I've built two of these, and neither works.  I've tried them with 2 different drives.  If I create a loopback on the computer between the tx and rx wires, I get random gibberish in terminal.  However, if I make the loopback with the tx wire and end of the probe, I don't get anything, and when I connect the txt to the Base on teh Transistor (to bypass the resistor at the end of the probe) I also do not get anything in terminal.  It appears data cannot pass through the transistors.  When I hit the r707 hole with the probe, I do not get anything in terminal, and also jungle flasher says "bad serial data".  I've got the tranistors the right way.  I tested both transistors with an ohm meter and could not get anything on the meter when testing the base with either the collector or emitter.  This was before I made them into lite-on probes.  Could I have gotten two bad transistors from radioshack?  They are MPS2222A NPN Transistor.

I'm not an expert, but I've got some soldering experience under my belt, and I'm confident it's not my soldering skills that are at fault. I'm powering the drive through the xbox, 5v from the computer molex (I tested it and it is 5v) and I've grounded the xbox and computer chassis together. I used all new components from radioshack.  I've also tested multiple probe heads to make sure I could probe the tiny hole correctly.

Any ideas?

Can't you just use the 5v point on the drive's pcb for the CE circuit? Does it have to be from molex/batteries?
Also, when powering from the 360 for the drive, remove the ground pin (pin9), or the eject/close pin (pin3)?

thanks a lot!

Ok, I'd like to do this mod and spend the money buying stuff like the soldering iron which I can use later in the future for other things.

I've solder lots of things before but just don't have a soldering iron anymore due to a move and having my stuff back in Cali.  

Anyway as I first read in the beginning and correct me if I'm wrong, instead of doing this project on a serial plug, you can do it on a USB plug?

I have a newer laptop with no desktop so I don't have access to a serial port.  Or can I just buy a serial to USB adapter at Radio Shack?

If so where's the tutorial to do this with a USB port?

I've read though the first handful of pages and got tired of reading every post.  Just wanted to see if someone could just point me in the right direction please.  I can read and follow the instructions afterward.

Thanks!

Wouldn't it be easier to use something that's a bit newer than two years old?

mra.  if i had the choice of this or that, i would mra every day.  only needs a resistor and a scrap of wire.

Sorry, I'm a noob and don't know what your ancroynm stands for or what it is.  I love the idea of being easier and using a resistor and wire scrap sounds great.  

Could you please point me in the right direction???

Basically I want to upgrade the firmware without having to buy the xecuter or anything else.  I can solder, I have a soldering iron and can easily go to Radio Shack to buy the parts to do the stuff needed to do the upgrade.

I'm pretty sure I'd save a good amount if I could do it myself.  Now if there's really no option then of course I'll buy what ever is already premade out there to do it.

Please, just looking to get pointed to the right direction with hopefully links.

Quick question about the DIY probe. I have a USB TTL device I used a while back on some other stuff and want to know if I could use that to get the data from my drive. Would my USB TTL device be able to do the same thing as making the probe?

I looked at the diagram for the probe and it has an Rx, Ground, and 5v lines. So does this so I imagine it would work.

Here's an image of what it kinda looks like:

which liteon model?
if 93450 take a look in my sig (or boxxdr method)

I finally noticed the FW number and yea it's 93450c

No, you'll need to boxxdr/MRA

Im so glad I found this thread. Just come to flash a Benq drive or so I thought, JF said it was a liteon, When I looked at the drive sticker it was a liteon. I anded up making a probe from an old compass, some resistors from a TV power supply and a BC639. I had a serial cable from a megasquirt project I did a few years ago. Works a treat

Or you can get the 5V from the drive itself ..., works fine to
