Place your phone in a ziploc bag with silicon packets(packets found in beef jerky bags) in it and leave for a few days if you dont have any you can buy a bag on amazon for cheap for a couple hundred. If after a few days still doesnt work take the phone apart and check for any rust or deposits. If you are not technically able then take it to a phone repair shop they should be able to clean the phone up and fix it for you. Sometimes it may be a shorted battery that needs replacement so I would check the voltage on your battery also. Good luck
It may be possible that you shorted out the screen while connecting. Try restarting the device and charging it. If it still does not turn on make sure the device is turned off and see if there is any loose connections somewhere or the connector is not seated properly. Hope your problem gets solved and you dont need to replace again
I have seen this before could be some pressure on the lcd so try to see if you have any dents on it somewhere and see if touching it in certain places makes it worse or better. If not then the lcd is damaged and would eventually need replacement.
I suggest using packaging tape over the broken glass and a ifixit iopener and heating the glass in sections. A heat gun should work also but make sure to not overheat the phone. When you have heated up one section use a guitar pick or something slim to shimmy underneath the glass and split apart the glue. If you have a very thin metal tool such as a curved screen metal open that is millimeters thin I would use that but only along the edges and with caution. Do not try to force your way through the glue as you might cut the wireless charging oil and damage it. So work in sections heating up the back glass and slowly pushing through the glue until you. Half of the phone done. When moving in to the middle of the phone toward the center be careful of how much you heat it up and force the glue. Once you get past the wireless charging coil you should be fine. Another piece of advice is make sure you got the tiny piece for the camera lens to replace if you didnt take that off. I suggest getting a new one because...
To get the plastic broken piece out of the one blade you must take it apart. So similar to replacing the servo motor you have to pull the bottom piece of the oneblade off. Then remove the power button casing but be careful because the plastic at the top attaches to the body where the razor gets put in, so the casing is where the power button sits. Once you take that off you will see lube to the servo. You will see where the blade connects into the plastic housing. If you have a toothpick or something small you can try to push it through the plastic at the bottom as it is very thin and push the broken plastic piece out. May take a few tries but it will work. I did mine in 10 minutes so it's not too bad Thank you for reading hope this helped.
