I have 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 on YouTube, removed the battery, and even downloaded ADB and tried the fastboot reboot command. Nothing worked.

It always shows 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 on how the problem can be solved otherwise?

  • You should now try to flash it

  • 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.

  • 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.

According to this YouTube video, pull out the battery and turn it on again.
