Android: ADB – Mount a filesystem read-write

Mount a filesystem read-write

Very often when you want to write files to a particular partition on ADP1, you will get a “Permission Denied” if the partition is mounted read-only.
To get around this, you need to mount the partition read-write. Typically this is done with /system partition

$adb shell
$ su
$mount -o rw,remount -t yaffs2 /dev/block /mtdblock3 /system

(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts)
