Why won't my Galaxy S2 turn on? SOMEONE HELP ME!!!!!

[AC Question]

So I have a T-Mobile Samsung Galaxy S2 and it had battery problems at first. Not soon after that it wouldn't turn on at all so they recommended to buy another battery and a battery charger because my battery charging port was damaged. That worked fine for about a year but now it won't turn on at all! I have some really precious photos and memories on that phone and it won't turn on. I went to T-Mobile and they attempted to transfer the pictures and contacts to my new phone but they couldn't with the battery port damaged. They told me to charge my battery and try turning it on again and that didn't work. I also tried to leave it alone for a couple days to try again and it still won't turn on! This really frustrating me so can somebody please help me. If you have any ideas i'll try it because i'm not giving up on it.
