Here is the thing. A friend of mine bought a 3ds on 1.1.0-0U (I was there when he bought it secondhand). He bought it with a flashcard, which the previous owner (non-tech father of a kid) said that he took it to a store to be updated and it stopped working recently. Then his 3ds would read my original 3DS carts. But refuse to read his flashcard. After i hacked it (CTRNand a9lh Luma) it still refused to see the DS cartridge. It's not the flashcard, as it works on all of my three 3DS on the same setup. I also tested my flashcards on his console to no avail. But KH3D and Resident Evil:Revelations stilk get picked up with no problem. Using forwarders is useless as well. It only whitescreens as if no cartridge was on the slot. Thing is, if TWL Nand was somehow bricked. This would have happened on an unhacked 1.1.0-0U 3ds with only flashcard access. (Can you even damage the TWLNAND this way?) Once i hacked it i updated it to 11.2 with no problem. Extended memory games like smash/super mario maker work as well, so that's not the issue. I'm completely clueless as to how i can solve this issue and this is why i kindly ask for your help fellow tempers. Thank you so much in advance.
