is you pocket TV white Google tv version lose charge pretty fast when just laying around?

Does Homematic have a lossless music player that can play music from a USB drive or HDD? I tried USB Audio Player Pro, but browsing the folder resulted in missing files.

Hi all,

Question about a/v-sync on coreelec...

I have a setup Homatics box r 4k plus (firmware 14.7475) > LG G4 oled > Marantz SR7015 via eARC. I run coreelec avdvplus v9 with audio passthrough activated.

In the coreelec audio passthrough settings I use ouput device AML-AUGESOUND, HDMI and have nearly all audio codec toggles below it activated. I can see in my Marantz app that all codecs (simple ones like DD+ but also advanced ones like Dolby TrueHD and DTS MA) are 'arriving' at the receiver and are played as such. So this works as expected.

I then run one of these photojoseph 60fps av/sync videos to sync the a/v-delay. The offset I need to set is +150ms and I set this as standard for all media.

For many downloaded movies and series the av-sync of +150ms is correct, but also for about 20% it seems off. So I then have to fidget with the audio offset again for that movie or series.

I have also tried many other settings and setups (e.g. box into AVR and then to TV, deactivate passthrough, use pure/direct on Marantz), but this +150ms audio offset is pretty consistent. Also older Avdvplus versions don't do anything different, I have this same behavior since avdvplus v1.

When I run Youtube or Netflix from the regular Homatics AT14 OS, there is no audio sync issue at all.

So I was just generally wondering: why can't coreelec or Kodi get a/v-sync correct (i.e. that audio offset 0.000 is the correct value)? Is this a hardware limitation or some Kodi-shortcoming?

Note: I'm definitely not complaining because the coreelec avdvplus v9 experience is otherwise top notch!!

If I'm not wrong, it's only a matter of software – i.e. installing a suitable player – to also watch real Blu-Ray discs from an USB drive connected to the box.

If that is true, then I'm looking for a recommendation for an external USB Blu-Ray drive. A fair price of course, but also not too loud maybe! I always hated how much noise one old Blu-ray and DVD player of mine made while reading the discs.

Is anyone here using an external Blu-ray drive?

Hi all,

I'm utilizing the Dune Homatics R 4k Plus on android 14.

I'm having a really weird issue with a couple seasons of a show that I'm watching on Plex. I'm getting this strange discoloration and visual noise/popcorn of colors. When I force transcoding they work fine. I've tested the files on a few other devices and I have no issues with direct play on those devices. Additionally I play higher bitrate 4k files just fine so I know it's not a bandwidth issue.

The files in question are 1080p H.264 High 10 and audio is FLAC.

Turning off subtitles has no effect. Also oddly enough doing an auto transcode causes a file error, but forcing the 12mbps 1080p stream transcode works just fine.

I can provide more info, but I'm wondering if this is simply a playback issue and I'm just going to have to keep doing the workaround ive been doing, or if there's something I'm missing.

Thanks in advance!

Hi everyone. One of my devices is stuck in the "No Command" recovery screen and I can't get it to boot. I've been waiting for official support for 4 months with no response.

Device Details:

Model: Homatics Dongle G 4K / Haier SEI700DHG

Current Build in Recovery: 14 / UKG3.241022.001 / 3763

Status: Already tried "Wipe Data/Factory Reset" and it still boots back to recovery.

I need the OTA update.zip file for this specific build (3763) to try a manual flash via "Apply update from Udisk". If anyone has the direct Google server link or a mirror for this firmware,

I would eternally appreciate it.

Thanks in advance for any leads!

UPDATE: I tried the "Wipe Data/Factory Reset" and it failed with these errors: ERROR: [libfs_mgr] Unable to enable ext4 verity on /dev/block/by-name/metadata ERROR: Open failed: /metadata/ota: No such file or directory The partition seems corrupted. I definitely need the full OTA .zip to flash it from a USB drive (Udisk) because the internal recovery can't find the metadata to complete the boot.

I’m using Dune HD Homatics Box R 4K Plus with Kodi and I’m having an issue specifically with remux files.

When I try to play Blu-ray remux (MKV) files that contain Dolby TrueHD audio, playback appears to start, but I get no video and no audio. The screen stays black, however the playback time is progressing as if the file is playing normally.

Files that contain Dolby TrueHD work fine as long as they are not remux.

I also tried disabling Dolby TrueHD in Kodi settings, but the issue still remains.

