Is there a way to get my E75's firmware back to RM-412? I used NSU and it updated it to the latest RM-413 version. I then realised that there are more region options for the RM-412. Tried changing the product code to one of the RM-412 ones but NSU keeps saying there's no update for me.
Any ideas? Cos I really want to have simplified chinese support on my phone. Tried the Hong Kong one for the RM-413 but for some reason, the web/browser doesn't work (just flashes and disappears) and some of the keys on the qwerty keyboard are swapped around.
Thanks in advance.
