Windows 11 running on flashlmdd

Running Windows on the LG V50

Installing Windows

Prerequisites

Reboot to fastboot mode

  • With the device turned off, hold the volume down button, then plug the cable in.
  • If the phone in device manager is called Android and has a ⚠️ yellow warning triangle, you need to install fastboot drivers before you can continue.
  • To install fastboot drivers, extract the contents of QUD.zip somewhere, right click on Android, click on Update driver and Browse my computer for drivers, then find and select the QUD folder.

Boot to the mass storage mode image

Replace path\to\massstorage.img with the actual path of the image

If popups show up telling you to format the disks, ignore or close them

fastboot boot path\to\massstorage.img

Diskpart

Warning

DO NOT ERASE, CREATE OR OTHERWISE MODIFY ANY PARTITION WHILE IN DISKPART!!!! THIS CAN ERASE ALL OF YOUR UFS OR PREVENT YOU FROM BOOTING TO FASTBOOT!!!! THIS MEANS THAT YOUR DEVICE WILL BE PERMANENTLY BRICKED WITH NO SOLUTION! (except for flashing it with EDL, which is complicated)

diskpart

Select the Windows volume of the phone

Use list volume to find it, replace $ with the actual number of WINFLASH

select volume $

Assign the letter X

assign letter x

Select the ESP volume of the phone

Use list volume to find it, replace $ with the actual number of ESPFLASH

select volume $

Assign the letter Y

assign letter y

Exit diskpart

exit

Installing Windows

Warning

DO NOT USE 24H2!!!

Replace path\to\install.esd with the actual path of install.esd (it may also be named install.wim or 22631.2861.XXXXXXX.esd)

dism /apply-image /ImageFile:path\to\install.esd /index:6 /ApplyDir:X:\

If you get Error 87, check the index of your image with dism /get-imageinfo /ImageFile:path\to\install.esd, then replace index:6 with the actual index number of Windows 11 Pro in your image

Copying your boot.img into Windows

  • Drag and drop the rooted_boot.img from the platform-tools folder into the WINFLASH disk in Windows Explorer, then rename it to boot.img

Installing drivers

  • Unpack the driver archive, then open the OfflineUpdater.cmd file (if an error shows up, run OfflineUpdaterFix.cmd instead)

If it asks you to enter a letter, enter the drive letter of WINFLASH (which should be X), then press enter

Important

After booting into Windows later in the guide, reboot back into mass storage mode and open OfflineUpdater.cmd again to reinstall drivers. GPU drivers do not get installed properly otherwise.

If you get an "Registry hive needs transaction logs" error when doing so, please join the Telegram chat and write #hive for instructions on how to solve this.

Create the Windows bootloader files

If any error shows up, such as "Failure when attempting to copy boot files", open diskpart again and assign any new letter to ESPFLASH, then replace the letter Y in the next commands with the letter that you just added.

bcdboot X:\Windows /s Y: /f UEFI

Enabling test signing

bcdedit /store Y:\EFI\Microsoft\BOOT\BCD /set "{default}" testsigning on

Disabling recovery

bcdedit /store Y:\EFI\Microsoft\BOOT\BCD /set "{default}" recoveryenabled no

Disabling integrity checks

bcdedit /store Y:\EFI\Microsoft\BOOT\BCD /set "{default}" nointegritychecks on

Boot into any custom recovery

Reboot your phone by holding volume down + power until it shows the LG logo, then release the buttons. After this boot to any custom recovery again.

Push parted

Make sure your CMD is opened in platform-tools

adb push parted /cache/ && adb shell "chmod 755 /cache/parted" && adb shell /cache/parted /dev/block/sda

Making ESP bootable

Use print to see all partitions. Replace "$" with your ESP partition number, which should be 31

set $ esp on

Exit parted

quit

Reboot to EDL

If you didn't flash the engineering ABL on the previous page, you can skip this step and the next one and simply reboot your device

  • Open Device Manager on your PC
  • Hold volume down + power.
  • After the LG logo appears, while still holding volume down + power, start rapidly pressing the volume up button.
  • Keep doing this until you hear a USB connection sound on your PC, or when Qualcomm HS-USB QDLoader 9008 appears in the Ports (COM & LPT) category of Device Manager.

Flashing stock ABL

Or your IMEI won't work

  • In Qfil, select Tools > Partition manager, and click Ok.
  • Right click on abl_a > Manage Partition Data and press Load Image.
  • Select and flash the abl_a file in C:\Users\YOURNAME\AppData\Roaming\Qualcomm\QFIL\COMPORT_#\
  • Do the same thing for abl_b.

Reboot back to Android

  • Hold volume down + power until it shows the LG logo, then release the buttons.

Last step: Setting up dualboot
