How to unlock LG G5 (H850 Europe) Bootloader:

To enable USB-Debugging, go to Settings >> About phone >> Software info and tap Build number 7 times. Return to the previous screen, select Developer options and enable USB-Debugging.
Step 2. Enable OEM unlock on your phone. Activating the “Enable OEM unlock” is necessary for the bootloader unlock. To enable OEM unlock, go to “Settings >> Developer options” and check Enable OEM unlock.
Step 3. Store your device’s IMEI code in Notepad. You can view the IMEI number by entering *#06# on your phone or selecting the Settings >> About phone >> Status >> IMEI menu.

Step 4. Connect your device to your PC. To reboot your LG G5 in bootloader mode, type the below command in the black window:
adb reboot bootloader
Step 5. Once in the bootloader, use the following fastboot command to obtain Device ID:
fastboot oem device-id
This fastboot command will return a character string. This is the Device ID which is needed to generate your unique unlock key.

fastboot flash unlock unlock.bin
Step 9. Once done, confirm the bootloader’s lock status by using the command below. As usual, copy paste it, or type manually if you have become fond of fastboot by now.
fastboot getvar unlocked
