Hello everyone, I recently got a EOS 70D and have been using it around for 3 months and I love it! However since a month ago everytime I try to capture a photo it says error 02 as seen in the photo. I tried removing the card, cleaning it and reinstalling, formatted the card and changed battery and nothing worked. I use a 128GB Kingston memory card which I know it can handle, and the person who had it before me also used the same brand and amount and it worked fine. I have yet to find a solution, anyone know what might be wrong? Thanks!
