REMOVAL OF THE EEPROM CHIP:
You will need the following things:
1. Fine Tipped Soldering Iron (at least somewhat fine)
2. Fine Desoldering Braid
3. Magnifying Lens/Microscope (Preferable, but not needed by pros)
4. Solder
5. Flux
6. Fine Tipped Tweezers
STEP 1: De-solder EEPROMs from both source and destination Xboxes
a. Once you locate the EEPROM be sure to make note of the circle shaped indent in one of its
corners.
This marking is to identify which way the chip should be placed over the pads (you don't want to
put it in backwards later on).
b. Set up your magnifying lens or microscope over your Xbox motherboard
c. Use the desoldering braid to remove as much solder as possible from each of the pads under the
chip's legs. Beforehand, it's wise to apply a bit of flux to the pads to aid in solder flow. If you can
adjust the heat on your soldering iron, try using a higher heat of around 800, since the higher heat
will make it easier for the braid to absorb the solder more quickly. Using tweezers hold the
desoldering braid over the desired pad and press (not too hard) on the braid with the soldering
iron. Once you have removed as much solder as possible from the legs and pads and things look
as clean as can be, it's time to remove the legs from the pads, one by one. Place the tip of your
fine tipped tweezers (or a suitably small piece of metal) in the space between the leg and the chip.
Using the tweezers as a lever, lightly nudge the leg off while heating the pad with the soldering
iron. You don't want to bend the legs very much, so be sure to be gentle when removing them
from the pads.
Try to nudge them just enough to see or feel a slight movement, indicating that the leg is no
longer connected to the pad. Continue this process with each pin until all 6 are removed
from the pads.
STEP 2: Solder EEPROM onto Motherboard
Now that you have your EEPROM removed, it's time to solder it onto your motherboard. The first
thing you need to do is prepare each pad with a little bit of solder and flux. Only use a small
amount of solder on each pad, trying to keep it relatively flat and level (not all blobby). Using
tweezers, position your EEPROM over the pads, making note that the circular indentation
mentioned earlier is in the correct place. Once correctly positioned, use the soldering iron to apply
some heat to each of the opposite corner legs, one at a time. This will hold the chip in place while
you solder the rest of the legs. Once the chip is held in place, you can solder the rest of the pins
on, adding solder and flux to each one for a good connection. To finish things up, you can add
some solder and flux to the two corner pins.
That's all. You can now recover those memories, once thought lost, from your locked hard drive.
Remember, when booting your XBOX only the locked hard drive you were trying to recover will
boot. Any other hard drive will need to be unlocked to boot up.
