Hello. A friend brought me his o3ds which he said had arm9 installed. He says he tried to update luma (I am guessing to ver 8.0) without updating to boot9. After that all he gets is a black screen. I have tried holding start, select, l, r buttons while booting with his SD in and nothing. I have also tried with an old sd card I have with and older luma. All I get is black screen, does not turn off or anything. He does not have a nand backup on his SD, and does not know on what version firmware the 3ds was on. I was going to try and hard mod it and patch the nand with boot9, but I would need to know the version the console was on. Any ideas of what I can do? Edit: I have asked him and he says all he did was change files on SD card to try to update luma. He never run any updater, and the 3ds ever since has not booted. Wierd since it should boot without the SD card in (or at least blink on then off if luma was not installed in ctrnand).
