I have a Switch that has been running SX OS for a little over a year now. It is on FW 9.0.1 and it started freezing on me a few days ago while playing Luigi's Mansion 3 so I restarted it and put it on the dock. Yesterday when I picked it up, I could not get the screen to come on even though it would show that the payload was successfully loaded in TegraRCMgui. Long story short, after troubleshooting it all day yesterday I discovered it was an issue with the SD card. When the SD card is inserted, the screen will stay black. If I remove the SD card and try to boot something like hekate, it boots hekate up just fine. Again, it wont boot hekate though if the SD card is installed. The SD card I have been using for the past year or so was formatted to exFat. So, I formatted a new SD card to Fat32 and put fresh files on it but the same thing happens. The screen will just not turn on with a SD card inserted. I was going to try restoring my Nand but as far as I know it has to be on an SD card to do that, so I can't do that. Anyone have any suggestions?
