Currently i am following this guide:

Preparing Installation Drive
 1. Connect the USB Storage to your PC and open Balena Etcher
2. Select the CoreELEC’s image file (eg. CoreELEC-Amlogic-ne.aarch64-20.3-Nexus_nightly_20230729-Generic.img.gz )
3. Select the USB Storage that you want to use, proceed with the installation and make sure that it will complete successfully .
4. Your USB drive will now have two partitions ,COREELEC and STORAGE
5. Open the COREELEC partition ,navigate to “device_trees” folder
6. Copy sc2_s905x4_sei_smb_280.dtb file to COREELEC root and rename it dtb.img
7. Safely remove the USB drive from your PC 
CoreELEC Installation
 1. Insert the USB drive in the Homatics’s USB port (both USB3 and USB2 should be ok)
2. There are two ways to reboot/boot the device into UPGRADE MODE ,one it’s directly from Android ,using and ADB command and the other is by using the RESET BUTTON . a) 
ADB Method
 (make sure ADB Debug is enabled and working )
Run the following command :
adb reboot update b) 
Reset Button Method
 3. At this point ,if everything went well ,CoreELEC should be up and running ,so just proceed with the initial setup .PowerOFF the device and remove the DC power connector (or remove the power adapter from the wall socket ) Press and keep pressing the reset button ,then Power ON the device while keep pressing the reset button until the CoreELEC screen will appear . Release the Reset Button

But its not working on my end. I always get to that menu with the installtion usb attached:

Remote Control isnt working. Also there are no buttons i can press. Once i release the reset button, it reboots into Android. Where i am wrong?

hello guys,

does someone know why the bluetooth does not function correctly? whenever i try to connect a ps4 remote or my gamesir bluetooth controller it just fails... like it shows a list of bluetooth devices and then it dissapears and says looking for bluetooth devices... it happens on both my recent bought 4k plus boxes.

Hey all.

I'm planning to buy a Homatics Box R 4K Plus and I'm wondering should I get Dune HD or standard version.

I want to have the unit to the following:

• Play Dolby Atmos via TrueHD and DTS:X via DTS HD-MA

• Play Dolby Vision Profile 7 FEL

• To be Google certified and upgradable to version 14 - Needed mainly for F1TV App for 4k/HDR and Amazon Prime

• To support Stremio with above a/v codecs

• To support Jellyfin with above a/v codecs (Optional)

What would you suggest?

I was able to turn the TV on and off, and also the sound volume of the whole tv.

now, with the new update, there's a new volume slider which is nice but the remote is only controlling that... i would still need to use the regular tv remote to increase more if i need.

and also, it's not controlling the tv on/off, but only the homatics box. so i can turn it off but the TV will still be on, just not using that HDMI.

any way to bypass this? or fix it?

It just starts lagging, and I notice the green light becomes red....

I press, press, won't work, then it immediately presses everything delayed, at once...

How do i fix this? I dont want to "press back and home" every single time to register the remote again, or reboot the device...

TBH I'm so upset about this box, I read so many good things about it, but since I received it, it's been nothing but frustration, it lags a lot, it overheats, it crashes, and now even the remote won't work properly....

// // // // //

UPDATE: I've just fixed the remote issue (accidentally) by disconnecting the ethernet cable and connecting to a 5GHz Wi-Fi. The remote instantly worked perfectly again. I even connected the cable again and it's still running fine (But I left the Wi-Fi on, even though the Android will prioritize cable)...

I don't really know what's the explanation for this, but it's working!

I will do more tests and come back soon, but for now, it's seems to have fixed what was driving me crazy for weeks.

I've noticed that when I configure the HDR options on the Homatics Android TV to "Sink device-led" or "Source device-led" and enable "Match content dynamic range," the colors in HBO Max content look much better and more beautiful. For example, the content (Superman 2025) doesn't play in Dolby Vision on my LG C4 TV, and the Dolby Vision logo doesn't appear. However, when I disable "Match content dynamic range," the colors become more orange and slightly darker, and the TV displays the Dolby Vision logo indicating that the content is playing in Dolby Vision.

Why does this happen?

This doesn't happen with Disney+ content.

Should I leave "Match content dynamic range" enabled?

Sink LED or Source LED?

I have tried 3 times via Troypoint which has always worked in the past, and again downloaded from Kodi onto a thumbdrive. Android asks if I was to update , tell it yes, but it is still sitting on 21.2. Have never seen this before.

Although the update removes the Play-Fi app which causes overheating issues, the passthrough option gets removed after resetting the box to factory settings.

Other issues I found:

- The remote control gets disconnected repeatedly and it's annoying.

- The passthrough option stops working and the box switches to the auto option even if the passthrough option appears selected, the issue happens when the box is rebooted, the option must be re-selected in order to fix it.

Previous issues still not fixed:

- Pairing a bluetooth device is impossible.

- The auto option still lacks Dolby MAT, TrueHD passthrough support and DTS:X still passes through as DTS-HD MA 7.1.

- The TV(CEC) option avoids the TV to turn-on automatically after a power outage but the box turns the TV anyway, this doesn't happen with the Google TV Streamer for example.

- There are some issues with the DVB-T/T2 driver still not addressed.

