Someone please help me be able to transfer files to my phone from my PC! topic

It used to work, doesn't anymore.

USB debugging is enabled. Camera is connected as a media device. Using the original OEM cable. Drivers are updated....

so wtf? It just says "copying" when I try it on my PC, and on my laptop it immediately says "transfer stopped, device not connected or not responding"

I really need some help on this one, if anyone is up to it, thanks in advance!
