[AC Question]

I was trying to replace my usb charging port flex cable, and there was another one attached to it towards the bottom, it has a little strip that attaches further into the phone under the plastic. I accidentally ripped it off thinking it was on there so someone could tell if you messed with it (like a warranty sticker). Can anyone help me identify it? There's a magnetic gold strip that connects the two cables. Also, am I screwed for pulling it off? It's a cheap phone and I don't want to spend a lot to fix it.

Hi, how did you get on with the above, did you manage to fix the phone?
