    Galaxy A7 2018 (SM-A750GN/DS "Could not do normal boot, Invalid Kernel Length

    Hi Hi:

    My Samsung Galaxy A7 2018 SM-A750GN/DS can not turn on now!! The top right hand corner on the phone's screen shows the wording : "could not do normal boot, invalid kernel length". I tried the firmware that downloads from [ Login above or register to see download links. ] (the firmware version is: AP_A750GNDXU6CTF1_CL18671722_QB31777375_REV00_user _low_ship_meta_OS10.tar.md5 ). Then I used Odin3_v3.09 to solve the problem but showed "Failed". It doesn't work!!

    In Odin3, I clicked "Auto Reboot" and "F. Reset Time" only. Then clicked the "AP" to find the file AP_A750GNDXU6CTF1_CL18671722_QB31777375_REV00_user _low_ship_meta_OS10.tar.md5, and then I wait for a minute to click : "Start" when it was ready.

    In the Message box, it showed as follows:
    <ID:0/007> Added!!
    <OSM> Enter CS for MD5..
    <OSM> Check MD5.. Do not unplug the cable..

    <OSM> All threads completed. (succeed 0 / failed 1)

    Do I need the PIT file? Where I can download the PIT file for SM-A750GN. Please help!!

    What happened to my device: when i turn on my phone, the phone was very lag. Then i restart the phone after a few minutes. After that, i can't turn on my phone again, and there is a sentence writing : "could not do normal boot, invalid kernel length".

    This device has 64 GB and has used about 36 GB: Have install about 30 apps ; about 6 GB for photos, 5 GB for about 30 videos, half GB for documents or PDF files.

    Have five files such as:
    AP_A750GNDXU6CTF1_CL18671722_QB31777375_REV00_user _low_ship_meta_OS10.tar.md5
    BL_A750GNDXU6CTF1_CL18671722_QB31777375_REV00_user _low_ship.tar.md5
    CP_A750GNDXU6CTF1_CP16010487_CL18671722_QB31777375 _REV00_user_low_ship.tar.md5
    CSC_OMC_TGY_A750GNTGY6CTF1_CL18671722_QB31777375_R EV00_user_low_ship.tar.md5
    HOME_CSC_OMC_TGY_A750GNTGY6CTF1_CL18671722_QB31777 375_REV00_user_low_ship.tar.md5

    I flashed the "AP" only.

    You always should flash ALL 4 files! I don't hope you bricked your device by this

    Flash AP BL CP & CSC_OMC (NOT HOME_CSC): your device will reset afterwards
