Welcome to Cygnos360 – xbox 360 NAND flash – JTAG HACK – xbox 360 HOMEBREW -

“Certain” images floating around the internet make it necessary to patch the KV and SMC in order to run on Cygnos360 V2. This toolbox adds all the required functions to easily accomplish this task. The “Program Flash” dialog now allows you to specify a patched SMC and KV to inject into the image on the fly. A patched SMC can be created with the “Patch SMC” dialog, if the SMC from your original image is known to the toolbox. If this is not the case, there are pre-patched SMCs available “at the usual places”.

Another dialog “Extract KV” has been added, which will simply dump the KV from your original image (Remember to use the “Patch SMC” and “Extract KV” dialogs only with original images, they won’t work otherwise).

Please note, that this is beta software! It should only be tested by experienced users.

Have fun with this new toolbox and please report any bugs!

Some news from TeamCygnos

First of all, happy new year to everyone and welcome to 2010. Looks like it’s going to be a good year for Xbox 360 enthusiasts with all those neat applications coming in on almost a daily basis now.
We have not held a winter sleep either and continued to further improve the Cygnos360 V2. We have made major improvements to our Cygnos360 v2 Firmware which is now in 1.03 final.  (you can get it here http://www.cygnos360.com/Downloads/Cygnos360%20V2%20Firmware%201.03.zip
We have significantly increased the flashing speed for 16Mb xbox 360 NANDs.
With the new firmware v1.03, programming takes 24 seconds and reading 28 seconds. That is a full image, not a partial!

The new toolbox is also available which fixes small problems and makes flashing even more reliable.

In addition to that, we have been able to get rid of the necessity to solder resistors or diodes to perform the JTAG hack which further simplifies installation, leaves less room to make mistakes and increases success rates of launching the exploit.
Instead of the resistors or diodes, we are directly talking to the jtag port with appropriate voltages rather than with an approximate value.
The installation manual has been updated to give you a better understanding about installing a Cygnos360 v2.
Cygnos360 V2 for 16Mb NAND 360s is available in many countries around the world now with more shops and install-services coming in.
(see http://www.cygnos360.com/resellers/ for the list.

Many people are asking each day about “big block support”, meaning the Jasper versions with 256 and 512 Mb NAND flashes. We have this already running on prototypes in our lab and we are finalizing tests. We hope to release this before mid February. This will not be a firmware update but rather another hardware revision. Preliminary tests on the prototypes give us less than 10 minutes on dumping a full 512 Mb image and about 5 minutes for the 256Mb version. Programming, which is then a 64Mb partial flash takes merely 2 to 3 minutes.
We will also introduce partial flashing possibility by then so that you can do certain “fixes” as well now using the Cygnos Toolbox.
We are trying to push this revision out as soon as we can, but at the same time we will make sure it’s the quality you expect from us.
Please have some more patience, it will be rewarded!
In addition to the above news, we have changed the look and features of our website www.cygnos360.com which will allow us to give you a better service with more frequent news and updates. Also, we now have an official German support forum at Modcontrol (http://www.modcontrol.com/Board/forum177/)
So, happy modding to everybody!
best regards

*DISCUSSION ABOUT THIS RELEASE: HERE *

Hello,

a new firmware v1.03 beta 2 and toolbox v1.08 is available for download from here:

• Cygnos360 V2 Firmware 1.03 beta 2.zip

• Cygnos360 V2 Toolbox 1.08 beta.zip

*** BETA firmware and toolboxes should only be tested by advanced users. ***

The firmware contains all the new features of the previous firmware 1.03 beta. Please refer to this thread for further details. In conjunction with toolbox v1.08 beta, the new firmware will greatly improve upon read and write performance.

On our test system, programming a 16MB flash took 48 seconds with firmware 1.02. With the same firmware, reading took 55 seconds. Cygnos360 V2 was plugged in a cheap USB 2.0 hub for these test. With the new firmware v1.03 beta 2, programming takes 24 seconds and reading 28 seconds.

Performance has been much worse in the past when Cygnos360 V2 was connected to a USB root hub. This situation has improved now up to a point, where it is only slightly slower.

Your feedback is always welcome. Since we altered the timing of the NAND-flash reading and writing, regressions in this area may be possible. If you experience reading or writing errors you did not have previously, please report!

Differences in read and write performance are also of interest. Enjoy!

Cheers,
TRaceBack

Here it comes. updated version of the manual with lots of input that came from the forum. thanks to all people who contribute with good feedback!

enjoy. feedback welcome!

xZool has uploaded a video of the new hack booting off a Cygnos360 V2.0

We managed to patch XBMC for linux so that it runs on the xbox360. It is still a prove of concept and does not have sound or video acceleration, but it runs!

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- und 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

Stay tuned, more information will be coming soon!
