I have T-mobile Nokia Lumia 521(RM-917) and I want to use W-CDMA 900/2100MHz.
Lumia 520(RM-914) supports it, so I tried flashing GLOBAL SWAP rom (059S0P5) with Nokia Care Suite, but I got this error:
0x00030007: The boot loaders in FFU file are not signed for this device. RKH of device: 9DF6E11153C33AA85F7984C21EFA43AEDF9B82BE52199E83AE53AA7625019F65. RKH of FFU image: F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD

Is it possible to flash Lumia 520 rom to Lumia 521?
Short answer: No.
Long answer: No, you can't replace the physical radios present in a given model of phone by reflashing the firmware; where'd you get an idea like that?
Be glad those signature checks are present; people who've managed to override them in the past have managed to brick their phones, or at least leave them in a crippled state.

I got this idea from AT&T Lumia 920 on AWS 3G (1700/2100) IS POSSIBLE

Ok, so im new to Windows Phone and after lots of reading I still have a few small questions if anyone wouldn't care to humor a noob. So here is my situation...
I bought a lightly used, sim unlocked, RM-940 ATT branded Lumia 1520 with the intention of flashing the latest stock firmware in order to start with a clean slate and get rid of ATT's bloat as well as be able to take developer preview updates from microsoft. I use an ATT MVNO so I need to make sure it's sim remains unlocked. From what I understand the newest RM-940 ATT firmware will relock the sim to ATT, which is exactly what I don't want. So from what im reading my best option is to flash the RM-937 Global Rom. I remember there being a Dev ROM for the Lumia 920 but I havn't seen any mention of such a thing for the L1520. Am I correct in assuming that I can go backwards from RM-940 to RM-937, or is that not possible? Would anyone care to set me straight please? I would greatly appreciate it.
I'm also interested in this info. Did you find if it's actually possible to flash a Lumia 1520 RM-940 (AT&T) with a Lumia 1520 RM-937 (Global) firmware?
Thanks.
It shouldn't be able to. AT&T and global f/w support different radios, and afaik, AT&T models always use different radios than global models. Fancy USA.
I have Lumia 630 (RM-976) and it doesnt support 4G. If I flash Lumia 635 (RM-974) rom to my phone what would happen? Has anyone tried something like this? Can I get 4G support?
You won't be able to, either the FFU signature checks or the platform ID check will fail.

Even I change model info using registry? I saw a topic about unbranding at&t lumia 635 devices with flashing rm-974 rom to rm-975.

FFU flashing doesn't use the registry, it uses the platform ID which is related to files in the PLAT partition. (contains ACPI tables and other configs)
FYI, a friend of mine ****ed about with PLAT partition and hard bricked his lumia. So it would be a good idea if you did not mess about with PLAT partition at all.
Hello,
I unbranded my Lumia 640 using this guide http://forum.xda-developers.com/windows-phone-8/general/brand-att-lumia-640-lte-t3294971 and am wondering if it was possible to "re-brand" the device. When trying to flash the FFU of the AT&T ROM, the Platform ID doesn't have the _ATT at the end so it won't flash. Can I "re-brand" the device or is it stuck like this?
Thank you.
Ok, I have in my possession a Lumia 640LTE from MetroPCS and I would like to get it Window Mobile 10. I've already unlocked it from MetroPCS (got the unlock code and put in a non-MetroPCS SIM and entered the code).
I've been going through the forums and I can't quite determine the best method to go about this? That is also the easiest, sure fire way (no bricking). The only thing I have done so far is use WPInternals to unlock the boot loader, and I've tried to put "RM1073_02166.00000.15084.41001_RETAIL_prod_signed_1005_01DE1D_000-CA.ffu" on, but it fails via WPInternals.
I'm sorry if this is such a Newbie question in advance. Just please point me to the proper thread. Thanks in advance!!!

Unfortunately, it says there are "no updates for this device". Which is the same thing when I try the upgrade advisor. This has been an issue with this phone since it was from Metro PCS, as they never allowed WM10 for the Lumia 640 LTE
Flash a diferent variant then.

Could you recommend a different variant? I'm not sure which ones were allowed to be upgraded to WM10 in English besides the "Retail" version (I think).
The phone is the following from (w w w.lumiafirmware.com/ser/RM-1073/guid/059X0M9):
Phone model: Lumia 640 LTE
PackageTitle: RM-1073 VAR NAM US METROPCS SL
Product Code: 059X0Q4
manufacturerHardwareModel: RM-1073
I used RM-1073 VAR LTA 7R CV on my T-Mobile 640 LTE then used the OTC updater tool from Microsoft to push the update to my phone. I only use it for a Wi-Fi device though so I don't know if cell/data works or not.
So I've unlocked the bootloader on my Lumia 535 the first time through a miracle, made a full backup using Win32DiskImager (I did some tests and didn't want to lose my DPP partition like I did with the L520), and then I flashed the default FFU (to go to stock WP8), and now WPInternals can't find any flashing profile. I've tried more options from the commandline of WPInternals, but still can't do it. So does anyone have any clue if I can, and if yes, how?