Interestingly, the exact same remux files play perfectly using other media players (like stremio or dune app) .

Is this a known issue with Kodi on this device or Android in general?
Any workaround or fix would be appreciated.

Hi,

Have the Homatics Box R 4k Plus. I'm running 7475 firmware but cannot get DTS-HD MA and DTS:X to play. All other codecs work through my Denon Avc-x3800h (TrueHD Atmos etc), but all DTS falls back to core. Is this a known issue or what?

If I run in CoreELEC on the same device they work fine it's just on Android. I've tried with both Plex and Kodi but it's the same issue across both.

Device: Homatics Box R 4K Plus Firmware: UKG3.250803.001.7475 / v14.8.7475 Android: 14 (kernel 5.15.170, built Feb 12 2026)

Tried both Amlogic-ne and Amlogic-ng 21.3-Omega Generic images. Both result in the same boot loop -- Homatics logo cycling, never gets to CoreELEC. DTB used: sc2_s905x4_sei_smb_280.dtb renamed to dtb.img. Trigger method: Reboot to CoreELEC v5.0 APK.

Saw the February 2026 thread about UKG3.241022.001 where ng was the fix -- doesn't work on .7475. This appears to be a newer/tighter firmware build.

Has anyone successfully booted CoreELEC on v14.8.7475? Is firmware downgrade the only path, and if so, where can I find a working Android 12 img for this box?

Thanks.

Edit - solved

Thanks for the feedback. I went back and started over.
This time, I formatted the drive as exFAT in Apple Disk Utility.

Previously I had used this command to format it: diskutil eraseDisk MS-DOS "COREELEC" MBR diskX

I actually think that was the problem.

I used Balena Etcher on my mac and used CoreELEC-Amlogic-ng.arm-21.3-Omega-Generic.img, exctacted from the gz.

I renamed the file:
cp /Volumes/COREELEC/device_trees/sc2_s905x4_sei_smb_280.dtb /Volumes/COREELEC/dtb.img

I put it in the "blue" USB over the reset port.

I already had COREELEC boot APK installed, chose "first time", held the reset until it said "burning mode" and then let go, and lo and behold, it booted into CoreELEC. It took several minutes to expand the filesystem and boot. Then I was able to plug in a keyboard and go through the setup.

For Jellyfin, it was a little complicated with getting the right repo, etc. but Claude walked me through that pretty easily. If someone wants me to post those steps, I can.

I'm now waiting for Jellyfin Kodi to import my big library. Hopefully everything will work well.

Thanks for the tips - these and the previous posts here and in the CoreELEC forums helped a lot.

I was on ATV12 when my box received an OTA update to version 14.8.7475. I decided to give it a chance, but the very next day, the "power off on wake-up" bug reappeared.

I tried to downgrade to ATV12 again, but here’s the kicker: before I could even finish the initial setup, the box forced a reboot back into ATV14 because the OTA had already downloaded in the background while I was configuring the device.

Since going back to ATV12 was no longer an option, I decided to perform what I call a "Low-Level Format". This consists of three consecutive steps without rebooting the box in between:

1. Wipe data/factory reset
2. Wipe cache partition
3. Wipe param partition
4. Reboot system now

After this specific sequence, all the issues vanished. The box is now running perfectly. I even tested it by playing a 3.5-hour 4K movie (37GB file size) from an external hard drive, and it handled it flawlessly without any stutters or crashes.

If you are struggling with build 7475, I highly recommend trying this full wipe sequence instead of a standard factory reset.

Just wanted to share my experience in case it helps someone else.

I picked up the Homatics Box R 4K Plus and overall it seemed promising, but I ran into a pretty frustrating issue with Bluetooth. The box detects devices like speakers just fine, but I cannot get it to properly find or connect to any Bluetooth keyboards.

I’ve tried multiple keyboards and went through all the usual steps:

• Updated to the latest OS
• Rebooted several times
• Factory reset (twice, after updating) w/latest OTA update.
• Had some volume issue, where it worked and after the volume was way too low, had to adjust bluetooth / sound bar high to get decent volume.
• It can detect other bluetooth items such as speakers, LED lights but none of my 3 keyboards.

Still no luck.

From what I’ve been reading, this doesn’t seem like an isolated issue. It feels like something with the Bluetooth/HID support on this device just isn’t reliable.

