I know I can try this method and see what happens and then report back if needed, but I don't think that this is a thing safe enough to test, so I'll ask before I try: is this for any LG G6 version? Does it work on the H870S (Dual SIMs version)?
P.S: I don't think that this version even has the possibility to unlock the bootloader
Also, isn't a phone that has an unlockable bootloader also rootable?

Only for H870, H872 & US997

By saying H870, that means any H870 (like one from Central America) or just the same EU H870 that is listed on the LG Developers page?

Does this wipe the phone?

Does this wipe the phone?

Fastboot OEM Unlock will Factory Reset the Phone

Only for H870, H872 & US997

Will this work on T-Mobile version of LG G6(H872 TM)? Are you sure it will not do any damage to the phone like hard brick?

This does not work on H872 period.
You will get
writing 'boot'...
FAILED (remote: unknown command)

Does this work on the H871?

Could you tell me how did you get the boot.img file? @leonlelion
--Edit--
Nevermind I found it and rooted my device (H870-V30B-EUR) succesfully. If anyone needs it it's inside the ZIP file: https://forum.xda-developers.com/lg-g6/development/rom-lg-h870-eu-30b-rom-t4007979

The simplest, best method!

The simplest, best method! The boot.img I got it from this archive: https://drive.google.com/file/d/1Xxoa2KdcoPTPriZL1IZh056J9rQ7NFiV/view?usp=sharing . My phone: H870 with V30b.

Does this work with H872?

 

[xGiox]

I am interested if this will work on my h870s since i am one of the lucky ones who got 'official' bootloader unlock key, and my bootloader is unlocked now. And if it does when i flash this will i be able to safely modify system files.

 

[amazi09]

Thanks a lot! root easy and fast, I used the boot.img file above, fortunately I had an unlocked bootloader

 

[Keron Cyst]

Would anyone know where to find the boot.img for the US997?

 

[surfshark]

Do you have a modem i could just flash with this h873?
