    Issue with firmware G920FXXU4DPGB... Cannot roll back... HELP Please!!!

    Hello,

    This morning, I have downloaded the G920FXXU4DPGB_G920FFVFW4DPG3_VDC firmware for my G920F... This is not working (so far no problem). Then I tried to roll back to my previour firmware, but then I have a FAIL message in Odin and a read error on the phone...

    I am stuck with a phone without firmware... HELP please!

    I saw that this firmware has been removed from the site this afternoon, hence I guess I am not the only one facing the issue... Any idea on how to solve this?

    Any help and way to solve this would be greatly appreciated!

    Complementary info :

    On Odin here is the error while trying to restore my previous firmware :

    <ID:0/009> Odin engine v(ID:3.1101)..
    <ID:0/009> File analysis..
    <ID:0/009> SetupConnection..
    <ID:0/009> Initialzation..
    <ID:0/009> Get PIT for mapping..
    <ID:0/009> Firmware update start..
    <ID:0/009> SingleDownload.
    <ID:0/009> boot.img
    <ID:0/009> NAND Write Start!!
    <ID:0/009> cache.img
    <ID:0/009> cm.bin
    <ID:0/009> FAIL!
    <ID:0/009>
    <ID:0/009> Complete(Write) operation failed.
    <OSM> All threads completed. (succeed 0 / failed 1)


    I tried also Odin 3.10.7, same error. I also tried another working firmware, same error.

    On the GSM, I see a RED info : "[CM] SW REV. CHECK FAIL. DEVICE: 4 BINARY: 3

    I hope this will help to give light...

    This firmware is not on Sammobile.
    Did you download it some time ago?

    The problem may be that the bootloader installed and so you now cannot downgrade.

    See if you can put your phone in download mode and install your firmware with SmartSwitch using your phone Serial Number:

    Hello,

    1st of all Thanks for your reply!

    I downloaded the xxxGB version from this website yesterday morning. It was on the website at that time, even if it disappeared in the afternoon... And also strangely the firmware list for July is no longer in chronological order...

    For my issue, I think you got the problem : there was an update of the bootloader, hence a downgrade is no longer possible.

    I have tried, as recommended, the SmartSwitch firmware recovery. Unfortunately at the end of the process, I have the same error on the screen :
    "CHECK FAIL. DEVICE : 4 BINARY : 3" in red... And also an error message in Smart Switch advising that the recovery process failed.

    Not looking good! Any more idea???

    Looks like you are going to have to wait for the update to return, and hopefully any issues in it are resolved.
