No straight up concrete proof, but I have a v10 and v20 also and they finally defeated the dm-verity that begun on Marshmallow, so there may be a way. I am not versed in trial and error rooting, so I couldn't tell you itdefinately is or not. What I can say is not enough people still own or talk about this phone like us, so probably not gonna happen. I may try the old one-root solutions, but I bricked so many times in the beginning and had to send it to LG to fix. I'm not ready to brick it again, so I'm not going to risk it now. The last root on V20 they exploited the LAF partition, so maybe that's the way to go here. Cheers, Johnm
