Flashing always makes me a little nervous. Often when I update BIOS on Dell computers, I anxiously hold my breath, cross my fingers and hope for the best. I have never had any issues yet, but all the same, flashing BIOS, ROMS, or anything for that matter makes me nervous.

So anyway, I have a customer who brought in their older xBox 360 that is no longer reading discs. Initially I just assumed that I could replace the disc drive for him, no big deal. Well, as it turns out, Microsoft doesn’t want you to do that. In fact, they take strong measure preventing users from repairing xBox 360′s all together.
In order to replace the DVD drive on an xBox360, it requires flashing. That is, unless, you can find the same exact disc drive and swap out the circuit boards. The repair is actually quite easy. The only risk is if the disc reading error isn’t the laser but instead the circuit board itself.
All you have to do is disassemble your xBos 360, gain access to the DVD drive and remove it, and open the DVD drive case up. From there you need to make note of the six wires soldered on the circuit board. On the DG-16D25S model, shown above, there are two yellow wires, two white wires, then one read wire and one black.
Cut the wires about an inch from the circuit board. Remove the two screws from the circuit board and then remove the circuit board from the case. Next, cut all six wires on the replacement DVD drive and then remove the two screws securing the circuit board and then remove it from the case.
Install the original circuit board in the case of the replacement DVD drive. From there, heat up your soldering iron and proceed to re-solder the wires back together. Tape them all with electrical tape, or better yet, use shrink tubing. Secure the DVD drive case lid and then hook up the sata port and power supply. From there remount the replacement drive back in the xBox 360 and then proceed to reassemble the xBox 360. After all this, you will have successfully replaced your DG-16D25S xBox 360 DVD drive without flashing it by simply using your existing DG-16D25S circuit board that’s already validated with your xBox 360 system.
