A backup of LibreELEC only consists of the several folders in the /storage partition. It does not handle the files on the system partition.
If you want to upgrade/downgrade, place the file in the .update folder and reboot.
Thank you for the information but I do not find this folder. I use File Manager in the Kodi settings. Is there another way to access to this folder?
It's incredible, if I install LibreELEC 8.2.5 it works without problems.
Once turned on I tried to restore my backup (9.0.2) but after the restoring process the version has not been upgarded and stills on 8.2.5.
I tried two different monitors directly connected to the Odroid, two different HDMI cables, several microSD and eMMC cards unsucessfully
LibreELEC, CoreELEC and Ubuntu 16 do not works but Ubuntu 18 and Ubuntu 20 correctly works. It's crazy!!!
I also start thinking that it's a very strange hardware failure...
Anybody home?
After some changes on the Multimedia equipments at home Kodi don't starts on my O-DROID C2.
During the startup you can see the LibreELEC 9.0.2. logo as usual but later the screen becomes dark and you only see a black arrow on it. As I have a Logitech keboard connected I can move the arrow around the screen but that's all. Kodi never runs.
I formated and installed again LibreELEC 9.0.2 in the eMMC card unsuccesfully. Later I released the eMMC and connected an microSD with a fresh installation of LibreELEC 9.0.2 with the same result so, unfortunatelly I suspect that can be a hardware problem.
Any idea? Can I do any additional test?
Thank you!
I have had similar problem in the past and the reason was a device connected to another HDMI TV input. It was a Sony PS2 console with an HDMI converter that was damaged. It seems that the damaged converter interfered with the HDMI bus and this avoids to correctly detect the CEC.
Try to connect only your Pi4 to the TV and disconnect any other device on the others HDMI inputs.
Are this installations made with OpenELEC back in the days ?
If they were made with OpenELEC it is likely that your partition is too small.
From the initial LE 7.0 onwards these partition is 512mb at LE instead of 256mb at OE.
No, first installation was made with LibreELEC 8.0 and partition size is 512MB with 370MB of free space.
Then download the image manually, and put it into the update folder.
I tried to send the file using Samba but Windows10 do not likes LIBRELEC and isn't possible to connect. High security levels for an OS that introduces new problems at each upgrade 
Anyway, this is another history...
Using my Mac I'm able to connect through Samba with SMB1 protocol but when I copy the file into the Update folder from the Mac it says that there were errors during the copy and the file is not complete. Indeed, file size on the LIBREELEC is 0 Kb.
I tried to acces locally copying the upgrade packet in the HDD connected to LIBREELEC but with the file browser I cannot find the \Update folder.
Next attempt will be upgrade through SSH. We will see...
AFAIK, there is no system partition size difference between LE v8 and v9, so upgrading should work.
Can you check if there are some leftover files/folders in the ~/.kodi/temp folder that somehow might interfere?
I checked and the temporary folder is empty.
I think I have got confused with another post, this is if you get a message there is not enough space to create a backup.
to see the backup folder, in storage, from there you can delete the older tar backup files to create more space.
try it
in windows explorer type in the ip address of the device
sorry
I'm sorry, you're right. Before editing the original post I inquired about this, but as finally I already solved the issue by the "adding origins" function I deleted from the post this section.
Thank you for your concern 
Someone can confirm that to upgrade from 8.2.5 to 9.0.2 a fresh install is mandatory?
Will be possible to restore a backup from 8.2.5 later?
from windows explorer, you might be able to see it. personally, I use coreftp lite
To see what? ¿?
Many thanks Da Flex, at the "Update channel" I see the different versions and I have choosen 9.0 (MR) but the Available Version tab is empty. 9,2 is also empty and 8.0 shows 8.2.5. I upgraded to 8.2.5 sucessfully but 9.0 and 9.2 stills being empty.
How can I upgrade to 9.0 then?
Thank you!
Hi,
After 2 years enjoying LibreELEC without any change now I want to install the new 9.0.2 version as well as the new Kodi version 18.4
Actually I have LibreElec 8.0.2 and Kodi 17.3 running on ODROID C-2 hardware. Is there any easy way to carry out the upgrade or do I start from "zero" creating the microSD again and installing Kodi later? (frankly speaking I do not remember how I done this in the past 
)
If so, how can I copy the LibreElec backup and move to the new LibreELEC version?
Thank you!
Hi all,
I have Kodi Krypton 17.3 and LibreELEC 8.0.2 installed on an ODROID C2 hardware and although it works perfectly I do not see too much difference between the movies recorded at 1080 and the ones at 4K. I have the Kodi resolution set to 4096x2160p of course.
I'm sure that the MKV files are 4K but if I select the satellite tuner built into the TV (it is 4K) I can see the 4K channels with a perfect resolution so, the TV system fully works on 4K UHD. Even the football matches in DVB-T look better in 1080 than the MKV files played in 4K.
Can you think why it could be?
Thank you! 
SSH to the IP address of the box Accessing LibreELEC - LibreELEC
Thanks a lot chewitt !
It seems that to change some parameters on my Odroid C2 board I need to edit some system files and send some parameters using the Ubuntu's terminal mode.
How can I reach the terminal from LibreELEC / Kodi?
Thank you!
Nobody knows nothing about this matter? ¿? Amazing....
