See "Romeo Alpha Delta" for more detail. This trophy isn't too difficult once you get the hang of the game. This must be done in one attempt as it's not cumulative.
You will have to fly for 5 kms in one game. This means just in one run. Try to use as many vehicles as you can, buy some revives from the store and try your best not to die. To help make things easier, also buy some gadgets and utilities:
Dezapinator- for 6,500 coins it can randomly disables nearby zappers
Missile Jammer for 5,000 makes random missiles detonate by itself, rendering them harmless
Ezy-Dodge Missiles- for 5,500 makes missiles move slower, therefore making it easier to dodge and avoid them
(you can only apply 2 at a time, so take your pick)
And utilities (I would encourage not to use this as they cost a lot and are for one use only):
Super Head Start starts you off at the 1500 mark. Buy 1 for 3000 or a pack of 5 for 10,000 coins
Quick Revive revives you when you die. Buy 1 for 10000 or 3 for 25,000 coins.
Let's say you want to resign The Last of Us, but you can't. When you load up the save, a written red text incorporated in the box, which says something along the lines of, "must be updated to games.conf before you continue". Here's what I did.
1- Click ABOUT and then select UPDATE (PS3 RESIGNER AND GAMES.CONF). You will then be taken to a website, never mind that. A box should have popped up with multiple documents. In which, there should be one called "Games". Open it with Notepad.
2- Now minimize that box, for now, and go to this link (which was provided upwards from here): You must login or register to view this content.
3- Find the game you need. To make it easier hold "Ctrl + F" and type in the title of the game. You will then be taken to it, if it is there. If so, copy the information which should look something like this:
4- Pull up the notepad again and paste the information you copied in alphabetical order. So, for instance, Jetpack Joyride would be among the games that begin with "J" and then it would be placed in alpha-order within the set of "J-games"/. Though, I think you know how to put something in alphabetical order, huh?
5- Finally, if you haven't already, close the program (PS3 Save Resigner 2.0) and go back into it. Now, try to resign the save again. If the red text doesn't reappear in the box, then you're good to go!
Put it in the games.conf / Save Resigner or BruteForce
