How to JTAG your Xbox 360 and run homebrew

Step 10 My avatar is only a silhouette!

Usually your avatar will be a blank silhouette and it will tell you, you need to install an update to use them.  All you need to do is download this update file, and place it on a USB flash drive, and plug it into the back usb port of your xbox.  Your 360 should detect it and install it.  Make sure you extract it first and the root of the drive is the $SystemUpdate folder.  You can also burn it to a CD to update.

If you're paranoid you will brick your console because microsoft is out to get you and ruin your homebrew, you can look at the picture about removing the r6t3 resistor to keep from having your fuses blown.

I also provided a mediafire mirror in case the microsoft one goes down.

So by doing this: 1.Can we still play games online? 2.What happens when we remove that resistor? I'm really curious please help

[ryguy425425]

1. Yes, but only for a short period of time. It could be 1 min or 3 months.

2. The J-Tag exploit was closed with a dashboard update which blew a fuse on the motherboard. Removing the resistor means the fuse can't be blown, keeping the J-Tag exploit open.

If the fuse is already blown couldn't one just use a bit of solder to join it back together? Or is it something that may damage the system. I remember having to do something like that on a 360 reciever to get it working again. I suspect since it was an intentional software fuse blow then it must not have been too important. The reason I ask is if you did join it would it make a jtag available to newer kernels since there is no fuse to blow and the connection is still there?

The fuse is an internal one, built into one of the microchips. Very very tiny. With an electron microscope, you might be able to see it, but there's no practical way to fix it.

They put fuses like this into microchips for security reasons, as you can see!

[ryguy425425]

I believe it is a virtual fuse, and I want to say it effects the bios. The only real answer I have to that question is that if it was that easy, it would have been done already (and it hasn't). I hope that helps.

You can find more info about removing the R6T3 resistor here: http://www.free60.org/R6T3

Important Note

- The removal of R6T3 will cause an E80 system error if the NXE update is installed.
- Replacing the resistor with the original or with another 10K Ohm resistor usually fixes the error state.
- Given the difficulty in surface mounting a resistor as small as R6T3, simply holding a 10K Ohm in place while the 360 is powering up after giving a E80 will typically allow normal operation from then on.
- Care must be taken not to bridge the gap without a resistor in place as this may cause system damage.

when you temporarily put the resister back in does it blow the fuse

I updated with FreeBOOT to the new kinect dash but i cant get any of the avatars to apear. is there a manual way to update them with the file you have?

-Thanks!

[sebastimau]

u are awesome. thanks worked great. Kinda of scary doing the soldering but it worked fine

[supernova12]

You need some kind of memory unit to store the profile on, or else the xbox has nowhere to put it! So just put in your normal xbox hard drive to create the profile, you can always transfer it later.

_{easy to follow with good diagrams. I'm now the proud owner of 2 JTAG beast's :)}

_{One question though.. is it safe to update my dash to the file you've linked? Won't that destroy the JTAG or is it only updating past 8955}

[CowGuy]

 The file I included is a dash update that is actually a lower version then what you are running and it won't touch your kernel, it just takes the avatar files from it.  If you wanna be extra sure you can remove the fuse I talked about in the gyide.

[maru487]

I can't get past or skip the initial setup. It asks for language, video, etc, and then when i get to create profile it won't let me skip it, and asks for a memory unit. I have a 3.5 hard drive attached and also tried a memory card in all three usb ports. It still wont continue.

Any help would be great  :)

[CowGuy]

I'll try to replicate your error by removed all my storage and resetting the box, but for now have you tried removing all kinds of storage including the hard drive?  I remember I set mine up without anything attached and it worked fine.  It probably can't detect the hard drive since you need to get to the dashboard to format it properly.
