Can't flash custom rom

[Dennis ingate]

Hi, I'm new here so bear with me.
I have a Samsung galaxy note pro 12.2 lte and I'm trying to flash a custom rom (lineage os android 11) to it. I have installed twrp for the device and downloaded the rom. The problem I have is that when I try to flash the rom using twrp it fails on error 255. It gets to the point where it doesn't seem to recognise the device. It's says the software is for a note pro 12.2 sm-905 viennalte but the device shows as a full stop.what is a "viennalte" as opposed to just an lte?
Any ideas please

Are you sure thee right lineage os? Where did you get it? Do you have a link?

It needs to be exactly for your device. Flashing a rom not made for you device could mess the phone up.

That's what I'm trying to ascertain. It says that the rom is for this device "galaxy note pro 12.2 sm-905 viennaltexx with qualcomm processor" but I can't see the word "vienna" anywhere on my device so am unsure if it is the correct one.

where did you get this rom? do you have a link? on lineageos site, your device is not listed. is this an un-official custom rom?

I think it must be unofficial because the lineageos site shows this device as discontinued. So with that in mind I'll abandon this.
