Unable to unlock the bootloader on 4.3
unknown error occurred , which may be a network error please try later
This annoying sh1t occurs when I try to unlock the device with the official unlock tool for 4.2.
Actually what I want is just to root it, but currently it's no way out but unlock it to flash in the root.
How am I supposed to deal with it? I can't bear using an unrooted device.
Thanks for any help. Though I know most of your solutions won't work.
