Yes I did replace the dbt.img, it is the same as I placed with Kszaq's 8.2 build, am I right?
Yes, I use gxm_q200_3g.dtb and a customized remote.conf
Did some test using some 4k video files
10bit - OK
HDR - OK
jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv - OK
DTS passthrough - OK
external Subtitle - OK
Netflix & Amazon not tested
What did I do wrong?
You have to know what You are doing 
Did You replace the dbt.img ?
Regional settings set to english after fresh install, You can change language after a reboot.
I can confirm working LibreELEC-S912.arm-8.90.1-K on my S912 - but I had to replace dbt.img
In addition to my Tanix TX5 Pro post with dedicated codec.info button made for LE7 (based on Jarvis)
Here's some more improvments to this tiny-handy remote to meet LE 8-9 (Krypton) demands
Basic layout stays the same, but some buttons have several functions now via keyboard.xml:
.
.
This remote works with S912 Box Vorke z6 - maybe vorke is a clone from Tanix
I begin to think that you can't simply install Jarvis on LibreElec 8.2 , am I right?
.
.
It´s time to read in this and other forum(s)
You will find much information, for example about the issue external srt subtitles and framedrops and much more
Is there a tutorial to do this.
Need Putty for up/downgrade Kodi or can you make it right from LibreElec?
Ye need to read the FAQ [HOWTO + FAQ] Install community builds on S905/S905X/S912 device
Updating
Update process looks the same for SD, USB drive and internal memory installs:
or
Downgrade You can use the same way or do a fresh install
Do I miss anything or this should work !?!?!?!?!
Try it - this should work - but I don´t know it because I don´t know You skin.
In worst case the skin use an own favorites.xml
I´ve the same problem ( no reboot form internal ) in my S905x with the skin "Skin MOD - MOD AEON MQ7 KRYPTON", do you think this procedure will work for me ?!?!?!
To add the menu entry "Reboot from Internal" by editing a .xml file depends on the used skin.
Most important entry -> <onclick>System.ExecWait("/usr/sbin/rebootfromnand")</onclick>
I don´t know the skin "MOD AEON MQ7 KRYPTON"
A manual to edit custom entrys -> How to add a custom script shortcut in KODI | Multi Boot Pi
One way will work in every skin.
Edit the file favourites.xml -> Favourites.xml - Official Kodi Wiki
<favourites>
<favourite name="Reboot from Internal">System.ExecWait("/usr/sbin/rebootfromnand")</favourite>
</favourites>
Good luck and don´t forget - LE is a DIY system
You have to replace nr. 1. <control type="button">
1. should be <control type="button" id="15">
Summary(my way):
#ssh to the box
ssh root@<ip-address>
vi /storage/.kodi/addons/skin.confluence/720p/DialogButtonMenu.xml
# use cursor down key to go to an entry like <control type="button" id="nn">
# entry ends with </control>
# use cursor down to go one position under </control>
press i key
copy/paste
<control type="button" id="15">
<description>Reboot to Internal</description>
<width>340</width>
<height>40</height>
<textcolor>grey2</textcolor>
<focusedcolor>white</focusedcolor>
<align>center</align>
<textwidth>290</textwidth>
<texturefocus border="25,5,25,5">ShutdownButtonFocus.png</texturefocus>
<texturenofocus border="25,5,25,5">ShutdownButtonNoFocus.png</texturenofocus>
<onclick>System.ExecWait("/usr/sbin/rebootfromnand")</onclick>
<pulseonselect>no</pulseonselect>
<font>font13</font>
<label>Reboot to Internal</label>
</control>press esc key then :wq (save and exit)
Change skin described by the_bo in 6.
6. Switch to a different skin and switch back to confluence to refresh skin (or you can reboot box). Press letter s on your keyboard to bring up the power menu.
You can select "Reboot to Internal" in shutdown menue using confluence skin
Hi Tim,
Can you give me a clear work around to edit the .xml file.
Which tool do I have to use: WinSCP or Putty??
I am not a linux expert so please use donkey language.
I am using the confluance skin now (just like this) and would be very happy if I could add a button to boot back to Android in the power menu.
I have to look ... don´t remember in my mind.
The tool I used is the vi editor - connected via ssh from Linux shell(I don´t use windows tool to configure LE)
I think, that is only for the default skin, Estuary. (I might be wrong)
You can modify every skin - my way was editing .xml file in skin folder
Display MoreThis is a nice app in Android, but if you are in LibreElec the only way to come back in Android again is:
-Shutdown LibreElec
-Mainpower off
-SD card eject half out
-Mainpower on again
-Then it boots to Android again
If you want to use that nice app in Android again you need to insert the SD card first again.
...
That´s wrong.
Power menue in LE allows to boot android
Is there a way to fix this, I use Tvheadend all time,
But, my question was different - anything better to recommend than odroid-c2?
It depends
S905x Boxes are cheap and need a little DIY
What do You want to do ?
Playing 1080p video from HDD, USB or NAS ?
Want to watch live tv or stream(netflix, amazon) ?
I´m only playing music(mp3, flac, dsd) and videos(720p, 1080p and UHD) from NAS using s905x box
Also own raspberry pi3 - not longer using the PI for watching video because I converted all my videos to HEVC(h.265)
raspberry PI -> x.265 software decoder 
s905x box -> x.265 hardware decoder
I usually have problems with playback of buffering 1080p videos with some Kodi plugins. Googled a bit and everyone say same thing - RasPi3 is not a perfect device for media center
rapberry is a perfect media center device - 1080p videos are playing well
Buffering issues -> check network etc.
Can anyone guide me in the right way pls ?
Ask the author of youtube addon
I see. Is it working fine otherwise or have you observed any deficiency in CEC operation on your box?
CEC is working for me - play/stop/pause etc.
Don´t need much special key like others
