求救，FW300R V2变砖了

my***

从openwrt 110829版本直接在WEB页升级120119，没有保留配置，升完以后路由器就不通了，指定IP把电脑接到LAN1－LAN4,WAN都试了，还是不通，重启的时候，所有灯会一起闪一下，SYS和WPS也会一起闪两下，接着就所有灯都不亮了，除非把电脑接在LAN1-LAN4、WAN对应的端口会亮。用TTL线登录，出现如下信息，停止不了

有乱码，尝试把C496短接，但是短接后便连不上了。

之前我记得有位网友发过，只要把固件改名为XX，用TFTP还是什么，接好路由器重启就会刷入的，求详细方法。

如果用TTL怎么才能让它停止，用了TPL、P、TT等都没能让它停下来

你这个是tthr的u-boot1.3.0?

那是按着WDS键启动，然后在IP为192.168.1.23的电脑上的tftp服务器下载名为factory.bin的固件。
“添加了对开机时qss按键的支持，当固件刷新失败后可以在重启时按住qss键直到看到除wifi外的led闪烁３次,uboot会自动进入tftp模式并下载目标主机(192.168.1.23必须是这个地址哦)上名为factory.bin(将你想烧入的固件改成这个名字就行了)的文件，并自动写入到flash中。”
TTL的话，在“Autobooting in 1 seconds press tt to abort”时用tt来停止，你SecureCRT里的流控制关了没？
你说C496短接后不能连接，是什么状况？你确定没短接错？
tthr的u-boot有时好像会抽，我记得我曾经用它的WDS键刷固件时失败过，TTL里刷U-boot似乎有时写不进去，最近一次实验却没有问题……奇怪……
一起闪两下没错，正常。
你刷的trunk？那货我记得官方版没有luci……看你好像是8M的，不过不像是dyq的额……官方版支持8m吗？我现在用自己编译的backfire r32751……
