apps, tools & mod utilities
Handy apps and tools for sideloading UWP packages (.APPX), running custom scripts, and tweaking the registry.
Must-Have All-In-One Tool
WUT (Windows Universal Tool)
A super handy, completely free UWP app built by basharast that packs a bunch of essential Lumia maintenance tools into one clean interface (with zero tracking or data collection).
Why you should grab it:
Commander Scripts: Lets you run community scripts to clean up or tweak system settings automatically.
Built-in Downloader: Integrated package installer, MEGA client, and batch downloader to grab apps straight onto your phone.
WUT Mini Edition: A lightweight version built for older devices with 512MB/1GB RAM that comes with Project Astoria tools baked in.
Built-in Utilities: Comes with a web browser, media viewer for PDFs and videos, and print setup right on the phone.
Quick tip for WUT Mini: If the app closes when opening a file, tap into the download queue once first, then try opening your file again.
Everything you need to sideload apps, deploy legacy XAPs, or perform a full SPEC-B bootloader unlock using Windows Phone Internals.
Level 1: Basic App Sideloading (No Unlock Needed)
Turn On Developer Mode
If you just want to install custom `.appx` or `.appxbundle` files, you don't need any complex hacksβjust flick a setting on your phone.
Open Settings: Launch Settings on your phone.
Go to Developer Settings: Head to Update & Security → For developers.
Enable Developer Mode: Tap the Developer mode option and confirm the prompt.
β Done! You can now tap `.appx` files in File Explorer or Edge to install them straight onto your phone.
Installing .XAPs & System Mods (Requires Interop Unlock)
Deploying Legacy Apps & Tools from PC
If you want to install older Windows Phone `.xap` apps or deep system mods like CMD Injector, your phone needs to be **Interop Unlocked**. You'll use the PC deployment tool to push them over USB.
Plug In Your Phone: Connect your Interop-unlocked Lumia to your PC using a USB cable. Keep the phone screen unlocked and Developer Mode turned on.
Deploy Your App: • Launch **Windows Phone Application Deployment** on your computer.
• Set the **Target** dropdown to `Device`.
• Click **Browse**, pick your `.xap` file (like **CMD Injector**), and click **Deploy**.
Open on Phone: Once it finishes, the app will show up right in your phone's App List ready to open.
Wireless Sideloading via Wi-Fi
Deploying Apps Wirelessly via Local IP
You can send `.appx` apps over your local home Wi-Fi network without digging out a USB cable.
Turn on Device Portal: Go to Settings → Update & Security → For developers on your phone, then toggle ON both **Device Discovery** and **Device Portal**.
Grab Your Phone's IP: Make sure your PC and Lumia are on the same Wi-Fi. Look under the Device Portal section on your phone to find its IP address (looks like 192.168.1.15).
Connect in PC Browser: Open a browser on your PC, type in https://<your-phone-ip>, tap **Pair** on the phone to grab a 6-digit pin code, enter it in your PC browser, then go to **Apps → Install App** to upload `.appx` files wirelessly.
SPEC-B Lumia Bootloader Unlock (WPInternals)
Unlocking the SPEC-B Bootloader
This guide walks you through fully unlocking the bootloader on supported SPEC-B Lumia hardware using **Windows Phone Internals**. Note: The Microsoft Lumia 535 is NOT supported due to hardware limitations that cause the unlock to fail mid-way.
Install Required PC Drivers & Tools: • Download and install Windows Device Recovery Tool (WDRT) on your PC to get all necessary USB/flashing drivers.
• Download Windows Phone Internals (WPInternals).
Download Device Firmware & Emergency Files: • Connect your Lumia to PC and open WPInternals to find your phone's RM-type and Product Code on the home tab.
• Head to LumiaDB, search for your phone's RM-type or Product Code, and download your matching stock .ffu firmware file.
• Download the matching Emergency Flash Files (.ede / .hex / .mbn) for your device model from the Lumia Emergency Files Archive.
Download Donor FFU: • You can download a donor FFU directly on LumiaDB.
