若直接在 iTunes 里更新的,固件保存目录如下:
Mac OS: /User/用户名/Library/iTunes/iPhone SoftwareUpdates
WIndows XP: C:Documents andSettings用户名Application DataApple ComputeriTunesiPhone SoftwareUpdates
WindowsVista/7:C:Users用户名AppDataLocalAppleAppleSoftwareUpdate
Shift+更新(Win)Option+更新(Mac)为升级固件,部分数据不会被清空
Shift+还原(Win)Option+恢复(Mac)为还原固件,会清空原有数据
DFU模式下还原固件,会完全清空全部数据
刷官方固件会使设备从越狱状态变为未越狱状态,同时会升级基带版本。
越狱方法未验证:
锁版机器请使用PwnageTool刷去基带升级的自制固件。非锁版可以使用redsn0w或pwnagetool越狱。
备份通讯录
方法1
如果机器已越狱,可以将/var/mobile/Library/AddressBook/中两个文件传到电脑上。越狱4.0后将这两个文件传回原目录,并设0644属性,mobile用户和组。
方法2:syncinablink将通讯录备份到Gmail账户,之后再还原 |QQ同步助手也可以在线备份,而且可以免费在iTunes里下载
方法3:刷新固件之前直接备份整个设备,但此方法在还原备份时可能需要很长时间,也会有一些垃圾数据。
