    I have followed the instructions here and continue to get a”fail”

    I recently soft bricked my Sprint Samsung Galaxy S4. Phone shows Samsung Galaxy S4 logo and wouldn’t pass this. Prior to this I did not make any copy of the files so doing a restore from back up is not possible at this time. I don’t care about the data being lost. I only care about getting the phone back up and working.

    I can get to ODIN mode and recovery mode. I had previously flashed it with CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5 using ODIN before the problem started.

    I tried all possible way to get my phone working but still it keeps stick on on Smasung s4 boot screen.

    I tried:

    1. wipe data/factory reset
    2. wipe cache partition

    4. I tried flashing it with L720VPUAMDC_L720SPTAMDC_L720VPUAMDC_HOME.tar.md5 but I get the error that Binary=1 in download mode. Not sure if Triangle away apk will be of any help here to reset the binary counter since I cannot get past the samsung logo at all.

    In recovery mode, my system reads:

    Android system recovery
    KOT49H.L720VPUFNAE

    In ODIN mode, my system reads:

    Product Name: SPN-L720
    Current Binary: Custom
    System Status: Custom
    KNOX Kernel: 0x0
    KNOX Warranty Void: 0x1
    CSB-CONFIG-LSB: 0x30
    WRITE PROTECTION: Enable
    eMMC BURST MODE enabled

    Can someone please help me to fix this issue? I can provide more information if needed.

    Thanks so much.

    I have tried every firmware I can find online and none of them seem to work. As soon as it starts in ODIN the firmware install fails. I followed your steps to the letter and still the same result evertime.

    Thanks a lot man. I was stuck on the black Samsung screen after flashing a corrupted file. Now after following these steps I am unbricked and completely back to stock. Sprint immediately updated me OTA to 4.4 and my warranty is no longer voided. Cheers!
