Compile a ROM

never ventured this far so I flashed the V60 ROMS since you can flash any model but didn't know since it doesn't match the build # data will never work volte I'd like to try my hand at it. I'd like to know will data never work on AOSP ROMS? Can I take an existing ROM change the model # & inject the correct data settings so it can be a daily drive? or is the LG V60 just a pretty ROM paper weight....
