作者原文
here's how to reset applocker's settings:
[align=-webkit-auto]
just delete this file:
/var/mobile/library/preferences/com.nnfyrbsnss.applocker.plist
doing this will revert all of you applocker settings (password, locked apps) so you can go to settings and make sure what password you type in this time.
i hope that helps you. if you need any more of assistance, email me. i'm trying to reply immediately (if i'm not sleeping).
let me know how this goes.

方法是用 ifunbox 删除 /var/mobile/library/preferences/com.nnfyrbsnss.applocker.plist
