So, as I've spent a few hours guessing out how the puzzle of type-code-firmware goes, I'll post it here hoping it will help someone:
For every model, there are three variables into consideration.
First is the Product type, in the form RM-xxx. This refers to the hardware specifications of the device, and obviously can't be changed. Different product types mean some major or minor difference in the hardware.
Then is the Product code, in the form of seven alphanumeric digits. Each code corresponds, and is followed by, the product type to which it applies (RM-xxx), plus "VAR" (meaning variant), plus a series of shortened words giving information about what can we expect to find in the firmware: the geographical region and/or country for which it's meant, that will get the OTA (over the air) updates; the brand (service provider) shipped in the firmware (or the letters CV if it's unbranded); the handset colour (only for the default tones we'll find when first powering it up); and some other variable information, like the size of memory, etc. So, it can look like this:
code-------type-----variant---region--provider ------ country memory colour
059T1B8 RM-892 VAR --- EURO SWISSCOM CH ------ 16GB --- GREY
Some of the shorts are easy to guess, some others I have no clue.
Thirdly we have the firmware version, aka ROM or Windows Phone version, which is what we all want to get updated. The version consists of sixteen numbers in groups of four separated by dots. Every Product code ships this or that firmware revision, getting OTA updates every now and then. Different regions, countries or providers get higher updates than others. People in Norway get a different OTA update than those in Hong Kong, and branded phones usually are updated earlier than unbranded ones.
Now, each physical device has a "hardcoded" Product code (that we can find in underneath the SIM-holder). In the example above, it would be a phone bought in Switzerland, sold by Swisscom carrier (and very likely SIM-locked), with 16GB store space, grey colour, and capable of working on certain frequencies. So, now, what can we flash it with? Well, we can flash any Product code as far as it's the same Product type as our phone, without losing any capability. Note: flashing a different Product code will NOT change our phone's original code. And when we switch on the phone, we'll get what we flashed: a default language or set of languages, perhaps a service provider logo, a default colour for the tiles and apps, and of course the features that Bill Gates' staff fancied and condescended to include in the corresponding firmware update. So, if we want the latest version, probably we'll have to flash a Product code not corresponding to our country or region, though I assume that all of them have, at least, English built in. It might also happen (this is my guess) that certain firmwares don't include a setting for LTE, if there is no LTE in the country for which it's meant, even though the device is LTE-capable.
Now, is it possible to flash a Product code corresponding to a different Product type? Yes, but we may lose some capabilities. For example, the Microsoft Lumia 925 is RM-893 in North America and RM-892 in Eurasia. They're capable of different frequencies for the 3G and 4G bands. So, cross-flashing will make us lose all the frequencies not matching both Product types: some because of the hardware, some because of the software. Not much to lose if, in exchange, we're getting a newer Windows Phone version; because, sorry to say, WP really sucks, and the sooner we get the updates, the better. After all, who can yet enjoy LTE? I bet that 97% of the Lumia owners can't.
So far all what I've found about this topic. Enjoy and, if you find I wrote something wrong, please let me know.
Enough good writing/abstract
Finding Product Code and Firmware
What if my product code is not listed anywhere and I want to flash the firmware? Anyway to find it?
Also, NSU's Data Package Manager gives firmware details according to product code, how can I get firmware of different product code to suite my device? Sorry for being noob here.

I received my device as a gift without any boxing or wrapping. Also, it's firmware is pre-release. What I can see only is it's type, which is RM-877 and it is a AT&T variant.
NSU, needs product code to get new associated firmware. And I can't find it anywhere. So, is there any tool/key combination which can detect and tell me the product code?
And what if the product code I find, is not listed?
Thanks for the help.

Thanks a lot.
Sorry, but this is getting exciting for me and just want to confirm before going ahead.
Yes, my device is Nokia Lumia 1020 Black with RM-877_nam_usa_005.
However, current firmware is 3042.0000.1321.10102 (I believe it is pre-release)
So I hope flashing this device with RM-877 VAR NAM US ATT SL BLACK wont brick my device. I heard that AT&T 1020 devices are bit tricky to flash.

I had some issues but was able to flash without further problems... My lumia never got the updates OTA but thanks to YOU I have them now via Nokia Care Suite. Everything working perfectly! Thanks a 1000 times...
Question about LTA and SWAP
I'll looking at this firmware:

Any idea what LTA and SWAP mean? Is this an unbranded firmware I can use in the US (on ATT/Cricket)?
Thanks for any insight.

Thanks! I also had a question about another product code:
059T104 RM-915 VAR US ATT IDB PIB SL
Not sure what the IDB and PIB stand for.
I understand that 059T105 RM-915 VAR US ATT PAYG SL would be the GoPhone version and 059S925 RM-915 VAR US ATT SL would be a postpaid one i'm assuming, but can't imagine what difference the 3rd would be. Thanks again!

Lumia 520 : RM-914_apac_taiwan_473
Hi, I'm not sure to be on the correct thread. I apologize in advance. I've bought the phone recently. I'm planning to use it in Argentina. I'm waiting for the windows 8.1 update which is being delivering on these days. It doesn't arrive to my phone. I've been trying to find out if my CORE BUILD ID: 3056.40000.1349.10387 is included on this update. I can't find any information on it. I've found information about some other similar CORE BUILD ID: 3056.40000.1349.xxxx, but nothing about mine, which finish on 10387. I don't know what these numbers means. I'd appreciate any information and advice. What should I do to get the update (flash another rom, change product code, whatever)
Sorry for my bad English

Hi,
Do not look at the "core build", because no use. You must look at the firmware version in settings hub > about.

Many thanks, I've found it.
It is : 3056.40000.1349.10387.2001 and is "under testing".
As I wrote on my last post, this phone is to be used in Argentina. It's a present. I wonder what should I do? Do I flash the phone with Latin America firmware (having present that these firmwares are RM-915 and mine is 914)? Should I keep the original of the device? Other possibility could be flash it with Spain firmware which is 914, update is already available. Maybe I'd better wait the original firmware, right?

AR CV is RM-915, so this means that you can most certainly not use AR CV (since almost certain impossibility to flash RM-914 > RM-915).
You can use ES CV (Spain) if you want yes: 059S5D4 RM-914 VAR ES CV
Hello guys. I am searching the internet from past two days but cannot find Product codes for the following Product types for the region Finland (FI) and Argentina (AR):
1) RM-914 (Unbranded)
2) RM-998 (Unbranded)
Please anyone provide me with all the product codes available for these two devices in the specified regions. It's a humble request.
The reason for this is that I wanted to flash the corresponding firmwares on the devices (Network Unlocked) to receive the Lumia Cyan Update ASAP.

Ok, I have found.
However, I advise you to flash the 059W4X2 RM-975 VAR NAM 4R CV ROM that integrates the variants of CA CV (000-CA) and USA CV (000-US). If you want to flash the 4R CV ROM, so download this file FFU (01061.00070.14246.29001 FW version).
But if you still want to flash the 059V6W5 RM-975 VAR NAM US T-MOBILE SL WHITE ROM that integrates the variant of T-Mobile USA (TMO-US), so download this file FFU (01061.00070.14253.28018 FW version).
