The Windows 10 April 2018 update has arrived! Get the new Dell XPS 15, starting at $999.99

    Apparently to flash new firmware I need the firmware and a product code. I have a UK Lumia 1020 64GB Black from O2 that's unlocked. The hardware revision is 4.4.6.2. I want to de-brand it so that when Windows Phone 8.1 is released I can get it straight away as an OTA update.

    Having looked through the codes here and here I don't know which one to get. I want the one you'd get if you bought a phone from Nokia's store I guess (for the UK, if that matters).

    Thanks

    From the websites you have linked, the country variant product code for the black Lumia 1020 is 'Euro GB CV Black (059T1V6)'. But you have a 64 GB variant, which might be exclusive to O2. In which case, I do not know if the country variant product code will work.

    As a side note, it is very likely that Microsoft will have a developer preview release for Windows Phone 8.1 as well, so you do not need to flash to a country variant for the updates. However, if you have some kind of aversion to using the preview, I suppose flashing to the CV would be best. I'm hoping someone else can clarify if the regular CV ROM will work for the 64 GB version.

    Thank you, that's helpful.

    I remember with the preview releases for Windows 8.1 you couldn't update to the Release version afterwards. Is Windows Phone the same? I want to be up to date, but with convenience.

    I suppose if one ROM works for 16GB and 32GB it's likely to work for 64GB.

    Previews do not work the same way for WP. You'll be able to install the official firmware release and subsequent updates on top of the preview.

    Of course, I'm basing this on the preview for Update 3 and Lumia Black. Since WP8.1 hasn't been announced yet, I can give no guarantees right away; it shouldn't be different from last time.

    I have a yellow 64gb uk lumia 1020, which I flashed successfully with a "059T4N3 RM-875 VAR EURO GB CV YELLOW" to give me unbranded rom. "CV" is the important letters to look out for.

    Since you got a black version, I guess you should flash "059T1V6 RM-875 VAR EURO GB CV BLACK"

    various post in this forum if you search for it, but I think this helped me flashed me

    Good luck.

    Flashing 059T1V6 worked fine, although it's a really old ROM and doesn't seem to want to let me get any updates.

    EDIT: It's not an old ROM (apparently) it's just all the apps are old and need updating.
