回复于：power m3求root

老哥我往上只找到了 iwork8的adb工具

输入fastboot oem unlock的时候出现报错设备未经授权

如果你手里有power m3的ADB工具发我一份，另外我用MTK的刷机工具来刷你在楼上提供的线刷包的时候，检查驱动都装好了，到底是在平版处于什么状态才能刷呢？我进入到了fastboot界面都刷不进去。望不吝赐教。

This adb server’s $ADB_VENDOR_KEYS is not set
Try ‘adb kill-server’ if that seems wrong.
Otherwise check for a confirmation dialog on your device.
