I was reading up on the new dash, security checks, and AP25 and my mind started to wonder about something.

I have a few consoles like so many of us do and 2 outta 3 are modded with LT 1.1. My roommate has one that was banned last year in the 2009 wave and this got me wondering.

If I have a modded console dedicated to offline play with an offline HDD and an offline profile that is NOT banned/flagged and I make a boo boo, such as playing a game that is the most unsafe, dirty, STD of a game ever, and xVal 2.0 reports to me that me that my SecData has been compromised, can I not revert back to a clean SecData PRIOR to going on XBL. Almost as if I never committed the infraction that caused the SecData to show that it's bad and not 'clean' (I dont know what it says if its not clean; just assuming).

People have been reverting their NAND dumps to uncripple the HDD but I have only found instances where they were already hit with the hammer and they wanted the functionality back. I have no reason to believe M$ knows when and how many times I play a game offline. Maybe except if an achievement has a time-stamp on it which would be a dead giveaway if the achievement was recorded to the profile at a specific time and the NAND data says something older).

So would it actually work to 'clean up' my SecData by reviewing/changeing my SecData back to a previous time if for whatever reason I decide to go online? How would they know if I changed the values in the NAND?

Best way to do what you are talking about is this.

Lets say you have a brand new xbox in your hands right now.

1) update dash, you might only want it updated to 9199 at this point to avoid ap2.5
2) dump nand
3) hack your dvd firmware, play anytihng on it you want, even ban magnet games offline.

LT+ comes out

4) restore nand from your backup, you might want to restore the dvd firmware too
5) update dash to newest version
6) backup nand again (previous backup is useless after you update)

repeat steps 4-6 everytime a new dash comes out and you will always have a clean nand to revert back to. Still this wont help unban you but it would make uncrippling very easy and it gives you a perfect way to clean all possible traces of what you have been playing on it.

I like what your thinking and your on the same page clearly but one thing. What I wanna know is if my console is NOT banned and I decide to go online one day can I simply check my SECDATA with xVal 2.0 before i go online (because there should be no reason why the server side should know anything if im OFFLINE) and if the console is flagged/not 'clean' can I simply revert it to a previous date? The way i see it is I would not have to worry about anything. If I get flagged offline and the NAND stores it, can I just restore like it never happened and assume that the xbox wont report anything suspicious?

[syntaxerror329]

Yes, if you check the secdata you very well could detect that you have been detected and then restore the nand and you would be good as new again. I have not used xVal myself but it sounds like what you are suggesting will work. It is just going to be alot of effort on your part.

I do not know much about how the banning/flagging works and just thought of this while reading about the new security measures. It would be awesome if someone could confirm if they were in fact able to clean theri SecData before going on line a few times. I dont want to ruin my consoles  (IMG:style_emoticons/default/sad.gif)  and im sure most everyone else doesnt want to either.

Edit: Also to answer anyones question the general consensus is that offline achievements DO NOT record a time stamp and it makes sense now that I think about it because my xbox360's clock says 2006 or something so there is no way they would stamp a date that was 4-5 years incorrect. Here's a link to a quick question and answer but if you dont believe me just google.

It might be possible to prevent a ban by grounding the write protect leg of the nand. I havn't tried it myself as I don't drive mod, but it should work in theory.

So this would disable the xbox360's ability to write to the NAND chip then? I have to look into this NAND stuff more. Ive never done it. I have just read about it a little.

I have the same problem you've mentioned.  My console is offline and flagged with "Failed AP25 challenge".    It was never connected to the internet in its life, so I know there is nothing flagged server side.  I want to know how I could revert the Nand to previous state.  I have never made a nand backup before, but I have read somewhere that there are always two instances of the nand stored, one is a previous backup copy, while the other is the current nand in use.  I obviously already have the new kinect dash installed.  

I found this tut here: http://forums.xbox-scene.com/index.php?showtopic=697231 about reading/flashing the NAND.  Will this tut still work for the new kinect dash?  Since it's only a flag that I am trying to revert, I assume I don't need CPU key, DVD keys, or any of the more advanced JTAG stuff.  Hopefully someone fluent in xbox NANDs can shed some like for us here.  TIA

if you get the AP2.5 flag you can restore the nand and make it clean again, as long as:

1. You backed it up before you were flagged and xval says your secdata is clean.
2. Your backup is the same dashboard version of your current dashboard version. (IE: If you are updated to the kinect dash, you can't use a 9199 backup of the nand to clean your data.


If you already have a AP2.5 failed flag in your nand, it may still be possible to clean the secdata by following this tutorial:

Make sure your secdata is clean by using xval before going online or you will be flagged by xboxlive and never be able to go on live again.

Thanks madboxer, this is exactly what I wanted to know.  I never backed up my nand prior, so I am thinking using the tutorial link you posted.  Here is another question:

If I attempted to boot an AP2.5 game twice, does that write to my secdata twice?  So would I need to zero fill the two latest secdata timestamp regions in hex?  Or does it only flag once, even after repeated attempts of loading an AP2.5 game?  Is the secdata the same as the xval?  Thanks.

If unflagging your box is very important to you, I recommend stop using the box until you attempt that tutorial. Although your secdata is flagged, the xbox keeps old copies of the secdata in the nand. I have not done enough testing to figure out when the box backs up the secdata.  To be on the safe side, I would attempt a recovery ASAP. The more you use your box, the more likely secdata is backed up, and if all exsiting backups are AP2.5 flagged, then you are SOL.
