我的Nexus 5用了两年，电池也是越来越尿崩，从一天一充到一天三充。出门在外，接上充电宝使用，越充越少。结果没电关机，自己失联了好几次，耽误了很多事情。
于是入手了Nubia Z11，2.5D玻璃屏幕，看起来几乎没有边框，外观漂亮，性能也不错，续航还行，快充，适合日常使用。
Nexus 5闲置之后，待机居然能超过一个星期，终于找到电池尿崩的原因了，装的东西太多。
另外用和我名字一样的人的信息在网上办了一张手机卡，却发现现在要实名了，手持身份证不说，还要身份证和电话卡包装合照。
开始折腾我的备用机，首先刷回官方的固件。谷歌原厂镜像
进入系统后，安装自己的梯子，还有最重要的酷市场
因为我的电源键失灵，经常是按住的状态，导致关机或者不停重启，可以看到插卡处也裂了（很多人的手机这里都裂了），我只好把它拆了。
在GravityBox里把音量键换成电源键，双击虚拟home健熄屏，设置听歌时不能调音量，这样听歌时也能唤醒手机了。
Nethunter自带的就不说了，这里推荐几个不错的应用
我是Archlinux用户，使用KDE，于是我安装了KDE Connect桌面端和移动端 ，作为手机与电脑的无线连接工具。
最后刷入Kali Nethunter。Kali Nethunter尝鲜 但是不适用于现在了。
我安装完Nethunter，发现postgresql服务不能启动
1 2 root@kali:~ [....] Starting PostgreSQL 9.4 database server: main[....] The PostgreSQL server failed to start. Please check the log output: 2016-10-08 12:18:03 UTC [5618-1] FATAL: could not create shared memory segment: Function not implemented 2016-10-08 12:18:03 UTC [561[FAILDETAIL: Failed system call was shmget(key=5432001, size=40, 03600). ... failed!
使用shmget函数出错，发现是共享内存这里有问题。初步判断可能是设置的值过小。
1 2 root@kali:~ cat: /proc/sys/kernel/shmmax: No such file or directory
查看一下内核中发现并不存在这个属性，这就尴尬了，于是不断Google，终于在Offensive Security 的 Github Issues 上面看到了同样的情况。他们已经Patch了，但是官网上面的还是没变，需要自行打包。
那么我就开始打包吧，其实不是Nexus5也能刷入Nethunter官方Wiki ，一步一步操作
1 2 git clone https://github.com/offensive-security/kali-nethunter cd kali-nethunter/nethunter-installer
这里只能用Python2构建包，查看说明后，运行如下命令，参数大概是Nexus5的代号hammerhead，目标系统marshmallow，仅打包Kernel。

打包完成后会在目录下生成文件，通过KDE Connect传入到手机，重启进入REC刷入。大功告成！！
最新的Nethunter使用的是kali-rolling源，如果更新源或者下载包失败的话，请把源更改为
1 2 deb http://http.kali.org/kali kali-rolling main contrib non-free deb-src http://http.kali.org/kali kali-rolling main contrib non-free
