1-Rramdump 获取
基本思路： 手动产生dump ， 使用QPST 抓取
1.1， 手机进入dump mode
进入手机的终端，输入指令
echo 1 > /sys/module/msm_poweroff/parameters/download_mode
echo c > /proc/sysrq-trigger
1.2, 手机处于DUMP 模式，可以抓DUMP LOG.
确认USB 驱动正常：

如果不能正常，下载驱动精灵，进行usb 驱动安装

1.3，打开QPST自动抓取

adb bugreport bugreport.zip
如果/sys/fs/pstore/ 没有文件，就会有下面的log
*** Error dumping /proc/last_kmsg (LAST KMSG): No such file or directory
code 路径：
frameworks/native/cmds/bugreport/bugreport.cpp
frameworks/native/cmds/dumpstate/DumpstateUtil.cpp:183:
dprintf(out_fd, "*** Error dumping %s: %s\n", path.c_str(), strerror(err));
