will not turn on

Hello,

Please supply us with some photos of the two cracked things.

I'm going to assume the round things are the areas where the screws go into. While most of these being cracked or broken will not have an effect on the phone, some of these cracks may have spread to traces on the board.

Possible solutions:

1) Simply reassemble the phone, being careful not to over tighten the screws in these locations, in risk of increasing the cracks. You will know very quickly once the phone is up and running if anything is acting weirdly. If so, these cracks likely damages electrical traces on the board.

2) If acting weirdly, look at the cracks under a magnifying glass and try to see if these cracks lead through any traces. If they do, you can try repairing the traces on your own (some guides are on here), or bring it to a reputable shop that can attempt it for you.

Without knowing exactly what spots, this is my best guess on how to assist you.

Hope it helps,
