Partition layout has been changed in Lollipop and you can't simply go back to KK.
Rooting L is not an issue, just wait for a working recovery.

1. Install or make sure you have installed proper adb and fastboot drivers on your computer
2. In bootloader, goto FASTBOOT
3. Connect your phone to your pc via usb cable
4. Now run HTC_A51_TWRP_Recovery_3.0.2-0_htcui.com.exe from this thread.
5. Done

The string after "OS-" become blanked ?
If your answer is yes, do feel free to find any MM RUU on this forum to flash on your device as from your bootloader info. your device seems to be S-OFFed. Which means any Desire 820 RUU SHOULD work on your device. But remember that you should choose the RUU that have the same number of sim slots for you.
P's1: I wont take any responsibility if you bricked your phone.
P's2: You may refer to this thread for more information.

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.

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.

Going back to stock ROM after installing a custom one

Just do a clean install (wipe internal memory also) and install the ruu
Also you can find multiple ruu files from the link thread below

So your phone have 8.0 firmware. If you want stock 8.0, just enter my post from link below and download stock zip flash by TWRP. If you want stock RUU, you need follow DOWNGRADE to Nougat post.

Your CID is rare for single sim variant
First you need a Ruu for ur specific CID
then the rest of the steps are pretty much the same.
