I do realize it's hard to find a Comet, but other cars are fine too.Your current IP address has been blocked due to bad behavior, which generally means one of the following: Here is a video (credit goes to YouTube user "kooki3m0n5t3r") showing that it most definitely is possible to do get this achievement using the FIA method. It depends a lot more on how you hit the jump than how fast your car is. I personally got the achievement using the smaller taxi.

Another suggestion I have is to not bother to take too much time looking for specific cars to attempt it with. If you keep hitting the ramps correctly, you'll eventually get it. What I personally suggest, is to use the yellow ramps at the Francis International Airport, which is the more used and more hated method. That definitely isn't the case, when I went for the achievement, I remember I had 2 or 3 rolls on the ground and it popped. I also don't agree with Quiksilver723, who says in his solution that you have to get 5 rolls in the air and rolls on the ground don't count. I did 10+ rolls when I was trying this a couple months ago and still nothing popped. The holding the RT to link the rolls didn't work for me either. It might be possible to get the achievement using the swingset glitch, but getting the glitch to work all depends on luck and even then, it might shoot your car completely straight and it might not flip at all. The method that Cenrail suggested does not work for me either. I don't know why there has been a large amount of positive feedback for the most part, but it seems that using cheats (for me anyways) blocks any and every achievement. The method that Markyshizzle suggested in his solution did not work for me. I noticed that there were a ton of solutions for this achievement, but here are the methods which I've tried that DID NOT work for me. Remove the update, start up your game again and don't download the update ( don't worry, you will be able to download it anytime when you log back in to xbox live), now proceed as usual.

If this happens to you then you should go to your dashboard and clear your cache, using your system blade on your dashboard. Although this is not confirmed and people have been able to obtain this achievement, using this method just fine after the updates have been downloaded it is worth mentioning that there is also a number of people that ran into some trouble. It should be noted that one of the game updates is rumoured to cause some issues with the linking method. It will accumulate the rolls you made in the seperate jumps and you will get the Achievement. If you start making flips do not release the right trigger, hope that you will land or flip back on your wheels and repeat this process about 2 to 3 times. The game registers your roll as a row as long as you hold the right trigger (accelerate). I want to add one other detail that may save you a lot of time and effort.
