respect to the team and the comunity which contributed to these LibreELEC RK222x builds.
Long story short:
I purchased recently (by mistake) a cheap TVbox labeled "MX10 MX Box S - 4K Ultra HD set-top-box". The scope for which I'm using it is mainly to playback videos from external HD's connected via USB.
Because on the original OS (fake Android 13, actually Android 7) Kodi was not able to playback smoothly 1080p videos, I searched for alternatives and landed at LibreELEC.
My problem is that the Le11 versions do recogniize my USB-HD's but the Le12 version doesn't. My HD's are nothing special but normal WD-Elements connected via a 4x USB3 hub.
What I did up to now:
1. Tested LibreELEC [unofficial] Le12 on SD card and it didn't recognize the USB-disks. However, with the latest revision dated 2025-02-18 the WLAN is working, but not the USB.
2. Tested LibreELEC [unofficial] Le11 on SD card and it worked: have LAN, have USB, playback is perfect. Don't have WLAN and file manager functions in Kodi don't work.
3. Backed up the original firmware with rkDumper (under Win10) and MultiTool (from SD card). Tried to extract the DTB's from the img files with extract-dtb v1.2.3 (python/Win10), but I'm not sure if i did it correctly.
4. Flashed LibreELEC [unofficial] Le11 to the internal memory, and it worked same as from SD card, but much snappier.
Remark: If you think it is helpful, let me know and I upload the extracted DTB's or, alternativelly, the IMG's which do contain DTB's.
Strongly hope that you can fix the USB problem, enabling me to upgrade to latest Kodi 

And here is the picture of the upper side of the board.
Thanx
