最近从朋友那边看到一个fir302b的路由没人用放在那觉得可惜，原因玩的时候会卡。反正没人用拿回来刷刷看。
一开始用海蜘蛛按照他的说明来的用的webs升级。才上上去就没用了。。折腾了好几天看看有没有不拆机可以刷回的方法。
不过怎么试都没用设备死活不响应。
无奈只能拆开焊排针。

下面来说下刷机经验。
看来好多帖子。
1.有串口的情况先按住键盘ctrl+c 不然进不去。
2.进去后打 flash -noheader 【tftp地址】:/[文件名] flash1.trx
3.等待出现如下字
done. 3969024 bytes written
*** command status = 0
CFE>

4.拔网线后reboot
