    Hello everybody,
    First of all sory for my bad english, but i realy need your help and I cant find my awnsers on the internet.
    I recently opened my iphone 4s to replace the battery for the first time. I followed some videos online and everything was going well.
    I closed everything up again, but when i pressed the on button, nothing happened. So i put it on my wall charger (not itunes - mac) and it went on and the battery showed 100%. My wifi and GSM weren't working and when i took out the cable my iphone died, it wasn't starting.
    I found out that you needed to plug your iphone in your computer to make wifi and GSM work again, but once i put it in my computer the iphone starts. Black screen, starts, black screen, starts etc.
    I found on an older post that you needed to switch your iphone to DFU mode, let it charge for 30 minutes and then start it, but that didn't work for me as well.
    I might have done something wrong inside my iphone, but one of my bottem screw got striped, so i cant seem to get it open by myself. If you guys think it is an internal problem, i might bring it to a shop, so they can repair it. But if some of you have a solution how to fix this, i would love to hear it!

    Lots of thanks for the person that could help me!

    Did you use an original or third party battery?

    If WiFi is greyed out, it's a MLB problem, so it looks like you've broken the MLB.
