I'm getting a bit confused. I do have a unlocked bootloader (Sony Z3c) and after reading through the important posts, i thought it would be possible to get the Recovery by flashing the Nut's Kernel. I used fastboot to do that (fastboot flash boot boot.img, which i extracted from Nut's flashable kernel zip). I tried with official stock firmware and with a prerooted alternative (Lollipop). With both of them i was not able to boot to Recory. Can anyone provide me some help with that or let me know if this is not possible even though Nut mentioned this in his "famous" post #3703
Thanks a lot!
