@ddouget1 the only way to get any files of the phone is by getting it started long enough to be recognized. You said you cleaned it but did not tell us how.

I suggest you treat it just like any other water damaged iPhone. The very first thing you want to do is to '''not''' try to restart, sync or otherwise try to use the phone. This may further damage your phone. The next thing to do is to clean it. Disassemble your phone using [[guide|30696|this guide] Then clean it with +90% isopropyl alcohol. Follow [guide|5825|this guide] , and even so it was written for a 3G all the points are still pertinent to your phone. You '''must''' remove all EMI shields of your board. If you do not, you are missing about 80% of the components to be cleaned. While you clean your board, check for any obvious damage, like burned or missing components etc. When it is properly cleaned, ''' replace the battery'''. All these steps are to avoid delayed failure caused by corrosion. I would also go ahead and change the [guide|29915|Lightning Connector Assembly]. then you will have a know -good starting point for any further troubleshooting, should it become necessary.  Once all this is done, reassemble your phone and reevaluate.

If you have no luck with that then you have to dig further into the actual electronics, I'd start with getting a schematic and boardview and test PP_BATT_VCC & PP_VCC_MAIN to see what the power situation is like and check for shortcircuits. If any of this is not within your capacbilities you do want to connect with users like @refectio on [https://www.ifixit.com/User/1395548/Minho|here] or @reecee on [https://www.ifixit.com/User/1358455/Reece|here] who have specialized in this type of repair.
