This is why recoveries are specific to each device, no idea why you flashed a G2 recovery on your G3..

Or try LGUP.

I had exactly the same problem and didn't find a solution.
BUT maybe you can send your G4 to LG and they repair it for you (because of the bootloop issue).

Please suggest how to make it work or where could i get official Optus firmware H815T10H.
Thanks in advance.

Are you sure you have a H815?? There shouldn't for any antirollback for the H815T

well... another case to the list.
You must open your G4 and see in the motherboard what model it is. Probably you have a refurbish G4 (maybe LS991 model).

Sorry I can't help with that. That's not simple if it's possible especially if your getting antirollback problems.
I'd suggest returning the phone since it's been tampered with

You could try a factory restore if you haven't already. Also, the LG Bridge app for your pc (download from LG site), may provide an update or an option to reinstall your firmware.
The alternative is to check (private message) with other H810 XDA owners in relevant threads to see if someone has a copy of a suitable stock firmware.
Note: If you want to install a custom rom to update to the latest security patches, etc., , you can unlock your bootloader unofficially with steadfasterX's brilliant work (many H810 users have gone this route now) - check it out here: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU. Read the OP thoroughly and make sure you understand it fully. You will have to have an ARB version of two or less in order to go this route, so before upgrading to any other H810 firmware, check your ARB version with SALT.

thanks for reply.
I already tried the factory reset, but no lights on.
Tha LG Bridge won't work as i know cuz i don't have active AT&T Sim card and i don't live in tha usa.
Asking other H810 XDA Owners for a suitable stock firmware, i really didn't think about it so i will give it a try.
My H810 already have H81021y software which has ARB 3. so no root for me, i guess :crying:

Yes, no root, no bootloader unlock for you, unfortunately.
However, ALL MAY NOT BE LOST ... check out this thread that I found: link... to Android 6.0 MM h81021y archive tot
There are a couple of links to the firmware you seem to be looking for. It is a TOT file but you should be able to flash it following the TOT method as outlined in this thread: [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method - scroll down to the TOT method.
Good luck.

Could also be the ilapo if a factory reset does not solve it.

uhm what about using the search box ???
Also find the bootloop fix list in my signature .
Still its just a guess . Check the first 3 digits of your serial (sticker behind the battery). If it starts with 603 or lower you board will be sooner or later affected by the ilapo .
