    This is not my work. It was posted on XDA by AdamOutler. This could come in very handy if you have a paperweighted Fascinate on your hands.

    FIrst off I'd like to say Thanks to RootzWiki for the device. They gave me a Fascinate and told me to do what I want with it... So I made it into a development device. Thanks to RootzWiki for the device!


    introduction
    I'm not kidding when I say UnBrickable. Modifying the OM pins means you can boot from USB, UART or MMC. This makes the phone quite UNBRICKABLE. There is nothing you can do software wise to prevent the device from booting into this mode. We are communicating with the unrewritable, efused IROM on the processor. It's the thing that makes the system on a chip into a "system on a chip".I am here now to tell you how to turn your Samsung Fascinates into a KIT-S5PC110 development board. The KIT-S5PC110 development board is the platform used to develop our phones. There are some differences between this mod and the official development platform. The S5PC110 has a removable internal SDCard and no touchscreen.

    Why would you want to do this? When you plug in the battery and connect it to the computer in "off" mode, then press and hold the power button, it will become an S5PC110 board awaiting download of a program to run. This occurs long before anything like software or firmware enters the processor. This is the IROM of the device awaiting commands or a power on signal.

    Because it is accepting a memory flash, anything may be put onto the device to perform a boot sequence..... Apple iOS (iPhone4 has the same processor) WP7 (mango supports this processor).

    This will be a replacement for JTAG once we are able to make some firmware. How could it possibly be better then JTAG? Let's count the ways....
    1. The only part required is a wire.
    2. No shipping time.
    3. No cost for a box to interface the computer.
    4. Permanent.
    5. Can be done as a preventive measure.
    6. Gives the ability to test new Bootloaders temporarily.
    7. Allows development of the entire system.
    8. Removes worry about flashing and acts as a backup.

    After performing this mod:
    Remove the battery, replace the battery, your phone will connect to the computer via USB and await commands. Otherwise it will pretty much act like a Fascinate. See the Special Instructions section.

    Modification

    You will need:
    1. Get someone who knows what they're doing with a soldering iron. If they don't know what flux is, then they don't know what they're doing. You can send me a PM (or email myusername@gmail.com) or Connexion2005(aka MobileTechVideos.com) NOTE: I do not work with MobileTechVideos.com.
    2. soldering iron - make sure it's sharp, if it's not sharp, then sharpen it, flux it and retin it.
    3. flux
    4. solder
    5. tweezers
    6. A relay (possibly- for the wire within to use as a bridge)


    performing the modification:
    1. tear apart your phone... Make sure to take out your SIM and external SDCard before you do this.
    1A. Remove the screws.
    1B. Separate the top case from the bottom case
    1C. disconnect the display connector and free the camera and button assemblies from the case.
    1D. Remove the mainboard

    2. Perform the mod as follows: Replace the xOM5 resistor from the top position to the bottom position.

    *OR: remove the xOM5 resistor and jumper the center pads of xOM5 to the center pads of xOM0 or xOM3.

    3. reassemble the phone.


    Special Instructions

    • This replaces the battery charging sequence. The normal battery charging sequence can be activated by holding power for 4 seconds.
    • To turn on the device, and operate in normal mode, you must hold the power button for 5 seconds.
    • 3 button Download mode works as usual, however you must not have the S5PC110 drivers installed on the computer. You can use your custom rom menu option, adb reboot download, or use a terminal to "reboot download". 301Kohm Factory Mode JIGs work as well, but you must press power to bypass the S5PC110 mode.
    • To enter recovery mode, press and hold power for 3 seconds, then hold volume + and volume - until SAMSUNG is displayed on-screen.


    Conclusion

    Congratulations. You now have a device which works like a KIT-S5PC110 with an OM Value of 29. Now get to developing some serious custom software. See here for setting up the UART output http://forum.xda-developers.com/show....php?t=1235219

    Just received one of these ModderX... I need a new gun as pen went out on a bionic job...lol. Awaiting my order from the warehouse... Now. THIS is what I call a true MOD brother... lol Also are there any "surprises" in the breakdown I will need as far as replacement parts? The Motos can sometimes require (though mainly cosmetic) these.ie. speaker cover/tape flex wire clips etc. Thanks brother! Peace!
