"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.

ATIV SE - Cant get it interop Unlocked.

I have a ATIV SE which i did at one point have it running windows 10 after i got working in win 8.1 with it being interop unlocked but i had an issue where it would not get SMS on optus in AU.
So i have flash it back to 8.0 and upgrade and try to get it interop unlocked but nothing seems to work.
I have used Custom FPD V3 to get to some of the registry but that wont even load now.

Lumia 521 downgrade

Some time ago to buy the Lumia 521 which had the windows 8 version after upgrade to version 8.1 did not work to complete the interop process.
I have two questions:
1. is possible do windows downgrade to 8?
2. Is possible complete the interop process and unlock the wp with windos 8.1?
This is my first Nokia Lumia.
Using android all was easy, in special with my sidekick 4g. :crying:

1. flashed ffu 8.0 with wpinternals.
2. wpinternals make interop unlock: 8.0-10 mobile( if have ffu)

Thank you reksden for your answer.
I can't find the ffu to download the room for 8.0.
The wpinternals is available in the forum but not found information about fuu.
Is possible request again your help with any link or aditional information...

Hello. Can you help me? Can you tell me how to unlock T - Mobile Nokia Lumia 521? Please reply. Thanks

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.
