I have four DF players which I need to play audio, and the fist two worked pretty well, I removed the SD card from the first one and put it on the third and the fourth to see if it was a card issue, it didn´t work and made worse the problem because when I put the card back in the first DFPlayer that was working already, it didn´t lighted nor sounded, but the other SD card is working on every single DFPlayer, it´s very rare because that card is locked (I can´t write files on it) and it happened after I put it in one of the first two DFPlayers and it´s the only of my six cards that work, I think that maybe in some way DFPayer locked the card, It seems like a very basic thing but it is getting my nerves and I´m so worried because I need this proyect to be done before thursday, I´ll appreciate any help
