Is it possible to downgrade my emuNAND with sysUpdater? On sysUpdater's github pages it says "IMPORTANT: Don't run this with any sort of firmware spoofing enabled like Gateway mode/rx mode/whatever or it will brick!" Does it mean it would brick my sysnand if I tried this? I want to revert my emunand to version to 4.1 or 4.2, on a separate sd card, just for using an old DS Flash Card (r4igold revision C "doraemon", which was permanently blocked a long time ago). If I can't do this, which is the correct way (if there is one)? ps.: Already tried that unblocker CIA, didn't work for my flashcart. ps2.: I don't have a 4.1 or 4.2 nand backup. ps3.: I'm using rxTools. ps4.: I don't have enough money to buy one.