Unlock Bootloader Process: • Select Unlock Bootloader from the left sidebar in WPInternals and click **OK** to reboot the phone into Flash Mode.
• Choose your **Original FFU**, **Emergency File (.ede)**, and your **Donor FFU** from LumiaDB when prompted.
• Click **Unlock**. Never disconnect the USB cable during this procedure!
• The phone will reboot repeatedly during flashing (up to 64+ times, which is completely normal).
• When the phone enters Mass Storage mode and prompts you, perform a **Soft Reset** by holding **Volume Down + Power** until the device vibrates.
• Once second flashing finishes, your device boots back into Windows Phone OS with a success message!
• Just want to install archived UWP apps? → Turn on Developer Mode (Level 1).
• Want to install .XAP files or CMD Injector? → Get an Interop Unlock + Windows Phone Application Deployer on PC.
• Want to send apps over Wi-Fi? → Use Device Portal via local IP.
• Need SPEC-B bootloader unlock? → Install WDRT drivers, grab your stock FFU + Emergency files + Donor FFU from LumiaDB, and run WPInternals.

live store & working apps directory
Where to get software that still works on Windows 10 Mobile in 2026, featuring Live Store and active third-party social apps.
Your Primary App Store
Live Store β Everything In One Spot Active
Since the official Store is long gone, **Live Store** is the place to get apps. It's an awesome community store packed with working apps, games, utilities, and dependency bundles that you can download in 1 click.
Huge Selection: One-click downloads for `.appx`, `.appxbundle`, and legacy `.xap` app files.
No Account Needed: Just open Live Store in your phone's browser or Edge and tap install.
Bundled Dependencies: Downloads all required framework files along with the app so installation goes smoothly.
Got an older phone like a Lumia 920, 1020, 820, or 520 stuck on WP8.1? Here is how to force-upgrade it to Windows 10 Mobile using Universal Updater and simple registry tweaks.
Step 1: Upgrade to Threshold 10586
Push Initial Build 10586 via PC
Legacy WP8.1 devices can't update to final W10M builds in one jump. You have to push the base Threshold build (10586.107) first from your PC.
Prep Your Phone: Make sure your device is running **WP8.1 Update 1 or Update 2** (build 8.10.14219.341 or higher). Plug it into your PC via USB and keep the screen unlocked (WP8.1 connects automatically without needing a developer mode toggle).
Push Update Packages: • Connect the phone to USB.
• Select **Offline update packages** → Pick **10.0.10586.107**.
• Click **Start / Push Packages** and wait for the files to transfer over.
Install on Phone: On your Lumia, open Settings → Phone update and hit **Install**. The phone will reboot to spinning gears and turn on running Windows 10 Mobile build 10586!
Step 2: Registry Spoof Hack
Trick System into Thinking It's a Newer Model
Since Microsoft blocked older 1st/2nd-gen Lumias from official W10M updates, you need to edit registry values to trick Windows Update into thinking your phone is a Lumia 950 XL or 640 XL.
Open Registry Editor: Open Interop Tools, select `Registry Provider` (or `This Device`), and head over to:
HKLM\SYSTEM\Platform\DeviceTargetingInfo
Change Registry Keys: Modify these values to match a newer supported model (like a Lumia 950 XL or 640 XL):
• PhoneManufacturer → MicrosoftMDG • PhoneManufacturerModelName → RM-1085_11302 (or RM-1073_1004)
• PhoneModelName → Lumia 950 XL (or Lumia 640 XL)
Reboot: Restart your phone so the new identity registers across system files.
Step 3: Update to Build 14393 / 15063
Grab Final Anniversary or Creators Update
Check Updates: Go to Settings → Update & security → Phone update on your phone (or use Universal Updater on PC).
Install Build 14393 or 15063: Your spoofed phone will now download **W10M Redstone 1 (14393)** or **Redstone 2 (15063)** cleanly.
Virtual Memory Tweak: After upgrading, open Interop Tools and raise your pagefile size to keep 1GB RAM devices running smoothly without out-of-memory app crashes.
