首先,根据某度贴吧的帖子中兴光猫F673A V2 TT线修改管理员密码,可以看出TTL接线方法,开机只能到starting kernel ……就停止了,然后根据这个中国电信光猫 中兴F650破解,获取超级密码,去除各种限制能进入命令(就是按下光猫开机按钮后)按回车键进入中兴的U-boot界面,只能输入特定的命令,root输入不了,最后根据某瓜视频中兴F460 V6.0版本移动光猫ttl获取并修改超级管理员密码,还是只能到starting kernel ……停止,无法输入login:root,password:root,这个命令。 由于没有破解完成,第一,希望大神出出招,按光猫按钮之前是不是需要短接什么或者主板芯片存在什么问题(本人猜测),但是光猫正常使用,就是会偶尔丢包,打游戏时会卡顿(个人认为),毕竟宽带维护人员测试后一切正常。第二,希望能给后者(学习的人)一个借鉴的经验。
