can't connect to wifi using lineage os LG g3s (jagnm) i recently updated lineage os to 14.1-20171206 on my LG g3s (jagnm) and there are several issues:

1) can't connect to wifi. Apparently it's because wifi mac address got switched to all zeroes (00:00:00:00:00:00) i found somewhere that ifconfig wlan0 down should fix this but it doesn't work, mac stays the same.

another possible solution i found was this https://forum.xda-developers.com/showpost.php?p=70109272&amp;postcount=5

in short:

Make an img of dev/block/bootdevice/by-name/misc
Edit it in a hex editor (details in the link)
Overwrite misc with the img
Reboot


there is just one 'small' problem: dev/block/bootdevice folder doesn't even exist. 
I'm at my wits end. I would appreciate any help.

2) another small problem: for some reason if i connect my device to pc or my laptop and choose on the device to use usb to transfer files it almost instantly makes my computer to crash into BSOD.

stop code: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
what failed: lgandnetmodem64.sys

PS: if it's not obvious already i'm a complete noob at command line and shell

EDIT: installed 6.0.1 resurrection rom. The mac issue persists.

ALso the PC crashing got worse. With lineage at least i could connect to adb, but now if debugging is enabled pc crashes instantly when i plug in the usb. 
Even though i have very little experience with stuff like this i can guess that the issue is deeper than the rom itself. Also something might be bad with LG usb drivers
Root your phone, install Mac Changer from Here and solve that issue ASAP
