I bought a WZR-HP-G450H in Japan and the GUI is in Japanese. I would like to have it in English.
I can't find an option to change the language so I'm guessing the only way is to install the US firmware?
I tried installing the US firmware using the GUI firmware update tool but it didn't work - the GUI is still in Japanese. I've read this is probably because the Japanese models don't recognize the US firmware's security signature and so will not install it.
Would someone have any pointers or step-by-step instructions on how to change the firmware on a Japanese model to the US firmware. Or generic instructions on how to bypass this security signature step to force a firmware update?
Thanks!
