What is the Lumia 530 UK CV product code?

[anon(9000941)]

Hello,

I will be getting a Lumia 530 in a couple of days (its bundled with a tablet I'm buying; my 1520 is my main device). The thing is its from Tesco Mobile and I'd rather reflash it to the unlocked, country firmware as soon as it arrives.
I did this when I got my 1520. Bought SIM free, it had the HK firmware so I quickly flashed GB.
Now, although I remember the procedure, I can't for the life of me work out what the 530's product code should be.
I think the description should be RM-1017 VAR EURO GB CV, maybe with black on the end. How does this translate to the product code?
To clarify, I want to flash the UK (GB) CV (unlocked) firmware edition onto an RM-1017 Lumia 530.

Thanks,
Ilmiont

OK after a lot of digging myself - this code isn't easily obtainable online it seems -, 059W310 seems to be the CV GBIE one I want. Hope this helps for anyone else
