After I read some other discussion threads, I set bit depth to 12bit and color space to 422 in both Ugoos and Kodi/CoreElec. And now it has been stable for couple days and I can play HDR10 movie which I had trouble with. Anyhow, all 4K UHD is 10bit/420.
Another post in different thread also suggests that these SoC may need a break-in period, usually couple weeks to couple months. And the symptom may disappear. Finger Crossed.
There’s no break in period
I got another AM6B+ as backup, should be good for many years to come. 
Hi,
I am new here, not sure if this is the right section to ask.
My Ugoos with CoreELEC cannot connect to my Windows 11 shared folders. I am using LAN cable only and static IPs v4. Connection works for SSH Putty from PC to Ugoos. SMB is enabled, passwords turned off in Windows. Folders shared as usual by right clicking.
The thing is: my Windows 10 laptop with Kodi connects fine (same LAN cable same LAN config) and I can browse SMB and then the shared folders, so the problem must be this CoreELEC system vs. Windows 11.
Can anybody help me with this, otherwise I will not be able to use this Ugoos player.
If you updated Windows 11 to 24H2, you will have trouble like me. I am running Windows 11 Pro and when it updated from 23H2 to 24H2, it killed all of networked connections. Luckily, I could roll back to 23H2.
If you find the solution, you will make a lot of people happy.
Maybe something like this?

Thank you. Hope I can find this information when that horrible 24H2 finally gets pushed to my PC’s without my consent.
Try to use USER/PASSWORD
There are more ways to share files on the network, you can try out ezhttp ( GitHub - SegHaxx/ezhttpd: A minimal, lightweight, self-contained and easy to use httpd for sharing an entire directory tree. )
Very simple http server that Kodi can access.
Just put the “ezhttpd.exe” in folder you want to share and execute it. It will Share the folder and ALL subfolders in it.
If you got more than one folder to share or drive you can use the terminal in Windows do execute it with parameters like:
Example:
(Terminal 1 shares on Port 9999 the Folder Movies on Drive D: )
ezhttpd.exe -bind :9999 "D:\Movies"
(Terminal 2 shares on Port 9998 the Folder TVShowes on Drive E: )
ezhttpd.exe -bind :9998 "E:\TVShowes"
In Kodi Add the source as “Web server directory http”
Server Address: IP Adress
Port: Your chosen Port
Be aware there is no security whatsover by using plain old http, as sharing protocol ! And the Share will be read only on Kodi side. (That’s usually not a problem since Kodi only needs to read files from the share)
I opened up my AM6+ today to check the inside and replace the thermal paste/padding. This is a rough guide, id advise take pictures as you go along.
1.Remove the sticky black feet and keep safely, I found 2 screws under these but it may differ for you, also the other 3rd screw more easily seen
2.remove the antenna’s gold screws
3.Remove another 3 screws and remember these for the mainboard screws. Now you may need to wiggle the mainboard out since there still connected to the usb and other ports so a bit of wiggle and it should pop out easily, it it don’t check for other screws holding it.
4.Here is the mainboard, see the 3 white heatsink prongs you will need to flip the mainboard over to remove the entire black heatsink.
5.3 white heatsink prongs as mentioned above, gently nip them with small nose pliers to get them off.
6.heatsink removed
7.remove this thermal pad, they cheapen out here it was far too thick like 2-3mm and the contact between the cpu heatsink and cpu core was level flat. Id imagine the heat would not have transferred well or slower.
8.I use honeywell PTM7950, its about £8-12 thermal pads but shown to knock degrees off compared to usual thermal pads, also last forever unlike thermal paste which dries up.
New honeywell PTM7950 pads installed (remove thin film on both sides!) also added a 10mmx10mm by 3mm chipset heatsink with thermal tape on the chipset on other side.
Move the red/black wire around the heatsink, to prevent any melting/burning risk, it should never have been put in-between a hot heatsink really.
Check the cpu core is in contact with the new pads and heatsink, shine a bright torch and make sure no gaps. If a gap is there try another layer or 2 of honeywell thermal pad but lesser is better for better heat transfer.
My temps dropped maybe 15-25+c,. Overall its not 100% needed but I wanted to see if it helped with my hdmi signal drop issue and just see if I can improve what is imo the best kodi box going.
The quicker and easier solution if your AM6+ is getting hot, a 120mm usb fan or laptop style cooler can help keep it cool and improve longevity.
Thanks for your guide! I’m planning to do this as well.
Is there a burning risk if the AM6+ is idle/turned off? If that’s the case i’m going to modify it rightaway. Don’t want to burn down my house obviously.
Is the nightly build still recommended or is 21.2 stable good?
Stable 21.2 works just fine with DV etc.
Id say no risk with it being in idle, even more less to zero if switched off. These boxes consume very little electricity anyhow so I tend to just leave it switched on, I also disable sleep within setting/system>put display to sleep when idle to prevent any crashing.
There is no need to do this mod imo, but my box is a closed gap/space mounted behind a desk with little to no airflow, others may have put it in a closed cupboard or out of sight, also I am use to doing modding since I do similar with mini pcs and pcs in general.
Some users have a timer plug, so can set it to go off completely or the ones with a remote on and off, or you can just remember to shut down via the main menu>electrical plug icon top left under Corelec logo>power off system.
A better way actually is in CE Kodi settings/system>power saving>shutdown function timer and set to your desired time. So you can say 1hr, if it detects no activity after an 1hr it shuts down on its own.
Ok thanks a lot for the detailed explanation! Appreciate it.
Two Question - I bought the AM6 plus, not the AM6b plus, should I return it if I’m looking for DV playback (I’m on ethernet, not wifi)? Second which image do I use is the AM6 one compatible event though it doesn’t specify the plus model?
the only difference is WiFi 6 on the AM6B+.
Great, that’s what I thought - can I use the AM6 image since I don’t see a plus option?
All have the same generic image, but the dtb file is different.
So this file for your device without B letter.

Thanks. I down have my USB installer, when I held the recovery button in with the USB drive, I don’t get a corELEC screen, I get a box that says upgrading. Then it reboot over and over until I remove the USB stick. Then it boots in the standard Ugoos. Seems like the install must be failing?
