S905X SoC Android 7.2.1 firmware - "Universal" no brand specific

[argotera]

I have the beelink mxiii ii and had the exact same problem with you. can’t say if it works with the other box you ve got, but this solved it for me:

"Error dtb magic: a!" when using ceemmc tool to install ng build to internal

EDIT: SOLVED: TL:DR: search online for firmware “HQYG-TX7-nikodi-20180104” , and flash it. Then follow standard procedure to boot coreelec ng and install to internal. This procedure may work for other s905x 2g devices as well. Full version the installation to internal fails because the bootloader is old and not compatible with ng’s kernel 4.9. Installing a newer firmware from a different device solves this problem. this procedure may work for other s905x 2g devices as well. As posted by…
