Navifirm Plus which I downloaded, you have a choice of 3 indexes you can use,
1. Nokia Care Suite (so same server the nokia suite uses, except you can then flash it to any compatible phone)
2. Quality Assurance (I am taking a guess, this server is where Nokia release firmware versions to be tested by the cellphone networks like MTN, Vodacom ect who then approve the firmware to be released to their phones)
3. Production External (no clue)
I grabbed mine from the 1st server, and it is the same version that was officially released.
Now if you use the Phoenix software, great thing about it, it can even flash phones that you bricked with a bad update, no idea how that works, but I assume it talks directly to the hardware.
So step1:
Go into Phoenix, figure out your product code (its actually different number in NaviFirm that what you get from *#0000#)
step2:
Go into Navifirm, -> Nokia Care Suite Server
Choose Nokia N8 (RM-596)
Then next column choose software version, for Belle it is 111.30.609
Then in Variants column choose what you need, mine was "euro3_dg (0599766)
Then on the files side, click "Mark All" but then untick the 1.22gb emmc file, which is just gonna format your internal memory drive and wipe your photos ect. and its 1.2gb you dont have to download.
Step3:
Close phoenix
Place the files into the the product folder. Eg. on my pc it was:
C:\Program Files (x86)\Nokia\Phoenix\Products
Inside that folder create a folder called RM-596
Then place the downloaded file into this RM-596 folder.
step4:
open up phoenix
Detect your phone
Make sure phone is fully charged just in case you brick it
Flash firmware
Software will tell you what to do, even if something goes wrong.
ps. A tip. When you installed Phoenix, make sure you dont run a antivirus/firewall ect which can stuff up the installed, because it is cracked software.
Navifirm that I used:

Basically everything on my phone works, with the exception it was missing my South African MAPs ect which I just downloaded again.