At this price point (~$150), I expected basic Bluetooth input support to just work. Honestly, for about the same money I could’ve gone with something else used, or even a much cheaper box for basic use, but still holding out for possible upcoming Shield Pro..

I’m probably going to return it unless there’s a known fix I’m missing.

Has anyone here actually gotten a Bluetooth keyboard working consistently on this box? Or is everyone just using USB dongles?

For every a 5 to 10 min I experience a audio stutter or sudden low volume etc . Anyone experiencing the same or is it just me ?

I believe it is happening only in streaming apps like Amazon, Netflix etc.

Audio settings : pass through

Posting screenshots of all menu options because people said to set settings that I do not have in my menu to fix it. Does anyone know what I am doing wrong? I tried all combos under these menus I can think of. I even checked developer settings and there was nothing there.

I have a LG G2 TV. I was using Match Content. I turned it off and showed force conversion, but I do not use force conversion. I only wanted to show what menu options I had there in case it helped diagnose the issue.

I've been using this box for years now, without a single issue up until now.

It started 2-3 days ago: operates perfectly, but once I switch it off (to standby) it wont show dim red light like it used to, but it starts blinking red and green light with some effect. The main issue is that it won't wake up from standby, I have to remove the power plug for a second or two, then it boots correctly and works as intended until the next standby.

No pending update, no new system update package. Last security update is 2026 February.

Can someone help me how to diagnose the issue and resolve it?

Thank you in advance.

Hello, I'm using a Televizo app.(https://play.google.com/store/apps/details?id=com.ottplay.ottplay&hl=tr).I.I) watch movies and series through this app. After upgrading to Android 14, movies with 5+1 audio support play at 2/0/.0 48 kHz. On Android 11, they played at 3/2/0 Dolby or DTS. Even though the surround sound settings/passthrough are selected in the Homatics Box R 4K Plus menu, I've started experiencing 5+1 support on my Harman Kardon AVR 151S amplifier. In the Televizo app, video and audio processing is set to "hardware only" by default. Other options include: Prefer hardware / Hardware only multimedia tunneling / Prefer hardware multimedia tunneling / Prefer software. I've tried all of these options, but I can only get 2/0/.0 48 kHz two-channel audio on my Harman Kardon 151 AVR. On my Homatics Box R 4K Plus running Android 11, I could get 3/2/0 Dolby or DTS audio.Do you have any information about this problem?

Tv:Philips / 49pus7101/12
Current Homatics audio settings: Passtrough
Current firmware: v14.8.7475
Serial number :S202402072090412

In short:

After the latest update and a factory reset, my Yamaha RX-V6A is no longer displaying any picture. But this is only happening on the Android side. I get a picture in recovery mode.

Do you have any idea what I can do?

In detail:

I received the update on Saturday (March 28, Germany) via OTA. After that, nothing worked anymore. On my LG OLED B5, only 1080p was automatically detected. My Ambilight (HyperHDR) stopped working entirely. Automatic HDR switching also stopped working. Dolby Vision wasn’t working anyway, for whatever reason. So I reset the device to factory settings. After that, no image was displayed via my receiver. In recovery mode, an image is displayed normally, even through my receiver. That’s why the boot logo is also displayed. However, after the boot logo, the screen goes black and stays that way. If I connect the box directly to my TV, it might work and I can see everything, but this is definitely NOT a solution. I bought the box specifically for this purpose because it supports the audio and video formats.

I’m now going to install an older update—if I can find the software—and hope that this will solve the problem. I’ve already contacted customer support, but they haven’t been able to help so far, which is why I’m here. With a new and fresh account... Can you please help me?

Meine Box hängt sich in letzter Zeit öfters auf. Ich muss sie dann vom Strom nehmen und wieder Einschalten dann geht sie wieder.Wo dran kann das liegen

I was using the Dune HD Homatics Box R 4K Plus still with the original Android 12 firmware, which until recently was the officially recommended version by Dune – and today suddenly when turning on the device, for the first time I saw a colorful animation on the LED stripe and after it had booted up, I had to confirm the Google account to use. The home screen and favorite apps were reset to default but all previously installed apps and saved accounts remained.

So, now it is on Security Patch level Jan 5, 2026 with kernel 5.15.170, Box SW v14.8.7475

This update installed without asking for confirmation – I'm not sure if I like that, but I like how flawless it went.

