如何移除正常激活的iOS 9.2～9.3.4但设置内退不掉的ID

自签/SSHRD注入Kok3shi9 Untether JailBreak，iFile/AFC2删除以下路径

/var/mobile/Library/Accounts/
├── Accounts3.sqlite
├── Accounts3.sqlite-shm
└── Accounts3.sqlite-wal

/var/mobile/Library/ConfigurationProfiles/
├── ClientTruth.plist
└── CloudConfigurationDetails.plist

/var/Keychains/keychain-2.db
/var/Keychains/keychain-2.db-shm
/var/Keychains/keychain-2.db-wal

没有则跳过，删完硬重启即可，设置内iCloud下账号消失。不可刷机还原，建议屏蔽更新+抹掉，然后导入iTunes备份其他机器无更新红点的备份。即可完美玩下去。

验证机型iPad Air 2+iOS 9.2.1。
