After changing the region from my japanese Wii U to USA following this guide (https://lazr1026.github.io/regionchange/#/), it seems I messed up deleting the japanese duplicated titles and now I have only the following channels on my home menu:
WII U Chat
Daily Log
Mii Maker
Parental Control
Settings
It's missing disc channel, health and safety information, amiibo, vwii and others.
I have already downloaded the USA system update titles using JNUSTool and also MLCRestorerDownloader, installed one by one using UDPIH recovery menu option Install WUP, but no success. Health and Safety Information title ID 00050010-1004e100 installation fails showing the message "Failed to install: fffbffde"
Is there any other known way to reinstall firmware update 5.5.6U, restoring all stock channels?
the absence of health and safety information broke the autoboot tiramisu/aroma hack.
