I haven't downloaded any firmware yet. I have been to the link you sent before but for some reason it doesn't work for me.. I can enter my info but the button never becomes active to actually search.
What I meant by changing is I assume for different android versions. I have read so much that I am now confused. Do I use the latest odin. the modded odin, the patched odin.. Then I read one place that uses adb tools and another site mentions a different tool that I cant recall now. I found one tutorial on xda website but it is from 2018 so I am thinking it maybe different now?
