[G4 Q&A, Help & Troubleshooting] otavio_aon:
YEs ... i've attached the device on the VirtualBox setting (Settings -> USB -> Add New USB Filter -> LG Eletronic Inc.) but it doesn't look like it got detected by linux (even though LGE Android Phone appeared there... PHOTO ATTACHED)

The Log generated is HERE (I'll paste it below in case it expires).

Also, when I click Show Your Partitions it is empty (but I suppose that is expected as no_device_found is displayed everywhere)

2018-05-26 02:58:53: Your device does <b>not</b> support direct flashing!
Flashing functionality <b>disabled</b>!

Activate flashing functionality by flashing a SALT compatible LAF partition.
Download it right here for <b>any</b> G4 model (requires unlocked device + TWRP):

<a href='https://www.androidfilehost.com/?fid=818070582850495147'>SALT-compatible-LAF_flash-in-twrp.zip</a>

You can still use many of the features SALT offering - just not the flashing part.

PS: Yes, I installed VirtualBox Extension Pack

PS2: I tried to connect my other mobile (an old Sony Xperia) using the same procedure, and I can access it in linux without a problem.
