  5. Hi Jayce,

    I am Using Samsung Galaxy S2. Recently i changed to ICS 4.0.3 from Gingerbread 2.3.4.

    Here is the new config:

    Model Number : GT-I9100
    Android Version : 4.0.3
    Baseband Version : I9100XXLP1
    Kernel Version : 3.0.15-I9100XXLP2-CL57619 se.infra@SEI-44 #3
    Build Number : ICS.XXLP2.

    And i tried to change to Cyanogenmod 7. (http://www.cyanogenmod.com/). i downloaded all the files and without unzipping saved it to internal SD and tried to reboot (up volume key+home+power)…

    Here is the problem.. im unable to install the files. πŸ™ i dont see any “advance” in the boot up screen.
    here is the list that i can see in download mode.

    reboot system now
    apply update from external storage
    wipe data/factory reset
    wipe cache partition
    apply update from cache
    test redbend fota(FS)…

    and while connecting USB in boot mode, nothing is happing to Odin,. (no yellow in first tab)…

    Can you please help me out to install new ICS 4.0.4, CMD9…

  7. Hi there,

    I am using ICS 4.0.3, i have i USB JIG and i want to use it to reset the flash counter and get rid of the pesky triangle.

    From what i found on your great website i understand that i will have to flash the ‘old’ gingerbread bootloader to get the JIG working with ICS.

    I am using this ICS rom I9100XWLP7_I9100XXLPS_I9100XENLP3.

    I have two questions
    1) Will the ‘old’ gingerbread bootloader work with the above mentioned rom?
    2) Were can i find the original ICS bootloader to bring my phone to its initial state in case i need to claim guarantee.

    Thanks in advance for your answer

  12. Hi Jayce,

    Just a quick question ..
    I updated my SGSII with the I9100XXLPQ but later found the version for my country viz I9100GDXLP6 but I was unsuccessful in many attempts to change from the XXLPQ to the GTXLP6.

    Any tips on how I should go about this (btw I have change from Odin 1.85 to v3.04 without any success either!).
    Will appreciate a pointer to the correct direction in which to look/proceed.
