HAS ANYONE MANAGED TO CHANGE THE PRODUCT CODE ON THE 5800. I AM DESPERATE TO UPDATE THE FIRMWARE BUT NO UPDATE AVAILABLE FOR MY PRODUCT CODE 0575384 PURCHASED FROM SPAIN IN DECEMBER.

Tried NSS and PHoenix to no avail to change product code.:redface:

Would anyone know of any software that could do this?

HI

Same here, wanted to update mine by NSS but no luck but did it today with help from two web sites.

And it actually worked and I now have V11 and loving it!!:)

I cant post web links so send me an email and i will let you have them.

I update my 5800 phone to v11 via Phoenix an after update product code also was changed. So for next versions I will use FOTA or NSU.
