[Q] ADB Device Unauthorized - No Solutions Provided Worked

Hello fellow xda-members,

my ADB isn't working anymore. I own an LG G4 H815 Intl and a windows 10 computer. When I bought the G4 and rooted it ADB worked without a hassle.

Now, 6 months later, ADB is gone. I tried

• 
  

  Code:

  
  

  ---

  adb kill-server

  ---

  
  
  
  

  Code:

  
  

  ---

  adb start-server

  ---

  
  
  and replugged the cable

• Installed latest LG Drivers

• Reboot phone and PC

• copied adb_key.pub to the phone (/data/misc/adb)


• erased .android. folder on PC (/C://User/me/.android.)

None of that worked for me and I feel like the internet offers no more solutions for my problem. Been on, like, 20 pages.

So if anybody of you faces the same problems - please help :crying:
