No it doesn't. This is why everyone was told not to update if they want a chance for homebrew.

 well they spoke a little too late.


They should of went and got the Beta from Major Nelson and alert people early

Some features of the new Cygnos360 V2.0

- downgrade Xbox360 (production before August 2007 and non-HDMI)
- switch between the kernel on your Xbox360 and the kernel on Cygnos360 V2 (for example for region-code switching or switching to homebrew/exploitable kernel)
- no lifting of CE-pin or cutting of traces neccessary
- protect your data by storing offline information on the Cygnos360 V2 NAND-flash and avoid banning (dirty-NAND concept)
- directly downgrade on the Cygnos360 V2 NAND-flash
- easy quicksolder installation of Cygnos360 V2
- Cygnos360 V2 firmware can be up- and downgraded to any version in the field
- built from high quality components
- downgrading takes 1h15m on average on a middle-class PC
- reading from and writing to flash takes less than a minute each
- easy to use
- a reliable solution for downgrading (Xenon mainboards)
- run Linux (Xenon mainboards)
- read and flash your Xbox360 and Cygnos360 V2 NAND-flash in less than one minute
- Infectus is no longer needed for any of the functions

I didn't ever see that USB solution, I like that a lot. The only downside - no dual NAND. Thanks for that link. I knew USB to parallel adapters were out of the question (at least from the admittedly small amount of reading I've done), but that looks pretty easy.

* XeLL
Since our microcontroller cannot handle serial communication at 115200 baud, we had to make a minor modification to XeLL. The modification will set the baud rate register of the Xbox 360 to 38400 baud, 8 data bits, no parity and one stop bit.

38400 baud
= 288.00 KB/min
= 4.80 KB/s
= 38.40 Kbps
= 4.69 KiB/s
= 17.28 MB/h

NAND sizes are about i dont know... 21- 25 MB

If you ever had to copy your own dreamcast games during the early stages youd know all about baud. (Or if you had a slow modem wit AOL)

Well, you could have always worked out how to hack it yourself  

Seriously, let's not get into that again, anyone who downloads the latest updates in the first week isn't really a 'hacker', and if you really are one, then buy a 2nd hand 360, they are cheap and you need a second one anyway if you want to continue using live, new games etc. etc.

/facepalm...nice try trying to correlate those two.

1- The 38400baud is for comm over the JTAG/serial interface NOT for writing the flash, so the speed difference isn't really noticeable unless you're using XeLL to dump LARGE amount of data over the JTAG port.
2- 360 NAND size is 16MB (unless you've got a fancy new Jasper with 256 or 512MB, but Cygnos doesn't work with those yet)
3- The 1h15m on a good PC is just the time it takes for the PC + 360 to work together to go bit by bit down the key exploiting a timing issue with the memcmp function to essentially intelligently guess the CPU key.

Downgrading is obsolete, they dont even have it in the manual anymore.

all you need to do is build the right image for your mainboard type (xenon, falcon...) flash it onto the NAND (less than a minute) and then you can start your console using the hack.

downgrading was a method that was used to guess a hash in order to patch an image that would boot 1888 wich you then could upgrade to 4532. this is not used anymore & not necessary anymore. divineo needs to update the product description.

all you need now is install this chip, get/ build the image, flash it and there you go.

the speed they are referring to is the serial output you can see on the screenshot. they can show the messages xell puts out (e.g. the fuses) in their "toolbox" software which is much better than writing the fuses off the screen or something.

if you boot a live distro on the xbox, you can ssh in and cut and paste they keys using your terminal, see this  example

Of course you can, but you must admit this not only makes it easier, but allows a very interesting feature that future homebrew could implement. I did alot of the early testing on the falcon and helped work out a few of these bugs, and not only do I highly recommend the product, but the team behind it is extremely dedicated to making a quality product with quality support.

buy a banned one cheap

Damn i really didn't think of that, were do i go about buying one of these banned boxes, do i look in the BST forum?

EDIT: i just looked on ebay and couldn't find anything

Do you need to build the parallel connector with the resistors to flash the right image onto the NAND?  And to take that further, wouldnt i still need to pull some info from my NAND (cpukey/etc) to populate any NAND or image i'd download from the net? And for that, is the only way using JTAG?

I'm trying to decide if i should buy this now or wait for another month or two to see if something better comes along.  My problem is that i do not have any old computers or laptops that support SPP parallel ports, so building the JTAG stuff is not much of an option for me unless i want to buy/build an old machine.

Thanks (IMG:style_emoticons/default/smile.gif)

[thethinker360]

hey nomorgow,

no parallel port for cygnos360 V2. it has a USB port! cant get much easier than that!

[jayboy86]

i wanna get one of these for my second xell 360, are there any uk sites selling it
thanks

[niai]

the uk cant sell mod chips its illegal

[jayboy86]

lol funny, i live in the country and i never knew that

will the links 2 provided in this topic send to the uk? anyone know
