I have the LG G5 for about a year now. Today, my phone get into fastboot mode, I haven't done anything. Now, I tried all the tutorials in youtube, and removed battery, even downloaded ADB and tried the fastboot reboot command. Nothing worked.

It always show the same message:

Welcome to Fastboot Mode for bootloader unlock:

Please check 'Enable OEM unlock' in Developer options

Quick Guidance

1) Read Device ID fastboot oem device-id

2) Write Unlock Key fastboot flash unlock unlock.bin

3) Check bootloader is unlocked fastboot gevtar unlocked

How to exit fastboot mode

1) Press the Power button for 10 secs to turn off the device

2) Use 'fastboot reboot' command if the fastboot is available

I tried the HOW TO exit already. Even talked to the LG Service, they told me to send it to them. Any Ideas how the problem can be solved otherwise ?

  • You should now try to flash it – esQmo_ Jul 4 '17 at 13:22
  • 1. Install ADB, if you haven't already. You can Google it or find instructions at this link: xda-developers.com/install-adb-windows-macos-linux 2. Once it's installed, open a command prompt and navigate to the directory where the executables were installed (for me, it's C:\adb). 3. Type 'fastboot reboot' (minus the quotes). That should be all there is to it. Hope by now, almost three months later, you've already found a solution, but posting anyway in case someone else has the same question. – B.Rossow Sep 26 '17 at 19:12
  • The Problem is, I don't know anything about flashing at all. And I already tried it with ADB too. It really don't work. I sent it to LG but they wanted over 290 € for repairing it! I don't have the money for something that expensive. – Sebnem Sep 28 '17 at 14:02
