on Jailbreak to complete de process.
Everything has been flawless ever since.
I am on XS Max running 12.1.1
That’s called RootFS Restore. Glad it worked for you!
Hi, it still doesn’t work on iPhone XS Max …. can we fix it otherwise or do you have any suggestions?
just add source then delete cephe it will be fix amd reinstall pereferenceloader
still not working
Which device are you using?
