    Hello,

    So I managed to unlock the bootloader on my E5506 and flashed a Marshmallow .ftf, then repaired the device with Xperia Companion . Now when I try to re-unlock, I fail. I even rolled back to Lollipop with everything and still can't get out of this thing. Does anybody know how can it be fixed?

    Thanks.
