No matter how advanced a user you are, you can still get errors while tinkering around with a jailbreak. These tools are unofficial and using them can be a daunting task. Follow our Troubleshooting FAQ to fix all errors Yalu throws at you.
Table of Contents
JAILBREAK RELATED ERRORS
Q. Should I use this jailbreak?
A. Substrate is disabled by default so you need to enable it after each reboot using mach_portal.
Q. Is it safe to use the “Erase All Content & Settings” function in Settings?
A. No. If you do this and try to use Cydia, you will get “Could not open file /var/lib/dpkg/status – open (2: no such file or directory)” error.
A. Kill Settings with app switcher and search for it again.
Q. Why are my Apple ID and password not accepted by the jailbreak tool?
Q. How do I fix cellular data, iMessage or Facetime not working?
A. Follow the tutorial here. If it still doesn’t work, try resetting your network settings.
Q. I get this error message after entering my Apple ID and password – “provision.cpp:150 Please Sign in with an app spesific password”. How can I fix it?
A. Follow this tutorial here to fix this error.
Q. iFile is not working on my device. How to solve this issue?
A. Just use Filza app.
Q. Can I downgrade from iOS 10.2 to iOS 10?
A. Unfortunately, it’s not possible now. DO NOT update to iOS 10.2+ in any case. Your best best now is to wait for an iOS 10.2 jailbreak.
Q. Should I install YUCCA utilities with Yalu?
A. No. This could cause issues in the future. It is strongly recommended that you do not install them.
Q. Can I install OpenSSH?
A. No. There is already a working SSH that comes with the jailbreak. If you use OpenSSH, it will cause issues with the final jailbreak. Follow this tutorial to properly SSH into your iOS 10 device.
Q. How long does this jailbreak last?
A. Yalu jailbreak will keep functioning even after 7 days as long as your device doesn’t reboot. If your iPhone/iPad reboots and Cydia tweaks keep crashing, you will need to run mach_portal/yalu102 app again. Re-jailbreak procedure is explained in detail in our jailbreak tutorial, so follow that.
A re-jailbreak every 7 days is still recommended as any bogus Cydia tweak can result in a reboot. This will put your device in unjailbroken state. If your jailbreak certificate expires, you will lose the jailbreak until you can access your PC/Mac.
Q. Yalu jailbreak on my iOS device expired in just 3 days. What did I do wrong?
A. You must have deleted it and installed it again after 4 days. Cydia Impactor tool does not resign certificates. So if you deleted and reinstalled Yalu, 4 days after installing it, you will only have 3 days left.
Q. How do I disable OTA so my device doesn’t try to update?
A. Install the tvOS configuration profile to disable OTA updates.
Q. How do I change my root password?
A. In any terminal client, such as NewTerm or MTerminal, (or via ssh by running ssh [email protected], replacing the x’s with your IP address and the password as follows). The default password is “alpine”. Once logged in, run “passwd” and type in your new password twice. Then run “passwd mobile” and type in your new password twice.
Q. How to check if my device is in jailbreak state or not?
A. Here’s a nifty little trick that lets you do exactly that..
- Download Icon Renamer tweak via Cydia.
- Now respring and tap the mach_portal icon.
- Rename it to ‘Jailbreak On’.
- That’s it. If your device is in jailbroken state, mach_portal app will read as “Jailbreak On”. When your device is not jailbreak state, it will just display as mach_portal.
Q. How can I add an icon to mach_portal app?
A. If you are interested in modding its icon, use this step by step method for Windows and Mac OS X.
Q. Whenever I enter commands in Terminal, I end up with a reboot. What am I doing wrong?
A. This error is happening because you aren’t pressing enter/return key after each line of code.
Q. Can I restore to iOS 10.1.1 using iTunes?
A. Yes, it is possible but only if you have saved your SHSH2 blobs.
Q. My device keeps rebooting/crashing randomly on 10.1.1 jailbreak?
A. This issue can be solved easily using a terminal command. We will remove all corrupt files and remove them.

Q. After installing Yalu jailbreak, my battery performance has been reduced. How can I fix battery drain after iOS 10 jailbreak?
A. Battery drain occurs because you have installed too many tweaks. Try removing them one by one as one of them is the culprit here. Make use of Low Power Mode to save battery
Q. App Store is not working after iOS 10 jailbreak. How can I fix this?
A. There are several fixes you could try as there is no single solution to this problem.

- Press the Feature tab 10 times. Doing this will restore the App Store.

Q. I keep getting “Failed, Retry” error with Yalu jailbreak. How do I solve this issue?
A. Close all apps and then try again. When you open Yalu, wait for a minute and hit “go” only once.
Q. All of my tweaks are gone after rebooting. How can I fix this?
A. Try uninstalling iCleaner from your device.
Q. I deleted the mach_portal icon by accident. Cydia is crashing incessantly now. Is my device bricked?
A. Cydia is crashing and not working because you can’t get into jailbreak mode. Mach_portal is necessary to getting your device in jailbreak state. You device is not bricked, it just needs to be jailbroken again. Here’s what you have to do now to restore the jailbreak…
- Delete app and profile.
- Download Cydia Impactor and Yalu jailbreak beta 3 using the links given above.
- Follow the steps given above to install Yalu through Cydia Impactor.

- Run mach_portal. Done!
If this process is not successful in the very first try, perform it again.
Q. My jailbroken iPhone 7 is not turning off. After powering off my iPhone 7, it just reboots to non-jailbroken state. How can I fix my iPhone 7?
A. This error arises due to conflicting Cydia tweak. Just uninstall the exKey tweak from your device. This tweak is known to cause issues as it conflicts with Activator.
Q. Whenever I run the mach_portal application, my iPhone 7 resprings. How do I fix this?
A. Open any 8 system apps (such as Camera). Run mach portal application and the jailbreak process will be successful.
Q. How do I restore my device to stock settings without updating my firmware?
A. You can use OSRestoreX or Semi Restore 10 for restoring your device. These tools erase your data while still keeping the firmware same.
CYDIA RELATED ERRORS

Q. When I use “Restart SpringBoard” in Cydia, I get stuck on a blue screen. What should I do?
A. This happens due to Cydia trying to relaunch backboardd when tapping this. This is broken with this jailbreak so you must use a terminal app (or ssh) and type killall -9 SpringBoard. This does not work with every tweak but seems to be the best method at the moment.
