The new way to play non J tag
What you will need.
1. A USB STICK.
2. Horizon 360 mod tool. (search and download use your web browser)
Put your usb stick in your 360 then go to settings and choose storage, Then, configure your usb stick to be used as xbox hard drive space.
Then copy the profile you want to use on to the usb stick from your xbox hard drive.
Now sign out and create a new profile (it does not have to be online just create a new one)
Now copy the new profile you made on to the usb stick as well then remove the usb stick from your xbox and put it in your pc.
Start horizon on your pc when it has loaded it should automatically detect your usb xbox hard drive that you made on the xbox. Click the profile tab and you should see the two profiles you put on there.
Now double click the profile that has the games you want to start it should pop up in a new window and you should see a tab called content click this tab.
now you should see all the files in the profile right click on the file called account and extract it to your desktop. Then back out of that profile and open the new profile you made.
Do the same click content and find the account file then right click on it and choose replace. Find the account file on your desktop and double click it to replace with the one from the profile you need to start games.
Now this step is important after you have replaced the account file get rid of the window showing you the files but don't back out of the window with the profile info (the one with the content tab) look at the top of the window and click SAVE AND REHASH! now you can back out of horizon and safely remove your usb stick.
Right put the usb stick back in your xbox 360 and sign in to the new modded profile you made and it should ask if you want to save your password on this console tick the yes box or whatever box you need to tick so that you don't need to be asked for a password every time you sign in with this profile.
Then your xbox might ask you to update the trems and conditions so if asked do it then it should think for a bit and then sign in you have done it pat your self on the back and start the game that belongs to that profile just to test it. It should start just fine woop woop!!
To play on your profile you will need two controllers you signed in on pad 1 and the modded profile signed in on pad two. now start the game on your profile and hey presto you can play non jtag again thanks MOZZY .
And because the new modded profile you make is linked to your xbox because you made it on there you won't get signed out. Everybodys will be different because we all have to make our own modded profile for it to work.
The bonus of this is DLC and ARCADE should work again because you can stay signed in AWESOME!!!
Now with every bit of good news comes some bad news so here go's this method only works so far with profiles that you don't need a password for you know the ones that still sign in but won't go online. So far i have found three profiles this works for thay are as follows.
STEPELLOW profile
SIR HOUND profile
WRCbyGG profile
Thay all work perfect on my xbox after you do this method
To get all the other profiles to work again it is up to the uploader who uploaded it to sign in on the xbox it was made on tick the do not require password on this console box. Then use horizon to extract the account file and upload it so we can use this method to get it working again.
Then instead of asking for a password it should just do this. It worked for me with my mozzy616 profile it was asking for a password on my friends console but after i did this it just asked to tick the box when it signed in problem solved.
I HOPE THIS HELPS THE NON JTAG COMMUNITY.
