I just opened my Phone to change the Apple logo into a glowing one (some of u might know) now, after I did this i wanted to start my phone but nothing happens. The Screen doesnt start and yeah. I thought that maybe I have to charge it but this reuslted in an overheating! After this I reopned the Phone unplugged the Batterie and plugged it in again. Now its no more overheating but still doesnt start. for the describtion. I unplugged battery and the 4 Cabels for touchscreen lcd and stuff. And i removed the little tape from the cable which gives the screen enough electricity to do what it does. https://www.youtube.com/watch?v=D0BrG7O8… <- thats actually what I did. Pls can sonmeone tell me what could gone wrong?? thx for ur help

My friend you have to undo what u did first (change the Apple logo into a glowing one) change it back to what it was and see the result out.. I am pretty sure that the flex cable attached to the screen connector for power source is kind of sorting out.. properly align it and see… better still remove it and power the power the phone to see if it worked out?
