The main ribbon that is inserted into the motherboard came off. Can you help me with this? Below I have tried to explain it best I could. I had no problem with taking everything apart following your directions and it was when I was doing the assembly and went to attach the ribbon the part attached to the motherboard that the ribbon slipped into came off the motherboard. It almost seemed powdery and crumbled off. I'm no tech but was wondering if this is something I can fix or do I need professional help. Thanks and I really like your tutorials they are very helpful.

*This is the ribbon I'm referring to from the dismantling controller directions Step 6 but I was reassembling at this point. "There is a latch you flip up on the circuit board (blue arrow). This is easy to take apart but a pain to put back together. Make sure you have needle-nose pliers or tweezers for this when you put it back together." Oculus Quest 2 Controller Disassembly
