Newbie, need help on upgrade Z310i

[ho8882000]

Hi1 I am a newbie.

I would like to upgrade my Z310i's software to "R6BC002 070607" version.

I already downloaded the following 3 files:

1) XS++
2) Z310_R6BC002_FS_CENT_EUROPE_RED52.fbn
3) Z310_R6BC002_MAIN_GENERIC_AL_RED52.mbn

And i got the USB cable ready.

My problem is i don't know how to use them to upgrade my phone.

What other files do i need?

Also, do i need to finalize my phone, and how can i finalize my phone?

By the way, i am able to get my phone to communicate with "XS++".

Thanks!

Please help me!
