Yes, Now it is possible to unlock a Windows Lumia Phone for Root Access and run custom ROMs.
Both Microsoft as well as Nokia have made Windows Lumia smartphones difficult to break into at a low-level by locking down their bootloaders, but a software hacker, who go by the name HeathCliff, has just proven that it is not impossible.
HeathCliff has released an excellent tool called «Windows Phone Internals» that allows Windows phone owners to unlock their smartphone’s bootloaders, gain root access and even create and run custom ROMs.
What’s more interesting is the tool supports «most versions of Windows Phone 8.1 and Windows 10 Mobile«.
HeathCliff is very well known XDA Developer and one of the Windows Phone legends. On Windows Phone part, HeathCliff is loved mostly for the WP7 Root Tools.
Here’s the List of Things Windows Phone Internals can Do
- You can unlock the bootloader of the specific Lumia Windows Phone models, and then enable Root Access
- You can load your custom apps with higher privileges and without sandboxing in Windows Phone OS.
- You can create Backup images of your phone and can also access the file-system in Mass Storage Mode.
- You can even install your custom ROMs.
You can also watch the video provided by HeathCliff, showing what the tool is capable of doing.
Models Supported by Windows Phone Internals Tool
Here’s the list of Lumia Phones Supported by the tool right now:
- Lumia 520, 521 and 525
- Lumia 620, 625
- Lumia 720
- Lumia 820
- Lumia 920
- Lumia 1020
- Lumia 1320
How to Get Started?
Here’s the introduction video for you to get started with Windows Phone Internals:
Should You Root Your Phone?
However, I would caution against using this tool to root Windows phone for those who do not understand the underlying architecture of their Windows Phones and Windows 10 Mobiles.
Rooting your phone gives you complete control over the OS, but that power can also be misused if you’re not careful.
Heathcliff also states that after a tweak is completed, you should unroot your device to reduce the chance of malware or other bad stuff making their way on.
Using the tool without proper inspection could also result in damaged and unrecoverable data, for which neither The Hacker News nor I will be responsible. So please be careful before rooting your Windows Phone.

Windows phones have long been regarded as secure and robust devices, but they often fall short when it comes to customization and flexibility. Rooting is a process that allows users to gain administrator-level access to their device, enabling them to modify system files, install custom software, and overcome limitations imposed by the manufacturer. While Android devices have long been popular among rooters, Windows phones have traditionally been more challenging to root.
Understanding Rooting And Its Implications
Before we dive into the process of rooting a Windows phone, it’s essential to understand what rooting entails and the implications of doing so. Rooting a device allows users to gain superuser access, which enables them to:
- Modify system files and settings
- Install custom software and apps not available on the Windows Store
- Override limitations imposed by the manufacturer or carrier
However, rooting a device also comes with its risks. It can:
Potential Risks Of Rooting A Windows Phone
- Void the device’s warranty
- Compromise security and make the device more vulnerable to malware
- Cause instability and crashes
- Brick the device (render it unusable)
Despite these risks, many users are still eager to root their Windows phones. In the past, rooting a Windows phone was nearly impossible, but recent developments have made it slightly more achievable.
The answer to this question is complex. While it is technically possible to root a Windows phone, the process is not straightforward, and the risks are significant. Windows phones run on a variety of operating systems, including Windows Phone 7, Windows Phone 8, and Windows 10 Mobile. Each OS has its unique security mechanisms and architectures, which make rooting challenging.
Rooting Windows Phone 7 And 8
Windows Phone 7 and 8 use a more traditional Windows CE-based architecture, which makes them slightly more susceptible to rooting. However, these devices are no longer supported by Microsoft, and the rooting process is often cumbersome and unreliable.
Rooting Windows 10 Mobile
Windows 10 Mobile is a more modern operating system that uses a Universal Windows Platform (UWP) architecture. This makes it more challenging to root, as the UWP architecture is designed to be highly secure and sandboxed. However, some developers have managed to exploit vulnerabilities in the operating system and create rooting tools.
Interop Unlock and Rooting Tools
Interop Unlock is a technique used to bypass certain sandboxing restrictions on Windows 10 Mobile devices. By exploiting vulnerabilities in the operating system, developers can create Interop Unlock tools that allow users to access certain system files and settings. While these tools are not full-fledged rooting tools, they can be used to install custom software and modify system settings.
Some popular rooting tools for Windows 10 Mobile include:
- Interop Unlock by XDA Developers
- Root Tool by Windows Central
- UWP Root by Reddit’s r/WindowsPhone community
However, these tools are often unstable and can cause issues with the device. Moreover, Microsoft has implemented various security measures to prevent these tools from working, including:
Secure Boot And Other Security Measures
Windows 10 Mobile uses Secure Boot, a mechanism that ensures the operating system boots securely and prevents unauthorized code from executing. This makes it difficult to install custom software or modify system files, as the device will refuse to boot if it detects any tampering.
Microsoft has also implemented other security measures, such as Sandbox-based app isolation and kernel-mode sandboxing, which make it challenging to root a Windows phone.
Alternatives To Rooting
While rooting a Windows phone is a tempting proposition, the risks and complexity involved make it a daunting task for many users. Fortunately, there are alternative ways to customize and enhance your Windows phone experience without resorting to rooting:
Third-Party Apps And Software
Users can install third-party apps and software from the Windows Store, which can provide additional functionality and customization options. Some popular third-party apps include:
- Task Manager by Microsoft
- Winetricks by the Wine Project
- Office Lens by Microsoft
Developer Tools And SDKs
Developers can use the Windows SDK and other development tools to create custom apps and software for their Windows phone. These tools provide a more controlled and secure environment for development and can be used to create a wide range of custom apps and software.
Conclusion
While rooting a Windows phone is technically possible, the process is complex, and the risks are significant. The lack of support from Microsoft and the security measures implemented in Windows 10 Mobile make it difficult to root a Windows phone. However, alternatives such as third-party apps, software, and developer tools provide users with more controlled and secure ways to customize and enhance their Windows phone experience. As the Windows ecosystem continues to evolve, we may see more options for rooting and customization emerge. However, for now, users must weigh the risks and benefits of rooting their Windows phone and consider alternative solutions to achieve their desired level of customization and flexibility.

