RPi4 and RPi5 are using 64 bit LibreELEC with 64 bit Widevine now (LE12+). That's a future-proved setup.
I was wondering, if this means, on the long run, when Google will not release a 64Bit arm widewine...
I'm still worried if Google stops releasing 32Bit widewine for arm...
No signs that this happens.
If you still need help, translate your initial post into English.
Will RPi3 and RPi5 and Kodi on Windows be supported?
What's the relation to LibreELEC?
So the HDMI-A-1 is the HDMI0 port on board ?
Yes.
Thank you for your answer chewitt, yes, I tried 2 different HDMI cables.
Which HDMI standard? They should be HDMI 2.0 or 2.1.
2025-06-12 19:38:12.771 T:1000 info <general>: Disabled debug logging due to GUI setting. Level 0.We need log level 1.
You can activate it by creating an advancedsettings.xml file.
You didn't read the forum rules. Remove all banned add-ons and repos. Post another log, if the issue remains afterwards.
What do i have to do to make it install le on the other, new 512 gb datatraveller?
If you don't see the preferred target device, install wherever possible, copy the two resulting partitions to target, and change ID's:
However these will need to be changed, grub2win allows you to get the partition table including BLKID and you can use that to replace the ID's above as needed.
No guarantee that it works, I don't use Windows anymore.
It's not installed correctly. Do it again, but use Grub2Win:
Try the Audio Profiles add-on. Not sure if it works with the internal analogue audio, but it should work with USB audio.
You can see hidden files and folders by ls -a command.
Are there remote controls such as tvbox to connect to the Raspberry?
You can use the TV remote control for the RPi. The technology is called CEC, and uses HDMI to send remote calls to RPi.
I can do putty. Is there a text editor built into LE.?
Yes, nano.
I can't actually get into the installed version to turn logging on. When I SSH into it the /logfiles directory is empty.
Nobody was talking about that folder before. 
Activate log level 1 at advancedsettings.xml, and reboot. Then run pastekodi from SSH, and post the resulting URL.
If you don't get any log files, then we already found the cause of the issue. Kodi has no write access on your SATA drive.
Use LE 13 Generic Legacy Nightly for NVidia GPU. Upgrade your current installation on SSH:
Code
cd /storage/.update
wget https://test.libreelec.tv/13.0/Generic/Generic-legacy/LibreELEC-Generic-legacy.x86_64-13.0-nightly-20250529-8c39f0c.img.gz
reboot
