I believe that’s how it works, but I could be wrong. Let us know how it goes.
When is 2.17 going to work on the RPi 3 B+
To answer your question, it will happen at the exact moment of the smallest measurable unit of time after your death BUT … will still occur at the last absolute measurable moment of time just before you pass into, which after life you believe in before you lose conscious awareness, but yet still some how manage to be long enough in THAT in between moment for you to realize "Damn, that’s so beautiful, some how that Plex got it working in the moment of my death. Too bad I waited this long. …

While this build works it is buggy as mentioned.
I recommend watching this thread for a new build that works on the 3B+
I have reactivated my old 2B for now, it runs the nightlies well.
Please ping me if you happen to create a workign build. Would love to use the power of the 3B+ for plex. (in a way I purchased it for this)
take care
Andreas
Just to finsish my endless search - there is at the moment no runable Plex Client for Raspberry 3b+, right?
I can view movies with raspbian desktop on the browser, but I didn’t get working neither RaspPlex nor PMP running on my raspi 3b+. The latest nightly build from this site didn’t work as well.
I need a client which is controllable via openHAB.
Quite anoying, that plex seems not to work on this issue 
plex + kodi // plus plex for kodi plugin seems to be a nice way to make the 3B+ sing
see here: PlexKodiConnect: Kodi Plex Integration Done Right
and on the main page: https://www.plex.tv/apps-devices/#modal-devices-kodi
The Kodi + Plex plugin works ok for me as a player target on the 3B+ as a fling/cast target from my Android phone. I write “player target” instead of “works well” as a few glitches remain. This includes tracks playing twice and info on currently playing track being incorrect.
I have also been hacking on getting the Alexa interface to Kodi/Plex-Plugin working and this may have led to the symptoms above. Currently the Alexa interface is hit-and-miss. It always plays the correct media (if it is identified correctly verbally) but with respect to the sound successfully exiting the Pi node vs my Echo Dot itself…well sometimes it works and sometimes it doesn’t.
So to recap, the 3B+ with Kodi / Plex Plug-in plays lovely Plex music out my HiFiBerry Amp2 HAT but cosmetically its rough which may or may not be due to my Alexa hacking frustrations.
Hope that helps!
I have rapsberry pi 3b+ working, the link in the first post is the version I’m running but it’s offline since some time. If you want I could try to find the image on my PC.
@kapiszon53: A working version would be wonderful. Were you able to find the image on your PC?
I have found this file but there is a new version available which is working much better:
We’ve posted a new test build of the embedded PMP at the usual location: https://nightlies.plex.tv/public-test/plexmediaplayer/embedded-testing/ Specifically, https://nightlies.plex.tv/public-test/plexmediaplayer/embedded-testing/2.25.0.948-77f379e1/ This build bumps the LibreELEC version from 8.2.2 to 8.2.5. The most notable difference is that 8.2.5 supports the Raspberry Pi 3B+.
In the next few days, we are going to bump the version of libcec in the LibreELEC build to a version beyond what’s in 8.2.5. In our internal testing, this appears to stop automatic tuning to the PMP device after the TV is turned on for those with LG TVs.
Hi gbooker, which one of the 4 files in that directory would be the correct one to flash onto a 3B+?
2 of the files are x86_64 and 2 are arm. The raspberry pi is not using an x86_64 processor so you wouldn’t want either of those. The .tar files are useful for updating from an existing version to a new one (throw it in the Update share if you have enable SMB on the device). Updates can also take the .img.gz file but the update process a bit slower than the .tar. The .img.gz files have a compress bootable image so you’d want that. Decompress it to the .img and flash that on your SD card.
So, you want the RPi2-arm.img.gz to put on the SD card for a 3B+.
Working well so far after a short evening of watching TV. Thanks
Only thing i cant see in the menu anywhere is a network report of some sort, so i can get the IP of the unit, so not sure how i could get that.
I am using this latest build on a Rasp Pi 3 B+. Works perfect straight out of the box. Thanks a million!!!
Hey guys. I’m waiting for my Raspberry Pi 3 b+ to arrive. I was wondering if HDMI-CEC is working with PMP and Raspberry Pi 3 b+ so I can use my TV remote for controlling the player?
I was testing mine yesterday with a Samsung TV and this was working perfectly. I was able to do all navigation and basic media controls using the TV remote.
PMP works pretty well overall on the Pi 3b+ except for page refreshes when you change between Home>Movies>Shows sections which is really slow when compared to my Roku 3.
Thanks a lot for the confirmation. Will test mine in a week or so. Hope it’s better than PS4 which is buffering content for some unknown reason.
I am running 2.28.0.960-72d2c6aa on my RPi 3 B+ without any problems. Only the UI is a bit laggy though.
When can we expect a stable version? Would be nice if Plex gave the embedded version some more priority.
Thank you 
Is there any reason this shouldn’t work on the A+? I can boot it with a known working Raspbian SD card, but when trying 2.25.0.948 or 2.28.0.960 I get nothing on the pi at boot, just the rainbow screen (activity light stays off.) I’m on linux and downloading the arm.img.gz, using gunzip to get the img, and flashing with dd.
