[LG G6 Guides, News, & Discussion] sybreeder:
I've Managed to successfully updated phone using Method from 1st post.

I have H870 but now LGup recognize it as AS993 and it dosn't want to update KDZ from H870

Further more there is some kind of Password that i don't know - LG Secure Startup. I can't pass that.

What more can i do ?

I used method with test connection inside phone - it was bricked and there was black screen after boot logo.

It doesn't want to go to fastboot.

Any suggestions ? Anyone know what that password is ?
