Usually, this error code suggests that the serial number on your Wii U is modified. To resolve this, you'll need to apply the correct serial number to your console.
L+Down+Select
to enter the Aroma plugin menu. Then, go to FTPiiU and set Allow access to system files
to true
./storage_slc/sys/config/
and download sys-prod.xml
to your computer.sys-prod.xml
and ensure that the codes in the code_id
and serial_id
fields match the serial ID at the bottom of your console. If they don't match, replace them with the correct serial and save the file.sys-prod.xml
file to /storage_slc/system/config
, overwriting the previous file when you're asked to.Allow access to system files
to false
. Then, reboot your Wii U and Pretendo should start working once you log into your account.