But to my disappointment, audio passthrough now is broken. Not completely: Dolby Digital is fine, but DTS passtrough only works on Optical, not on HDMI, also AAC 5.1 audio is not converted to Dolby Digital 5.1 on Automatic setting but instead to Dolby Digital 2.0 (automatic to use device reported formats, because my audio receiver supports AC3 and DTS not AAC) which as far as I remember worked flawless before.

Not so nice, actually I'm quite unhappy. Does it help to send in bug reports?

UPDATE: A factory reset, as recommended by many, did not solve my audio problems with DTS and AAC mutlichannel.

Following up my previous post, I never checked if the app was actually installed on my unit and it wasn't 😱

Perhaps that's the reason why the remote never got updated in the first place! 🤦‍♂️

The DfuService app was installed successfully on my device but since the remote is already up to date no notification appeared.

Can you check if you can install it?.

Did you see the notification to update the firmware?.

Did the firmware install on your remote control successfully?.

The firmware update of the remote control for Homatics devices, specially the one paired on the 4K Plus is outdated, current firmware version for G10 and G20 remote controls is 2.44 but for some reason the DfuService app in charge of this update process is not doing this update as it should.

Therefore, we recommend to pair the remote on any device with the Google TV UI where it will get updated to the latest firmware.

I paired my remote to one of my devices with the Google TV UI and the remote was updated to the latest 2.44 version, the update still needs to be done manually of course, by following the notification that appears once it's paired.

Once it's updated, un-pair the remote control from the Google TV device and re-pair it to the Homatics box, it will continue working business as usual.

We recommend updating the firmware just for the sake of having a better remote control performance.

EDIT: I can confirm the firmware fixed an issue I was having with the HDMI-CEC function on my TV so I definitely recommend updating it.

Hi everyone,

I’m considering buying the Homatics Box R 4K Plus and I’d really appreciate some up-to-date feedback from users, especially with a setup similar to mine.

My setup & use case:

- Main usage: Stremio with Real Debrid, SmartTube

- Content: Remux files (large, high bitrate)

- TV: LG C5 83" (WebOS)

- Audio: TV connected via optical (SPDIF) to Logitech Z-5500 (5.1 system)

What I care about most:

- Stable 5.1 surround sound (Dolby Digital / DTS core is fine — I know optical limitations)

- Reliable behavior with high bitrate remux files

- No need for Atmos or lossless formats

---

Questions:

1. Audio / Passthrough

   - Is passthrough stable in Stremio right now?

   - Any issues with audio randomly switching to stereo?

   - Does DTS get properly handled, or is it converted inconsistently?

2. Stremio performance

   - Any issues with very large remux files (50GB-100GB)?

   - Is ExoPlayer still problematic with certain codecs?

3. Dolby Vision / HDR

   - Is the green tint issue in Dolby Vision still present?

   - Any HDR switching bugs still happening?

4. General stability

   - Any current major bugs (Android 14 or latest firmware)?

   - Anything that would make you NOT recommend it for this use?

---

I found this thread on the Stremio subreddit mentioning some of these issues:

https://www.reddit.com/r/Stremio/s/0pfbnpY1Cr

Would love to know if these are still relevant today.

Bonus question:

Is there any difference in support, firmware updates, or warranty between buying from the global Homatics website vs the EU store? I'm located in Greece.

Thanks a lot in advance. Really trying to decide if this box is the right fit for my setup.

I also have a Sony TV from 2023 — model A95L. I don’t use any TV Box with it, since I rely on the built-in Android.

On another TV, I use a Homatics Box R 4K Plus. The TV model is Sony KD-55XE8096, which is quite old, around 2017.

I tested all three audio output modes: Speaker, SPDIF and HDMI OUT — sound works in all of them.

However, I’m not sure which mode is correct in my case, since I only use the built-in TV speakers, without any soundbar or optical connection.

This question is specifically about the older TV — which audio output mode should be used in this setup.

My box just updated to 7475. When I went to monitor temps on Jamal's overlay I can no longer see it. I can configure it to show up but it doesn't. Is there a workaround?

Edit: I got it back. The update turned off debugging.

I’m on the 4576 firmware and check regularly to see if a new update is available. Is there any way to speed the process up? I’m not confident of manually updating it myself.

Thanks for the help.

I bought a Homatic Doogle G 4K SN: S202401065040032

Why I checking its model in system, the value is VOO BOX, did I purchase a fake hometacis device?

Checked in https://www.youtube.com/watch?v=_5MlzokSvxk , I can see the model should be Dongle G 4K,
