Upgrading Nokia Lumia 1020 to Windows 10 & Project Astoria questions

[Tourniquet]

EDIT: tested additional three appx/xap files (thank you Tourniquet) and still no luck. Only one managed to install, but it then asks for Denim software upgrade after starting the app.

Btw, is there any difference between installing appx/xap files by executing files on the phone and between deploying them e.g. using Windows Phone Application Deployment tool from Windows?

I'm now playing with deploying apps using Windows Phone Application Deployment tool but getting different errors like 'The parameter is incorrect', or 'Error - 0x81030120' and on some files even an error that 'Device is developer locked. Register for the developer unlock program before deploying the application'. Even though I have enabled Developer settings under security and settings. I'm confused with this.

OK, doing hard reset now (again), to see what will happen. To be honest, this is all so exhausting and so much time consuming.
Thank you all for helping me with this!

I'm sure the biggest mistake I did was not making a backup with WPinternals (I'm 100% positive that I could have unlocked bootloader while phone was still on WP8.1 and then I should have created a full backup image). For some reason the phone refuses to enter Flash mode at this stage, so now I'm pretty much stuck with this build. I just wish if there would be a way to downgrade it to one step earlier to 10586.107 (13080.107) because that build is supported in WPinternals.

Heya,

yes for XAP files you either need the Windows Phone 8.1 Application Deployment Tool (not the 8.0 one) or use the Interop Tools App. With that you can cap unlock your phone and it should be able to install the XAP file just fine (as long as it's not decrypted).

Btw after the hardreset, the Camera App should show up again.

The build you use is not compatible with WPInternals. Why do you still want to unlock it with WPInternals though?
