How to Backup WeOS 3.2 on the internal eMMC in a Wetek Play 2?

Hi again,

before i install anything on eMMC i want a complete secure backup of the original WeOS 3.2 Android installed on the internal eMMC.

I can use:

Coreelec 9.0.1

LibreELEC-AMLGX.aarch64-13.0-nightly-20260404-b44d4f4-box.img

Armbian_community_26.2.0-trunk.668_Aml-s9xx-box_noble_current_6.18.21_xfce_desktop.img.xz

Which are the exact commands to identify and then backup the correct "drive"?

And how to restore it when needed?

🙏

Was this the right way?

it resulted in this:

The "Size" is exactly the same than with the wp2 image from here: RE: Wetek Play 2 issue with NAND

So i think all went right, or?

Is "mmcblk1boot0" and "mmcblk1boot1" good to have a backup too? both have the same checksum at the end.
