HOWTO: Find Out If Bootloader Locked

1. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
2. Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
