cmdline.txt is on the same /flash partition which is mounted read-only by default.

It appears to work when I plug it in directly to the TV, but I've edited that file, added the line, verified that it's there, and it still does not show the LE menu. All I see on my screen is No Signal on Hometheater HDMI 2.

Connect the RPi4 directly to the TV.
If this doesn't help add "video=HDMI-A-1:1920@1080" to the end of /flash/cmdline.txt (everything has to be on a single line!) to force HD mode and disable any 4k modes your TV/AVR may advertise.

I will try that and see if it works. If that doesn't then I am not sure how to add the line to cmdline.txt, or how to even gain access to that file. I also don;t have any 4K devices, if that helps.
Thanks,

@HiassofT - I am trying to write to that file using WinSCP but it won't let me do so. The RPi4 does indeed work directly plugged in to the Samsung TV HDMI 1 port, but as I stated, I am not sure how to write to that file. I am assuming it's a permissions issue?
Thanks again,

That doesn't really seem to be helpful to me. I could be wrong though. The thing is this. My TV and Amplifier are newer than my PlayStation monitor, so why would the cable be an issue on the newer, but not the older. I am more than willing to buy the HDMI 2.0 or 2.1 cable, but I can't even seem to find one at Best Buy Canada, or Canada Computers. I unfortunately don't sue Amazon. This is just so confusing to me. I really didn't think the RPi would give me such headaches.

So here's the situation I'm experiencing. The RPi4 does indeed boot-up, and LE is working, but this is only on my PlayStation HDMI monitor. If I connect the RPi4 where my existing ZBOX is, it just displays an HDMI 2 screen that says "NO SOURCE". I don't know why it won't display the LE interface. When I can take any one of my LE setups on other ZBOX's, plug them in, they work. My Denon amp is set to HDMI 2, the TV is also setup to HDMI 2, but I cannot for the life of me figure out why it won't see the RPi4. Any ideas would be greatly appreciated.
Thanks,

Probably dead microSD - check your LED flash codes as described here.
I just got it with my order. It is brand new, plus I have another 128GB (brand new) and that also doesn't work. 
Hi All,
I am not sure what I am doing wrong, but I put my RPi4 together with the Flirc Kodi case, board etc and plugged everything in but nothing happens. I installed LibreELEC-RPi4.arm-11.0.3.img.gz using the LE installer on my MicroSD 128GB but my system is just telling me there is "No Signal on my HDMI 2 port". If I pull the MicroSD card out, I then see the following. I am completely lost, and would appreciate any assistance.

Oh man,
I just received my RPI4 on Friday, to find out that there's now an RPi5 on the way. 
Hi chewitt,
Does this mean that I can use a Sandisk 256GB MicroSD card instead of using an external SSD card?
Regards,
Shedrock
I'm an advocate for media content in a NAS device (Synology etc.) instead of connecting USB drives to boards, but 69GB isn't so much. If you can splurge on an SSD it will be lighter/cooler/faster/less-power than a mechanical drive.
Thank you.
I am about to purchase my PI4 this week, but I just have one more question (I think). If my LibreELEC backup size is 69GB's, wouldn't that mean that I should be using an external SSD drive, for example: a Samsung 870 EVO 250GB?
Thank you in advance,
Shedrock
It’s absolute overkill for LE. Why not choose the RPI4 2gb model. Great back up community behind it too and a fraction of the price.
So this is all I would need, and maybe a 32gb Micro SD card? I also plan on getting the Kodi case if I did go with a RPI4. I just don't know what else I would need.
One of my concerns is that I have a very large library (5000+ Movies and 20,000+ Episodes) and I am using a 250GB SSD drive, and it has used 178 GB so far. I am not sure if I would have to use an external SSD drive on the RPI4, and in doing so, would that not be a slower option to run LE, as oppose to the Micro SD drive, which appears to be insufficient in regards to capacity?
Thank for all your advice,
Shedrock
Sorry to be a pain guys. I am still shopping around and trying to research the best mini PC to run LibreELEC Nexus on. Can someone please tell me if this will do the job?
Regards,
Shedrock
Would this PC be sufficient to run LibreELEC Nexus?
ASUS PN50 Mini PC (AMD Ryzen 4000/256GB SSD/8GB RAM) - En - Only at Best Buy | Best Buy Canada

Thanks, does all NUC have built in IR Receivers?
I've actually been trying to find that out myself, but no luck so far.
I bought the FLIRC case just to support Kodi once more.
I will also do that. Thanks for the info.

Just curious, why do you think you need an actual PC?
Most people seem to use Raspberry Pi 4, and they are starting to be available again for reasonable prices. No IR built in though. A OrangePi 3LTS is even cheaper, and does have IR built in, and can do 4k. No wifi support though.
So if I were to purchase a kit like the following, would it do all that I need to run LibreELEC? And would I still need an IR adapter of some sort to work with my Harmony Remote?

Just curious, why do you think you need an actual PC?
I guess I am just old school. I really just want a system similar to my Z-Box where everything is there and all I have to do is install LibreELEC, configure and go. I do have plans to purchase a RPi 4 just to play around with, but that will be later on this year if they are available.

Hi all,
I am finally going to be purchasing a new system because the one I am currently using for the last 10 years is outdated to say the least. 
My current system is ZBOX-ID88 with 4GB of memory. I am still on Leia (18.9) and I would like to use the current versions of LE.
Truth be told, I know nothing about hardware and what I need to purchase. I don't use 4K, but it's not off the table. I would like to get a system that would be able to handle everything current, or at least be good for a few years, and it must use IR, as my Harmony One is IR. My budget is $1,200.00 CDN. I would really appreciate it if someone can lead me in the right direction as to what fully loaded PC to purchase.
Regards,
Shedrock
