本文详细介绍如何将iPhone进入及退出DFU（恢复）模式。首先确保电脑开启且已运行iTunes，然后按步骤关闭iPhone并连接至电脑。通过同时按下睡眠和主页按钮十秒，再单独按住主页按钮十秒即可进入DFU模式。此时iTunes会检测到处于恢复模式的设备，并提供恢复选项。退出DFU模式只需再次同时按下睡眠和主页按钮直至设备重启。

Entering DFU (Recovery) Mode
First, ensure that your computer is on and iTunes is running (having iTunes running isn't necessary, but will save a bit of time later). Next, power off your phone by holding down theSLEEPbutton on top of the unit until the power off slider pops up. Slide your finger across the power off slider, then plug in your iPhone's data cable to both the iPhone and the computer.
Next, Hold both theSLEEPandHOMEbuttons down for 10 seconds, then release theSLEEPbutton, but hold theHOMEbutton for 10 more seconds. Your iPhone will have a blank screen, but should be in DFU (recovery) mode.
At this point, iTunes should detect a device in recovery mode and give you the option to resotre your iPhone. If iTunes doesn't detect you iPhone, verify that you don't have OS X 10.6.5 (see note above). If not, try the process again.
Exiting DFU (recovery) mode
Exiting DFU mode on your iPhone is a much easier process. Simply hold both theHOMEandSLEEPbuttons until the iPhone begins to boot up. Release the buttons, and that is it, you are back to normal iPhone operation.
