    I went to sleep one night, next morning I woke up and my Samsung Galaxy Tab S2 9.7, a device in which I have never done anything like rooting on (whatever rooting is), simply refused to turn on correctly. Instead I get the Samsung Galaxy Tab S2 'static' boot screen which then eventually switches to an empty screen with these exact words, or error messages:

    Could not do normal boot.
    ddi : mmc_read failed
    ODIN MODE: (HIGH SPEED)
    PRODUCT NAME: SM-T813
    CURRENT BINARY: Samsung Official
    SYSTEM STATUS: Custom
    FAP LOCK: OFF
    WARRANTY VOID: 0X0
    QUALCOMM SECUREBOOT: ENABLE (CSB)
    RP SWREV: S1, T1, H1, R1, A2, P1
    SECURE DOWNLOAD: ENABLE
    ERROR: Cannot read boot image header
    Can't get fdt
    download mode !!

    And that is all that happens, the device will not boot into recovery mode, it will not let me factory reset, the only combination that actually works is volume-down and the home button, which lets me boot into download mode. Download mode is all I can enter. Nothing risky was ever done on this tablet, I just want my data to be ok. Please help!

    Read [Samsung] How to flash Stock ROM via ODIN. The firmware is obviously gone, so you have to reflash it. (Unless that first line, "ddi : mmc_read failed" means a hardware failure, in which case you need the motherboard replaced.)
