Here is the deal: I have an old 3ds xl with the latest update (11.3 36 U) I have never done any 3ds hacks before, this is my first attempt. I followed this guide: 3ds.guide Which directed me to this soundhax guide: https://3ds.guide/homebrew-launcher-(soundhax) And I followed it with no problems and everything was ok The only minor differences were: 1- In Section VIII - CTRNAND Luma3DS (Here) the guide said I will need to unlock SysNAND (lvl1), but the 3ds did not prompt that massage to unlock it and copied the file without any problems (I did have to unlock it in other parts of the guide however) 2- In Section IX - NAND Backup, a massage showed telling me that there was not enough space in my SD so I skipped the backup for now until I get a bigger sd. After finishing the guide, the first thing I did was opening the luma updater thing, and it gave me two options, regular update (or something like that) and an hourly update. I chose the hourly update, and then it downloaded it and showed a success message then tried to reboot I guess. And the 3ds turned off and since then I can't turn it on! It just stays black and the blue light turn on for a second then turn off. I tried holding START and tried with SELECT as well with no luck. The contents of my SD are as shown in the attached picture. I also have only one folder inside luma\ called luma\payloads and only one file inside it GodMode9.firm (Which I used a lot as shown in the guide) I should also mention that the 3ds won't turn on with or without the SD, so i'm not really sure if it has anything to do with it.
