Upgrading Nokia Lumia 1020 to Windows 10 & Project Astoria questions

[Tourniquet]

Hi guys,

Now, here are the problems:
1. I cannot install Lumia Camera from Windows Store on Windows 10 Mobile 10586.1176 (it says the app has been blocked for this device, there is no possibility to download and install it from the Windows Store, download button is greyed out).
2. I tried unlocking bootloader using WPInternals tool (to be able to enable Developer settings and try to sideload Lumia Camera app) but it fails to enter Flash mode :-(
3. What I also didn't know is that HERE Drive+ app (which my father uses for navigation) is no longer working under Windows 10, it says the app is no longer supported :-( I don't know why but I cannot enable voice support in Windows Maps :-( I would at least want to have HERE Drive+ and Lumia Camera apps back
4. I tried rolling back to WP8.1 using Windows Device Recovery Tool but rollback fails :-(

Or how to rollback to WP8.1? Or how to downgrade to 10586.107 to test if unlocking bootloader works from that build using WPInternals?

Thank you in advance!

1) You should be able to download the App from the Store, but you require the right link: https://www.microsoft.com/en-us/p/lumia-...zdncrfhww1
2) No need for unlocking to sideload stuff, but you figured that already out.
3) Yes Here Drive+ and Here Maps are no longer compatible, but Voice Direction is still very much supported in the Windows 10 Maps App. If you really need a better Windows 10 Maps App you might want to upgrade to 14393 aka Windows 10 Mobile Version 1607. That said though: There are modified / old version of Here Drive+ and Maps that do still work on Windows 10 Mobile. I was never interested in them, because for me Windows 10 Maps works great, but there are versions around.
