mtk7621A 硬改问题，求大神指导

oliv***

本来想自己加个usb，没想到手拙到变砖了，现在开机蓝灯，过一会变红灯，ttl可以连上，breed似乎也有，但是电脑连接路由器lan口无反应，显示未连接，不知道该如何处理了，求大神指导



ttl停止的截图

好像有breed？但是没法连上路由器。。。

交换机烧了？，是A2版本吗？，

oliv***

使得，交换机是哪个呀。。可以换一下吗。。。

goo***

mt7530. 应该是集成在mt7621 soc里的。

gmf***

交换机CPU集成的，感觉，k2pA2版的有些批次可能有严重的质量问题。我的A1版本的就没坏过。A2版本的到手里，插上电源用了下就坏了

goo***

32M flash，512M内存。应该加U前，已经硬改过了。

没接地吧，很多人都因为这个烧了
