Yes

1. Crossflash to G710ULM11g_01_NAO_US_OP_1112.kdz

2. Reboot enable debugging in developer options.

3. Turn off device disconnect usb cable then hold volume down while you plug in usb cable again then you will boot into fastboot.

4. Enter this at the command prompt: fastboot oem lock and then enter fastboot reboot. You are now bootloader unlocked. Crossflash back to your stock kdz.

If your bootloader detects anny signs of wrong software it won't boot and you are Bricked
