What You Will Need:
1. Data Migration Kit (or XSATA/ X-Port/ Transfer Kit).
2. Xplorer360
3. Xbox 360 Profile Editor 2.5 (WORKS WITH ALL DASHBOARD UPDATES)
4. NET Framework 3.5 SP1 (If you don't already have it)

How To Do It:

Step 1: Connect your HDD to your computer using your Data Migration Kit.

Step 2: Open up "Xplorer360".

Step 3: Click "Drive > Open > Harddrive or Memory Card".

Step 4: Navigate to "Partition 3> Content> [Your Gamertag ID]> FFFE07D1.

Step 5: Right click on your profile and click "Extract". Yours probably won't be as big as mine (56MB), but they always start with an "E". If you are having trouble finding your profile, delete old profiles from your 360 that you don't use.



Step 6: Save your profile to your desktop or anywhere you'd like. Leave "Xplorer360" open.

Step 7: Open up "Xbox 360 Profile Editor".

Step 8: Click "File> Open" and select your profile that you just saved



Step 9: Now you should see a screen like this after it loads your profile:



Step 10: Now using the scroll bar on the left side, select a game that you want all 1000 Gamerscore in. I'll be using "Blue Dragon", because it doesn't have any online achievements, therefore decreasing my risk of being banned.

Step 11:Click the "Online" or "Offline" box, and then click "Set" to unlock achievements individually. Click "Unlock All" to unlock all the achievements for that game. Note that for online achievements, you can select the time it was unlocked. This can be used to make it look more legit.



*Do this with all the other games you want. I'm warning you again, don't get too excited and overdo it. Before you continue, remember that you could possibly get banned.*

Step 12: After you've unlocked all the games you want, click "File > Save".

Step 13: Now go back to Xplorer360. You should still have the window open, like I said earlier.

Step 14: Now click "Edit > Insert File". Select your profile that you just edited. Click "Yes" when it asks if you want to overwrite.

You're done! Now plug your HDD back into your 360 and see if it worked.
