Ugoos AM9 - SoC S6 S905X5

[SSC_Jarod]

Curious thing is, yesterday (after a few days off from home) I started the box, booted into CE and all files are playing like before. don’t know why and I am to scared to boot into Android in case it would do another or the same update. So I take my device, like before, from power source over a HomeKit switch and next time power on, so its boots every time into CE.

[Portisch]

Why you have set Playback 1 in CEC settings?
Default is Recording Device.

[rabaraf]

It is not changed. In “CEC client device mode” it shows “Recording Device”

I prepared new SD Card, installed the same last Nightly release, set EXACTLY the same settings in CEC settings as I have on the “faulty” installation and here CEC works, when selecting TV source and then back to AM9 source CEC is activating:

2025-12-10 14:49:06.847 T:1101    debug : CecLogMessage - >> source activated: Playback 1 (4)
2025-12-10 14:49:06.847 T:1101    debug : CecLogMessage - sending active source message for ‘Playback 1’

2025-12-10 14:49:06.847 T:1101    debug : CecLogMessage - << 40:04

2025-12-10 14:49:07.205 T:1101    debug : CecLogMessage - >> 04:45

Is it a CEC settings config file I can copy from “working” installation to “faulty” installation?

[EDIT] I restored Kodi using Backup app configuration from “faulty” installation to “new” installation on second SD and it work. I will keep it as it is, only what I need to “recreate” are ssh keys, crontab… I think it might have gone “corrupted” when I enabled “Dump display EDID” in CoreELEC settings in Hardware section.

latest AM9

Hello Sir,can I kindly ask you to enable Dolby vision playback on Ugoos AM9 PRO CE22,so I could get it working,thank you in advance.

[vpeter]

@Unlikeall3

Hello Sir,can I kindly ask

Yes Sir, you can.

[rabaraf]

I have 2 Ugoos AM9 boxes. On one of them as you can read above I had a problem with CEC eventually fixed by flashing CoreELEC on new SD Card.
On the second device with CoreELEC I see it is rebooting at random times directly to Ugoos Android OS.
It happened again last night at 23:36 (this is the timestamp on kodi.old.log)
In kodi.log and kodi.old.log there is nothing… just new kodi.log is created when I reboot to CoreELEC using Reboot_to_CoreELEC_5.0.apk installed in Ugoos Android OS.

I can see this clearly on Netdata monitoring on my phone:

Is there a way to catch what causing this reboot?

[Unlikeall3]

@vpeter

Yes Sir, you can

Alright then,let’s do it

[Wildpig954]

Hey Mate

I am looking on the official Ugoos website, all I can find is the Ugoos AM9, where can I get details for the pro version ? Please

[dror]

It appears in their 2025 catalog.

Everyone referring to this device, including Ugoos’ Telegram, is pulling their data from the catalog slide. The only other device there that is not in their normal site is the RockChip-based SK3.

It’s also unclear why the slide has LPDDR5 bolded together with Dolby Vision (but Dolby Atmos isn’t there, even though the chip should support it) - while in the spec itself the RAM is stated as 4GB LPDDR4X.

[Unlikeall3]

@dror

while in the spec itself the RAM is stated as 4GB LPDDR4X.

It doesn’t really matter what ddr number is stated,all it matters real world usage and the bandwidth,the am9 has total of 8gbps bandwith speed,while for a comparesment the everyone beloved nvidia shield 2019 has 6.80 gbps bandwidth speed(yes I kbow it is 6 gears old),so it could be ddr5 ddr10 or whatever,but only proper test could show real picture.

wondering if anyone else encounters this too? Could this be because of the last android update? that was the same time when the problem starts iirc. There was a popup in CoreElec i should update the firmware to get the “best experience”, thats why i updated android. Will see if i can downgrade (from 2.0.4 to 1.2.0).

I have only a linux workstation, no windows. Assume its required to have windows to downgrade this thing. Anyone an idea if its somehow possible to OTA downgrade with the zip? Where can i get that firmware zip?

[dror]

Didn’t say it matters. I was just pointing out the inconsistency in Ugoos’ own marketing material - especially since for some reason they emphasized the LPDDR5 more than anything else but the model name.

[rabaraf]

Yes, latest android firmware 2.0.4 is the root cause of this issue.
If you would scroll up you would find these reports:

Ugoos AM9 - SoC S6 S905X5

Hi @allall. Does someone have since nightly 4.12. and the one before problems to play a movie/tv content? After the update if I want to play any .mkv files from library or via filemanager, it takes a long time to start and I got sometimes the CE Boot Logo for about 2-3 sec. and hear the sound of played file and sometimes I see only the library but it doesn’t switch to the played picture. BTW: I did on Android side a update from the firmware that showed up yesterday, could this be the reason?

Ugoos AM9 - SoC S6 S905X5

Yes, definitely this is the cause: AM9 firmware upgrade to 2.0.4. I have 2 AM9 devices both running the same CoreELEC and on one of them I just did AM9 firmware upgrade and then see the same result: mkv files doesn’t play. Now the question is how to rollback [Update] Downloaded firmware 1.2.0 from Download Center, renamed it from AM9_1.2.0.7z to AM9_1.2.0.zip, selected as to file to perform firmware update and… after few minutes “update failed” Repeated action and now it stuck …

Ugoos AM9 - SoC S6 S905X5

Seems latest AM9 firmware has some changes which doesn’t works correctly with CE. Investigation continues.

[tete]

thanks, that confirms it… crap. do you have any idea where i can get the .zip so i can OTA downgrade?

[rabaraf]

Download Center

Be careful… Here is my story how I was facing difficulties with firmware downgrade:

Ugoos AM9 - SoC S6 S905X5

Did not found any video on YT or manuals on CE wiki how to flash fw particulary on AM9. If you know such tutorial paste the link. I tried USB Burn Tool 3.3.4. Can’t make it to detect my device. I tried many combinations with using Recovery hole, booting into Android Recovery (here it is “Return to previous firmware” but it says “Firmware not found" and no way to select img file on SD inserted) booting into bootloader, entering to fastboot mode… in all of this modes box is not detected in USB Bu…

… and I don’t think it is possible to perform firmware flashing via OTA…

[tete]

that means i have a “bricked” device until i get a windows laptop, perfect…

seems like there is a .zip available at firmwaredrive.com for the 1.2.0 OTA, but they want money for downloading.

update: settings → reset options → reset to 1.2.0
i am just doing that, lets see what happens
yay, worked…

[Portisch]

Why? Support for 2.0.4 in CE was add last week already?

[tete]

with 2.0.4 i was unable to play any video, it works with 1.2.0. youtube, netflix, iptv livestream, nothing worked with 2.0.4. now i am back at 1.2.0. disabled automatic updates and video works again

[tele]

I can confirm this. It is not possible to play files with CE if
firmware 2.0.4 is installed.
