ODIN keeps giving me errors extracting the TAR file in AP slot. Anyone have any thoughts? I downloaded the file again and used 7zip to extract it. This is unlocked S20 Ultra running current U1 firmware with UI 3.1

    ROM 2.7.7 uploaded
    This update not only effects S20, but also NOTE 20 and S21
    With DUDA update and going forward until I can figure out how to fix MODS, all updates will have stock battery, net speed and clock. This is due to Samsung blocking mods on systemui.
