Hi, i have Ugoos AM6 plus (not B), and when i try CoreELEC-Amlogic-ng-dv.arm-20.3-Nexus-Generic.img or CoreELEC-Amlogic-ng-dv.arm-21.0-Omega_beta2-Generic.img, (dtb for AM6) from SD card so first boot is all OK then auto reboot and fails to start, freeze on list of info or Coreelec logo. When use not dolby vision so this is ok. Is Ugoos AM6 plus not B supported? Or where is problem. Thanks for info.

reahcsa I have exactly the same problem on uGoos X4 Pro which is also an S905X4 box. SO assume this must be a known bug but wondered if there is any feedback form your post as not seen one. I am now reverted back to 20.2 -ng but it is an annoyance on each bootup to keep having to say NO to downloading the latest 20.3 update.

Interestingly I believe the Tanix X4 box uses Android ATV and I have patched my Android on my uGoos X4Pro to ATV also as I need that to be able to run the version of the Digital Concert Hall that is able to play ATMOS content as the normal Android box mobile version cannot play ATMOS from this app. All has been fine with this and with CE 20.2 until this 20.3 update. So is it maybe incompatibility with ATV.

Always I find Android causes problems and I have never liked that OS ever and why I have an iPhone too.

All you did a clean install without restore a backup?
As written it’s highly recommend as user space changed from arch arm to aarch64.

42

Not sure if this was a reply to myself and reahcsa. Anyway, yes after the auto update left me unable to play any videos as mentioned by reahcsa I then tried a fresh install on an SD card and got it to reboot no problem. Then I restored my backup of my suite of addons and the same problem was there. Even YouTube does not play videos and neither does any addon including Google Drive streamed files.

A local friend has the uGoos X4Q Pro with the default Android and since the update to 20.3 he has the same problem so I had to talk him through reverting to 20.2 and he is now back fully working. I have told him for now say no to the 20.3 update being available. So clearly it is nothing to do with my changing Android on my box to the ATV version which I believe the Tanix X4 has by default.

43

So what else is missing?
Just install addons on a new install, solved.
All binary addons like type of PVR will be broken after update to 20.3!
Just remove all, keep user settings, install again new, done!

Hey Jaffa,

I have the exact same issue on my Ugoos AM6 plus (not B).
(but B revision according to clock speeds based on Ugoos AM6Plus coreelec topic:
Ugoos AM6 Plus - #4 by boot2k3)

Did you figure anything out yet?

Thanks :slight_smile:

UPDATE: I figured it out! I let the long-not-updated Ugoos to update to the latest 0.5.4 firmware, and now it booted with am6 dtb on amlogic-ng-dv.
So I guess some changes in the firmware were needed for it.

Hi Fera,

I have Ugoos AM6 plus rev.b but not newer model AM6B. From the beginning i use coreelec, so android have stock firmware 0.3.9.1. Yesterday i tried update to 0.4.1 (Coreelec dv not boot), then to 0.4.2 (Coreelec dv not boot) but not try to newest 0.5.4. Tomorrow i will try it and i hope coreelec boot correctly.
Thanks

How did you update it. Through android update?

46

Back in the year 2022 I downloaded it from

and then installed it from Ugoos Settings Check Update or the box can check to see if an update is available and download and install.
I can’t believe you guys didn’t update it, everything was so much better after installing 0.5.4…

47

So i updated my Ugoos to firmware 0.5.4 and now Coreelec with dv boot correctly. I did not update before because i use only coreelec.
Thanks

Thanks for clarification Portisch and I was hoping that was not going to be the case. Updates within a generation of CE should IMHO be fairly seamless and just fix bugs and add new features that do not affect existing addons, But do not get me wrong here as I totally appreciate the fantastic work you guys do as a labour of love…

It is usually a lot of work to have to completely make a new build of addons and repos from scratch. Took me ages last time I did that. Many friends here I have set them up with CE20 and they are not techy enough to do that so best they stay on 20.2 I am thinking as I may well do myself. I will just disable updates until we move fully to Omega CE21

What advantage does 20.3 really give me over 20.2?? I am personally not bothered about DV as HDR10 is fine by me and not worth all the work if that is the only real small benefit for me. I will wait for a full release of 21 before I make a new build from scratch.

If I can simply restore my existing backed up set of addons and then uninstall and reinstall them then that wont take too long as long as I do not have to find and reinstall all the repos again, I can copy over the Addon Userdata easily enough or just leave them as is when reinstalling the main addons. Otherwise as I say I am happy to stay with a perfectly good working 20.2

Read the change log of CoreELEC ,LibreELEC and Kodi. Then you know if it brings some advantage for you. This arch step was necessary for future support of vendor kernel.

Not sure if I’m doing something wrong, but I have some Bluetooth issues in CoreElec running on a Ugoos AM6b+.

In the Ugoos I am able to successfully pair my remotes. No issue and both remotes (Ugoos and old Shield Pro) work well.

However in CoreElec, none of my Bluetooth devices are remembered. Each bootup I need to manually repair each remote. Most times I get an authorization errors here, and need to proceed with the LG remote. How do I fix this issue?

Make a journalctl | paste log BEFORE starting any playback!

And also:
systemctl status opentee_linuxdriver.service -l --no-pager | paste

If CoreELEC is installed internal flash Android again with USB tool and try first with with external boot media.

What about

source /etc/os-release
cat /etc/os-release >/tmp/peter
echo "COREELEC_DEVICE: ${COREELEC_DEVICE}" >>/tmp/peter
[[ "${COREELEC_DEVICE}" = "Amlogic-ng"* ]] && echo "Amlogic-ng" >>/tmp/peter
grep -q "sc2" /proc/device-tree/compatible && echo "S905X4" >>/tmp/peter
paste /tmp/peter
