    Id like to stay on carrier firmware at this time i think. I just want to have the latest updates possible.
    This is the steps :

    Windows computer needed

    Latest Odin can Google it from XDA Forums and download the latest should be Odin 3.14.1 / and Frija tool or samfirm (i usually download both)

    Download samfirm v0.4.1 tool and frija, extract it with 7zip.

    You will extract files for Odin prince comsey 3.14.1once download with 7zip and will do same for firmware with 7zip .

    Put your model number then region and select check for updates , then download the FIRMWARE , extract the FIRMWARE with 7zip.

    There will be 4 files after you extract the firmware


    BL

    AP

    CP

    CSC

    Each of those files will go in Odin when you open to the corresponding slots

    BL

    AP

    CP

    Home slot don't out anything

    CSC USE HOME CSC FIILE TO SAVE DATA /THIS ONLY GOING BETWEEN CARRIER FIRMWARE OR IF YOUR ON UNLOCKED GOING BETWEEN UNLOCKED FIRMWARE

    If you going from carrier to unlock firmware keep regular CSC not home CSC and do a back up it will factory reset the device.

    connect your phone with cable to computer , once the files are in its slots hit start, once done you'll see pass in Odin and it will reboot





    *Make sure you put phone in download mode
    *If dont see your phone connected in Odin change cables or ports in computer .
    *Never disconnect the cable in middle of flashing.

    If looking for Att firmware can try xda or sammobile as they are hard to come by otherwise flash Tmobile (don't worry) all carriers firmware are interchangeable but might have to flash each security update monthly but as long as u use Home CSC it won't factory reset and only takes 10 minutes like a OTA to complete.

    Seems to have worked! I found an ATNT from March firmware, flashed it, and then all the sudden it had an OTA update and it then it updated to April 1st 2021 Security patch AND i got 3.1 ONE UI and Android 11 now. So im fully up to date. This was a lot easier than i expected. Thanks for the help!
