i accidentally installed a stub version of IOS249 on my Wii, and now the wii is freaking, usbloader gx doesn't work anymore, and i can't install/uninstall anything anymore, because they all require IOS249 to work. i tried it with anytitledeleter, but it asks me to pick the IOS to use, and then I pick IOS249, and the Wii just blocks. i tried it with IOS 55, but it doesn't work, errors all the time. can i use another ios so ATD will work? What now? also, if i restore my nand via a bootmii backup, will my game progress be lost? like i made a backup last week, if i restore it now, will all my game progress be lost of this week?
