I used the Reboot to CoreELEC (Reboot to CoreELEC APK) to install CoreELEC. Just make sure, under Android, you select “Enable developers options”, “OEM unlocking” and enable “USB debugging”. That works for me. Using Dune HD Pro 8K plus.
Keep in mind, the R3 or R4 remotes do NOT work under CoreELEC. I use the Ugoos UR02 remote, it is fantastic, and CE has drivers for IR and Bluetooth.
I’m sorry I was imprecise. I am able to boot from USB, was hoping to boot from eMMC. I used the ceemmc tool, but it won’t boot that way.
I was looking to have just one interface the Kodi interface. But it sounds like it may not be possible today. Sounds like I could just sideload the latest version of Kodi instead. Just means more learning for members of the household as they have to learn the DuneHD OS now to get to Kodi.
Actually I’ll check tonight perhaps it always boots to USB as primary after installation on USB. At least I can keep it that way.
Will take a look at Reboot to CoreELEC as well. Thank you!
Any disadvantage on running CoreELEC even if not necessary? For me I’m going that route because I like the fast boot to the Kodi interface.
Wow machine lists as $800 to $1000
Was reading specs on this Box from Dune HD.com
They claim when using Linux based Dune HD OS
Dolby Vision Profile 7 MEL and FEL Playback…
Apparently a Internet connection is required…
The idea of S928X-J/K SoC that can Playback FEL was most interesting 
Have you tested Both OS ?
Dune
ATV 11
Just got my hands on this. I can run some tests tonight (after I figure out how to write the Dune firmware back 
), what would you like to see?
Well would be see if there claims are true ,or false advertising
Dolby Vision Profile 7 FEL playback
What’s the proper way for me to validate that?
Have you Tested Dune HD OS?
Dolby Vision FEL playback?
You would need Dolby Vision Profile 7 FEL Test File.
Its not critical
Many times Vendor Specs are subject to limitations etc…
Run some FEL test files from here
Run “BL_EL.mkv” from that link, and at about 80sec you should see a woman holding a camera. If you don’t see her - NO FEL
Is there anyway to test the Dune HD OS for FEL playback, other than the lady with a camera clip??
Using that clip, it shows that the Dune HD Pro 8K Plus ( Amlogic S928X-K/J) does NOT support Dolby Vision profile 7 with FEL.
Even playing that clip under CoreELEC, it does NOT show the lady holding a camera.
Then you have no proper FEL playback. With any box that supports FEL (which I have tested - 6 of them on CE-NG) that test video shows the woman holding a camera after 80sec…
Iam only going by what i read from Dune website
Specs…all Dolby Vision profile playback VS 10 engine lldv ,TV LED Player LED etc…
Not sure what internet connection required means.
To good to be True
Will try to do some testing tonight after I recover my DuneHD OS boot and report back.
Thanks! Will try this tonight and report back.
I made the statement that the Dune HD media players did NOT actually support Dolby Vision profile 7 with FEL. Here is the response from Dune HD support.
"
NO Dolby Vison profile 7 with FEL
Dune HD media players support playback of Dolby Vision Profile 7 FEL and fully use most important information from the FEL layer - Dolby Vision dynamic metadata (RPU), and this allows you to fully enjoy the Dolby Vision effect when watching real Dolby Vision movies. The reason for these discussions about FEL on the Internet is the widely known fact that the Android SDK of modern media processors (RTD1619, S905X4, S928X) do not support the use of so-called “residual signal” from the FEL layer. There are test files which allow you to check if this residual signal is used or not. But the importance of this is very low or zero, see below for details.
DV P7 video files consist of two layers, BL (Base Layer) and EL (Enhancement Layer).
For MEL type Blu-ray discs, the EL layer consists of “Dolby Vision dynamic metadata” (RPU).
For FEL type Blu-ray discs, the EL layer includes two types of data: “Dolby Vision dynamic metadata” (RPU), and “FEL residual signal”.
