Wii U with NNID 5.5.5J

[DaroNoname]

hello, I recently bought a Japanese model of Wii U on ebay, there are NNID accounts on the console that require passwords, I can't do anything, is there any way to remove it? I tried to upload aroma but after restarting the console it requires a password to log in again, I wanted to connect with filezilla and it doesn't work either

You can press + upon boot to create a new local user. Has Parental control enabled also? then either brute force it or

If your console has firmware of 5.5.x you can try :
UDPIH: USB Host Stack exploit + Recovery Menu

There you can remove the Parental control password then reboot and create a new local user.You need a Raspberry pico or anthing with RP2040 chip. Or just buy the pico anyway since high change you cannot see the version in your current state.
