Windows 11 running on flashlmdd

Running Windows on the LG V50

Rooting your device

Prerequisites

Method 1: Easy method

If you don't have LineageOS installed, use method 2

Boot into Lineage recovery

By holding the volume up + power buttons while the phone is powered off

Flashing Magisk

  • Select Apply update > Apply from ADB.
  • Download magisk.apk and rename it to magisk.zip
  • Use the adb sideload command to install Magisk. Replace path\to\magisk.zip with the actual path of magisk.zip.
adb sideload path\to\magisk.zip
  • Reboot back to Android after it has finished flashing.

Finishing the Magisk installation

  • Find the Magisk app and open it. Let it update if it asks you to update.
  • Once you are able to open Magisk, open it and let it finish the set up. It should reboot after a few seconds.

Finished!

Method 2: Harder method

Use this method if the first one does not work

Setting up Qfil

  • Open Qfil.
  • In "Select Build Type", select flat build.
  • In "Select programmer", select the downloaded firehose.
  • In "Configuration", make sure the "Device Type" is set to UFS.

Boot to EDL

  • Open Device Manager on your PC
  • With the phone turned off, 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.
  • If the device is called QUSB_BULK_CID or has a ⚠️ yellow warning triangle / question mark, and is located in any other category (for example Other devices), you need to install EDL drivers first.
  • To install EDL drivers, extract the contents of QUD.zip somewhere, right click on QUSB_BULK_CID, click on Update driver and Browse my computer for drivers, then find and select the QUD folder.

Making sure Qfil works

  • In Qfil, make sure the correct port is selected. If it says No Port Available, select the Qualcomm HS-USB QDLoader 9008 port.
  • At the top, select "Tools" > "Partition manager", and click Ok.
  • If you see a Download Fail:Sahara Fail error, make sure your cable stays connected and reboot to EDL again by holding volume down + power, then start rapidly pressing the volume up button once the LG logo appears.
  • Once you're back in EDL, try opening the Partition manager again.
  • If it still fails, try to repeat the last step a few times. You can also try rebooting your phone and PC.

Backing up your boot image

  • In the Partition manager, right click on boot_a > Manage Partition Data and press Read Data.
  • Navigate to C:\Users\YOURNAME\AppData\Roaming\Qualcomm\QFIL\COMPORT_#\ and rename the backed up partition to boot.img (make sure it changes the extension).

Reboot back to Android

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

Patching the boot image

  • Copy the boot backup to your phone.
  • Download and install Magisk, then open it.
  • Press Install > Patch a file and select the boot image.
  • Once it's done, copy the patched boot image to your PC and reboot back into EDL.

Flashing your rooted boot image

  • Return to Qfil and open the Partition manager.
  • In the Partition manager, right click on boot_a > Manage Partition Data and press Load Image.
  • Select and flash the patched boot.img file.
  • Do the same thing for boot_b.

Reboot back to Android

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

Finished!
