    If I understand correctly, if the Samsung Galaxy S4 (SGH-M919) is updated to either: Android 4.3.X or Android 4.4.X; then a restriction is added to the bootloader - preventing the flashing of older stock roms such as Android 4.2.2 (M919UVUAMDL). Is that correct?

    In addition, what would I need to do in order to remove this bootloader restriction, so that my SGH-M919 (on 4.4.4 - M919UVUFNK2) would then allow a successful flash to an older stock rom such as Android 4.2.2 (M919UVUAMDL)?

    For reference, I have listed the details of my phone below:
    Brand/Series/Make: Samsung Galaxy S4
    Model Number: SGH-M919
    Carrier (Country): T-Mobile (USA)
    Android Version: Android 4.4.4
    Baseband Version (Firmware/ROM): M919UVUFNK2
    Phone Rooted Before?: No

    Also for reference, I've listed all the various SGH-M919 stock firmwares/roms:
    4.4.4 (2014 December) - M919UVUFNK2
    4.4.4 (2014 September) - M919UVUFNH7
    4.4.2 (2014 March) - M919UVUFNB4
    4.3.0 (2013 November) - M919UVUEMK2
    4.2.2 (2013 April) - M919UVUAMDL
