I had trouble with Sergio’s instructions even after following them a couple of times.
I found the following instructions to work (by @Icon), and much faster and easier:
Continuing the discussion from Confiiguring Wifi on Apple TV:
This process took about 60 seconds in all, and worked the first time.
Cheers
Yup - can confirm - that worked perfectly!! 
Thanks for the heads up vanfog
Yes some of us had that working 22 days ago when I posted a hint and Soli posted up the commandline 
Some of you guys have no sense of adventure and are not persistent or experimental enough with a DIY, you may actually learn something as well if you play around.
Dumb question. Can you do this procedure to a working CB2 ATV1 without 1st doing the USB loading of OSMC?
I’m quite sure you can - you just need to be in a position to transfer the image over SFTP and to use SSH to invoke the DD command.
The only issue to be wary of is that you’re wiping your device and replacing it with the downloaded image, so your movie library, settings, addons, etc. will all be lost…
Well, I just tried this on an ATV running CB2. Uploaded the HDD image to the root of the ATV and ran the command:
sudo dd if=OSMC_TGT_appletv_20151123-HDD.img of=/dev/sda bs=4M
Where exactly am I supposed to upload the HDD image? This is what Putty told me:
root@crystalbuntu:~# sudo dd if=OSMC_TGT_appletv_20151123-HDD.img of=/dev/sda bs=4M
dd: opening `OSMC_TGT_appletv_20151123-HDD.img’: No such file or directory
root@crystalbuntu:~#
Thanks.
You would have downloaded the tar.gz file.
Did you extract this first before sending to the aTV? You have to transfer the IMG file inside, not the tar.gz file.
Copy that, it was extracted, it was the .img file, not the tar. Thanks.
I doubt writing a DD of OSMC_TGT_appletv_20151123-HDD.img, using an already running HDD installed version of Crystalbuntu will actually work without crashing the ATV1.
The OSMC DD image will overwrite the already running Crystalbuntu system files.
It has to be done from a external usb stick.
Sigh… guess I will continue to wait for the OSMC HDD install to get ironed out.
If the @vanfog 's steps didn’t work for you, like in my case (stuck in “Installing file…”) You can try followings. It takes extra time but it is technically more correct to not do “dd” on the same file system where linux is running.
1.) run osmc installer and prepare USB version with .img file: 2015.10-2-USB
2.) boot from USB and let finish osmc installation on the USB stick.
3.) ssh to apple tv (user:osmc pw: osmc)
4.) run following commands one by one:
NOTE:to download HDD.img file image you need also internet connection for your appletv
5.) remove USB stick and reboot appletv
6.) wait untill installation from HDD is finished
7.) extra hard reset might be needed if “appletv ?” will appear
8.) done 
Did the hdd install now, as described (by icon?). Fast and easy. Good stuff!
What free program do you use to ssh on Windows.?
putty
Make sure you upload the .img to the same directory you inhabit when running the command. /home/osmc/ for instance, which is where you are when you connect with ssh. I think. Connect with ssh, do “ls” and make sure the .img-file is there.
BAM! That’s it. I had my .img file in the root. Moving it to /home/osmc/ was the trick. Got both of my ATV’s running OSMC on the HDD now. Thanks bo1e, that was the missing piece of the puzzle for me.
This has got me thinking/wondering.
Can someone, maybe @vanfog or @elfnino , who has completed the “DD the HDD install image to internal drive” manual method… please post the contents of:
I don’t want to annoy my wife more than needed by wiping our ATV yet again.
