Can't press down home button

Ok so I am repairing an iphone 5c for a friend. She dropped it in the pool and after that it wouldn't turn on so she left it off for 2 weeks. I replaced the screen as the screen had cracked on it replaced the battery and charger port in it. I figured they were all cheap enough so why not. It still wouldn't turn on. I also noticed the home button after putting it on the new screen can't be pressed down. It's like it's something in the way keeping it from being pushed or like it's stuck down already. Would that keep the phone from cutting on after replacing all that? When I plug it into my pc I get nothing at all so what could be the problem?

What would the screws do? I've tried it with and without the screws in the logic board.

Re the stuck home button: loosen the two screws that hold the bracket to the back of the home button. By ¼ of a turn. Then test and adjust.

Re the water damaged phone: from experience, in most cases I don't spend time and money on phones that had liquid damage. I do it to try and recover data. But for saving the phone (the hardware), it is far from efficient. Water is invasive, it will go beneath all the chips and to all the solder joints and start corroding them. Specially pool water which could be saline or chlorinated.

Once the board dries, corrosion sets in and starts wrecking havoc on the board.

If the phone did work after it dried, it is likely to fail soon after. You start loosing functions like display, backlight, touch, service,Wi-Fi, sound, etc.

However, if you do wish to retain and fix a water damaged phone, the minimum is to take the board out, soak it in IPA at 99%, brush and air dry. This is far from ideal, since corrosion is still occurring under the shields.

A better solution is to remove the shields from the board, and do the IPA treatment.

The best solution is to remove the shields then clean the board in a pro sweep ultrasonic cleaner and then do the IPA treatment. Currently, this is the best solution we know to stop and remove corrosion even from under certain chips.

This however does not restore the missing solder and strength to the joints which will fail at the slightest stress.

We do fix water damaged phones sometimes for the sake of the device. When it looks like the damage is minimal and there is hope that the board's integrity is not highly compromised; and never offer warranty to the customer. Which sucks for them if they pay money and get an often soon to fail device.

The home button only went one one way I put it on the way it came off of the other screen because it has to be in a certain spot for the home button contact points.
