"Re-Brand" AT&T Lumia 640

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.

MetroPCS L640LTE to WM10?

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.

JTAG is the only way to disable the write protection. You could just replace the motherboard, but if the replacement has a Samsung eMMC too then that's a problem because your Lumia will eventually die again.

NEED HELP WITH UNLOCKING NOKIA LUMIA 520

Hi,
I have some problems with unlocking the bootloader in a nokia lumia 520 (carrier locked with wind, italian).
i followed a tutorial on xda developers, but it says:
The FFU-image you selected does not have a supported OS-version. Windows Phone Internals needs to extract files from a supported OS-version. You need to select such donor-FFU. If necessary, you can select an FFU-image for a different model.
could i please know how to fix this??
