Oh, that was my bad. I added the firmware and other files to the SD card and the menu appeared without pressing R, although im really not sure what to do from here. Once i select "Boot Firmware", it appears 2 warnings that failed to load/patch TWL/AGB, even tho i downloaded and added them to the SD card and if i chainload the luma A9HL, it flashes a white screen for half a second and goes back to corbenik menu again. I made sure i disabled all the patches and tried it multiple times with different options selected from what i read on the github.
Any advice on the next step?
Edit: I was using the wrong A9HL on the chainload, switched to the Luma3DS one, and the Luma3DS config opened up for the first time (since i deleted the luma3ds folder), but still no progress, black screens, blue LED on.
