Tutorial How to Fix Yalu102 when Crashing and Unjailbroken

Pro · February 5, 2017

Many people seem to be having an issue with Yalu102 where the app crashes immediately as well as being stuck in an unjailbroken state. Not only this, if you try to reinstall Yalu via Cydia Impactor, you get this error:

installation.cpp:42 Rejecting downgrade of system/internal app kim.cracksby.yalu102: installed version is 1, proposed version is 1

Having said this, let's get right into this fix.

Requirements:

- A computer

- Cydia Impactor

- The problems stated above

Steps:

1. Download the .ipa provided in this link: https://github.com/GeoSn0w/Yalu-Jailbreak-iOS-10.2. This is a fork of the Yalu102 jailbreak, so you will not get the installation.cpp:42 error when installing with Impactor.

2. Open Cydia Impactor, and drag the .ipa you just downloaded into there. You can then install that .ipa onto your iDevice without any problems, unless you have already installed 3 apps for the day.

3. Once you see "Yalu Dark" on your iDevice, go into Settings and trust the app just like you would any other app when installing via Impactor. After you've done that, open Yalu Dark and jailbreak just like you would with the official Yalu102.

4. Go into Cydia and either install or remove something that requires you to respring.

5. When you unlock your phone again, check to see if "yalu102" can open successfully. If it does open, remove both that and "Yalu Dark," and install a fresh .ipa of the official Yalu from https://yalu.qwertyoruiop.com/. If yalu102 does not open, repeat steps 4 & 5, as this did take two tries for it to work for me.

You should now be able to enjoy your jailbreak once again.

Nice tutorial dude , but just so people are aware this may not work for all users this could be because you may have already attempted to fix and caused more issues or the issue you're trying to fix is not this issue , so before you attempt this please be sure that you are :

Trying to fix the correct error as stated above in the original post by +Pro.

You have not already attempted to fix with another method and caused a different issue.

Please do be aware that this JB is temperamental and needs people to be careful with what they try to fix or install.

Hi do you have a fork version of ifile or filza as well?

I've done this but can't install anything on cydia as I lost the root ability on my phone. I can't root it using SSH as my ISP is blocking all ports when I tried tunneling it through port 22.

Thanks in advance.
