Good evening!
What a great profile pic,
@Aurora Wright. Madoka Magica was and is amazing <3!
Well, now on-topic, I had a problem (which may be a Luma bug, but I'm not sure, to be honest).
After following 3ds.guide and setup everything correctly (and everything was working perfectly) with FBI, HBL, Luma Updater... installed, I "updated" Luma with Luma updater and that seemed to cause a problem with my FBI which didn't allow me to install any cias, so I decided to delete everything but arm9loaderhax.bin, copy that file to another folder outside the SD, format the SD and after that, put the A9LH.bin back in in the root. The config worked perfectly and I managed to get to the home menu. Everything working flawless. After that, I made a "payloads" folder with GodMode9.bin inside it in "sd:/luma" and made files9 folder in the "sd:/" (root) of my SD with the corresponding "aeskeydb" from the 3ds.guide and then with the SD in my 3DS, I powered on my 3DS and pressed [Start] before the 3DS turns on, I selected "GodMode9" and an error showed up saying:
An exception occurred
Processor: ARM9
Exception type: undefined instruction
[...] a lot of Hex values [...]
Press any button to turn off the 3DS.
Well. It will probably be my fault because I missed something or a file, but I didn't manage to know what thing could it be.
So, summarizing:
> Followed 3DS.guide. Everything worked perfectly.
> Installed the FBI, HBL... CIAS. "Updated" Luma with Luma Updater. I messed it up. FBI wasn't working anymore.
> Copied A9HL.bin to another folder and format SD.
> Tried to put everything needed back in.
> GodMode9 error after selecting "GodMode9" in Luma chainloader.
Thank you very much. Have a nice day!
