[Q] Can I update an unlocked Lumia 520 with the ATT 520 ROM

I bought this Nokia Lumia 520 phone, unbranded and unlocked. It came with a Latin America stock Nokia Lumia 520 image.
This is the update that should go with the phone since it matches the product code.
059S5V2 RM-915 VAR LATAM-LTA LTA AV
But I would like to use one of these below.
059T105 RM-915 VAR US ATT PAYG SL
059T104 RM-915 VAR US ATT IDB PIB SL
059S925 RM-915 VAR US ATT SL
With the exception of the top I have no idea what those letters mean. I'm with AT&T right now.
What's the difference between pay as you go image and the other two?
Is it possible for me to put one of these ATT images on this phone?

Are you sure that it's unlocked? Because at today unlocked tool no exist :what:

It's an unbranded phone with no sim or carrier lock. It came with the latin america build. I was just trying to figure out how to put the US software on it instead of the latin american one.

Explanation of Microsoft Lumia product type, code and firmware.

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.

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 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)

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

[Q] Microsoft Store Unlocked 1020 (RM-877) ROM Product Code

Anyone know the ROM product code from the unlocked Lumia 1020 (RM-877) being sold at the Microsoft Store in the U.S. and Canada? Looking to download the ROM but need the product code. BTW, I'm flashing a Canadian 1020, but the Americans out there might want to try this on an AT&T 1020.
Thanks in advance!

Unbranded ROM
Actually what i am trying to do is replace a branded canadian rom with a unbranded one, the problem is finding the product code on the one sold at the microsoft store so i can download it. The problem is not technical, i am just looking for the 7 character code. why i mentioned AT&T is because it may work to replace the AT&T rom, someone may want to give it a try.

There are currently no unbranded ROM for USA or Canada.
"sold at the microsoft store" = I guess they sell with unbranded ROM (for compatible country).
- Either you take the AT&T ROM.
- Either you take a unbranded ROM of country other than those mentioned above.
059V0R9 RM-877 LTA VAR AR CV SKD is the only unbranded ROM for RM-877, it is Argentina.

Microsoft store links to unlocked 1020
The phones in question are:
For canada - microsoftstore.com/store/msca/en_CA/pdp/Unlocked-Nokia-Lumia-1020/productID.305260100
For US - microsoftstore.com/store/msusa/en_US/pdp/Unlocked-Nokia-Lumia-1020/productID.304844200
on the US page they say "This unlocked phone can be used with either AT&T or T-Mobile. It is not compatible with Verizon or Sprint. SIM card not included." as the AT&T version has AWS disabled, i am assuming it has a different ROM to allow full use on T-Mobile. Also, they only started selling these versions a few weeks ago, so i figure the product code is new, which is why it is not in the links in anaheiim's lumia unbranding thread. (The unbranding thread is very good BTW, thanks anaheiim!)

As I've said here, there is no unbranded ROM for the American or Canadian NL1020.
However, you can try:
- Either you take the AT&T ROM.
- Either you take a unbranded ROM of country other than those mentioned above.

Hello there, hopefully one of you guys with more experience can help me out here.

Then it appears to starts updating and I get this:

sorry for being (a little?) off-topic, but i've not found a better place to ask: is there a way to unlock this phone from Orange Romania? Product code is 059x0g9. I've followed the tutorial, and i've flashed the firmware recommended above, but when inserting a SIM card from Telecom (a T-Mobile subsidiary), it complains that the phone is locked into other operator's network.
Would i have a better chance by flashing a Vodafone Romania firmware and using one of those cards? Or is this phone doomed to be part of Orange network forever?
Regards,
Cornel
