Make sure you are holding in Recovery Button
Not Maskrom Button
There are 2 easily can miss
How long are you holding Recovery Button? Sometimes you need to hold it pressed for about 20 seconds before CE screen shows => press Recovery Button and hold it → power on the box → hold button pressed for 20 seconds or until CE screen shows, when you can release it…
I am surely missing something but I seem unable to use ceemmc to create a backup of my current installation on a USB disk.
I did it in the past without problem, now I simply wanted to update the backup to a more recent state of the machine and I am unable to do so.
I start the machine, it boots from eMMC. I insert the USB disk. The USB disk is “seen” in Kodi, from File manager.
I ssh to the machine, use ceemmc -x and I am presented with the usual options.

Make a backup of CoreELEC data on the flash partition of eMMC?
The “SD or USB device” free space is not the USB I insert. That disk is 16GB…
Those 19GB are the internal eMMC available space. And, in fact, the same options are presented if I don’t insert the USB disk.
But the USB disk is “seen” by the system. It appears in Kodi’s file manager, for instance.
Does CoreElec supports PCM 5.1? I have a mkv video which doesn’t sound when using CoreElec/PM4K. It sounds when using Firestick/Plex
Yes, it does.
Ok, so the corELEC should come up after it does the updating screen? That’s the first thing that comes up, I’ll have to get another USB drive to test. I thought that meant it was installing coreELEC so I let go when it came up.
Do you think I’d be better off opening a different discussion for this? I’m not sure if this is Ugoos related or not.
What could be wrong that there is no sound when playing the movie with CoreElec/PM4K, but does sound when using Firestick with Plex?
I wasn’t holding it in long enough - it needs another 5-10 seconds after saying upgrading.
Using Ugoos AM6B+.

But the USB disk is “seen” by the system. It appears in Kodi’s file manager, for instance. And it’s the same USB disk where I had previously used ceemmc to create a full backup (and a working one, as I used it to setup a new machine too).
Do I need to keep a USB stick in to use corelec? I completed the install, but if I remove my usb drive and reboot, it books back to Ugoos - is there a way to have it boot to corelec by default?
Yes
Need to keep USB Stick os SD Card in if booting from external media.
Or use CoreELEC Tool ceemmc-x and write to internal.
Yes, there is: coreelec:ceemc [CoreELEC Wiki]
Your case would be #1, CoreELEC not installed to eMMC.
By launching (from ssh terminal) ceemmc -x you start the process, then you just have to pick the correct choices.
On Ugoos you have to use Dual Boot Mode, you cannot have Single Boot. But, at that point, the machine boots by default to CoreELEC and you can then decide to boot to Android from inside CoreELEC (or never see Android again, ever).
Could somebody be so kind as to try and check whether ceemmc is still capable of doing full USB backups on latest nightlies?
I want to understand if it’s just a problem of mine or if it is widespread.
It’s option 6 after launching ceemmc and then you should be given the option of saving stuff on the external USB key (as opposed to internal storage, which is what happens to me, as described above).
Thanks in advance.
It should work as always.
I ran that command and chose dual boot, but it default to booting into Ugoos, how so I change it to corelec?

A backup of the selected CoreELEC partitions where done!
I selected ‘n’ because I don’t want to have a backup on local storage, I want it on my USB disk. Tried this on both USB ports.
Anything worth checking to understand why ceemmc does not “see” the USB disk being there (Kodi sees it just fine in File Manager).
Need to wait for someone more knowledgeable than me, as the procedure you followed should just work…
