小米路由R3G改SPI教程

ht619***

接到一台小米路由R3G救砖的活计，接上TTL一看，没死透，U-boot还在，TTL刷入breed 刷其他固件时一直提示坏块，无法继续。索性改个SPI启动好了，度娘找资料，只找到一篇拆芯片定位的帖子，贴主路由玩坏了，留下的资料经前任验证不可行。

启动原理图

电路设计

改造方法

J10   J11短接    R4上4.7K电阻 没有贴片的直接在SPI的3脚8脚飞线串一个直插电阻也行。详图

视频：http://v.youku.com/v_show/id_XMz ... j.8428770.3416059.1

breed 用MT7621 pbr1的。我用的MXIC闪存，固件基本上都会启动到交换机检测死机，不知道是植U没弄好还是闪存兼容问题，没空再弄了，初始是J11 J10都短接的，后期拆掉J10 一样进breed  固件启动故障依旧
付TTL 启动信息，我换了个华邦 依旧不行 排除闪存问题 可能是CPU重植没做好，有空在弄了

留名，之前就想看r3g改spi了

   有点无知，为何有晶振位置却没有接晶振呢

绝对咯，学习了，不知道有没有成功呢？

J10也要短接的吗？我的改造之后和之前一样TTL没有任何反应

昵称后面的数字不是我的QQ   只改R4 短接J10 J11试一下  我是先都短接了 后来发下J10不短接也行的   别的电阻不要动   动过的都恢复原位   R4要4.7K的电阻

TTL没有任何反应哇，刷了Breed也进不去，电脑获取不到IP，手动改也不行
