"With the device powered down, hold Volume Down & Power. When the LG logo appears release the buttons and then press them again. Then, press the Power button three times!" (from cyanogenmod wiki) doesn't work for me. I can't seem to figure out how to get to TWRP to restore my phone (currently in a boot loop).
Doesn't connect to adb either because the boot loop stops at LG logo and reboots.
