Download the firmware from here

Note 1: If you get "Waiting for device", install drivers properly.
Note 2:The zip will not extract, you have to use it directly without extracting. So don't bother trying to extract the zip, it will always give you error.
Note 3: If using windows 8/8.1/10, make sure to disable driver signature check before installing drivers.

Install fastboot drivers from below if not installed previously..

FastbootDrivers1 or FastbootDrivers2

Download fastboot tools from the attachement, extract it somewhere..
Method 1: pushing the RUU through PC

Now place the above downloaded zip inside the same folder having "fastboot.exe" and rename it to "firmware.zip"
Open command prompt onto the current folder (Shift+Right Click on the folder then select "Open Command Window here")
Boot into fastboot mode (Vol down+ Power then select fastboot)

Now type the commands as given below..

1. fastboot reboot-bootloader
2. fastboot oem lock (If Bootloader is Unlocked previously otherwise skip)
3. fastboot oem rebootRUU

wait for silver htc logo

3. fastboot flash zip firmware.zip

Now some progress bar should appear onto you phone. Wait for it to finish, after that

4. fastboot reboot

Method 2: from the phone itself thanks to @Kellwa
1- Lock the bootloader using fastboot oem lock command
2- Rename the downloaded zip to 0PFJIMG.zip
3- Put the file on sd card and insert it into mobile
4- Reboot into bootloader and it will ask you if you want to update
5- Press VOL UP to say yes

I am downloading OTA since past 6 hours, every time it gets corrupted and starts from 0, I am fed up. I want to update right now and I found this thread, so this is the official HTC Stock 5.0 ROM for HTC Desire 820 Dual SIM ? Has anyone tried flashing it "SUCCESSFULLY" via fastboot?

No, that is RUU for kitkat 4.4.

To update to lollipop, either download it in phone or wait for anyone to upload it then download it on PC and then flash it.
And your download gets corrupted, better watch your Internet connection. Get a stable connection (WiFi preferred) then download the update

I have tried to download it three times from different machines. Successful downloaded every time. However, the downloaded zip file seems to be corrupted (cannot open by any of the zip viewers). I think the original file is corrupted. Correct me if I am wrong.

I have successfully upgraded in one attempt. But lost my boot.img.. We need help of some person who can upload the complete ZIP. This will help me and all those who are receiving corrupted update file.

From stating machine, if you mean PC. I would like to know how are you downloading ota on PC.AFAIK, OTAs are downloaded on phone itself only

The Zip you downloaded is not supposed to be opened, it has to be used directly. Its normal that the zip won't extract. It does not mean at all that your download is corrupt
