rm-877_nam_usa_005
Hello, Claro Dominican Republic gave me a new Lumia 1020 as a replacement for a defective one, the new one is rm-877_nam_usa_005 and it is on Amber, it says it is there is no available update for firmware. The older one was updated wit Claro regular Cyan firmware and 8.1. Does somebody knows if I can change the firmware or what I have to do to get Cyan? thank you.

lta roms?
can I flash my rm-892 lumia 925 with rm-893 lta brasil rom? or should I just stick with rm-892s? i am going to use the phone in turkey, so i probably need my phone to be suited for local gsm radios, or it doesn't differ that much?

Hi,
If you will use your Lumia 925 RM-892 in Turkey, why do you want to flash an RM-893 ROM?
In addition, the BR CV (000-BR, RM-892_lta_brazil_277) ROM is an RM-892 ROM, not an RM-893 ROM.
RM-892 is the RoW (Rest of World, international) hardware variant of Lumia 925. I advise you to stay on an ROM RM-892. In addition, the TR CV ROM (000-TR, RM-892_eu_turkey_361) is an RM-892 ROM.

7So, 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.2
Changing this file will not help. MD5 signature of two files are identical, as you can see (click on image to enlarge):I have purchased a Nokia Lumia 625 in India "059T1M1 RM-941 VAR IMEA IN CV" I don't get the highest connection speed as 4G when I travel to UK or Malaysia and use a 4G enabled SIM. Can I cross flash it "059T454 RM-941 VAR EURO GB CV" and will this enable 4G option
or can I just replace this file "NWP8 simlock 3gstandard bb5 crcA59A.bin" from the Euro ROM to the Indian ROM and flash to the get the 4G option enabled?
059S3W7 RM-914 VAR IMEA-MEA3 AE BH KW OM QA+ AV has already obtained GDR3/Lumia Black (3056.40000.1349.2001). You are sure that these updates are not proposed to you?1
Your 1020 is black color?
I find this AT&T Product Code 059S9T1 RM-877 VAR NAM US ATT SL BLACK (if your 1020 is black color).1
Hi,
Do not look at the "core build", because no use. You must look at the firmware version in settings hub > about.1
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
