Tools

WPInternals[1]

WPInternals is an open-source tool by Heathcliff74 and gus33000 that allows you to perform tasks like unlocking bootloaders, flashing or backing up firmware, and USB mass storage on most Lumia Windows Phones. The source code is available on GitHub and it runs natively on Windows.

Windows Device Recovery Tool

The Windows Device Recovery Tool (WDRT) was a proprietary tool by Microsoft which let you recover firmware of Windows Phone and HoloLens devices. It runs natively on Windows.

The WDRT was discontinued in late 2024. An offline version can be downloaded from Microsoft (direct download) and the command line utilities included can be used to restore FFU files to Windows Phones.

Guides

Unlocking bootloader

Download WPInternals and Windows Device Recovery Tool.

WPInternals is a tool designed to unlock the bootloader and/or secure boot of select Lumia devices made by Nokia and Microsoft.

Windows Device Recovery Tool is installed because it automatically installs all the drivers WPInternals will need.

Once you have installed both tools, Click on "Unlock Bootloader" and follow the instructions to unlock your phone's bootloader. If you run into issues, you may need to use a different USB port (USB 3.0 controllers are known to cause issues) or a different computer.

Enabling Boot Menu

• Make sure your phone is in mass storage mode and that EFIESP is mounted.
• Find where EFIESP was mounted, Windows will either mount it in MainOS/EFIESP or with a letter (J:, L:, etc)
• Anything inside <> needs to be filled in by you, for example: <EFIESP> becomes K:\EFIESP if K: was MainOS and EFIESP was mounted at MainOS/EFIESP
• Open cmd as Administrator and run the following commands:
• Turn on displaybootmenu: bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /set {bootmgr} displaybootmenu on
• Set boot menu timeout to 10s: bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /set {bootmgr} timeout 10
• Set displayorder: bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /displayorder {default}

Extra steps for phones with a camera button:

• Devices with a camera button, you can make it so you can choose the boot option using volume keys and camera to select.
• Unfortunately there is no known way to make power button be select, so phones without a camera button can't use this.
• bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /deletevalue {bootmgr} customactions
• bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /deletevalue {bootmgr} custom:54000001
• bcdedit /store <EFIESP>/efi/Microsoft/Boot/BCD /deletevalue {bootmgr} custom:54000002

Adding a new BCD entry

• Make sure your phone is in mass storage mode and that EFIESP is mounted.
• Find where EFIESP was mounted, Windows will either mount it in MainOS/EFIESP or with a letter (J:, L:, etc)
• Anything inside <> needs to be filled in by you, for example: <EFIESP> becomes K:\EFIESP if K: was MainOS and EFIESP was mounted at MainOS/EFIESP
• Open cmd as Administrator and run the following commands:
• Creating a new entry: bcdedit /store .\BCD /create /d "<NAME>" /application BOOTAPP
• Copy the GUID (the squiggly brackets and the stuff inside)
• Set the efi path: bcdedit /store .\BCD /set <GUID> path <EFIFILE>
• Set the partition the efi file is in: bcdedit /store .\BCD /set <GUID> device partition=<EFIPART>
• Turn on test signing: bcdedit /store .\BCD /set <GUID> testsigning on
• Turn off integrity checks: bcdedit /store .\BCD /set <GUID> nointegritychecks on

Extra steps for phones with a camera button

• Add BCD entry to display order: bcdedit /store .\BCD /displayorder <GUID> /addlast

Extra steps for phones without a camera button

• We need to set a volume key to boot our new BCD entry
• custom:54000001 is for volume up, custom:54000002 is for volume down
• Set the volkey to boot our bcd entry: bcdedit /store BCD /set {bootmgr} <VOLKEY> <GUID>

Unbricking devices on EDL mode(QHSUSB_BULK)

This guide is for Spec B devices only. While this process, make sure WPInternals is not running in the background.

• Install the WDRT if you don't have it.
• Connect the device to the PC and check how it's detected from device manager. If device is detected as "QHSUSB_BULK" on "Universal Serial Bus Devices", then it's fine. If it's detected as "Qualcomm HS-USB QDloader 9008" on "Serial Devices", select update driver and install "Care Suite Emergency Connectivity" driver. Disconnect device and remove battery after updating driver.
• Open a CMD and cd into WDRT directory (C:\Program Files (x86)\Microsoft Care Suite\Windows Device Recovery Tool for 64bit, C:\Program Files\Microsoft Care Suite\Windows Device Recovery Tool for 32bit)
• Go to LumiaDB (or similar) and download FFU file and emergency files (.ede and .edp) for your device.
• Type thor2 -mode emergency -hexfile [path to .ede file] -edfile [path to .edp file] to CMD and hit enter, wait for it flashes. When you get FFU_PARSING_ERROR, that means it flashed emergency payload and you can continue.
• When you get red flashing screen, type thor2 -mode uefiflash -mode uefiflash -ffufile [path to .ffu file] -do_full_nvi_update -do_factory_reset and wait for it to flash FFU.
