What can be gained from jtagging the xbox? I googled it but very little came up.
Hey Fellas,
Just thought id start a tech - thread for those of us playing around with x360 homebrew (Hopefully im not the only one).
I finally got my hands on a exploitable consoles, dumped the nand, edited XBR (xbox rebooter) as required, now it is currently flashing onto my nand. (Second time i had to do this now, first time got a black screen but i just realised its got to do with the diodes on my jtag hack facing the wrong way ).
Heres the guide i followed, pretty simple and straight forward.
Pretty straight forward and covered everything.
Tips for soldering the J-Tag interface.
1. KEEP IT TIDY (Ive seen some messes, then they complain it doesnt work).
2. Don't use TOO much solder, otherwise it leaks through the hole and files up on the other side of the board shorting out the on the chasis causing all types of headaches.
3. Keep wires as short as possible.
Pics to come, ill post up sucess/failure after its finished flashing.
Hope theres other people getting in on this so we can bounce ideas
Just having a play with xbr at the moment, going to change everything over to cygnosV2 when they come in stock.

Homebrew/ Linux / Some people are playing unsigned code of USB HDD
On the way to xbox media centre.
You can freely change the region codes of games, can you not? And the Yaris patch for XBLA games?
Could you outline to us how you went about getting a jtag-able unit? I would think it would be very hard to find one now days? What to look for, what NOT to look for etc?
Thank you.
I picked up 4 Jtag-ble units today.
Brand new retail
Just look for consoles that were made towards the start of this year
Waitiing on stock fo cygnosV2 to install onto these though.
I've done the JTAG exploit on my Xbox 360, can't wait for the software to make this worth while.
It wasn't as hard as I expected, this was my first soldering job and all I can say it watch a few Youtube vids, get the right gear (don't try and make do) be patient and double check everything.
So can any of these run XBMC yet?
No XBMC that I know of yet, but MAME and other emulators are running, and you can run the games from an attached USB hard drive which is kind of neat.
I'm about to install a Cygnos V2 chip in mine to run freeboot. XBReboot is buggy as all get-out at the moment.
Main PC: INTEL CORE i7 4930k | ASUS P9X79-PRO | 16GB G-SKILL 2400MHz RAM | GTX 780 3GB PHANTOM GLH EDITION | SAMSUNG 840 PRO 256GB | 2 X 1TB WD RE4 | 2TB WD GREEN | SILVERSTONE STRIDER 1200W GOLD | HAF-X w/ DEMCI FLEX FILTERS | SWIFTECH H320 AIO | WINDOWS 8.1 PRO w/ MEDIA CENTRE x64.
When they get XBMC to run properly on a 360 then i may retire my original xbox's although the 360 looks a little dicky to me.
No need to bother with the xD mod or a Cygnos mod chip, a new version of XBR is out which fixes all these issues and doesn't require you to manually patch your xex files.
To quote their readme:
"* What went wrong?
Earlier versions of XBR used the same CB/CD pair to start the 8955 kernel as the exploit. Freeboot, using a dual nand setup, used the older bootloaders to start the exploit, than used the newer bootloaders on the alternate flash to start the kernel.
The problems were not related to the patches used by XBR, but rather the use of the older bootloaders. Please try to control yourselves if problems arise, they can always be fixed. Dont do anything crazy like start conspiracy theories, buy a cygnos, wire up a dual nand or xd card, rip out a big nand to swap in a smaller one etc, etc. Have a little patience, have a little faith :P "
Flashed my 360 with this update, so far so good.
Once you've used a Cygnos you won't go back to toying with LPT ports, which can be effected by interference, timing issues etc.
Had a customer bring in a "bricked" console today.
Spent about 4 hours getting it good from his crappy LPT port dumps.
Installing a Cygnos to flash made the whole process alot easier and faster
Wasn't the cheapest repair job, but he was still happy he didn't loose his exploitable console.
Cygnos v2 does own the JTAG LPT method imo, considering what you can do with the 360, the JTAG is a monstrosity of a mod, even when done cleanly.
I'm sure/hoping you won't mind urban_s0ulja but how can anyone not want such a clean and swift install?

I'm not disagreeing that the LPT method sucks but why don't more people talk about Gentoo live with lflash program? Once you've firmware upgraded it once you can then do it from the console itself :-)
I have been seriously considering a Cygnos but I don't see the value add for myself, especially as the JTAG and LPT hacks were at the limit of my soldering abilities the mod chip plus fitting seems expensive IMO anyway.
Why is there only 2 wires in that pic? According to the install guide it should end up more like
EDIT: Oh thats one of the old RevB chips that don't have JTAG built in.

Whats the go with this, I thought the exploit was on the way to running XBMC. Is this video fake? [ame=http://www.youtube.com/watch?v=biCZJNFV8nI]YouTube - XBMC running on Xbox360/Ubuntu - by Team Cygnos[/ame]
Or haven't they released the modified XBMC code ?
That's a pretty old video, using the KingKong Hack and all. Anyway Team XBMC don't seem interested in porting, someone might take up the challenge though I guess.
