You still have to use NNU Patcher to access eshop by running it and smash bros update still needs to be installed via the wup installer cause remember your not actually officially on FW5.5.0 just a con Firmware to make Ninti think you are fully but you still need wup to install game updates. Should do the trick though
Edit: to put tubehax in if your already connected to the internet the only thing you need to change different is Auto obtain dns and add> 107.211.140.065 to both settings which you already did have since changing from opendns which I did the same, just different addresses.
