root@android:/# mount -o rw, remount /dev/block/system
mount: Read-only file system
来自adb：
C:\androidSDK\sdk\platform-tools\adb remount
remount succeeded
如果那时我尝试打开文件里面/ system是只读的。我有一个'irulu ax105'平板电脑。这是我目前的情况：
C:\androidSDK\sdk\platform-tools>adb shell
root@android:/ # ls -l
ls -l

以下为我工作
mount -o rw,remount rootfs /
或重新安装/system
mount -o rw,remount /dev/block/bootdevice/by-name/system /system
