求助：K2升级到官方最新版后用breed Web助手通用版v2.8版本刷机后变砖

hhlyt

斐讯K2 A2版本机器升级到官方最新版本22.4.5.39后正常，但手多，又用“路由器刷breed Web助手通用版v2.8版本”软件想刷入Breed，但提示刷机失败，telnet服务未能开启，最可悲的是重启机器后找不到无线信号，也进不去管理网页，192.168.2.1地址ping不通，连电脑后，电脑网卡也分配不到ip，看来是变砖了。
拆开机器后，用TTL线查看启动信息确认是系统有问题了，系统最后启动到下面就停止了

看来是文件系统有问题挂不上了。
再次重新插电开机，然后迅速按下4，出现以下画面

看来可以登录MT7620控制台，？和printenv命令是我输入的，我想是否可以在电脑上建立TFTP服务器，把固件放在上面，然后通过
tftpboot命令将固件下载到路由器的内存中，然后再通过一些命令的方式将固件重新写入路由器，请教各位大神们，像我这样的情况是否还有救（我用低版本时刷入的Breed备份过eeprom.bin firmware.bin full.bin），有救的话麻烦贴一下详细的命令，小弟再次多多思考和感谢了！！！
哪位大神知道选2后该如何输入命令才能将固件重新写入路由器吗？

有哪位大神能解答一下？

最新版要降级才能刷机的

进入官方uboot网页恢复

电脑设置固定IP192.168.2.2，网关192.168.2.1，按住reset插电等一会松开，网页192.168.2.1进去刷就行

多谢各位，已经用uboot的2功能从TFTP服务器上下载原先备份的firmware.bin文件恢复好机器了。

我也是这个问题  请问怎么解决的呢？？？？

怎么能进入uboot的2功能呢？能详细描述下吗？需要做哪些工作，步骤?
和我的K2P情况一样，我刷入的是2.8 breed 助手，结果就进不去了，但是网线是显示连接的，只是前面是红灯,但电脑拿不到IP。无论是192.168.2.x 还是192.168.1.X
