Fastboot: When I hold vol up and plug in the usb cable the phone says "download mode do not unplug the usb cable until the update is complete" and it says 0% at a progress bar which never changes Holding volume down which plugging in the cable has no effect the phone just charges while powered off
ADB: I don't know how to use ADB to unlock the bootloader I found some instructions for it but the instructions said to type su inside the adb shell and that got me a permission denied error
