[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] ulriktdc:
Okay so I'm trying to recover all the images on a Samsung Galaxy Tab Pro,

by following this guide Because there is a lot of pictures on it, that has to be recovered.

So far I have done everything the guide told me to, with some small changes.

First of all I found out that I have to use port 5037 instead of 5555 in this code line:

/system/xbin/busybox nc -l -p 5037 -e /system/xbin/busybox dd if=/dev/block/mm

Because if I use 5555 i get the "Address already in use"

And I only get access if I use 5037 instead.

Right now I'm stuck at step 6 in the guide. First nothing worked, I didn't get any progress, and the byte data was 0 all the time. Even the timer didn't begin to count the time. After some research in the guide i found out,

that I had to use ncat instead of nc

When I use this code line:

ncat 127.0.0.1 5555| pv -i 0.5 > mmcblk0p12.raw

This means the timer is counting now. But still no progress, except after a 2 - 3 minutes I get an error telling me the file or directory doesn't exist. The guide say that I maybe have to use another mmcblk, I tried a few, same thing. Therefore I tried to use this:

ls -l /dev/block/platform/*/by-name

And got this:

lrwxrwxrwx root root 1970-01-01 21:14 userdata -> /dev/block/mm

Now my question is, whats next?

I hope to find the lost pictures on the tablet, but I'm not sure what to do.

I can see the the info about userdata is; /dev/block/mm, but it's the same thing like the others I have tried..

Yes I did root the tablet, and yes "BusyBox" and "adb shell" have Root access

Everything is like it should be, but still I'm stuck.

What I'm I missing?
