Samsung A03s

I have been having trouble flashing my Samsung with Odin .I am needing to download unlocked firmware. I am trying to change the CSC and I thought that I had it once, but when I went and looked in the "about phone" section, it was still the same. Then when I try and use a different firmware, Odin will stop on setup connection. will someone please help me.

Welcome to AC!
These are US version?
Unlock firmware you will Odin 3.14 patch b (prince comsey)

You'll also need Frija firmware tool for latest software to download and both Odin and Frija can be downloaded off XDA website

Use all 4 slots in Odin once you extract the firmware zip and put them in their corresponding slots except CSC use Home CSC firmware in Odin CSC slot so you don't factor reset

Make sure to use A037UI in Frija with CSC code XAA or TMB
