Default Rooting Problems on the C1904/C1905

Hello.
I recently tried to root my device.
I followed the official Sony guide to unlocking the bootloader, but, as soon as I booted the device it became stuck on the boot animation.
I flashed it back to the factory settings, firmware 15.4.A.0.23. Retried the procedure, same results.
Re-flashed it to 15.4.A.0.23, and installed CWM after attempting the bootloader unlock (again). It was stuck on the boot animation as it was before, but I could boot into the CWM. With it, I managed to use the SuperSu.zip update, but I still get stuck on the animation.
Am I doing something wrong?

Nevermind, managed to fix it. Downgraded to the previous firmware and used Framaroot.apk.
