The only thing you could try would be replacing the battery and charge port. Do not wait too long as water damaged iPhones will start corroding and oxidising fairly quickly. If it does not boot with a new battery and charge port you will need to have your data recovered by a reputable repairer.

You have electrical damage on your backlight circuit from connecting the display whilst the battery was connected. You can confirm this by connecting it to 3uTools and see if it displays your screen or shine a torch on the screen when booting and see if you can make out the apple logo. If not it is an image problem and wouldn’t be worth repairing. There are about 9 components on the backlight circuit that could have been damaged but if you are lucky it could just be one of the filters.  You will not be able to repair this yourself unless you have the equipment and experience in microsoldering. The repair cost would be around $100 or more if the LCD connector needs replacing. It might be time for an upgrade.

Try this if you haven’t already. 1.       Press and release the volume up button. 2.       Press and release the volume down button. 3.       Press and hold the side button until the screen turns off and then turns back on. You can release the side button when the Apple logo appears.

You will need to make sure all the connectors are seated properly first. Than start ruling out parts like the battery and screen. After replacing the battery and or screen see if iTunes recognises it.

If you didn’t remove the actual home button I would make sure the connector is seated properly. If it is than you have most likely damaged the flex cable or nudged a tiny component around the connector. If it is a damaged flex you will need to replace the screen. The charge dock has nothing to do with the home button.

Most likely a damaged front camera flex assembly but I have seen a damaged home button flex show the same symptoms when both connected. You need to disconnect the home button flex and with the front camera flex connected see if it boots. If it still boot-loops with the home button flex disconnected it is defiantly a faulty front flex assembly and will need replacing. If it boots with the home button flex disconnected it is most likely a torn home button flex which will require another screen.

There is no easy solution for this. If you have ruled out parts it will be a faulty component on the logic board and you will need some experience and the right equipment to diagnose the fault. If you can, post the current draw on VDD_Main before prompt to boot. You can do this by connecting a squid or an iPower pro to a DCPS.

It will defiantly be a logic board problem since you have ruled out parts. If the customer is wanting there data it would be best to outsource it to a professional. If you are in the states I can recommend STS Telecom in Florida or IPad rehab in New York.

You should replace the battery to begin with. If it is still acting the same let us know.

I am not sure why touch isn’t working but if it is aftermarket housing I would replace all the parts from the old one to the one you are using, especially the dock connector.
