I managed to root V10d (D325).
Few important things:
- only way is via "recovery"
- only way to recovery is via adb
- make sure adb is from kitkat and lg usb drivers are installed
- make sure you formated microsd card to ext2
- find update.zip (google it) and copy to sdcard
- adb shell, then "reboot recovery"
- flash update.zip, reboot
- install xposed framework and remap touch buttons
