我的ipad2才买几天，没有越狱，电池满的。
中午的时候，在itunes里面把iOS5下载好，一共700M。然后插上iPad2更新。
开始之后就没管它了。过了一会儿，回来一看，itunes里面的界面恢复正常了，但是ipad的界面还是显示的连接itunes。
我关了itunes再一次启动，itunes自动开始恢复，恢复了一半，出错了！！弹出对话框提示说不能恢复！
然后再来一次，还是出错。
各位大大，这是什么情况，请告知。在线等。

我也出错，我放弃了，软件重新安装即可，设置的东西自己弄。

错误提示能说详细点么

你的电脑搞过JB吧？  是不是HOST被改了？去掉JB的那部分就可以了

首先谢谢LS各位。
我补充一下：升级并没有成功，现在我的IPAD启动不了。出错是在恢复的过程中出现。我专门截了图上来。请高手看看。

重新恢复了7、8次后，突然就成功了……这个完全搞不懂……

这个我也遇到过，说磁盘空间不足，其实是C盘满了，清了下垃圾，就不会报错了

Error 1604: This error is often related to USB timing. Try changing USB ports, uninstalling and reinstalling USB ports, and other available USB troubleshooting steps (troubleshooting USB connections, device not recognized properly, computer won't recognize a FireWire or USB device). If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.

If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:

Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
Restore and wait for error 1604.
When prompted, click OK.
Close and reopen iTunes while iPhone remains connected.
iPhone should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
