I have a hacked switch. Version 7.0.1 last time I checked. It started having issues where if it jerked around too much, the SD card would stop being read and the whole thing shut down. I swapped the SD card reader with my working switch. Same issue and the "broken" one worked fine on the new one. I'm scared it might be a motherboard component but would like someone knowledgeable in these things to give me a little help.
