iOS App Disappear after iOS 7.1.1 / 7.1.2 Untethered Pangu Jailbreak
Chinese iOS 7.1.2 jailbreak problems is not news as there were some issues with 7.1.1 jailbreak on Mac or Win as well using the same tool. Apple has just updated its firmware and a lot of people were fast to use the exploit with further jailbreak bugs on iOS 7.1.1 and 7.1.2 versions.
As people note, the bug on iOS 7.1.2 jailbreak makes app disappear from your Home screen. This is pretty weird but people keep complain about the problem. It’s hard to say at the moment whether iOS 7 app disappeared from the Home screen because of Pangu or for some other reasons.
It could be possible that the iOS 7 apps disappear after jailbreak but because they are incompatible jailbroken programs with Pangu exploit. Some experts believe the 7.1.1 jailbreak issues might surface because of the .plist file not loading the correct way.
If you simply delete the jailbreaking tweak, the bug should be gone. The question is how you can find which tweak causes the bug in order to delete it. Everything is not as simple as if you have a lot of tweaks loaded on your iPhone or iPad you will have to remove them one by one checking if the problem is gone and when.
Pangu jailbreak and app disappear issue can be solved in another way as well. As some Reddit members note ReddestDream and kozerq, you can try to run “uicache” comman via OpenSSH or MobileTerminal [to fix the .plist file and icons] or remove com.apple.mobile.installation.plist and com.apple.LaunchServces-056.csstore files located in /var/mobile/Library/Caches/.
Note that the solutions above might mess up the layout you are used to. Whenever you delete your system files you might cause another problem so do this only if you are sure you are doing everything correctly and won’t ruin your devices OS.
