    Default Netgear LM1200 Hacking and info thread

    Netgear LM1200
    A quectel modem with a qualcomm MDM9607 chip

    IMEI, bands, MEID, pESN, FID and TTL are mod-able on it once you have root
    it is de/re-brandable and pretty much anything can be modded that it does.
    it has an android/linux os on one side and os2 on a triple stacked ubi over ubifs over mtd for the firmware.
    It is a 19 partition layout and has an unlocked bootloader which makes it nice to work with.

    --------------------------------
    To open the ports you need to edit USB_COMP_STR.0 resides in netgear_dat if you are looking at that partition by itself and with the spare it resides at D1F038 without the spare it will be at DF0F38 or in ubi form(on your desktop) its located at 306C18
    if you are looking at it from a full (0-7ff) nand dump, with the spare you will find it at 11130F38 or in bin form without the spare it will be at
    108E9A68 you can also get all ports working by just corrupting that string, such as change it from 55 to 00 or 55 to FF
    or in txt change USB_COMP_STR.0 to
    xSB_COMP_STR.0
    or change its value from CHARGE_ONLY to DEBUG_MODE any of those will get your ports enabled.
