This thread is to answer questions about XBL and Jtags, as well as reduce the amount of spam threads about it. So, let's begin.
Firstly, can Jtag's, Devkits, and RGH's connect to XBL?
-Yes, however, proper modifications done via software are needed. The methods used by individuals who are online have not been released, so don't tire yourself out looking. Trying to connect with an out of the box jtag will result in a failed attempt to connect and a ban (I think, correct me if I am wrong).
What stops me from going online?
-There is a small encrypted file located on the console Nand, known as the Hypervisor. The hypervisor runs a series of tests on the console while it is connecting to Xbox Live, and builds a "response." The response is basically your console in a nutshell, the response is sent to an Xbox Live server, and checked for flaws. If your response matches, you get online, if your response does not match, the above mentioned outcome will occur.
Here is a little addition by Dwack:
You make it sound like the HV itself is responsible for the checks. It's more like the bouncer for the 360 night club, controls what goes on and who gets in.
If you want the plain jane HV you can extract it from the NAND. It is the first 0x40000 bytes of the kernel. Just remember that it will have to be decrypted and patched up to the newest build.
Getting the HV that has all the keys and other information is somewhat more involved. Not to say it is hard, but with a few patches using XeBuild you can grab it using a modified systemcall(just one of many possible ways to get it).
When you connect to XBL you are sent a payload(signed and encrypted) from MS. That payload gets sent to the HV and uses high level privileges to check the system. It checks certain register values as well as performing a SHA hash of the HV at predetermined offsets/lengths.
Since XeBuild hacks up the HV so much it is obviously going to fail.
How do I find the Hypervisor?
-Finding the console Hypervisor doesn't really pose a unique challenge (It is the first 0x40000 bytes of the kernel. Just remember that it will have to be decrypted and patched up to the newest build. Creds to Dwack), however finding it is only half of the battle. Dwack has left some relatively helpful hints scattered throughout several different modding forums that may shed some more light upon the subject. Anyways the Hypervisor is encrypted and any attempt to modify the scripts can cause some pretty messed up errors, including a console that refuses to boot. So, the answer is dumping the Hypervisor while it is un-encrypted and at it's most vulnerable (I hope you can figure that one out for yourselves) and then gaining the ability to edit it in such a way that when the response is built it sends a response identical to that of a retail. No spoofing, your console must actually PASS the checks.
What is the Atlas Project?
How does the Atlas Project Work?
-It's really quite simple. When you gain authorization to use Atlas you get an xex file, and when you try to connect to XBL your console is instead first directed to their server. If your console has in fact been authorized the server will send you properly modified files and allow you to connect to Xbox Live. However, if your console is not authorized, your attempt to connect to Xbox Live will time out, and stop you from connecting, in an attempt to save your KV.
What is The Sable Project?
-The Sable Project was revealed to be a revision of The Atlas Project, boasting lower prices and a functioning user interface. The project, however, was put on hold for an undetermined amount of time. (Not trying to start a flame war, just stating facts) There UI was actually just a modified sample found in the SDK.

The developers of the application are not currently online and will not comment on the progress of their development to anyone other than their trusted and loyal followers. Of which I am not:

But? I saw files about a socket server that could get me online?!
-No. Although most people you know online are probably using a server, one is not needed to get online. The servers are used merely as a method to control the number of users online and monitor them carefully. Getting a Jtag online can be accomplished with an Xbox, a Computer, and some wicked coding skills.
I will be updating this thread as much as possible (maybe some pictures to make things look a bit nicer). There is a possibility I got some info wrong (I'm very tired) feel free to let me know and I will correct any mistakes. I will also ask some 1337 H4x0rz if they have anything they would like to add. Please, no stupid "This Might Work 2 Get Mah JTAG Online" Posts Here. If you have a question you would like to ask go ahead, I will do my best to answer. As for those of you who may have a better understanding of how this all works, please go easy on the "n00bs" it might seem obvious to you but they may see things totally differently. Let's keep a calm friendly discussion going on here.
As for admins, I have seen things like this closed or moved to premium before. There is absolutely nothing in this thread that would warrant that. Most everything in here is common knowledge, and there are no files being shared, only knowledge.
Thanks For Reading!

Thank you for the post, but I just had to add this little comment in.
Just because you made this post to prevent these questions, (which I do feel is helpful enough for a sticky), doesn't mean some n00b isn't going to sign up for an account today and post another "OMG GUIZZEE, I NE3D ONL1NE FilEZZZ!!" No matter how much everyone wishes they wouldn't :/
Just saying

Too much reading, not enough info on getting my jtag online :trollin:
I wish the submit button took you to another page that says you can't get a jtag online, then when you pick ok, it's just a endless loop, of you can't get your jtag online pages.
