nexus5 线刷5.01
我当初是用这种方式：
http://www.igao7.com/news/201406/nexus-root-ota.html
https://goo.im/devs/WugFresh/NexusRootToolkit/
来root的5.0，结果ota不行，
据说只能线刷5.01.

刷机精灵，想刷个cm的4.4，结果rom 脚本错误，让换ROM，
提供了一个救砖教程：http://www.shuame.com/faq/restore-tutorial/3396-google-nexus5.html 貌似是4.4.2的。
但是这次失败的刷机，在重启，等待很久开机后，发现是5.0，且清空了所有数据，
启动的的时候，会让你设置很多，谷歌的服务就不要开启了，不要当小白。
有个输入姓名的地方，我输入了中文，结果死活过不去。
检查网络连接，用了很长时间！
