Hello all,

I have a xbox 360 with the following info:

D:2.0.5787.0 - K:2.0.5787.0 (BK:2.0.1888.0) X:8D06-A7DB-87A1-7996


I have not had this unit on xbox live in a long time. It does not even have NXE dash on it. Thanks to everyone's hard work we are able to take full advantage of our xbox360. Please do not flame me, as I have done research on JTAG, XBR, etc. But I still kind of unsure as to where to start exactly. In regards to the JTAG hack. My PC does not have a DB25 connector, what can I do to use USB instead of DB25?


Thanks

YES, your console is EXPOITABLE!
Raed and write NAND (for JTAG) through USB is allowed.

- You need to first identify what version motherboard
- download the jtag pics for that model
- install the wires to read the Nand
- make yourself a jtag cable (LPT is cheapest and easiest, but slowest to read)
- read nand, verify, and save it safely.
- run Xell for your version motherboard, read the fuses to get your cpu key
- install XBR image of your mobo type to the 360

 If you cant find a LPT computer to use then you will need to buy, make or beg someone to borrow either a homemade usb flasher or go through the process of making a programmer for a Pic 18F2455 and then make the usb flash tool... I Believe Grim is selling them, do a search

it is Xenon, one of the original xbox360 that were released. I purchased it back then because I knew this day was coming.


Also, what about purchasing a cygnos360 v2 for USB?

The thing about cygnos is you can leave the original Nand intact but you can never go on Live with that box as it will update and kill the jtag exploit, you don't really need it, not too sure on the usb side of the cygnos though


  You should definately remove R6T3 resistor too as that will prevent the fuses being blown by a MS update preventing you to use homebrew

What are the steps on removing the R6T3 resistor? I thought removing that gives you and error on NXE dash?

your mixing apples with oranges......

read a good copy of your nand.........with the 7 wire printer port(lpt) or usb hookup(going to cost ya) thought
you can also use and infectius2 and the add on...or the cygnos360 v2 more wires to hook up ...but more  options (IMG:style_emoticons/default/smile.gif) if you don't wantsto mess with the lpt or usb....

make sure it is a good copy...then flash it back to the console to see if it works......(good backup check)
then save a copy of that good nand somewhere...

do the jtag hack and boot into Xell..then get your CPU key
now that you have your CPU key you can ...look for the newest program to read the nand with the cpu key...
http://forums.xbox-scene.com/index.php?showtopic=690640

then you can get the cygnos360 v2(onboard nand) or the infectus2(soldered on nand) for using a patched dash
this way the dash is updated and no need to pull  R6T3 resistor else if you chance it online with this off and the update wants to dl to you or even try you will be stuck with E(80)<this is why i said 2 consoles 1 live 1 offline(homebrew) not to say if it did work you close the door for the jtag hack and cant go back once the Efuse is blown
after that you can do the option of the homebrew...once you do the option of homebrew brew---dont do live...that be stupid,you'll get ban or get your gamertag revoked.....course your on your own then....

peace

I see. I wouldn't go on xbox live with the JTAG-enabled xbox360. I have two seperate xbox360 for that. However, where can I get the USB hookup as my pc doesnt have LPT connections? If I can do it without getting a cygnos360 v2 or Infectus chip that would be good.

Also, this maybe a stupid question, but couldnt I just buy a LPT PCI card?

After inspecting one of my older PCs I noticed it does indeed have a 25 pin DB connection on the back, however it has a printer icon next to it. So would I be able to use this for JTAG or is this printer only port?

LPT = Line printer terminal

yes, that's the correct port

awsome, now to find a good LPT JTAG tut, if anybody knows of a good one please link.

Thanks

well i know its a bit off the topic
but i just got a working xenon board that i want to jtag
and i was wondering how could i try to prevent RROD
and another q
i dont have the 203W power supply for now i will buy it later
is there any way to try to dump the nand without it for now?

[Makaveli1337]

Would these resistors be good for JTAG?

If those are not correct ones, if someone could pleaes link the right ones on radioshack as that is where im going to purchase all my parts.


Thanks

EDIT:


On free60.org the picture with the JTAG points for xenon board ( what I have) shows that you dont need any resistors, is this true? Also, what resistors do I need for LPT to write/dump the NAND?

330 Ohm resistor are outdated for the Xenon motherboards.  You should be using switching diodes, 1N4148, also available at Radio Shack.  You need 2 but they sell in packs of 5 or 6 (don't worry, still only about $1).

Here's the wiring I used - http://i.imgur.com/U93J1.jpg

Note that the two diodes need to be wired directly to the motherboard on J1F1 with the black side of the diode towards the motherboard and the red side towards the wire to J2D2.

For the LPT you need five 100 Ohm resistors.  I'm not sure how much power they can handle - I took the smallest from Radio Shack, 1/4 watt, which did me just fine.  Sold in packs of 5, also around $1.

Got it done just like it is in the diagram. Thankyou.
