AP2.5 Game List

Rev 1.7; Last updated on 11:00PM EST, Dec 28, 2010

Currently with the LT+ firmware, there shouldn't be any freak out if the XBOX 360 fails an AP2.5 Challenge, as long as it has the LT+ firmware. If you only the the LT firmware and you attempted to play an AP2.5 game, you're definitely flagged and potentially banned. *Although Fable III seems to be having trouble playing on regular non-modified consoles, so if you attempted to play Fable III and got flagged, you may not be banned.

Confirmed Games
-Assassin's Creed Brotherhood
-Need for Speed: Hot Pursuit
-Fable III

Possible Games
-The Sims 3 (some regions may have it)

How to Check if You're Banned
If you got this error:

You're flagged, and instant-banned when you connect to LIVE

Otherwise,
To check if you're banned, use XVal.
*Some anti-virus software claims that XVal is a Trojan, this is a false positive. If you're scared to catch a virus, do not download.

Download "XVal_v2.0.zip", extract, and run.

Turn on your XBOX 360, go to My Xbox > System Settings > Console Settings > System Info.

Write down your serial number, and the xxxx-xxxx-xxxx-xxxx values.

Opening xVal, you will see three things:
Console serial #:
Encrypted X value:
Decrypted X value:

Put your serial number into the the first box, and then the xxxx-xxxx-xxxx-xxxx values in the Encrypted X values.

Click decrypt and hope it says secdata is clean.
Otherwise, it may say Failed AP25 challenge.

Removing the Flag
Huge thanks to Team Xecuter and M AzeeM K for creating this guide, posted below.

Using this tutorial will not work if:

1. Your console has already been banned
2. You have already been online with your flagged XBOX 360!

Purpose of this Tutorial
Suppose that because of a mistake e.g a failed AP2.5 challenge, your XBOX 360 gets flagged for a ban. This flag in its current state is an Offline flag and will cause a ban when you connect to LIVE. But, if you haven't connected to LIVE yet, then you have the ability to remove this flag so that you don't get banned when you log onto LIVE.

So, this tutorial tells you how to do this.

Now, first things first. You have to confirm whether your XBOX 360 has been flagged or not. Although you might already know it since you would have actually caused the flag, but its better to check it using another method by using XVal, posted above.

If you are sure that it has been flagged, then continue follow the tutorial:

Requirements

Hardware

- NAND-X from Team Xecuter

- Things required to apply the NAND-X to the Xbox360 motherboard:
i. A 15W to 40W Soldering Iron. 15W is recommended, although it is safe to use one up to 40W.

ii. Rosin Core/Flux Core Solder. Preferably 60/40 Rosin-Core Solder with 0.32" Diameter.

iii. Torx 8 and Torx 10 screwdrivers

- A PC with Windows installed and a working USB port

Software:

- JTAG Tool

- NandPro 2.0d

- FindSecData

- Windows PC with Command Prompt

*All of these programs are found below, on NAND Fixes. Download both of the NAND Files.part~.rar files.

Actual Work

Hardware

1. First you will have to open your XBOX 360 (and may also want to take the motherboard out of the metal case as it makes the soldering process easier).

2. Now follow the original NAND-X installation instructions present (please use google). You only have to follow the tutorial up to the end of the installation of the NAND part of the NAND-X and leave the JTAG part. Then continue on from the next step.

Software
Now, Remember that I am presuming that you know how to use Command Prompt, but I will still try to make it as clear as I can.

Remember, you don't have to follow this part of the tutorial per word (like naming the folders etc). I only wrote it like this so that everyone may be able to use this tutorial without any problem.

Also, before we continue on with this part, remember to un-hide the file extensions of different files on your PC so that there is no complication with name of the files including their extensions.

1. Connect your NAND-X to your PC. Once its recognized, move to the next step. Make sure your XBOX 360 is connected to the Power Supply but not turned on i.e. it should be on Standby. The PSU light should be orange.

2. Now, install JTAG Tool. Run it. Select the "Device Type" as "USB". Then select your Console type. Then press "Read NAND" and wait for JTAG Tool to dump your NAND. Its best to make at least three dumps of your NAND before messing with it. Name the dumps as nand1.bin, nand2.bin etc.

3. Now make a new folder on your E: drive and name it "Project Unflag" and copy NandPro(plus all the files included with it) and FindSecData into this folder. Also copy a NAND file from the ones you dumped earlier e.g. nand1.bin into this folder.

4a. For Windows XP users: Click Start--> Select Run--> Type in "CMD"--> Press Enter. You will then be opened a Command Prompt Window.

4b. For Windows 7/Vista users: Click Start-->Select All Programs-->Accessories--> Right-click Command Prompt--> Select Run as Administrator. You will then be opened a Command Prompt Window in Administrator Mode.

5a. Type "E:"
5b. Type "cd Project Unflag"

6. Now run your NAND image through FindSecData by using the following command:

findsecdata.exe nand1.bin

Now FindSecData will find out the block of the NAND which contains the Flag data and extract it, then fix it. You should see something like this appear in the Command Prompt window:

7. Now you will have some new files in the Project Unflag folder. All you have to do now is to type the exact commands in Command prompt as FindSecData tells you to write after performing its fixing operation. In this case, as shown above, the two commands will be:

All done. Now disconnect everything from the Xbox360. Also disconnect the Power Supply for about a minute, then connect it back and turn your Xbox360 back on. Check your XVal again and you should be unflagged now.

Reassemble your XBOX 360 and have fun.

Possible Prevention
GodzIvan, the creator of the NAND Write Protect, creates a diagram for grounding your NAND Write Port. Doing so will prevent you from writing any data to your NAND.

Ground this port, and your NAND will be unmodifiable.

Or follow this YouTube tutorial.

Advantages
-Brick-Proof against logging, perfect if you do not want to buy a Connectivity Kit for flashing your drives.
-No hard drive crippling on older Dashboards.
-Technically, if you were to be banned (and also have the write-protect on), your XBOX 360 doesn't know you are banned, so you could still have the ability to play movies and etc.
-Play unreleased games safely, although you should always verify on ABGX.

Disadvantages
-Microsoft could ban you if you connected to LIVE (as they could detect that the software could not write to NAND).
-Need to disable whenever you're updating, otherwise, your XBOX 360 will spit out a error.