Root Access allows you to load your own homebrew software onto the phone with high privileges. Apps can escape from their sandboxes. The tool can also create backup-images of the phone and access the file-system in Mass Storage mode. The tool supports most versions of Windows Phone 8.1 and Windows 10 Mobile. For a complete list of supported phones and Operating Systems have a look at the Getting Started section of the tool.
The download package also contains an SDK, which helps you to easily access the filesystem and registry on the phone from your own homebrew app.
The tool, SDK and video’s are available on my new website:
www.wpinternals.net
Update december 23rd:
Windows Phone Internals version 1.1 is released. It has a fix for the audio-issue when Root Access is enabled and it supports Root Access on the latest Windows 10 Mobile build 10.0.10586.36. You can find the new version of the tool in the Download section on wpinternals.net
It seems there were extra integrity checks for playing media. I fixed this for audio-playback. I will create a generic fix later, but this will work for now. If you already have Root Access and you experience the Audio-issue, just «Enable Root Access» again on the phone.
Update december 29th:
A small update this time. Changes in this version:
- Compatibility improvement for Windows 7. In previous versions «Enable Root Access» could result in «Failed to enable Root Access on MainOS».
- «Restore bootloader» now uses a different Flashing interface. Previously, when you restored the bootloader, you were forced to do a full flash afterwards. With this new method you can keep your current Windows Phone installation. Remember that you need to disable Root Access before you restore the bootloader.
- Many small fixes and tweaks.

If your question is not answered here, please watch my instruction video’s and read the «Getting started» section in my tool. I spent a lot of time to explain everything. If you have more questions, they are probably already answered there.
Can we run Android on Lumia now?
Why people ask this is beyond me. If you want Android, buy an Android phone. If you still want it, it will be a big challenge. You can remove UEFI, EFIESP, MainOS and Data partitions and then add hboot and other Android partitions. But then you would still need Android drivers for the Lumia components.
Which Lumia’s are supported by the tool?
Lumia 520, 521, 525, 620, 625, 720, 820, 920, 925, 928, 1020 and 1320 are supported. These bootloaders can be unlocked.
Which OS versions are supported?
For these OS versions Root Access can be enabled. To enable Root Access, the bootloader must be unlocked first.
- 8.10.12393.890
- 8.10.12397.895
- 8.10.14219.341
- 8.10.14226.359
- 8.10.14234.375
- 8.10.15116.125
- 8.10.15148.160
- 10.0.10512.1000
- 10.0.10536.1004
- 10.0.10549.4
- 10.0.10581.0
- 10.0.10586.11
- 10.0.10586.36
I will add support for new versions when they get released.
Why are other Lumia’s not supported?
Other Lumia’s have different CPU architectures. And these come with different bootloaders. Some of my hacks depend on the implementation of these bootloaders. Some of my hacks won’t work on different bootloaders. I need to find new hacks for these bootloaders. I will try that, but I can’t predict when that is ready. The tool has implemented all the basics. So adding new hacks will be easier.
Why are other brands not supported?
Same reason. Some hacks work different. I will try to add support for other brands. But I don’t know when it is ready.
I need Emergency Flash Loaders. Where can I get them?
This search should yield relevant results:
https://www.google.com/search?q=%22lumia%22+%22emergency%22+%22hex%22
I need an Engineering SBL3. Where can I get it?
This search should yield relevant results:
https://www.google.com/search?q=%22engineering+sbl3s%22
You can download a full Engineering ROM or a separate SBL3 file. If you select an FFU file in the tool, the tool will extract the SBL3 from the FFU. SBL3 contains hardware-profiles of the phone and it initializes the hardware. Therefore you should only use an alternative SBL3 if it came from a phone that is at least the same brand and CPU architecture as your phone.
I can’t find a matching Engineering SBL3. Can I still unlock my phone?
Yes. The alternative SBL3 is optional. You can still unlock your bootloader and flash Custom ROM’s. But you will not have Mass Storage Mode. So you won’t be able to enable Root Access directly on the phone or make a full backup-image of the phone. But you can still flash Custom ROM’s and enable Root Access on the Custom ROM’s. Use the second method from my «Unlock» video.
I unlocked my phone and now my audio is gone. Why?
This is an issue with Root Access in Windows Phone Internals 1.0. Update to Windows Phone Internals 1.1 and then choose «Enable Root Access» again.
Can I SIM-unlock my phone with this tool?
No. SIM-unlock is illegal in some countries. I don’t support SIM-unlock.

also, it isnt really important, but you should in your software under getting started maybe link the «windows device recovery tool» instead of the abandoned «lumia software recovery tool». anotherthing: windows startscreen gives me a warning if i start the programm as the publisher of the tool is unknown and chrome warns me too that the downloaded archive from your website could probably be a virus.
other than that: awesome. thanks
