[Windows 10 Mobile] BennoMP:
While the Nokia Lumia 530 isn’t officially supported, it’s still possible to get Windows 10 mobile running on it. At the time of writing, it has become a bit tricky to get it to work, since most official Microsoft tools are discontinued and will therefore not work. I will be linking the files which I’ve used. The credits to the people who made or shared the tools and guides I used will be at the bottom of this guide.

Note that I am not responsible for any damage made. Proceed at your own risk!

Prerequisites:

- A Nokia Lumia 530 running the Windows 8.1 Denim Update (will be referred to as "device")

- A stable Windows 7 system or VM, with .NET Framework 4.5.x or 4.6.x (on Windows 10, the IUTool will fail to synchronize, hence this requirement)

- An internet connection that can handle a download of approximately 2GB data on the computer and about the same on the phone

- A good USB cable (a flimsy one with a loose fit could brick the device while it’s updating)

- The programs linked below

First part of the installation:

1. Make sure the device is fully charged. If it’s not fully charged the device could get (soft-)bricked.

2. Factory reset the device, so you have as much storage as possible available on the device. After the reset is done, leave it at the language selection screen, because it doesn’t do anything there.

3. Extract HCTSW_WXMSOUP_V5.3beta6.update.lzma2.7z with 7zip or whatever you prefer.

4. Download the Visual C++ libraries from here: https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/ and run the install script.

5. The next thing you are going to do is download the updates, push them to the device and install them. This will take some time, but it depends on your internet connection for the most part. The files will be downloaded from the official Microsoft servers. Now here’s what to do: open run_en.cmd and follow the steps. These are pretty clear, so I don’t think I need to point all of them out here. It will open a webpage where you can download WDRT, you will need to install that for the tool to work.

6. Now you can move on to the second part.

Second part of the installation:

In this part of the installation, you will be updating the device from version 1511 to the latest available build, which should have a working Microsoft store.

1. The setup of the device. The version that just got installed doesn’t have a lot of options yet, including language packs. If you have a device that’s not English United States, the keyboard will bug out on setup, because it’s trying to access a language pack that doesn’t exist. Therefore, the first step, setting the language should be English (United States), so the OS itself won’t bug out. Once you’ve set the language (it will prompt to reboot, do that), you can go through the rest of the setup. Don’t log it into your Wi-Fi, don’t log it into your Microsoft account and don’t turn on automatic app updates. It’ll say it needs to set up apps, that takes some time but eventually you’ll get to the home screen. Now is when you need a few tools, which brings us to step 2.

Now is a good moment for me to point out that, if you have a non-English-US device, the keyboard for another language is still "installed". It can be removed by holding it in settings -> time and language -> keyboard and choosing “Delete”.

2. Installing Interop Tools. In order to get updates, you’ll need to modify your device a bit. This won’t be very hard, but it involves some registry modifications so you’ll have to pay close attention.

Go to settings -> update and security -> for developers and enable developer mode, so you can sideload the Interop Tools (Linked below). Copy the contents of the Interop Tools zip to the device first. Then, go to the file manager on the phone and go to the directory where you put the files. INSTALL THE DEPENDENCIES IN THE \ARM FOLDER FIRST, THEN THE INTEROP TOOLS FILE ITSELF! Check if the Interop Tools installed on the “all apps screen” and get ready to open it.

3. Modifying the registry. Open Interop Tools and tap the

“This Device”

button. This will bring up a menu.

3.1. Tap the menu button on the top left corner, then select

“Modify Registry”

. In the

“Registry Key Path”

, put SYSTEM\Platform\DeviceTargetingInfo. Then, put PhoneManufacturerModelName in the

“Registry Value Name”

box and tap the

“Read”

button at the bottom. You’ll see some text appear in a box. This will need to be edited to the following value: RM-1089_1048. After you did that, tap the

“Write”

button.

3.2. Now put PhoneModelName in the the

“Registry Value Name”

box and tap

“Read”

again. Now change the value to Lumia 535 and tap “Write”.

3.3. Exit out of Interop Tools and go to the next step.

4. Logging in to the Wi-Fi and checking for updates.

4.1. Logging it in to the Wi-Fi. Go to settings -> network & wireless -> Wi-Fi and choose your network. Easy peasy probably.

4.2. Checking for updates. This is the part that always went wrong with me, because of storage limits (gotta love that 4GB eMMC). But if I’ve explained this well enough, you might not have to do a lot of weird stuff. Oh well, to the instruction we go. Go to settings -> update and security -> windows update and check for updates. This will take a while! Keep it on wall power because updating can only be done at 40% or more at this point. I got two updates: from 1511 to early 1607 and from that to late 1607. Maybe you can get a newer version with WDRT or OTC but I doubt that to be honest.

Hooray! Now you should have a fully functional Nokia Lumia 530 with Windows 10 mobile!

PS: If you brick the device, the WDRT can restore it. If it just puts it in flashing mode, you can use Windows Phone Internals to download and flash a ROM. That tool can be found here: https://www.wpinternals.net/index.php/downloads/doc_download/46-wpinternals-2-8-zip
