So I'm pretty sure I've successfully unlocked my bootloader but as soon as I completed the 12th & last step my phone rebooted, which I thought was normal. When I went to check to see if I had indeed done so I found that when I pull & reinstall the battery the phone immediately starts up without any buttons being pressed. Once the bootloader is unlocked is there now a different way to get into the bootloader since I can no longer do so by holding down the vol down & power buttons?