As written in the product description, Dune HD media players extract and use “Dolby Vision dynamic metadata” (RPU) data from the second layer. This is the most important information that determines the essence of Dolby Vision technology (individual picture settings for each individual frame in the video, which allow you to see the very dark details in very dark scenes, to see very bright details in the very bright scenes, and to enjoy the best look of each scene). It works in full, no second HEVC decoder is required for this functionality to work.
The so-called “FEL residual signal” is intended to restore a 12-bit signal from a 10-bit signal. It is not used, but the significance of this limitation is small. All OLED TV models have only 10-bit matrices and restoring a 12-bit signal will not increase the actual displayed color depth, it will be 10-bit anyway. Whether the residual signal is used or not can usually be seen by playing specially encoded test files. Usually, to allow you to see the difference, these special test files are made as an incorrect combination of base layer from one video, and enhancement layer from another video, or are prepared in some other wrong way. During normal watching of real movies, properly encoded according to Dolby recommendations, you usually should not see differences. Most Dune HD customers report that when actually watching real movies, they do not see any difference between the Dolby Vision picture quality from Dune HD media players and, for example, from reference OPPO Blu-ray players, which perform full FEL decoding.
For most Dune HD customers, much more important is not this minor limitation, but the conveniences provided by Dune HD media players: the ability to watch DV P7 FEL movies in any popular formats (MKV, MKV, BDMV, ISO, lightweight menu, full menu) out of the box, without conversion, with excellent Dolby Vision quality with full use of Dolby Vision dynamic metadata (RPU), launching DV P7 FEL files from any media (local disk, SMB, NFS), correctly working rewinding, synchronization of audio and video, switching audio tracks and subtitles, loading subtitles from external files and from the Internet, and many other features."
Personally, I can’t tell the difference between FEL and MEL, etc. HOWEVER, I have been updating a lot of my DVD files to Blue-ray and a LOT of them are encoded with that awful VC-1 video codec. So, my priority is finding a media player that CAN play that codec without issues. I use my “Band of Brothers S01E01” as a test. Around the 8 minute mark, a fly lands on the soldiers neck and he slaps it. If that VC-1 is not decoded correctly (hardware or software), the slap does NOT match the sound. That means LOTS of skipped frames. Even my Dune HD media players using the Amlogic S928X-K/J can NOT play that codec.
Good to know! Thanks!
In short - NO proper FEL, only fake like, many others do
That’s a lot of bs marketing lingo to say FEL is played as MEL, same as Shield Pro/Homatics/etc. Dune has always been extremely deceptive with their wording on P7 FEL - intentionally trying to mislead consumers into thinking it is properly played back.
The 12-bit is still tonemapped into 10-bit, and there is a side-by-side difference demoed in many screenshots/YT vids. Especially on expanding brightness.
Thanks for info
Thats exactly was reading also
Got confused by all the marketing lingo
3 descriptive paragraphs…mention Profile 7 FEL like 10 times …
Side note
Upload Band of Brothers test file maybe
Will test on my X96X10 PRO S928X-J for VC-1 playback.
Have only one VC-1 tesfile someone here posted
It’s a Western …
Playsback fine
Dune and Zidoo have been false-advertising FEL support for a while now for S928X-based boxes, or even S905X4 on the Dune OS & Android sides.
Look at how Dune sneakily frames FEL–I highlighted the statement in question :)…
Dolby Vision profile 7 FEL
The media player supports direct playback of Dolby Vision profile 7 FEL double-track and double-layer files. This is the most advanced Dolby Vision format. The media player plays video in this format using both tracks/layers. The important Dolby Vision information from the second track/layer (Dolby Vision RPU metadata) is transmitted to TV together with video data from the first track/layer. The passed video data uses 10-bit color depth - the maximum color depth supported by OLED-panels in OLED TVs, i.e. this fully uses the capabilities of OLED TVs. Combined with the full use of Dolby Vision metadata this gives an excellent Dolby Vision picture on the TV screen.
What they really mean is the RPU metadata from the enhancement layer is transmitted to the TV together with the video from the base layer.
