居然不是用25系列:L,砖了的话，很难救呀 很多都能刷啊，有些固件不分内存类型的，但分内存类型的多一点，比如MT7621刷爱快只能刷NAND的内存，有些路由器还要硬改才能刷上。推荐刷老毛子吧，稳定，不掉速。OP也行吧，只不过自己不会编译的话，无线速率可能就没那么好，信号强度也可能比较差。 rj7can 发表于 2021-9-29 07:49

现在很尴尬，不知道怎么刷breed或者opboot进去，ttl一点机会都不给 7621的最佳对应老毛子应，要编译wu线网卡驱动就可以了 7621的最佳对应老毛子应，要编译wu线网卡驱动就可以了 lzy2005 发表于 2021-9-30 19:39 static/image/common/back.gif
现在很尴尬，不知道怎么刷breed或者opboot进去，ttl一点机会都不给
按住复位，ttl设置好进去，插电按2或者Ctrlc看看能不能
等抄大佬作业 TTL下不可以操作吗? 我在研究这机器,但是找不到方法,只能用编程器先写个pd-boot到空nand里换上去看看,但编程器太贵,我又在学习用旧路由改简易编程器,反正都是要动电烙铁 手里好多这个，加个关注。能刷就舒服了。 我都已经把闪存拆下来了，背面有sop8的焊盘 但是缺几个电阻，不知道如何下拉实现sop8焊盘的闪存启动 来个tp工程师泄密下 :victory::victory::victory::victory: 网络虫子 发表于 2023-2-12 22:48

可以参考k2p的上下拉电阻。不过需要有人提供一下。
