[Windows 10 Mobile] WolfCobra:
Hello? Anybody still around? I hope so. I need some advice/help. I will bold my questions so they are easier to reference.

I have two identical Lumia 1020’s that I upgraded to Windows 10 using this procedure posted by hikari_calyx https://xdaforums.com/windows-10-mobile/guide-win10-mobile-offline-update-t3527340 and summarized here https://forums.windowscentral.com/windows-10-mobile-how-guides/452310-how-offline-update-unsupported-lumias-8-1-latest-10586-xxx-14393-xxx-15063-xxx-build.html

This procedure got both phones to 10586.107. However, one phone was able to get updates to Redstone automatically. The other is stuck at 10586.107. The stuck phone is my daily driver and the phone that I’d like to be on Redstone. The one that actually made it to Redstone is a spare and has mechanical issues. It was the phone that I upgraded first to familiarize myself with the upgrade process. The phones are identical except the one that fully upgraded does not have an active SIM.

Since the upgrade I’ve been spending many hours in the forums and on youtube looking for reasons why my one phone might not be getting updates and also for ways to force updates. Most posts are very old and maybe I’m late to the party, but I’d like to get this other phone upgraded.

Here’s what I’ve tried:

1)	Since the phones are 1020’s I had to modify the “OEMInput.xml” file to get past a bug in the update process. Following this guide https://xdaforums.com/windows-10-mobile/guide-how-to-fix-windows-update- issue-t3697172, I was able to continue getting updates on the one fully upgraded phone. Since I cannot get updates at all on the other phone, I don’t know if this will work for

it yet.

2)	I checked that all my registry settings are properly set for my model:

PhoneManufacturer=”MicrosoftMDG”

PhoneManufacturerModelName=”RM-1085_11302”

PhoneModelName=”Lumia 950 XL”

PhoneHardwareVariant=”RM-1085”

I examined the source code for DHTUpgradeAdvisor and I think this is all that should be set.

3)	I tried the Windows Insider App, to be sure I’m getting updates but it when I click the “Get preview builds” it throws a Server Error “A connection error prevented us from downloading programs for you. Please check the date/time of your device and its network connection and try again.”

Of course my date time is correct.

I tried reinstalling the Windows Insider App. Same problem.

I did notice a difference between the phones here. When I open the Windows Insider App on the phone that fully upgraded it shows “Go to Settings” instead of “Get Preview Builds”. The phone that fully upgraded has a “Windows Insider Program” link under Settings>Update&Security. The phone that refuses to upgrade does not have this link. The app does not work on either phone. Why is there a difference between the phones here? How can I get the Windows Insider App working again?

4)	I’ve tried to add the provisioning for Mobile Enterprise, but I can never get it to show “Enterprise” in the about section. The package does appear in provisioning. I’ve tried multiple .ppkg files. None have worked.

I did see in a post that you must opt out of the Window Insider Program. I’m not sure how to do this since I cannot get into the Windows Insider App. Also it mentions that the SIM should be removed. I did not try this.

Is there a registry setting or something that can be modified to change the update rings or opt out of the insider program? Or does the insider app associate my phone with my Microsoft account and I need to login to my Microsoft account and somehow disassociate it there? Does the SIM really need to be removed?

5)	I had the idea to make an image of the fully upgraded phone and then dump it into the non-upgraded phone and then hard reset it and recommission it. I tried to make an image with Windows Phone Internals 2.8. I am able to unlock the bootloader of the upgraded phone but I’m not able to get it into Mass Storage mode in order to make an image. I’m not sure what I’m doing wrong. I have only a basic idea of the phone hardware architecture so I don’t even know what to try next to get an image. Any ideas?

Is this idea even feasible? Is it possible to take an image from one phone and dump it into another effectively cloning the first one? I wasn’t sure if there would be problems with hardware (MAC addresses, etc) mismatches with the software or not. Anyone tried this? Should I pursue this more?

6)	The next option is to pump the updates into the phone offline. I am not clear on how to do this. Of course I know how to use iutool (as long as it behaves) since I used it to get the phones to 10586.107.

There is a guide to updating offline here https://xdaforums.com/windows-10/windows-10-mobile/w10m-builds-update-links-collection-cab-t3234805. It looks like this is mostly a guide to capture the cabs for posterity. For upgrading, it’s not clear to me how to begin. There are links to some update cabs in the post, but also this link: https://www.catalog.update.microsoft.com/Search.aspx?q=RM-1085_11302. It has info, but I don’t know what I’m looking at. This is where I get confused. Are these even the cabs I need? Are these update cabs independent of the phone model? Can I just grab the cabs within those links and copy them to my PC and then update my phone using iutool? Do I need to do all the updates in order or can I skip ahead? How do I know which ones I can skip over? What is 000-88 based vs 000-HK based vs CTM-MO based devices? Do I use iutool as I did before (keeping the same files in place and just overwrite the cabs with the new ones)? I see these questions partly answered in the subsequent posts, but I’m still unclear of the cabs to use and the order. This method seem like it’s for people smarter than myself and has a high risk of trial and error and brick potential. I’d rather figure out how to get the proper update pushed over-the-air if possible, but if someone has done this method on a 1020 successfully I might try it.

I would prefer to not have to do hard resets or rollbacks if possible since I feel like I'm very close to getting it to work (It worked on my other phone naturally).

Thank you to anyone who is able to answer any of my questions and give me advice on which of the above methods is best to pursue!

I’ve never posted to a social media site such as this, so if I’ve posted wrongly I apologize.

Your friend,
