I Want to Learn How to Change Team Logos As Well As Loading Screens

Hello everyone. I am new to modding and was wondering if there is any info on how to change team logos, loading screens, and other graphics like the ones that show up in the background while picking teams in Play Now. Links to any other forums or videos would be greatly appreciated!

I am planning on recreating the CBA in 2k20 taking inspiration from https://bbs.eyeuc.com/t/79695 's mod that I unfortunately couldn't figure out how to get.

I doubt it if you even don't know how to change logos.
Btw this CBA mod is not free? How to get it?

I mean all I have to do is learn how to do it correctly!

Yeah... I can't get a WeChat pay without help from someone who already has it and the guy "qq" is apparently not well and can't take payments. Plus, I'd rather just learn how to do it myself for future reference when I want to do other projects.

Look at downloads that have already modded these files. Use these as a guide as to what file textures that are needed to have replaced. Shuajota and 2kspecialist may have some files.

I will do that! Thank you so much for your help!
