won't power back on after opening
So I opened my iphone 5 because when I would put it on speaker the microphone didn't pick up my voice so I looked on he bottom and a lot of he holes were dirty si I opened it to clean them out.
-I turned off he phone with 20% battery left
-I opened the iPhone removing the two screws.
-removed the home button ribon and removed the speaker I've done it before in a 5c and on this 5 there was a small plastic piece that tucked under the mother board that has a sponge on top it was rather hard o remove. (the screen is still attached)
-I messed with the mic on the ribon taking the black silicone cover somewhat off.
-put the mic back then the speaker
-tried to turn on the phone and black screen.
-tried disconnecting the battery and putting it back on, removed the screen and put it back on and nothing not even when I connect it with the charger?
What did I do or what can I do to fix. Thanks in advance.
Is this a good question?

You probably knocked off / damaged the small components near the battery connector. Someone else here will have more knowledge on what's going on here.
