水星 MW300R TTL救砖 乱码 急救~~谢谢

夜游神

mw300R 不小心刷成砖了，通过TTL连接路由，终端显示乱码
波特率115200，设置应该都是对，搜索了一下，貌似需要短接C496电容，才能不乱码？
求教高手，赐教详细操作步骤，那个电阻是在什么位置？怎么短接？
谢谢！

图中有个C496，不知道是哪个，怎么去短接操作？

自己看定义。

夜游神

找到了，就是C503下面的那个。
不过还有些乱码，而且无法输入

短接了吗？就是用线直接联起来。

嗯，短接了显示不一样，但是无法输入。是不是要把c496给铲掉，再短接？

是的。

夜游神

铲掉以后，如果救活了，还需要再焊回去吗？

夜游神

yuanhuafly，谢谢回复。铲掉之后连接不乱码了，但是无法输入。
按此贴做http://www.openwrt.org.cn/bbs/fo ... thread&tid=3617好像不行。
看来要找一下MW300R的4M的救砖办法了········

哈哈！搞定啦，原来连接到路由时，需要速度按下TPL 才能到输入命令的步骤
谢谢yuanhuafly兄弟回复！

作个有前人

请问一下路由器的主板上如何区分GND、RX、TX、VCC？

好帖收藏，

我的也是乱码，试试看

liveasx

设置波特率128000即可  没有就手动填,MW300R V4
