I do want to try your remedy.
But downgrading is not possible with regular process.
And at present I don't want to use twrp, fastboot flash methods or so.
But believe me @Ashish that I'm dying to upgrade my asus to upgrade to latest official firmware.
--------------------------------------------------------------------------------------------------------------------------------
If I have to use twrp, or flashing I will rather like to install RR, AEX, LINEAGE, or my fav crDroid. )

You do not need to put twrp in your phone. Copy downgred file into your phone's internal storage, then restart your phone. And above the notification will come, then the oak will be downgred. After that, it will be done by putting your latest firmware

I did as you advised
1. Clicked link and dwnld the file through mobile
2. Moved file from downloads to topmost in internal storage
-- system did not detected dwnloaded file at all
3. Restarted phone
-- system did not detected dwnloaded file at all
4. Powered off phone and charged up to 100%, then powered on
-- system did not detected dwnloaded file at all

Please see if i made any mistake!!! and advice how to proceed.
Thank you
