So I just picked up a Wii U which is still on firmware 1.0.2! (I almost accidentally updated it during setup by entering my internet settings, but when I realised it was on 1.0.2 I quickly deleted them) Is it worth keeping this Wii U on 1.0.2, or should I update it? If I should update which firmware should I go to? (I read a while ago that 5.1.0 has an easier IOSU hack?) Also would a NAND dump from this console be useful? Or do devs already have everything of interest from the early production firmwares? Thanks in advance for any advice!
