hi Portisch. i tried the new DTB in my Ugoos AM6B but it didnt quite work. However what i did notice is now the system LED option works, ie if i set it to heartbeat the led flashes red. this didnt work in the revised DTB supplied in RC3. So whatever you changed, it changed something, albeit, its still only working in red, no green or white colour seen on the LED.
The LEDs, nobody is happy with them. Everyone want to have itā¦ 
We have no information about this device and no support from vendor. So I am sorry and you need to use black ink or tape to fix it, thank you.

Just tried to (clean) install this version on my Khadas VIM3 for the first time. Up until now I was running 9.2.7 without major issues.
However I canāt get wired ethernet to work, Wi-Fi is fine though.
Iām using DHCP and sometimes CoreELEC shows connected with IP address 169.254.11.250 but my network is in the 192.168.178.XX range. My router also shows my VIM3 with the IP address 169.254.11.250 but itās unreachable. I already tried disconnecting/reconnecting and manually configuring an IP from the CoreELEC menuās but I can never establish a connection.
When manually configuring the IP CoreELEC shows me a wired connection with āstate: readyā and even my router interface shows the VIM3 as being connected with the proper IP but there is no actual connectivity. I canāt connect to CoreELEC from my PC and Kodi canāt connect to addon repositories either.
Is this a known issue with wired network in 19.2?
Downgrade Android firmware. On last images Khadas changed something about WOL and broke Ethernet support for linux, thank you.
Thanks for the quick reply! I decided to start fresh and āburnā (using USB Burning Tool) the latest Android firmware first thinking I would be properly up-to-date before installing CoreELEC 19.2. But it seems with Khadas youāre better off staying on an older Android firmware, last year they broke HDR switching with a firmware update for example.
Do you happen to know the latest working VIM3 Android firmware version?
To answer my own question: the latest working firmware is VIM3_Pie_V210128.7z.
Has anyone successfully tried to update Khadas VIM3L? It uses an SoC somewhat different from these. I am a bit intimidated to experiment, reading all the details that seem to be necessary. Or is it really not that bad to fix if this build does not work? Is there a recommended procedure of backup, etc written somewhere for me to study?
Can you give us more details about? Are you talking about Android or CE?
Umm. Talking about running CE on the device.
Is it possible to passthrough Dolby Atmos or DTS X audio to AVR? (Banana Pi M5)
Thanks for the response. I did a Kodi backup, then used krescue to do a backup of eemc. Krescue has an easy-to-use wizard that allowed updating to the latest CE. I used that, then restored Kodi. Everything looks like it is working fine. I then did another backup of the whole system using krescue.
I would like to move to the officially supported CE implementation, so I checked /flash. It now has a dtb directory with *.dtb files in it for a few devices. This does not seem like the CE standard install, so does this mean that I am still āunofficialā?
I am sure that this has been answered somewhere, but I am getting lost in all the details of the scattered posts, so I apologize in advance.
Kresuce is not supported by CoreELEC, please ask in Khadas forum.
Right, but my question is kind of the opposite of that. I am asking how to be sure that I donāt need to use krescue next time.
Please use the search function and read the links I posted already.
Krescue is a Khadas tool, not CoreELEC. So we have no idea what this tool does with the system.
99% of CoreELEC devices are able to make backup without Krescue, just read the links, thank you.
Install plain Android (probably VIM3L_Pie_V210128.7z) and then use ceemmc tool to install CE to eMMC.
Thanks. This is probably the right way.
Yes, itās possible.
The problem mentioned by the user with VIM3 is well documented in our side and last android breaks Ethernet. Did you update android in the meantime in your device? And please post dmesg.
I finally changed Coreelec 9.2.7 version for the last Matrix, but know i have a strange problem I didnāt have before.
When i always push backward/forward any movie, mainly those with higher bitrate, my box simply freeze and the only solution to āunfreezeā is unplug the power cable or with some luck remove the USB from the external drive and wait some seconds/minutes it goes back to the start menu. What Iām doing wrong or there a option in the settings to resolve this?
My installation is clean in another new kingston sdcard. And if it helps my log after the crash:
