edit: A9LH uninstalled and I'll be sending it in to Nintendo for repairs. 90% sure its a hardware problem, someone in the IRC suggested maybe with the camera? Either way at this point it seems there's nothing I can do. I'm unable to boot my N3DS, here's all the relevant info I have - Pastebin of error (from Luma's ErrDisp) Bought it on Black Friday (its used N3DS XL, not the special Mario edition N3DS) and I've been using it fine ever since. As soon as I bought it, it was the target system in a DSiWare downgrade and last Saturday it was used as the source system to downgrade another and has been formatted since. Upon booting "An error has occured. Hold down the POWER button to turn off the power, then turn it on and try again." - Google couldn't help me out. That error is called the 'black screen of death' for the O3DS and it was commonly caused by the wireless chip being loose. All the errors upon booting for the N3DS I have found just resulted in a black screen. Luma config works fine. I cannot boot with or without my SD card. I've restored previous NAND backups, still nothing. I can boot in to safety/recovery mode and check the internet for system updates. After it tells me there are no updates, it turns off and I'm back where I started. Here's what some nice folks in the 3dshacks IRC have helped me find so far. My error looks like it's coming from a titleID called QTM Services : http://pastebin.com/AiXPJah1 https://www.3dbrew.org/wiki/QTM_Services Using GodMode9 I can't find the titleID anywhere. That's as far as I have gotten. At this point, I think its a hardware issue. Coming here as a last hope before returning it/sending it in for repairs. Edit: Bit of more information regarding the error I found this morning from https://www.3dbrew.org/wiki/Error_codes Desc : 1022 : Timeout Summary : 11 : Internal Module : 96 : QTM Level : -1 : ??? No negative values on the 3dbrew page.
