I read that unlocking the boot loader will erase all the settings on the phone. But what if I've already unlocked the boot loader and I run it again, will that erase all settings on the phone or is it smart enough to know that it is already unlocked and it doesn't need to do it again?
The reason why I'm asking is that the root for 4.4.3 is out, and the batch file includes unlocking the boot loader. But since mine is already unlocked, shouldn't it know not to do it a second time and simply ignore it? Or will it erase all the settings anyways?
