@Maurizio Finesso Try editing on a linux machine instead of windows. I've seen some windows machines not be able to read the boot partition

Moved to the correct sub-forum

This site deals with Armbian Linux not android. You should direct your question about restoring Android to a more appropriate forum

Please provide more information on what your are experiencing and what you have tried already

I just noticed from your screenshot that you aren't using Armbian. You need to ask support questions for non-armbian software from where you got your software. Ophub is a fork of Armbian that used the Armbian name without permission. They do not contribute to Armbian development nor do they contribute the these forums.

So you are saying that when you copy the working SD card install (by working I mean that it has the correct memory amount) to emmc that the problem occurs?

I am going to just point you first to the installation instructions on this site. What dtbs have you tried? What build are you using? What uboot are you using? This is important: have you ever booted anything other than the native android on this box? (Is so read the instructions about that). You really need to hook up a USB uart to get the boot output to understand what is happening. And if the button you labeled blue gets you to recovery that should be the button you want

Note that ophub is a fork of Armbian. They do not contribute to Armbian development nor do they participate in these forums or in anyway do they support Armbian.

Try a build using a newer edge kernel as a test

You can try different dtbs, different sdcards (older/smaller/slower = more compatible) and potentially a newer or older kernel. These failure to read the sdcard have been occuring more and more recently. No one has had time to reproduce and figure out the cause. I didn't see where you mentioned what build you are using, that would be helpful information

From what I see online that box has an s905 amlogic CPU

What settings have you tried? dtb, uboot?

Armbian does not support the s905x4

I don't think you understand how Armbian works. This board is community supported. It does not and hasn't been an Armbian supported board. Given the hundreds of boards out there Armbian only has the resources to officially support a handful. The rest end up being supported by the user community like this board. Thus support is only as good as the community volunteers who have the board and wish to volunteer their time to support it. Armbian provides the tools and infrastruction to make supporting boards easier, but the work still needs to be done by someone for community supported boards like this.

No it is not.

You are going to need to connect a USB uart connector to capture the console log of the boot. Without logs it is hard to know what is happening

Is your monitor a standard 1080p resolution or something else? If you try a server build that doesn't load a graphical interface does it work? Have you tried something more standard like gnome instead of cinnamon?

What exactly have you installed on the SD card (version, image name), and what steps have you used to install?

What you are reporting is quite common with tv boxes. The case markings often are different than the internals. What is it you are looking for? Your post didn't really ask for anything other than to report that you got a common tv box with internals that differ from the case.

You should also be updating your /etc/apt/sources.list.d/armbian.list as well (otherwise you will be mixing bookworm armbian packages with trixie debian packages)

First off, why do you want to? As the name 'edge' should imply, edge kernels are development kernels that are for testing purposes and may or may not work, and may break at any time. 'current' 6.12 in your case are LTS kernels that should be stable and more suited for non-development/testing use cases. If you do want edge kernels then you can use armbian-config to switch.

Lack of feature implementation, not a bug. 6.1 is the vendor supplied kernel where most things will work, but the vendor doesn't provide support. 6.12 is linux mainline kernel, where much functionality may be missing (as the vendor doesn't work to get their features into mainline linux, but relies on others (volunteer opensource developers) to do their work for them).

Per the install instructions on this site, if you have ever booted a different distribution then your box will be incompatible with the Armbian build. Although it is generally using coreelec builds that will do this. I don't know about the libreelec builds. Also you need to provide a lot more information about what you are doing. There are a number of steps in installing armbian on a TV box and you haven't specified any of the steps you performed. Finally debugging boot issues often requires that you find the debug serial console connection on the board and hook up a usb uart reader to get at the boot messages.

What download are you using? There is no meson-gxm-s912-mecool-bb2-pro.dtb in Armbian builds.
