I was trying to recover files from android phone using adb shell and test disk. But I am getting a read only filesystem error, even though the permissions to write is granted to the user.
adb devices
list the device attached.
After I ran the following commands
adb shell
Inside the shell I did the following
user:/ $ su
user:/ # adb shell "stty raw; cat </dev/block/mmcblk0p56" > data.img
sh: can't create data.img: Read-only file system
How to solve this?

Trying the proposed solutions:

You can try to remount the file system with read and write permissions (source):
sudo mount -o remount,rw /partition/identifier /mount/point
Or in your case you just can tray to redirect the output to a file located in a directory where you must be able to write:
adb shell "stty raw; cat </dev/block/mmcblk0p56" > /tmp/data.img

I would add 'writing to / is always a bad idea (not related if possible or not)'. But your suggestion to use /tmp covers the solution already.

Hi, @LupusE, why it is a bad idea?

There is something called FSH (en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard) to define what data should be stored in which directory. ... It is very important if you've got different partitions for different purposes. For example: Avoid to put /var/log on a flash storage. Much read/write will kill it ... It is the same if you store everything on C: in windows. Maybe good for the moment, but don't show anyone.
