    Well, I did it. No issues and now it's a lot faster to load the movie artwork when moving down the list fast. Thanks for your help guys. I really appreciate.

    Has anyone connected the Neo U1 to a 5GHz band Wifi AP,
    Under android my U1 would connect to my advertised 5GHz network ~860Mbit.

    I installed LibreELEC-S905.arm-8.2-8.1.3.img on a SDCard with gxbb_p200_2G_minix_neo_u1.dtb
    With this build connecting to WiFi only connects to my 2.4GHz AP.

    I have dried different channels in the 5GHz band and different SSID names but it just does not see the 5GHz networks.

    The regulatory domain gets set to CN not NZ.

    I cant find a way to force the regulatory domain to NZ, but that may not even be the issue.
    Has anyone got thier Neo U1 talking on a 5GHz band?

    Update: have now got it to see the 5GHz network but had to change to the lower channels.

    HI, I can't boot from Librelec 8.1.5-8.2, I tried with many micro sd card, or USB Stick, and no way I can boot, but if I create a 8.0.2 micro sd, it works I boot on Librelec. I am using a Minix U1, any idea ?

    Make sure you are using the correct device tree (.dtb) file for that version as they are different.

    Failing that, you would need to post this in the LibrElec forum here.

    I have tried this version Librelec 8.1.5-8.2, today and it works no problem i just downloaded the TAR file
    Put the file in the update folder and reboot your box instructions below

    Just today I loaded the latest LE 8.1.5-8.2 with the most recent device tree, on a Samsung Evo plus micro sd card. Initially the update got stuck on the Libreelec splash screen. I then copied the latest device tree to the card and the update then proceeded. Strange, as I had thought I had the latest device tree already copied to the sd card. In any case, all works OK, although I cannot see any noticeable difference to my previous LE 8.0.2e version. I have two cards, one with each version on it so I can alternate easily between the two LE versions to see any obvious differences if necessary.

    For me, it fixed the problem with the HDMI signal becoming lost and getting a black screen.

    Hello everyone, I,m not sure if this question has been asked but what are the pro's and cons of Libreelec 8.02 versus android Kodi 17.4? I am considering trying Libreelec. Now I know some people have video and audio playback issues with Kodi 17.4 but all my video files play smooth (x264, x265 HEVC 8-10 bit 4k SDR ) and all my audio formats(DTS, DTS-HDMA, DTS-X ,AC3, E-AC3, Dolby TrueHD, Dolby ATMOS, AAC and FLAC -transcoded as AC3) play with no issues on my Yamaha rx-v681 reciever. So to the people who use Libreelec, in my particular case would it be worth it to use Libreelec? Thanks for any feedback.

    It depends on what you are trying to accomplish. If the U1 is meeting your needs right now and not having issues with any of your playback, you might not stand to gain all that much, and you might prefer having access to the Android ecosystem with browsers and other apps.

    For me, I wanted a fast-booting solution that would dump me straight into Kodi. Didn't want to have to manually launch an app and keep up with Android security updates. So I just over-wrote the emmc with LibreElec. I don't use as many formats as you, but HEVC 10 bit and X264 are all playing great for me at 1080. I don't have any 4K displays or sources. I enjoyed having LibreElec on my box so much I bought another one for the bedroom and put LibreElec on it as well. So I'm certainly happy with LibreElec. The only challenge I have is needing to modify the audio offset once in a while. But passthrough audio works well for me on my main Receiver. In the bedroom it is just pushing audio through the TV speakers.

    If you set up LibreElec on an SD card or USB you can enjoy it without needing to wipe your Android install. I'd recommend that as a great way to test it out and play around with it.

    Good luck, and have fun!

    Thanks for your response, and I actually tried Libreelec 7 and there was no difference that I was able to notice. So I guess for now I will stick with Kodi 17.4 as I use multiple hard drives. Now quick question for you rabrol, Have you noticed any difference in sound quality between Libreelec and Android Kodi? As this would be a main factor for me using Libreelec.

    LibreELEC Kodi Krypton on AMLogic S9xx devices supports 5.1 / 7.1 HD Audio passthrough including Dolby Atmos and DTS:X

    You also get Multichannel PCM Audio output for Kodi FLAC Audio decoding.
    Something Android Kodi running on AMLogic Lollipop Firmware cannot do.

    The Android OS itself has PCM Audio output limitations vs what a Linux based OS like LibreELEC Kodi Krypton can do.

    LibreELEC Kodi Krypton as gives you proper high quality, reliable TvHeadend deinterlacing for TV viewing, which is busted in Android Kodi Krypton.

    The audio works great in LibreElec. As to the sound quality, you've reminded me there is something I need to look into. Perhaps one of my sample rates is wrong or something, but there is an only-just discernible resample-type of noise on higher frequencies that I am getting. I didn't have this in the past with LibreElec and my old Receiver, but after replacing my Receiver I and the kids notice it. The wife, and many other adults don't hear it. But like I said, I'm fairly sure that would be coming from my Pioneer Receiver as my old Sony didn't do that.

    I know from my experience with Libreelec and Android Kodi the audio quality was the same. As for audio output, like wrxtasy was saying is different( in android Kodi AAC, FLAC transcoded to AC3 on Minix U1 and Libreelec AAC, FLAC decoded to PCM). As far as the noise issue I haven't experienced that on either one.

    I was wondering do I have to hold the power button each time when booting into Libreelec? I noticed if I just had the usb drive in it will automatically go into Libreelec. Does anyone else's also boot without holding down the power button?

    Also, I was wondering has anyone used the ares wizard to configure Libreelec?

    You only need to hold the power button in the first time you install LibreElec onto sd card
    After this just switch on box as normal if sd card is inserted it will always boot to LibreElec if not it will boot to Android
    If you want to get to android after using LibreElec select reboot from internal in power menu
    It will then reboot into android without removing sd card
    Just to say I’ve been using LibreElec like this over a year never had a problem just make sure to use a decent sd card

    Hello, I just have a quick question for anyone using Libreelec. If I play a 4k HDR 10bit file on a 1080p tv (I'm aware the U1 doesn't have HDR capabilities ) will Libreelec play the file without washed out colors? UPDATE: Never mind I tried a file and the colors were washed out.

    I've been a long term lurker, and I've tried all versions of Kodi, xbmc for Minix, spmc, and of all, Kodi 17.5 generally works, though it crashes on occasion. But one major issue for me was playing VC-1 mkvs with the Minix. As I have alot of Bluray rips in the VC-1 format, I was seriously considering changing boxes, but then I came across this forum.

    Thanks to all for the help and tips. I am new to linux, so thought libreelec was beyond me, but I successfully installed it on USB and got it working off all 3 USB ports. I'm also going to try the Micro SD card to see if it runs faster, but so far, I am really impressed with libreelec. I had a few teething problems, but sorted them, and I can play all my VC-1 rips with no stuttering. I love how it boots straight to Kodi, and apart from the 1st scanning of artwork, Kodi runs so much faster. I absolutely love libreelec, but I am having a minor issue with audio passthrough. (I had the same issue with Android Kodi). I usually have to play, stop, restart several times to get audio. If this is the wrong forum for this post, my apologies, but if it isn't, any advice would be appreciated.
