The IPhone 4s has been upgraded to IOS7 and has been out of prison for some time and has been used well. As a result, when the power was turned off yesterday, the software icon on the screen was gone. Only a few of the original applications plus Cydia installation of the application, good catch.
Help the Internet, find a solution, as follows:
Open the cydia– management on the device – package – Locate the IPA patch (appsync for iOS7) after uninstalling.
Use the phone-side file Management ifile (no words installed in cydia), delete/var/mobile/library/caches/ Inside of the Com.apple.mobile.installation.plist and Com.apple.launchservices-054.csstore (without a pipe) after the file is deleted, reboot the device.
Re-open Cydia Add Source: cydia.myrepospace.com/tushaoye/installed appsync_fix7.0 can be used normally (do not install appsync7.0, this plug-in replaces its function)
Okay, all the apps are back, haha ~ ~
