So last night i was playing pokemon ultra sun. I went to mystery gifts and was checking for gifts from via internet. The game froze and gave me an error which i was forced to turn off my system. When i turned back my 3ds the theme turned back to basic white. I went to PKSM (newest update) and clicked on ultra sun to check for wondercards however when it said "loading graphics" it gave me another error and it turned off automatically. At this time my DS couldn't turn on. The power LED just turns blue for like 5 seconds and turns off. I tried everything and even tried getting all my files from my SD card on my laptop, however my laptop won't even read the SD card at all anymore. I tried many different programs to check if it reads it but it doesnt even show up at all! However it does make the popout noise when i connect the sd card but it will not show up at all. I have many saves and games on this ds. I am running the lastest firmware on my 3ds. Please someone help !
