就停止不动了，ping 192.168.1.1不通，但还可以当傻瓜交换机用

我用以下方法救回wrt610n v2

短接閃存第8,9針5秒, 然後用TFTP上載原廠固件, 就搞定了,

注意: 要搞錯針腳, 不然會燒閃存

https://dev.openwrt.org/ticket/13372

Try turn off and disassemble router, find flash chip


short pins 8-9 and turn on, after 5 sec unshort pins, try to ping 192.168.1.1, TTL should be 100, upload firmware with TFTP, and wait for the router reboot.
