Thanks for your reply. Sorry it has taken so long to try this solution.
I downloaded the files and have them on an SD card, but I do not have the copy or paste functions on my unit? See attached picture.
Hi All,
I've messed up! I used DZO's mrz99 usb file to try and change from Japanese to English, on my mrz90 and didn't back up as everyone seems to have updated without a problem.
Now my screen is messed up.
Can any body help please!!!!
