Directions:

- Add Probe to 5

- Remove straight wired connection from 6 and replace with toggle switch

Items Needed:

   Stock DVD Drive Power Cable (or buy one here for $2.40 shipped)

   Switch and wires from old computer build; front panel (or buy some wires here for $3.60, without the
           switch. Radioshack should have a decent switch available.)

        Power Switch with attached wires and connectors (removed from plastic housing)

        Wire from front panel peripherals (x2; one side of one wire stripped)

   Leg of infrared LED (or any small, electrically sound, metal object to use as a probe. A pin or needle would
        work as well)

Tools Needed:

   Small flathead screwdriver or thin metal pry bar

   Electrical tape (just in case)

Completely solderless DIY Pogo Mo Thoin Probe.

I made one out of old parts, and it worked a million times better than cutting traces and soldering the PCB (MRA Hack). I'm going to order an extra cable from DealExtreme ($2.40, free shipping takes about a month to arrive) to make a permanent (ie. extra, soldered) version I can use to swap out and update firmware. The switch will be especially handy when updating, letting you power on/off the drive as needed.

I started out by disconnecting the [5] and [6] wires from the plug. The easiest way to do this (just like disconnecting the plastic housing on your front panel wires) is to pry up the small flap of plastic above the wire and pull it out. For the [5] wire, I used a long piece of wire for the front panel speaker, with metal connectors still attached. These connectors fit perfectly into the DVD power cord plug. I jammed the 'probe' (the LED leg) into this connector as well as the spliced end of another length of wire (with the connector also attached at the other end), creating a very snug fit with very little wiggle for the probe. Insert the opposite ends of your new probe wire into the [5] slots. The same was done with the [6] wire. It was removed and replaced with the power button switch. I checked all connections and the switch with a multimeter and recommend you do the same.


Update (3/10/12):

After receiving my extra DVD power cable, I went ahead and made an improved, soldered, easier to use, permanent version of this probe. The steps were exactly the same as above, but I soldered on a toggle switch from an old flash bulb, along with a green LED indicator light so I can tell whether the probe is on or off. I used a cardboard spool from some old thermal paper I found at work for the body, and closed everything up with some epoxy putty on either end. Here's my end result..

How to Easily Update Firmware

No-Open Xbox 360 Firmware Updating

 Remove the upper metal sheeting from the top cover. To do this, use a dremel tool and cutting disc to quickly cut away the two melted gobs of plastic holding the sheeting in place. Pull up and remove.

Now all that's needed to do is add a couple SATA wires to the board. Connect a one foot long, 90 degree SATA cable to the board. Attach the Male end of a Male to Female SATA cable to the other end. Connect the Female end to the drive.

 Now all that is needed is a little rerouting of the wires beside the left side of the drive so that the M to F connection is outside the main enclosure, to the front left (where the hard drive will be sitting). Carefully put everything back together and you should have easy access to the Male SATA plug by just popping off the hard drive and the plastic cover.

How to Fix a Jammed DVD Drive Tray

I managed to fix my jammed DVD drive tray by opening the console, removing the drive, as well as the top and bottom metal housing. The drive was sticking and needed to be nudged every time to open properly, which was becoming a pain. A bottle of alcohol and can of WD40 was all that was needed. I cleared out all the dust, lubed up most the moving parts (only avoiding the drive belt, that wouldn't be good if it got greased up). The ejection bar was the problem, I think. Dirt mixed in with the stock grease (which by now is 4 years old) and made it difficult to lift the laser mechanism up to the disc, and release the tray. There are a few access holes that I swabbed with a WD40 soaked Q-tip, letting the excess flow down where it was needed. I manually ejected a few times by pushing the ejection bar horizontally and it seemed to loosen right up.
