由于我自己的黑莓KEY2键盘空格键有问题了，于是收了一台不开机的黑莓KEY2当配件机，这是一台128G的工程机，是中国地区的，是开机没响应，充电也没反应，但是连接usb的时候电脑叮咚一声，看样子手机可能还没坏，于是找到高通的usb驱动，发现能进入9008模式，用emmcdl能查看到信息

Version 2.15
SerialNumber: 0x4f9fxxxx
MSM_HW_ID: 0x0008xxxx
OEM_PK_HASH: 0x7be49b72f9e4337223ccb84d6eccca4e71ce16e3602ac2008cb18b75babe6d09
SBL SW Version: 0x00000000
Status: 0 The operation completed successfully.

但是在写入文件时会报错, 提示设备没有正确反馈

Version 2.15
PblHack: Error - 4
Did not receive Sahara hello packet from device

Status: 6 The handle is invalid.

使用edl工具查看，能获取到不少设备信息，可以看到是高通SDM660的，还能往eMMC写入东西，启动不了并非是手机硬件坏了，大概率是eMCC分区损坏或者黑莓为了安全故意损坏了分区表，所以无论是充电还是按住开机键都没反应

于是我尝试去找对应型号的固件，但是发现这个所有的型号列表中没有这个工程机的型号，就找了国行版本其他型号的固件刷进去看怎么样，解压后发现刷机脚本只能用fastboot，目前这手机肯定用不fastboot模式的，只能在9008模式下用edl来操作，但是黑莓KEY2的固件就没有提供分区信息文件rawprogram0.xml等这些，我自己的KEY2暂时还没法备份出来，看样子如果官方不提供的话，只能自己根据当前固件文件信息自己生成一套才行了，只能暂时卡在这里了，等有时间再想办法。
