Hello everyone! Now system update 5.5.2 has came to wiiu, I tryed using dns block but didn't work, then I installed firmware spoof data but had an error, so I used ftpiiu_everywhere to delete a folder where download system update is, and it works. Here's the tutorial. Although it might be not possible to cause a brick, I'm not response to any brick, follow this tutorial at your own risk! First, you need mocha, HBL and ftpiiu_everywhere on your sd card, open HBL by using Haxchi or Internet Browser exploit. Second, please open mocha cfw,then you will go to wiiu menu, and reenter HBL, open ftpiiu_everywhere, use a ftp cilent to find your wiiu, and open NAND/storage_mlc/sys/ folder, delete the "update" folder, then press HOME button and go back to wiiu menu and go to system setting, touch "system update" option to start an update, if an error code (in my case 105-3012) appears, this means wiiu can download update data, but can't save it. And wiiu can't re-create that folder itself. If you want to update,please create update folder in storage_mlc/sys/. If you want to open eshop, nnupatcher is ok. I use JPN wiiu. I'm a Chinese and my English is poor. If you find somewhere you can not understand or mistakes, feel free to correct me. -------- The above is anew translate are better than me(thanks a 91wii.com number).
