hello,
I'm trying to use a dfplayer mini but it won't work! i've done everything! used sdcardformatter, reformatted EVERYTHING! does anyone know how to fix this? If so please reply 
do you think you gave us enough information? my crystal ball is broken...
oh yeah forgot :). sorry about that! please tell me if this is enough!

Your SD needs to be less than 32GB
what's your Arduino ? how did you wire and power the DFPlayer?
how is the Arduino powered ? I don't see ground connected.
have you tried without the resistor ?
what do you see in the Serial console
You might want to try also with this library:
oh yeah I did connect ground I just looked for the same schematic lol. No I have not tried without the resistor. I see "Unable to begin". i'll try without the resistor and i'll report back here.
a picture of a hand drawn schematic as things are (and how it's powered) would go a long way compared to the theoretical ugly fritzing ....
From your Fritzy thing the problem is clear. There's no power going to the DFMini. Or to anything else. No power, no working.

oh yeah I did connect ground and vcc I just looked for the same schematic lol
So when you say "the same schematic" you mean a useless picture which is NOT a schematic of your system. So you still haven't posted a schematic or even said what you connected "ground and vcc" to. Good luck - I'm out.
