Now that your motherboard is prepared for flashing, you'll need to actually flash the TSOP chip. Unsuccessful soldering results in an error when flashing the TSOP chip, so if you encounter that error just attempt to solder the pads again. If you are unsure you can always put back together your Xbox, and continue with this guide. It can be hard to tell if you successfully made the connections. The solder pads are very small, but if you're patient and careful you should be able to heat both of the pads, and apply a little extra solder until the two pads are connected. You'll need to solder the R7D1 pad to the R7D2 pad, and the R7D10 pads together. The image above shows the locations of the pads.

Most consoles require this same modification (any console from revision 1.2 through revision 1.5). In the case of my revision 1.3 console all I had to do was bridge two pairs of solder pads. The process of preparing your motherboard depends on the revision of your console. You will need to modify the motherboard to disable write protection on the TSOP flash chip.

The second method is a hardmod, which requires a physical hardware modification. The first, and easiest method is a softmod. There are two types of mods you can do to run homebrew on your original Xbox.
