8953n的user获取权限以及remount

  8953n的user 想要root的话 不太方便，

当需要push文件到system下时，需要执行如下步骤：

1.     先使用FDSS signature Unlock机台，通过此方式解锁机台，便能够获得root权限

(a).在fastboot下使用           fastboot_89xx getvar cpusn ，获得CPUID

(b).将该CPUID发给PM，说明需要unlock机台。PM会回传一个signature文件

(c).将该signature文件用       fastboot_89xx flash asus_unlock signature         ，即可unlock机台。

 

2.     此时开机便可以使用     adb root

3.     adb root之后，下命令  adb disable-verity，然后重启机台

4.     重启之后便可以使用     adb remount命令，可以adb push文件到system目录下

这里的matthew@matthew:/media/matt2/8953-N/out/host/linux-x86/bin$ ./adb disable-verity    //一定要用n的out下面的adb才行
                Verity already disabled on /system

还有要记得关selinux

1|ASUS_Z01F_1:/ # setenforce  0

在这期间还遇到了问题就是还是push不进去，于是看看目录的挂载情况

1|ASUS_Z01F_1:/ # cat proc/mounts

/dev/block/bootdevice/by-name/modem /firmware   vfat   ro,context=u:object_r:firmware_file:s0,relatime,uid=1000,gid=1000,fmask=0337,dmask=0227,codepage=437,iocharset=iso8859-1,shortname=lower,errors=remount-ro 0 0

原来是个ro也就是read only 所以需要重新挂载

ASUS_Z01F_1:/ # umount firmware/


ASUS_Z01F_1:/firmware #  mount -t vfat  -o rw /dev/block/bootdevice/by-name/modem /firmware  挂成rw就可以了

system里的fw主要在两个目录下

ASUS_Z01F_1:/system/etc/firmware # ls
