How do I downgrade to PORTICO GDR1?

[aziouazrayes]

Hello.
You might ask why would I do such a thing! Well, because of the post processing bug that gives the images a tint of yellow\green. It was first introduced in the amber update. Then came black update and I thought it will take care of it but no. Now I'm on WP8.1 (STILL BLACK) and it's there. I keep waiting for the cyan firmware to update but it seems it's taking a long time and I had it with the quality of the pictures.
PLEASE, CAN ANYBODY TELL ME HOW TO DOWNGRADE TO PORTICO.

My phone is country variant so I guess that means unlocked so I can put another unlocked PORTICO ROM from another country (that's my guess anyway).

I APPRECIATE ANY HELP. THANK YOU.

I don't think that Portico was around for the 520 (I may be wrong on this, but I thought it launched with Amber) so I don't think it would be possible for that particular phone. Maybe someone else here knows more, but I think you may be out of luck on this one.

When I first bought it, it was on portico. I know because I'm a geek.

Thank you for your feedback.

Ah, ok, I could've sworn that WPCentral said something about it launching with Amber (maybe because by the time it launched in the US, it came with Amber?) idk, but if it did come with Portico, then you should be able to just download the Nokia Care Suite and flash it that way.
