1. Repair with Cydia tools
On 4s mobile Desktop we open Cydia install mobileterminal and then run mobileterminal then we then enter "Uicache" which means that we re-remove the desktop and reinstall the desktop again.
2. Delete some related files in the system
If the above method or not, you can use the PP assistant tools such as connecting the computer to find the iOS file system,
1./var/mobile/library/caches/com.apple.launchservces-056.csstore
2./var/mobile/library/caches/com.apple.mobile.installation.plist
Then we can rename the two files, like I changed them
1./var/mobile/library/caches/com.apple.launchservces-056.csstore_bak
2./var/mobile/library/caches/com.apple.mobile.installation.plist_bak
Yun-Habitat Community Small series reminder: Delete system files we must see clearly. If the deletion error may cause some of the system features to be unable to use or directly cause the system to hang oh, so if we can use the first method of repair do not go to test the second method Oh, because the second way to delete the file is very dangerous oh.
