前景提要：之前我那台128G的黑莓KEY2工程机由于只能开启高通9008模式，eMMC分区遭到破坏，因此官方的rom无法刷入，暂时搁置了。

  好歹我也是诺基亚时代的刷机小王子，夹具这种没技术含量的我也曾经也玩得不亦乐乎，这不想点招出来怎么能行，于是我另辟蹊径，寻找同为660平台的机型ROM，选择了小米Note3，然后尝试刷机，还真的刷进去了，刷进去之后发现插上usb后呼吸灯能亮红色了，拔掉usb线按电源键也能显示蓝色灯光，长按显示白色光，并且能震动了，看样子确实如我推测，机器硬件没有问题。
  既然能震动估计fastboot也能用了，测试一下果然可以，发现能连接设备了，直接用黑莓Key2的原固件尝试刷入，提示报错

报错信息很明显，缺少各种分区信息，cache分区大小不够，这样接下来需要做的就很明确了，就是编，看能不能编出一个固件结构刷入。
