FWIW: I've been simply using zcat for years without any issues:
Codezcat LibreELEC-RPi4.aarch64-12.0.1.img.gz > /dev/sdXIf you are using Linux, Windows or MacOS you can also simply use the Raspberry Pi Imager - LibreELEC is available in the Mediacenter section.

so long,
Hias
pi imager is a phantastic recommendation! I just installed it and it looks really nice. I'll definitely use this in the future 
With dd did you unzip the image?
Codegzip -dc LibreELEC-RPi4.aarch64-12.0.1.img.gz|dd of=/dev/xxx bs=64k
oh my god, i'm the biggest clown alive... I forgot to unzip it. I really need a break from computers now. glad that holidays are around the corner.
Thank you so much mglae 🙏🙏🙏🙏 its working now
Thanks everyone else!
I'll now go ahead and prepare this pi and make it a gift for my xmas parents. Got a case and a remote for it too.
using this: Raspberry Pi 4 Model B, USB-C, 5.1V, 3A
(it says that it is supposed to be the official PSU, has the logo on it)
Hi everyone, this is the error that I see when plugging the pi to the TV:
Unable to read partition as FAT``I know that this is a very generic error and I've seen tons of threads about this. Most folks say that the micro sd card is broken and people should get a new one. I tried a 32GB micro SD card that I had used for a different pi project in the past and got this error. Then I just now bought an 8GB micro sd card. I unpacked it and the very first thing that was ever done with this brand new SD card was format it with libre elec. And again I get this error... How can this be with a brand new card? I'm starting to think that the micro SD card is not the issue here...

Any recommendations what I could try next?
