MX10 mini, 4G/32G sd card boot not working

[biemster]

Hi,

Recently I bought a MX10 mini 4G/32G. Although I noticed in the usual eastern shops that the mini usually only comes in 2G/16G, I thought I give it a try. I wish i didn't, because now I'm having a hard time finding firmware for it, and also I can't get it running armbian or OpenElec from SD.
I've tried all the dtbs in both the armbian and openelec sd card images from balbes150 , to no avail. Just a black screen.
I also obtained the dtb from the android 9 (4.4.159) that the box came with using termux and

dtc -I fs -O dtb /sys/firmware/devicetree/base -o rk3328-mx10mini.dtb

All I'm getting is a black screen, no sign of anything booting. The hdmi does not detect a signal at all.
Am I missing something, and is there a way of getting an early log to see what's going on?

thanks,
Lars

UPDATE: above process to obtain the dtb actually works, in post #35 (after some Portuguese took over this thread) I'm reporting some success booting LibreELEC with this dtb.

With such symptoms, only the UART console will give an answer.

This always happens, the moment I ask for help something starts working haha.
The android 9 sd card image for the rock64 actually boots to some recovery, which activates the hdmi and displays some menu on the screen. It's been a while since I worked with those tv boxes / sticks (pre device tree times), but this seems something i can work with.
I'll post my progress here further, but if someone can give me some pointers as well that would be much appreciated!

Hey Biemster, I have same box and haven`t found anything so far . Dou you mind sharing the DTB extracted? Not sure how did you do that. Will try to boot something on it.
Thanks

[biemster]

I extracted the dtb using the program device-tree-compiler, which I installed on the box in Termux using

pkg install dtc

Then the code in the first post reads the active device tree info from /sys/firmware/devicetree/base.

I thought I made some progress when the rock64 image was booting to recovery, but upon further investigation it seemed that it was actually booting the recovery from eMMC, which I still don't have access to.
I shared the dtb and dts, but they are not booting my images either.
Good to hear you're working on it too! Please report back here if you make progress?

I bought this box (android 9), but some apps detect root, know some way to bypass?

(One way can be root and hiding with rootcloack -hide root module)

Has anyone tested? Thanks

[biemster]

Mine did not come rooted, but that would be very handy indeed. Still searching for a way how.

[surfriderbr]

Still not able to boot any linux image on it. biemster how did you get into recovery mode?

[biemster]

In post #3 i put a link to the sd card image of Android 9 for the rock64, if you boot the box with an sdcard with that image it will boot into the recovery that is on mmc.

Diegowdi google has difficulty translating your post, are you saying you have stable firmware files for this box?
