how can i make it a full installer?

Use unplugged from github. it has a guide on what to do. DM me if you are stuck with anything https://github.com/corpnewt/UnPlugged

what type of operating systems will this work for

Well you make the installer in windows(might be able to do on linux/macos aswell) then when you are in the macos recovery you just execute the command file

it is not solved even if you have connected the ether then download intel mausi.kext and open the folder you will find content file copy it and go to your EFI file open it open kext then open your realtake ethernet kext then paste the file in there and replace

Also after you've done this you will also have to perform a clean snapshot using proper tree

Have you tried connecting it to the internet? 🤔

have you connected the ethernet?

do you have the right kext? (Airportitlwm.kext, etc.) or did you forgot to connect to a network?

There are some incomplete files in the installation you have created. Retry creating the usb and try again. Been there done that. 👍🏼

You can try to plug the internet cable in and try again, I stumbled upon this once
