    Good day everyone, I'm currently running Lumia Black GDR3 on my lumia 720 philippines variant and I want to downgrade back to GDR1/Portico
    I recently checked the Lumia Black update for Asia pacific countries and i noticed that Cambodia doesn't have the amber/black update, which means its stuck with GDR1. can anyone provide me the product code for this variant?

    the reason I'm downgrading to gdr1 is to restore the camera quality of my phone.

    I've attached sample photos of the default camera with auto settings. (lumia black)

    as you can notice there's the greenish hue, and the image itself isn't that sharp anymore

    :update:

    I've found some other product code that has not been updated to amber/black:
    >059S0T6< >RM-885 ZA RED SWAP<
    Its somehow based in UK? (not really sure)
    I flashed it and it worked, my phone downgraded back to gdr1

    Here are some photos that I took after the downgrade:

    the green/yellow tint or hue is nowhere to be found, and the image looked more crisp than those of the amber/black images.

    Great! These are the pictures this phone should take. Glad for you

    I think I will downgrade my phone tomorrow or the day after tomorrow. Can you please clarify if

    1) 6tag works fine on Portico?
    2) If there is Russian language in this >059S0T6< >RM-885 ZA RED SWAP< firmware?

    Don't think it will come :/

    So I backed up my stuff and wanted to do the downgrade yesterday, but it turns out that I'm not sure how to find ROM that's stuck with the latest version of Portico. Can I ask you how did you find out that >059S0T6< >RM-885 ZA RED SWAP< will not update to Amber/Black? I can't seem to find any hint in Nokia Care Suite or NaviFirm+.

    And there are a few versions of Portico ROMs (as far as I understand - I may be wrong on this one). Is 1030.6409.1311.0001 the latest version of Portico?..

    SWAP turns out to be African telecom company: SWAP - "Welcome to our official website"
    And I figured out how to find out which ROMs are stuck with Portico! Check here if you want: http://forums.windowscentral.com/nok...-versions.html

    I'm pretty sure >059S0T6< >RM-885 ZA RED SWAP< can't be upgraded to amber or black, I've tried it a couple of times, and double checked my "extras+info" if its up to date. As far as I remember, All portico ROMS have the Build ID of 1030.6409.1311.XXXX, while Amber/Black have 30XX.XXXX.XXX.XXXX something... hope you find this a little helpful

    Figured this one out, but it's great to have a confirmation! ;) I've decided to use 059S0T4 RM-885 ZA WHITE SWAP - it's the same ROM you used, just another color. Igave it a thought and decided I don't want to use Claro/ Vodafone/ Telenor ones, because I'm sure they have bloat and restrictions; for some reason I don't think that African telecom company will add any of this. And, above all, Table Mountain looks nice! :D

    Turns out, 059S0T4 RM-885 ZA WHITE SWAP is a United Kingdom ROM! Anyway, there is no bloatware and Amber/Black are not available, I'm happy with it!
