    I'm hoping someone here can help in explaining this because this is something I've NEVER seen or heard of before and in theory, shouldnt be possible but i'm seeing it with my own eyes!


    I'm (about to) purchase a slightly used Samsung Galaxy S CAPTIVATE model (SGH-i897) at least that is what the "boot up screen" shows.. I KNOW this is the Captivate.. i've seen the physical differences between it and the Vibrant.. they are basically the same phones hardware wise but do have a different physical appearance on the outside.. the Vibrant's model is GT-i9000..

    now when I go to the "About screen"...the model shows the GT-i9000! How is this possible? I'm baffled because I know that i'm actually looking at a CAPTIVATE and the boot up screen shows the correct model number..but the android os (which shows the gingerbread 2.3.5 model in the about screen) is showing the model number as the VIBRANT.. gt-i9000, on the same phone!

    I want this phone and was about to buy it but i'm thinking this could seriously cause problems when i go to root and mod it as the conflicting model numbers could create problems with the proper files and processes i'll need to follow when doing the root/mods...

    Has anyone heard of this or can explain this because I am STUMPED!


    THanks

    I looked at the About screen again and the KERNEL VERSION looks like something that is NOT the stock kernel. It states:


    2.6.35.7-I9000XXJVT-CL617736
    ficeto@beast #DarkCore_4.1_JVT_C


    this has to be a custom Kernel right?
    This phone must have been rooted and mod'd at some point (the seller didn't know and thought his cousin only unlocked the phone).


    I assume a custom kernel that likely is typically for the Vibrant GT-i9000 was flahed with or without a custom rom to this phone and that is why there is the conflicting model numbers... this make sense?


    Normally that wouldn't be good idea to use another kernel or rom for a slightly different model of phone but i guess it worked..

    I would now like to confirm that this is the case and if so, that it is obviously ok..cuz the phone is working fine.
    Should I now wipe the phone back to stock rom/kernel? Can I? if I want to do more mod'ing on the phone anyways.. different kernels and likely update os to ICS 4.0

    Thanks for any help on this and hopefully this all makes sense now and explains what i'm seeing

    From what I can find, that does appear to be a custom Galaxy S kernel. I don't know if that one in particular was meant for the Captivate. I have seem ROMs that said I9000 on boot, but ran fine. I think maybe the devs port them and just don't change the boot animation/about info.

    Either way, you should be fine buying the phone. One nice thing and the Captivate is that you can always go back to stock using Odin. There are multiple versions of the Odin one-click (for different versions of android), as well as full version for flashing kernels, modems, etc. So, I recommend reading up on it on xda a bit before you use it.

    xda has a list of stock ROM one-clicks here:
    [Stock ROMs](OneClicks Master Collection)+[Kernels (Stock & w/ CWM)]+[Modems] UPDATED - xda-developers

    It is possible.. in fact you can change it to what ever you like. It is just how the phone represent itself to other applications. The phone was not stock (probably running Mosaic rom) or if it was the kernel was updated to a custom DarkCore kernel.

    This kernel build comes from the i9000 and was ported to the Captivate since they are very similar hardware wise. The kernel update modified the original build.prop file located in /system. The original build.prop would have contain the SGH-i897 text refering to the phone version. The kernel build.prop file replaced that info with GT-i9000.

    You can also have different kernel boot image reporting different version. My Rommed cappy now flash a GT-i9000 screen followed by a SGH-i897 splash before the boot screen.

    Having the phone build.prop show a different model should not impact how the phone works. It is only a file configuration issue.
