That means essentially I cannot root, cannot TWRP and pretty much anything else.
First thing first, I would like to remove all the Japanese bloatwares in the phone. Found a link from here with scripts to do this without root. Still have not done this yet. Planning to do more reading before diving in.
Second, is there anyway to root the phone without unlocking the bootloader? Some says no and some says yes (but didn't provide the link).
Appreciate any help from kind community members here.
Hmm..can I even flash to global firmware? It seems without unlocking bootloader, I cannot even do that.
