It was a number of things,
I saw the wifi couldn't connect to the network so i made a new connection then i tryed to install the latest Wii software from the wii setting because of the popup that was saying that there is a new version but it gave me error code 32007.
Then i downloaded a game from the Shop Channel (migoto fishing or something that i use to have) then i went to the HBC Backup and asked me to update the HBC from 1.09 to 1.12 if i remember correctly i tryed twice but didn't seem to be able to updated.
Then i went to USB-LoaderCFG and downloaded some missing covers and a theme there. Finally i went to BootMii and i did a NAND backup without waiting to get verification and a restore after that.
At the beginning i couldn't even get to the HBC (it was also giving me a black screen) but the i re-installed it and it starting working again.
Thanks you
