    Hey Alpesh, I rooted my Sony Xperia e1 d2005 using towelroot and followed your link here, it says in the service info menu that my bootloader is NOT unlockable, is there a way around that? Does it have anything to do with the method of rooting or is it just happenstance that my phone is not unlockable this way?

    • This means that your device doesn’t support Unlocking Bootloader. Only some device are supported you can check the list of compatible device’s here.

    It says that my model Xperia e1 is able to have its bootloader unlocked on the Sony website, but when I check under rooting status, like it says to do in the prerequisites of this guide it says bootloader unlock allowed:NO. The phone is definitely rooted I followed your other rooting guide for Xperia e1 and have had root access since. Can I safely unlock bootloader anyway?

    • I think you can proceed to unlock Bootloader, but take step wisely and if anything goes wrong don’t blame us. You can check the Sony’s improved method of unlocking Bootloader here.
