    I have tried to root my Galaxy S7 SM-G930F using CF Autoroot. The Odin log seems to show that all is well but the phone will go no father than the two opening screes. Full details below:

    Procedure and Odin Logs

    1. Odin 3.0 started OK in Administrative Mode
    2. Phone set into Download Mode (warning screen) and then Vol-up key pressed to enter the Download Mode
    3. Phone connected to laptop running Odin and blue windows in ID ROM field signifies that the phone is recognised and connected. Log shows added.
    4. Pressing Options shows that AutoReboot and F.Rest Time are selected.
    5. Box next to AP selected and then AP is selected.
    6. A browser window appears, file CF-Auto-Root-herolte-heroltexx-smg930f.tar.md5 selected and opened.
    7. Log Shows
    <OSM> Enter CS for MD5
    <OSM> Check MD5.... Do not unplug cable
    <OSM> Please wait….
    <OSM> CF-Auto-Root-herolte-heroltexx-smg930f.tar.md5 is valid
    <OSM> Checking MD5 finished successfully….
    <OSM> Leave CS
    8. Start key pressed.
    9. Log shows
    <ID0/005> Odin Engine V(ID3.1005)
    <ID0/005> File analysis
    <ID0/005>Setup connection
    <ID0/005> Initialization
    <ID0/005> Get PIT for mapping
    <ID0/005> Firmware update start
    <ID0/005> Single download
    <ID0/005> Recovering img
    <ID0/005> NAND write start
    <ID0/005> cache img
    <ID0/005> ROT closed
    <ID0/005> RES OK!!
    <ID0/005> Removed
    <ID0/005> Removed Port 0
    <OSM> All threads completed. (Succeed 1/Fail 0)

    The phone restarts and shows 2 screens.
    Screen 1: Samsung Galaxy S7 and below Android
    Screen 2: Samsung (pulsing in brightness)

    The phone will now only respond to a power-off using "Vol-down + Home + Power". It can be restarted using the "Power key", "Vol-down + Home + Power" (Download Mode) or "Vol-up + Home + Power" (Recovery Mode).

    It consumes a lot of battery and gets much warmer than usual.

    The Recovery Mode Screen Shows

    Android Recovery (yellow font)
    Samsung heroltexx/herolte (yellow font)
    7.0/NRD90M/G930FFXXU1DQHC (yellow font)
    User/release keys (yellow font)
    Use volume up/down and power (yellow font)
    Reboot system now (blue font)
    Reboot to bootloader (blue font)
    Apply update from ADB (blue font)
    Apply update from SD card (blue font)
    Wipe data/factory reset (blue font)
    Wipe cache partition (blue font)
    Mount system (blue font)
    View recovery logs (blue font)
    Run graphics test (blue font)
    Power off (blue font)

    The Download Screen Shows

    At the top left hand corner
    Odin Mode (Red font)
    Download speed fast (Red font)
    Product name: SM-G930F (White font)
    Current Binary: Custom (White font)
    System Status: Custom (White font)
    Secured Download : Enabled (Blue font)
    Warranty: Void (Brown font)
    RP SWREV: B:1 S:0 K:0 (Brown font)

    Further down it shows
    Large Down Arrow
    Downloading
    Do not turn off target

    As I am very new to rooting it may be that I'm missing something extremely simple or it may be that i've made a complete ****-up.

    Please can you help me?

    1. Did you check CF Autoroot to make sure that it says it will work on your model S7 (the F model with the D7 ROM)?

    2. The only thing you can do right now is reflash the stock ROM. You can find the ROM image at https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/ You can find the full procedure for flashing it at [Samsung] How to flash Stock ROM via ODIN.

    Also read the https://forum.xda-developers.com/gal...-odin-t3369431 thread. (You can use any country's ROM, but change the CSC or HOME_CSC [the first wipes your data] to one you extracted from a ROM for our lamguage.)

    And read https://forum.xda-developers.com/gal...-root-t3337353 to root.

    And use Odin 3.12. (If you can find the PrinceComsy version, it bypasses the SHA256 check, so modified ROMS will pass.)
