Well, it appears that the System Info IP Address is different than the connection address in CoreElec configuration.

Using the System Info IP address and FTP, I get a connection error and this message
"An attempt was made to access a socket in a way forbidden by its access permissions.
Connection failed."

I have absolutely no idea what is going on here
Make sure you also have the correct port number

If you see the images depending in the file protocol the port number is different.
You also can change the port number.

Your client (winscp) and you server (u9h) must have the same port number in order to work.
Dont forget to insert also the ip number, login and password correct in winscp.

If all that dont work disable temporarily antivirus/firewall in router/windows

Are talking about the 4K audio/video playback issues, or the verbose startup?

If you are talking about the startup, I don't really care UNLESS it is the source of the 4K playback issue.

I have tried many 4K video files now, and NONE of them play back without excessive stuttering and freezing. Audio also severely messed up with dropouts and serious sync issues. ALL of these files played fine under 9.0.2.
how about the color of the 4k movies? Are they washed out?
I have never had a 4k movies playing without washed out colors played by my minix using LE or CE.....

Color is very good. Although, depending on your TV settings, the color can vary quite a lot. If your videos are washed out I would check your TV's picture setting and see what effect changing them has on your color.

WinSCP changes the port setting when you change the protocol. I did not change the port setting. But how does one find out what port setting the U9H wants/needs?
 
Don't ask me why, but it suddenly started to work. Absolutely no idea what I did or what might have changed to make it start working.

Ok, so now to get to the reason I wanted to connect to the U9H.

The 9.0.3 update is a total failure for me as I can no longer play any 4K videos. I have a LOT of 4K video, so this working properly is a MUST for me.

I want to roll-back to 9.0.2, which worked flawlessly. I read in an earlier post that if one placed the *.TAR file into Storage/Update, when you rebooted the system it would pick it up and perform an update installation.

Ok, so now that I am in, I located Storage, but there was no Update folder, so I created on, then placed the 9.0.2 tar file in it and rebooted.

Nothing. Zip, nada, nyet, zilch. No update, just a simple reboot of the system.

So I would like to verify that information. I should be using the TAR file and not the img.gz file, yes?
And the location to store the file is indeed Storage/Update?
Is there a way to FORCE an update? Alternatively, is there a way to force a clean install?

Is there something else I should be doing? Am I missing something here?

Well, there's some issues with this last 9.0.3 version.

After upgrade from 9.0.2 HDMI CEC (Bravia Sync) stopped working auto-switching of HDMI ports on my Sony TV.
Interesting is that all my devices stopped auto-switching not just my CE tvbox.
Maybe because TVbox is connected to HDMI3/ARC port usually used by AVRs.
HDMI CEC settings are the same as before on older 9.0.x versions.
No other issues with the 9.0.3 version but this one is inconvenient

You can also try a nightly version...

Ok, thanks for that correction.

And it is the TAR file, yes?
Yes ;)

here is the manual update guide :
For updating CoreELEC while using the command line interface, you have to SSH 47 in, using username: root and password: coreelec and then move to the correct folder with the command cd /storage/.update

Once at the correct folder, the specific file can be downloaded directly to our device using
wget https://github.com/CoreELEC/CoreELEC/releases/download/8.90.5/xxxxxx.tar
(substituting 8.90.5 with latest version number and xxxxxx.tar with the correct file for your device).

If preferred, a previously downloaded update file can, of course, be transferred to the /storage/.updatefolder, using your favourite SSH software.
Once the update file is in the correct folder, reboot the device

The update process will start after that by unpacking and installing the update, followed by a another reboot.
 
UPDATE:

Since I got WinSCP to work, and since I had that update location wrong, I decided to try running CoreElec from an SD card instead. Then I got the bright idea to try 9.0.3 from an SD card. Well, long story, and pretty much a wasted day, I DID get it working properly under 9.0.3.

When I was initializing 9.0.3 on the SD card, I saw the CoreElec Driver Module and went in there to see what was there. It offers the choice of CoreElec default drivers, DVB drivers for TBS and DVB drivers from the latest (linux) kernel.

Since my upgrade from 9.0.2 was an OTA update, I never set or selected any drivers. But, at least on my system, it appears the DVB drivers from the lastest kernel is what was installed by the update. 1080 and lower quality video play fine, as did most (but not all) audio. 4K video on the otherhand was a complete unwatchable mess.

I clicked on install the CoreElec default drivers, and voila... 4K video now plays and without the audio issues previously mentioned.

So for now at least, my problem seems solved.

For anyone else who might be having 4K playback issues, check and make sure the CoreElec drivers are installed and not one of the DVB sets of drivers.

I also do other tests and you dont wasted a day, you gained a day, you gained knowledge ☺ . Next time you do a OS upgrade for example you already know how to do it ☺.
Thank you for sharing with us to help others.

The washed out color has nothing to do with my tv settings. The very same TV has a superb color when playing bluray movies, however when playing all 4k movies, the color is like washed out. No problem at all with Netflix 4k.
 
Washed out color is indicative of no HDR support on the video output device (TV). I have great performance with 4K - all variants 8-bit, 10-bit, and HDR running CoreElec on my U9-H.
This was the primary reason I bought the MInix U9-H to replace my Odroid-C - the 912 processor with HDR support as the HDR files are much smaller with great colors.

Not entirely ;)

I do not have a 4k HDR TV but i do have plenty of 4K HDR media ( ready for when i do get one !)

I run stock Android firmware on my U9-H and providing you turn on HDR in minix display settings the colours are not washed out. Yes they are a little "darker" as is normal with HDR but selecting a more "dynamic" picture mode on the TV they look superb (even on a 1080p TV)

I really dont see any need to run Corelec or similar on the U9-H to be honest.
