Downgrade what? Stock ROM or CM?
If you have unlocked BL use my guide, it should work just fine.

The problem may be due to the fact that you have installed the ota without locking up your bootloader it happens if u want to upgrade what HTC releases officially u have to lock bootloader and then proceed as giiven.... But now I will suggest u to download the twrp recovery and recover it , until there will have been a stable mm ROM flash able zip available rooted for a5_dwg

Welcome to XDA!!
To install custom ROM, you will need to have a S-OFFed device to do so. S-OFFing need hardware tools, and it cost money. XTC2Clip and FireWater are the two known S-OFF tools that work on D820 for now.

But some in Mainland forums said i can update to 5.0.2 while S-on,they told me to relock the bootloader and flash the firmware(something like files for 5.0.2?) and i can flash a custom rom

If so, why dont you ask that guy from The Mainland forum, he should be the most well known of his own ROM.
Afaik, without S-OFF you can hardly do any modification to the system.

OTA (Over The Air) and flashing ROM are of totally two different thing, OTA came from HTC herself while ROM are created by people like us. So now which one is you proceed to do, OTA or flashing ROM?

Yes, you can search the web with your phone's CID and download the corresponding fw, after that rename the zip according to your phone MID, and place it onto your external SD Card, then boot into bootloader. The fw should be automatically flashed then.

Want to know if it is suitable or not? Use your CID to identify!
A TWRP backup can fix almost everything but not all.

I can probably see right now, you've done it wrong... Download stock rom from huawei.consumer... For some reason i thought it's gonna be android MM, but it was android N, so no problem here, just download stock rom and you will have newest android.
You probably downloader rom from xda, rom it's in .zip right? And you tried to flash it with TWRP?

Yesterday I had this issue, it's more easy than it seems. In Revolution Recovery for Nougat, flash the update.app ZIP with 6.0 , it will show you a lot of errors, but don't worry, it's ok. After this flash than DUALSIMOEM.zip and after that shutdown your phone and use the 3 buttons method to automatically ,,update" to B161.

That's because u don t have the bootloader unlocked Also, verify in Developer Options to have Enable OEM on, that's why you have an error in CMD

I will try your method but firsr I have a question: If i restart my phone I get a message on my screen that my phone is unlocked and can't be trusted. So that means my bootloader is already unlocked and I don't have to unlock it again? So I only have to flash revolution recovery and find the file in firnware finder?
Is there a instruction how to install revolution recovery and where to find the file...?

You can't install twrp with lock bootloader, you can't unlock den you can't , bad luck for you . If you want your phone to look good then try installing Xposed and mod it yourself
