9.2.1 4s 越狱降级到 6.1.3 系统


前言:

最近 iPhone 4s 9.x 系列的越狱工具 Trident 出来了,对于非 9.3.5 的 4s 用户来说又迎来了降级 6.1.3 的机会。

在威锋上看到已经有人做出了新的降级教程,心痒难耐,果断把自己的 4s 掏出来,试着开始降级。

中间的尝试过程略去不表,只说最终我使用了的方法。

原本的 4s 越狱过程是需要登录到 4s 上,启动一个 kloader。然而这一次的 Trident 越狱并没有安装 cydia,所以在网上有人做了 Trident + kloader 的软件版本,在越狱完成后,直接运行了 kloader 加载的相应的文件。

我们需要的工具有:

1. Trident-kloader.ipa
2. idevicediagnostics for windows
3. fistmedaddy.ipsw

具体步骤:

我们需要进行的操作步骤是:

  1. 安装 Trident-kloader 程序,点击一次 start 按钮进行运行,之后等待手机苹果花屏一下。start 按钮点且只点一次,请谨记。点击完成,屏幕花屏一下之后,屏幕上应该会显示 w00t root,此时手机处于了已越狱 + kloader 加载完毕的状态。
  2. 使用 idevicediagnostics 中的 idevicediagnostics 命令,执行
    idevicediagnostics.exe sleep
    
  3. 待到设备黑屏,按几下home键。如果设备屏幕没有亮,此时设备应当处于了 DFU 模式。如果屏幕亮了,请关机重启,返回步骤 1 进行执行。
  4. 设备进入 DFU 模式后,使用 idevicediagnostics 工具中的 idevicerestore.exe 工具,执行
    idevicerestore.exe -e ..\fistmedaddy.ipsw
    

    然后可以看到以下 log 信息:

C:\odysseusOTA4WIN\未命名文件夹 3\idevicerestore for Windows>idevicerestore.exe

DONE

最终出现 DONE 后,手机会进入恢复模式,可以看到界面变成了 6.1.3 的样子。等待恢复完成,成功的回到了 6.1.3 系统。

注意事项:

  1. Trident-kloader 我是从源码编译的,最初几次点完了现象不正常,可能是因为我安装了多个 Trident。最后只剩下一个 Trident-kloader 的时候,关机-开机-运行 Trident-kloader 执行后,成功了。成功的效果就是屏幕右侧花了一下,其它并没有任何异常。
  2. 在执行 restore  的时候,最开始一直会报错,错误信息如下:

导致这个错误的原因是在 hosts 文件中,gs.apple.com 被重定向了。解决的方法是,打开 hosts 文件,删掉 gs.apple.com 的信息。 hosts 文件位置:

C:\Windows\System32\Drivers\etc\hosts
