[LG V60 ThinQ Guides, News, & Discussion] crimsonrommer:
Earlier today I was alerted to https://www.cnblogs.com/yanhua-tj/p/15525593.html which has the actual firehose and steps to unlock! However it seems to be in Simplified Chinese so I'll translate it here for you.

The firehose is attached below.

DISCLAIMER: I am not responsible for any damages this may cause as I am merely translating the guide, I am not responsible for you bricking your device because of a missed step so read carefully,

Also, Please backup your data beforehand as this does wipe the phone. Also please note that if you are on android 11 LG Backup will not work after unlocking, neither does the LG Bridge tool.

***IF YOU WANT ANDROID 12, UPDATE BEFORE ROOTING, I HAVE CONFIRMED IT WORKS FINE***

Requirements:

Get QPST Here

Get the FIrehose Here

Engineering Bootloader Here

Adb and Fastboot Here

Qualcomm Drivers Here (When installing make sure to select wwan)

Frp with oem unlock bit set for Verizon Here Not for demo units!

Slight knowledge of the command line

A Brain

Steps:

If you already have it unhidden go to Developer Options under Settings -> System and enable OEM Unlock as well as USB Debugging. If you don't see Developer Options go to Settings => System => About Phone => Software Information and tap Build Number until it either asks you for your password or says you are a developer at the bottom. Verizon Users: You will not see the oem unlock option, we will fix this later in this guide.

2) Get it into 9008 Mode: (This may take several tries)

Make sure you are connected to your computer via USB.

Hold Volume Down and Power until it shuts off

Now here's the tricky part, as soon as the screen turns off, immediately start tapping volume up quickly, but do not let go of volume down and power, if you did it successfully you will see your screen is off but it appears either in Device Manager or Windows plays the Device Connected sound.

Open and Configure QFIL as shown below:View attachment 5452673

After that click Browse and select the Firehose you downloaded earlierView attachment 5452675

Next go to the Tools menu at the top then select Partition Manager (If this errors please reboot back into edl using the steps mentioned above!)

After that wait for QFIL to connect then a new window will pop up. FInd abl_a and abl_b, right click on each and click Manage Partition. First thing you want to do for each is click Read Data. This will back them up in case of anything going wrong. QFIl will tell you where it stores them. Then for each click Load Image and select the Engineering Bootloader you downloaded from before.View attachment 5452679View attachment 5452681

Once you get that done for both abl_a and abl_b click close on both the Raw Data Manager and Partition Manager and wait for QFIL to say Finish Reset to EDL in the logs at the bottom.

Now it's time to get into Fastboot.

Press and Hold Power and Volume Down for 9 seconds

Once you either see it disappear from QFIL or you hear it disconnect from your PC, let go of power, until you see Fastboot Mode on your Phone's screen.

Open the command prompt on your computer.

Once it's in fastboot verify if fastboot can see it by doing fastboot devices, if it can't see it troubleshoot here:

Check your USB Connection

Double check you installed the adb and fastboot stuff from earlier in the post

There may be a chance WIndows doesn't recognize it properly. So follow these steps:

Open Device Manager by doing Windows + X and clicking Device Manager

There may be an already open row that says Unknown Devies

Right click on android and select Update Drivers

Select Browse my computer for drivers

Select Let me pick from a list of available drivers

Select Android Device

Select Android Bootloader Interface

Click Ok on the pop up

Once that finishes double check the phone can be seen in fastboot devices

Now here comes the fun part, unlocking! Please make sure you have your data backed up.

If you are on verizon (and it's not a demo unit)

Make sure you downloaded the file from above for the unlocked frp

Do fastboot flash frp frp.img

Do fastboot reboot and let it boot into android once, no need to set it up

Reboot back to Fastboot using step 9

Do fastboot oem unlock

Select Unlock the Bootloader using volume down and power, your phone will wipe and reboot

On any other variant

Do fastboot oem unlock

Select Unlock the Bootloader, your phone will wipe and reboot

And that's it! Rooting guide will be on post 3.
