iOS固件升级到4.3.3,于是也来升级一下iTouch4的固件版本,结果还没到越狱步骤,在更新iOS过程中就出现了问题。提示:

无法更新iPod”Maple’s iPod”。发生未知错误(3194)。

从更新过程来看,应该是到苹果服务器进行验证过程中出错导致的。换了不同的网络环境都是一样,排除网络问题。后来从威锋上看到,说是修改了hosts文件导致的,因为有时候我们会在hosts中添加一些条目来改变域名走向,于是有了解决办法

自己尝试了有效的解决办法是还原c:\windows\system32\drivers\etc\hosts,内容如下

# Copyright (c) 1993-2009 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

# For example:

# 102.54.94.97 rhino.acme.com # source server

# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.

# 127.0.0.1 localhost

# ::1 localhost

保存,重新进行升级更新iOS操作,顺利通过了。

尝试过清空这个文件,竟然也不行,后来把这个文件内容还原才搞定,真是诡异的问题。

再p.s. 如果发现无法修改hosts文件,可以先将该文件复制到桌面上,修改完后在复制回去。
