If you bricked your phone that means something went wrong and you can no longer start it anymore.
A phone can be soft-bricked (e.g. you are stuck on the blue screen but can still get to #dic:recoverymode ) or hard bricked.

Here is Fairphone’s Guide to get out of the “frozen state” (bluescreen, soft-brick). If this doesn’t help, try to install Fairphone OS again.
Here is XDA’s Guide wich also has a possible solution for a hard-brick. (Needs Windows)
