How to get my portable charger working? Answered

Im building a portable USB charger but for some reason my phone ins't showing any sign of the charger being connected. It used to show when it was connected but I cant figure why it isn't now. I measured the voltage going to the USB its 5v and the two data lines are 3v. I used 33k and 22k for the data lines so i can get 2v to each line. Is there anyway someone could kinda assist me on making this circuit on a breadboard i'm kinda getting confused on how to set it up. Also is my 7805 going bad because sometimes the input voltage is the output voltage.

Ok a different approach. Do you have your voltage reg wired correctly, cuz if you don't it will do what you are describing.

What is the voltage dividers for? So the fone will recognize to take a charge?
What are the pin numbers for the LM7805 you actually have in your connection?
Pin 1 is?
Pin 2 is?
Pin 3 is?
