Is it possible to downgrade from 8.1 Update 2?

[miguel11691]

I have the prepaid 635 using it on my current account and i converted it to 635 Postpaid update 2 firmware... i wanted to debrand it now using these http://forums.windowscentral.com/no...e]-de-branding-t-nokia-lumia-635-**820**.html instructions but it doesn't debrand maybe because im on the latest software... is it possible to revert back to prepaid 635 8.1 and debrand from there or am I stuck on the postpaid update 2 firmware... i tried to downgrade using WPID or Recovery Tool and It wont downgrade...

Anyone?? I also upgraded to Denim+Update 2 using the same method and now trying to debrand.

Maybe we won't be able to debrand until Update 2 comes out for the country variant.

I had my L920 on WP8.1 developer preview and when upgrading to WP10 technical preview it when through 2 phases in the install after the 1st phase it looked like it brought it back to update 1 or 2. It didn't even have the notification center. So I guess its possible. You can always use the Lumia software recovery tool...
