HOW DO I UPGRADE MY NOKIA LUMIA 920 TO WINDOWS 10?

Is it at all possible to install any version of Windows 10 on the Nokia Lumia 920?

I can"t believe this great phone is becoming useless, so I am willing to deploy preview versions or whatever else is available,

Specs from insider app,

First I was told my Lumia 920 wasn"t getting Windows 10, then it got absolutely shut down from insider as well.

Well, this weekend I"ve decided to spend some time on it, and along with some interesting links from
Indrek"s answer, I finally got it.

If - like me - you are looking for a short answer, then the answer is yes, you can have Windows Phone 10 on your Lumia 920. Needless to say, this answer comes with a...

disclaimer

This is not supported by Microsoft, and for a reason. CPU and Memory capabilities of these phones weren"t enough to pass the quality standards so don"t expect the phone to be as fluid, as fast, or even functioning properly as in natively supported phonesSome of the things we have to do may brick your phoneYou"ll need a bunch of applications and configurations so if you"re expecting a turn-key solution, then this is NOT for youBe prepared for hard resets, which means all information gone. So make backups if you have to.

what you"ll need

Your phone"s ROM (I got mine by running WDRT and installing the version available there, then grab it from C:\ProgramData\Microsoft\Packages\Products\RM-821)

how to soft reset

(hold) vol down + power

how to hard reset

Turn your Lumia 920 off.Press Volume DOWN and keep pressing it while you connect the charger until you see an exclamation mark!.Press - in this order - Volume UP - Volume DOWN - POWER - VOLUME DOWN.Your phone will reset and reboot. Pls be patient during the reset process.

Procedure to deploy Windows 10

Hard reset. phone should go to a lower version such as 8.10.12393.890. since you"ll be needing your ROM exported, you may want to use WDRT for this and then grab the rom from the Packages folderWhen your phone boots up, make sure to pick "Custom" settings and disable all automatic updates of apps and system (it"s important that you don"t update the settings extras+info app)Use the ootb phone system update to get the latest available update. minimum required being 8.10.14219.341. I got 8.10.14234.375

We are now basically following the steps from WPInternals (direct copy from "Getting Started"):

Flash a Windows Phone 8.1 FFU - doneRun Windows Update until you have at least version 8.10.14219.341 of the OS - doneRun the Windows Insider tool and update to Windows 10 Mobile, possibly needs to run Windows Update a couple of times for the latest build (I had to chose Insider Fast, otherwise it would not trigger the update)Enable Root Access directly on the phone

Now for the tricky part. For the phones that were not allowed Windows 10 after the anniversary update, you will not be able to get preview builds anymore, so you"ll have to pretend that your phone is actually the 950XL.

For this you"ll have to:

register your phone to be developer unlockeddeploy and run CustomPFD_0600.xapgo to HKLM > System > Platform > DeviceTargetingInfo

What I did was create a table with both old and new values as a backup, then actually write/set the new values for each entry, then reboot the phone.

Key/OldValue/NewValue

PhoneModelNameLumia920Lumia950XL

PhoneHardwareVariantRM-821RM-1085

PhoneManufacturerNOKIAMicrosoftMDG

PhoneManufacturerModelNameRM-821_eu_italy_310RM-1085_11302

With the new registry settings, you should now be able to use the insider app to request a new build. If everything works as expected you will get a prompt to reboot and short after the update will pop. It make take a few attempts and take a while, but it should work. Make sure root access is disabled at this point (if for some reason you have enabled it) or it could block the update.

troubleshooting

Cannot register developer phone device

--> make sure it has internet access

Device Portal greyed out in Windows 10 PC

--> make sure "Developer features" is setup to "developer mode"

Error deploying xap 0x8974006

--> make sure phone is not in lock screen

Errors deploying xap 0x81030110 / 0x81030120 / 0x810310B

--> this issue is typically an unsupported Capability referenced in the MAppManifest.xml file. to work around this, you"ll have to make sure that your phone has an unlocked bootloader. if you still get this, try also enabling root access

Not getting updates (8007000d)

--> make sure phone is not rooted
