i don't know, a full power down does not remove the DS exploit now,so not sure about how it can be removed or if can be removed or if there even needs to be anything installed like the previous exploit at all ,my guess is that we will just put some files on the SD card , maybe something on the MSD and then scan a QR code through mii maker to initially install the exploit , then after that to launch it we will just go to mii maker and hold a button or button combo while launching into mii maker to trigger the exploit and get GW rom menu
right now running DS mode is the only way to get rid of the exploit entry , so maybe launching MII maker normally without holding the button combo will break the new exploit
