R3G能用U盘刷系统吗？刷机断电变砖求救，网线连接进不去breed

jc3***

已经刷进去breed，通过breed刷openwrt底包页面超过半小时就一直没动静，断电之后就进不去系统了（刷之前是官方开发版系统），之后通电什么都不动，路由器只会进入breed一直闪蓝灯，但是这时候再插网线链接电脑，192.168.1.1就再也进不去了，链接有叹号，今天ttl链接后台，能读出信息，但是因为网线无法通讯，putty64没反应

网线3个口，刚开始还都能用，现在只有最边上的LAN口插上还能亮

网口不行，有办法从U盘重新刷breed或者直接刷openwrt固件的方法吗？

插上u盘 ls /mnt/shares 看看又没做显示你的U盘路径，有的话再cd /mnt/shares/ 看看

ttl用Xshell连接上，后台进的应该是breed，is和cd命令好像都用不了
