Answer 1

I found my solution from this similar thread by enabling USB tethering on my LG G6 (requires data saver to be turned off)

Go to: Settings -> Tethering & networks -> switch on USB tethering

Answer 2

It depends on windows system but usually:

1. you go to system properties
2. look at hardware devices
3. Right click on the yellow (has to be yellow if it's driver problem) icon representing your mobile device
4. select property
5. Then go on the driver tab
6. select update driver
7. choose the bottom selection find on local computer
8. then choose manually
9. From the windows opened look for driver disk the bottom right button
10. Choose the driver from the folder <sdk>\extras\google\usb_driver\i386 (or amd64 for and).
11. Remember to uncheck the show only compatible hardware.
12. Then choose the driver
13. When windows warn your about possible incompatibility go on.

For my mobile it works, but depend on your mobile if it work or not.

Hope this help, bye.

Answer 6

Just wanted to provide a simple answer here. I am just messing with an old Android device for the first time doing these root and unlock procedures. I received an error like this one when an adb push "..." "/sdcard/" command failed, and the key was that my device was in the bootloader screen. Booting to recovery then allowed me copy over the file(s), and I presume the normal OS would as well.
