Factory Ugoos AM6/AM6 Pro & X2/X3 eMMC Dual Boot CE Unofficial

[lightsout]

Does the CE tool add the reboot to emmc option? And is the option to reboot to CE
also in Android? This seems like the main thing that is needed for simplicity sake.

[boot2k3]

In default CE skin you have this option by default.
In Android a logic will be different. After reboot you return to CE.

If you read it to the end then you will see a hint: ceemmc -x
…
All possible steps described in instruction

Thank you - yes, had seen that - the one part that is not clear from the instruction (just simply reading it in the guide) is how you execute the options - but it all becomes very clear once you in fact execute the initial command - it indeed lists the available options for the EMMC status it finds and then instructs to select from [1,2,3,4] and you simply enter the number and execute - I think that very last step could be added to the on-line instruction. Again, it IS obvious once you start, but adding it in the instruction would just be helpful to complete what to expect - it’s obvious in hindsight but looking at it beforehand it just wasn’t clear how the options would be executed.
Not a criticism at all, just a first-time user of the tool perspective.
And yes, it was indeed super-simple!

Yes, if you need to update android you could make CE backup or move all data via same ceemmc tool on USB/SD and after return back

It looks like you would execute option 6, then option 7 (two separate operations it appears) then option 1 again to re-install after the Android update
It’s not as much of an inconvenience as I perhaps initially perceived.

Nice job CoreELEC Team

@decosse

I just sent them a suggestion that if Dual Boot option is to be successful, they must make a larger partition available for CE (their reluctance might be from the std AM6 which has only 16GB)

@decosse

Received a very prompt reply back from Ugoos customer service - “I think our guys have their thought, may need some time to make that version better” - but nothing imminent in that regard. But would pass my suggestion/issue to engineering

I also challenged why use a CE nightly version for the basis? …

Dualboot build with CoreELEC

1. Increase CoreELEC partition size to 3GB
2. Replaced CoreELEC night build to stable 9.2.2

Looks like they listened to BOTH of my requests - now that is service!

However I’m not sure I will swap over to the full Ugoos Dual Boot firmware - now that I have the CEEMMC capability installed and both OS configured it’s actually much more convenient to use CEEMMC to update both independently (vs having to now burn the Dual Boot and then re-configuring my Android)

Does anyone know what the relative ‘lost space’ is for CEEMMC vs the Ugoos Dual Boot config? Are they the same?
(It’s actually not an issue for me - just curious)

[boot2k3]

CEemmc tool Bqeel Y8 MAX dualboot

No, the tool take the amount of Android data partition (maybe ~54GB) and the partition is shared with Android in dual mode installation.

Space is not lost…
You could check the space with command df -h

[decosse]

The disadvantage is that not all memory of the internal eMMC can be used. Around 5GB of the internal memory is lost in this mode because of the Android partition layout. The amount of lost memory depends on vendor/device.

This is the part that is confusing

[boot2k3]

Android partitions use some space that couldn’t be used in dual mode by CE. This is jist a comparison with CE single mode installation.

[decosse]

OK I think I follow
Have to say that note about the 5G ‘lost’ is very confusing statement and could be better clarified - just a well-intended constructive comment.
As written it gives the impression that when you install CEEMMC Dual Boot - you are going to lose a new 5G of unusable storage in addition to the CE requirement AND the Android system

So perhaps a better statement might be:
In a Single Boot CE installation, the Full Storage Volume will be allocated to CE
In a Dual Boot installation there will continue to be a reserve of approx 5G for the Android allocation, leaving the remainder available for shared storage.
