Upgrading Nokia Lumia 1020 to Windows 10 & Project Astoria questions

[Tourniquet]

0

Now, some of the questions from my side (I'd appreciate if anyone can answer) before I start looking further into it and trying out the upgrade procedure:

1. The Lumia 1020 phone OS Build is 8.10.14226.359, is this build supported 'as from version' for the upgrade to Windows 10?

2. Which Windows 10 build will the phone be upgraded to using ToUrNiQuEt's method (unfortunately I still don't have any forum access rights to read more about it on https://www.wpvision.de/tourniquet/)? Are there any selectable OS build options?
Asking cause of Project Astoria, I read here (https://www.windowscentral.com/android-a...nd-caveats) that Astoria is only supported on two Windows 10 builds (10166 and 10536). So, my question is, which Windows 10 build am I getting using ToUrNiQuEt procedure?
As I would like there would be then an option to install Whatsapp afterwards, as the support for Whatsapp will end soon on Windows phones.

3. Will all the apps be functioning correctly after the upgrade as they used to, are there any known bugs / issues (e.g. WiFi connectivity, Bluetooth, battery drain issues, phone restarts?), and most importantly will the camera be working as smooth as before and able to take both 36 MP and 5 MP photos? I read somewhere that after the upgrade to Windows 10 only High resolution photos (36 MP) were possible to take with the camera.

That's it for now from my side, if I think of anything else, I'll make sure to post it here :-)

Thank you all in advance for any suggestions and answering any of the questions I might have.

P.S. Merry Christmas and a Happy New Year (in advance) to all forum members here :-)
P.P.S. I hope I understood the rules correctly, and that I'm posting this under the right Forum

Heya and welcome

1) To be able to upgrade from Windows Phone 8.1 you need at least Build 8.10.14219 and the latest firmware update. In some cases and depending on the mobile the Lumia 1020 sometimes did not get the latest (Denim I think) firmware.

2) If you use the "normal" PhoneUpdater you can basically only select Windows 10 Mobile Version 1511 Build 10586.107 (13080.107). After you updated you can then select a couple of newer Builds from Version 1511 or Builds from Windows 10 Mobile 1607 (14393.xxx). As soon as you're on 14393.xxx PhoneUpdater will allow you to select 15063 aka Windows 10 Mobile Version 1703.

3)
With Windows 10 Mobile Version 1511 everything on your phone works as good as possible. That's because it was made for those older phones too.
Starting with Windows 10 Mobile Version 1607 glance screen would not work anymore but in terms of App-Support, Edge, its a much better Version and overall probably more polished.
With Windows 10 Mobile Version 1703+ you will have App rendering issues because Microsoft changed the rendering engine and the GPU driver is not compatible with all Apps. So if you for example want to use the Maps app you might not be able to see streets name or so, or the screen might even be just white.

That said: Version 1703 has still the best Support in terms of Apps. If you're after Apps that will still be the best version. Batterylife is usually not as good though.

There are also some Bluetooth problems I heard about with Version 1607 / 1703 but those are usually fixed after you've done a hardreset, which is very important anyway.

Regarding the Camera: All you need to make sure is: Keep using the Lumia Camera App not the Windows Kamera App. With the Windows Kamera App you can take photos but only the Lumia Camera App is optimized for the 1020s Camera. As long as you keep using that app. You will have the same great camera expierence you always had. It might be a bit slower because the OS is more heavy but all in all it still works fine.

My recommendation would be: Update to 10586.107 (13080.107) after that update to 10586.1176 (14003.1176) do a hard reset and see how it works. If you're happy with the Apps and Edge (sadly not even Twitter PWA is supported on that old version of Edge), I would probably stay on that Version. If you really need more apps then try out 14393 and only after you're missing some apps I would upgrade to 15063.

Regarding Whatsapp, I have honestly no idea. I would think you might be able to get it via your library in the Store but I'm not sure about that.