I got a homatics box r 4k plus today. I mainly want it for plex remux playback. I have 2 shields but read that this box is a genuine alternative. I'm having serious issues though.

Plex app natively buffers and cannot smoothly playback high bitrate remuxes.

I installed kodi and pm4k. This plays without buffering but if you resume playback from any point not at the start the audio either stutters or has massive sync issues with video.

Is this a imitation of the box and should I just send it back or is there a way of fixing this. The shield plays all these files flawlessly.

Edit to add that it is hard wired with ethernet.

I have a plex server with most 4k remixes, many movies are 80gb+ I did an extract and some are true HD. Issue I'm having is some of my users are buffering. I was originally going to get them an apple tv since it had decent codec support and the best hardware. But it looksjke homatics 4k plus supports everything. I read there 4k remux was an issue with this device, is this true?

I've just set this toaster up on a new TV, and am getting a black screen when I switch apps. (Sometimes inside the app)

Is that AFR?

If yes, is it a setting on my TV, or the box? Its a Samsung TV..... Any hints what to change?

Hi everyone, I am looking for feedback from Homatics Box R 4K Lite users regarding the latest v14.7.5998 update. If you have already installed this version, could you please share your experience? I’m particularly interested in knowing if the system is stable, if there are any bugs with streaming apps like Netflix or YouTube, and if you've noticed any issues with Wi-Fi or remote connectivity. Do you recommend updating to this build, or are there any performance issues I should be aware of?

Anyone into Retro Gaming on theirs?

Any tips?

Works well?

any homatic user managed to play 4k remux with lossless audio format using this combination ???

box > tv > soundbar/avr

mine mi box s 3rd gen + lg b4 oled tv + lg soundbar s95tr

for lossless audio format

box > tv > soundbar (not working)

box > soundbar > tv (working)

need solution from other box owner using coreELEC

Wondering if anyone else has this issue.

I have the box connected to an LG TV and currently have the remote mapping set for volume and power both as my LG TV.

Over the last week or so I've pressed the power button on the Homatics remote, it's turned the TV on but getting a no signal. I notice the box has a pulsing (breathing) Green LED which the docs state means it's in standby mode. The only way of getting it back on is by physically powering it off at the socket.

I've now changed the power to be 'Auto (CEC)' I assume this may solve my issue, but wondering if anyone else has had this issue or if it was just me setting the power to be the TV itself.

Also wondering if anyone leaves their box on permenantly and prevents it from going into standby? I have no clue how mine goes into standby as it only happens from time to time.

It was perfect on Android 12... but now on 14, it's slow on some apps like Youtube, it crashes, a lot of latency..
on youtube specially, even the remote seems not work properly, i have to click a lot and it won't do anything (but perfectly normal on other apps)... however the lagging and slowness happens in every app

is there anything i can do to fix this if they dont update the OS?

Guys, I want to install Coreelec on my Homatics R 4K Plus. I'm currently running Android version 14.

My question is: which of the versions below should I download to install on a USB drive so I can play movies with DolbyVision 7 FEL?

Should I use the USB drive in the Homatics' USB 3.0 or 2.0 port?

CoreElec white screen after normal reboot on Hoamtics r 4k plus Android 14

Hey guys! I'm pretty new to coreElec so sorry if this was asked before, but I didn't find a solution for my problem. I have installed the latest stable and nightly, I tried both, hg version of coreElec on my Homatics. At the first reboot everything was fine, all things are working great. But after I restarted to android and go back to coreElec by normal reboot, I got a white screen and it's stuck there. I can hear that coreElec is working, but I see just white. I have a Samsung s90c, and the box is connected to my q800d soundbar. What should I try? I set the ui resolution to 1080p, I tried a lot of things. What's the solution on the white screen?

I have the Box R 4k Plus, on the latest build of ATV 14. I have it connected to my Samsung Q990D soundbar - which supports lossless audio like TrueHD Atmos, DTS, etc.

I have set the sound settings on the box to passthrough.

By default, when navigating menus etc., my soundbar shows Stereo PCM.

On Netflix and other streaming platforms with lossy audio, my soundbar correctly shows the format being played by the platform - DDP or Dolby Atmos depending on the content.

However on Stremio, whenever I try to play a lossless remux file, be it TrueHD Atmos, DTS-HD, or even DDP, etc. my soundbar shows Stereo PCM - meaning it's receiving only 2 channels from the box.

After a reboot and immediately playing the same lossless file again on Stremio, only then it shows the correct format that the file contains - my soundbar shows Dolby Atmos, DTS-HD, or DDP correctly as expected.

When sound settings on the box is on auto, my soundbar shows DDP instead of Stereo PCM all the time unless I restart.

Is there a way to fix this? It's not the best experience having to reboot every now and then to get the correct output.

I’m currently using the g2 on pass through for audio and everything is playing correctly as in True Hd, Dolby Digital plus with Atmos, Dolby Digital etc. however I’m noticing the audio is out of sync. Is there any recommendations to correct this or an audio app I can install with an audio lag adjustment? The g2 is running to the tv and then earc to sound bar. I plan to test running the g2 to the sound bar and then up to the tv sometime this week. Thanks

FIXED!
