As the title says, the achieve "choose a side" wont unlock. I've won a game as a decepticon and autobot and even have the achievement where you have to win as every character. Help pleasee?

Use the search function. There are a handful of threads that already discuss this and what some people did to solve it.

I think what the rude guy here meant to say was that this cheevo has a stipulation on it:

You turn Restrict Factions to No, then choose an Autobot on the Decepticon's Side, and vice versa. Will unlock offline.
