I accidently teared the power button cable a little.

I guess i will have to buy a new one, but i wonder is it soldered ?

I don't think so but i'm not sure.

Is there a nother way to power it on for now ?

I completed the steps as described and have an issue with my display now. I tried to start the device before pressing it in the back cover to check whether it works or not. It seems to work, but the display don't. Which cable is that of the display and / or what could have gone wrong? Thx!
