Use the rollback zip not any random zip.
What is you file extention end.....it should end with .zip
When u download the rom check its extension.jar or .zip
If its .jar rename to .zip
Download according to your region.
This has nothing to do with the file name, he hasn't used the correct roll back firmware.

Make sure you follow the instructions in the first post of the Open Beta 1 thread (included below) and download the correct version for your device/region. Also, as stated in the instructions, roll back will wipe your device, so back everything up first.
Note: OBT is open beta, MP is Android 10
OBT to MP rollback guide—via Local OTA update
Note: This upgrade method will erase all the contents of the phone, please be sure to backup first
1. Download the latest ROM upgrade zip package from the specified server
2. Copy the Rollback package to the phone's internal storage, and remove the '.jar' file name extension if present so that the file ends in '.zip'
3. Go to Settings -> System -> System Updates -> Click top right icon -> Local upgrade -> Click on the corresponding installation package -> upgrade -> System upgrade completed to 100%
4. After the upgrade is complete, click Restart
5. Update successful

So what i do...
I want to change, hydrogen os 11 to oxygen os 10 , so what can do...
Any other method...
Try this, it should be a roll back package for Hydrogen OS to A10:
The following are the downgrade packages available for downgrading to the stable version of Hydrogen OS 10 (Android 10):
OnePlus 8 Pro
They are from here:
I think you should then be able to download and install the latest 8 Pro software from your region's OnePlus support page > Software Upgrade.
Sir i want to change HYDROGEN OS 11 in to OXYGEN OS 10
hydrogen to oxygen.....
Not hydrogen os to hydrogen os
So give any method....
Download the file, move it in the root directory, so not in a folder
Install it in recovery mode.
that’s what I would try. Don’t know if this would work with hydrogen but I’d guess this would work
al at your own risk
I saw you want to go back from Hydrogen 11 to Oxygen 10 so this probably won’t work either. You’ll have to use TWRP I guess
