Question about downloading vcreg etc
I decompress the zipfile but there is no xap file in it. is it supposed to be in the zip file?

Hi there! You don't even need vcreg! You can simply do it with Interop Tools.

1. Copy the file to your phone and install it from there (if nothing happens and it does not get installed, then first install all "dependencies" in the app package) and try again
2. Open the app and go to "Registry Browser"
3. Change the needed parameters
4. Bam! You can install Redstone!

Well, I actually found a xap file but it will refuse to deploy. So, I will try your part. Thanks!

I have tried all of these steps. But after completing all the processes Upgrade Advisor tells that Windows 10 update isn't available for this phone. I used the values of Lumia 950 XL (Single sim).

All my research lately said that 512MB devices (e.g. Lumia 520) could never go past 10586. I don't remember how exactly but I have a Lumia 520 which somehow got stuck at 14393.1066. Until today I had no luck with RS2 builds but the recent announcement by Microsoft that "unsupported devices can use RS2 at own risk" or whatever it actually said got me to thinking I should try again.

A quick browse of the Microsoft Update Catalog searching "10.0.15063.251" shows three updates available: for NTN-FI, ELI-FI and 000-FI based devices. No mention there of specific model number variants at all but drilling down the details shows requirement of "Windows Mobile 10 Production: Approved RS2 Device Targeting" and (OSVersion >= 10.0.14393.0 or < 10.0.15063.251) so I decided to try one of those.

I already have the Interop Tools registry browser on the phone from previous attempts.

In HKLM\System\Platform\DeviceTargetingInfo I made the following changes:

PhoneHardwareVariant = RM-1085
PhoneManufacturer = MicrosoftMDG
PhoneManufacturerModelName = RM-1085_11302
PhoneMobileOperatorName = 000-FI
PhoneModelName = Lumia 950 XL

Then in Windows Insider settings I selected Release Preview.

Behold, my 512MB Lumia 520 has downloaded "Windows 10 Technical Preview for phones (10.0.15063.251)" and "Insider Release Preview configuration update" and is currently preparing to install. I'll post back later after it either fails or succeeds.

Side note: during the time I've had 14393 on this phone it has been very sluggish and many apps crash randomly. I suspect this is because of the tiny memory available.

I can confirm that values for Lumia 950 XL don't work anymore if you are trying to download windows 10 on an unsupported phone. Use values for Lumia 830 if above is the case for you.
Use this website as a reference: Use values for Lumia 830 from here
