记得那天早上开机 就卡开机画面 一天都没动，然后按照[webpad]大佬的 刷机方法 结果

USB未知设备 直接无法识别

然后上TTL线 https://www.right.com.cn/forum/thread-326314-1-1.html

线序 左到右  GND TX  RX VCC GND

开始跑马  ctrl+C 中断    8G 优盘  固件地址   发现16G或者以上的都不能用
然后开始输入升级命令

WIN7 没有这个功能 手动添加驱动 提示没有64啥的 ！

你的也是一样的问题吗?

可***

还是试试楼上添加硬件的方法吧。
我有个问题不知道怎么解决：rush的固件，我装xplore获取了权限，还是没法修改/system文件夹权限，adb什么也做不了。想装个谷歌也不行。

可***

把驱动重装一遍也识别不了吗

fante***

USB_Burning_Tool里有一个文件夹，带一个驱动文件，打上就好了，就是添加过时硬件，WIN7有，

USB直接无法识别，未知设备都没有

1.检查双公头线；
2.确定驱动已就绪；
3.线刷模式，安卓安装终端模拟器，或者通过adb shell执行reboot update,linux直接执行reboot update，自动重启开始刷机！

开机只有灯亮，没有了信号输出
