    I tried to search for help on xda but no luck,and i.m reading everywhere that this can be done easly flash ATT firmware to US unlocked note 9,i flashed before few phones and this is the first time i'm having this issue

    it is weird you say that, bcuz, when i were to add "the 4 files" in odin (i flashed several times now), i left the 4th file out (CSC file), 2 flashes back (still trying to get rid of partitions, still failing at it, everything on youtube is in indian), and my phone went from unlocked to a sprint phone,

    OT, don't mean to Hyjack, but may teach you something as well
    I NEED TO GET RID OF THIS :banghead:
    My OCD is driving me nuts, will not use the phone until I know I have wiped it clean, w/o going to the local samsung shop.
    My phone never ever had the partions, just the missing att bs from factory.
    But, after it was obviously rooted when hacked, that occured, since I never modded the phone.

    2nd file may be the key (open files inside of it, and put in the changed ext IMG file and just install it via AP sole flash), so I think I know how to cure, but afraid.
