Howto: Backing up your DJI Crystal Sky System Image

This thread is for making a  system image file of your CS before installing a bunch of stuff or soft brick the booting.

Before you do anything else with your Crystal Sky make a back up of you system image file. If for some reason you should end up bricking it this will be the only way to recover it without sending it back to DJI!!!

@nocommie - lot's of patients there brother!!

First you need to root your Crystal Sky. If you don't know how to do that then check out this guide.


Second - you need to make the system.img file. You do this in an adb shell. If you don't know what that is go back to the guide.

Likewise, you need root access(in the guide too!). Oh, put an sdcard in slot 1 on your CS.

adb shell

Now get root going.


I like to do these commands at the root so do this command.

cd /

The command to get all of the system files into a system.img file is this.

dd if=/dev/block/mmcblk0p10 of=/mnt/internal_sd/Download/system.img

You should see something like:

root@zs600b:/ # dd if=/dev/block/mmcblk0p10 of=/mnt/internal_sd/Download/system.img
6291456+0 records in
6291456+0 records out
3221225472 bytes transferred in 68.097 secs (47303485 bytes/sec)
root@zs600b:/ #

The next thing you want to do is transfer the system.img to some place safe. Let's move it to that sd card so you can store it on your PC or NAS box.

While still in the root do this

cp /mnt/internal_sd/Download/system.img /mnt/external_sd1/system.img

Now you can take that system.img file and save it to your safe place.

I'll use this post to outline putting the system.img back onto your CS should you end up screwing it up so bad it wont boot the the DJI update screen.
