Android 救砖问题

起因：

手机突然所有应用运行都提示“ XXX ”已停止运行，然后就重启，结果按下重启之后，就无法再开机成功了。 接着进入 recovery 模式，链接上刷机大师， adb shell 查看，结果发现 /system 目录下全空了 就刷机吧，结果无法刷入，总是失败。

然后尝试救砖，结果还是无法刷入。 SP_Flash_Tool_v3 和 v5 都试过,Firmware Upgrade、Download、Format ALL+Download、MOTA SIU Like模式都尝试过，都无法刷入。刷机包都换了好几个了。

都是反反复复这两个错误：

PRO_INFO:failed to get PMT info

S_DL_PMT_ERR_NO_SPACE

BROM ERROR:??(8)

USRDATA: PMT changed for the ROM;it must be downloaded

现在手机无法开机，但是可以被 SP_Flash_Tool 识别读取。

着实没办法了，前来求助……
