Did you flash the kernel Included (or recomended) for your rom? because if you are stuck at a sony logo it seems to me that you still have stock kernel.
Edit: it seems that you have just hot boot the first kernel with recovery so when you boot again it just revert to stock Kernel.
That would explain why you can't access to recovery the second time.
You need to really flash the kernel:
1. Turn your phone off
2. Plus the usb Cable in While pressing volume up.
3. "fastboot flash boot boot.img" If you use fastboot in command line or "Select Kernel to Flash" button if you use fastboot in Flashtool.
Edit2: Ok I just realised that you have Locked bootloader so what i just told you won't work. Sorry.
Did you really follow step 10 and 11 and chose "reboot to system"?
The only thing I can think of would be to unlock your bootloader using mihahn thread http://forum.xda-developers.com/show....php?t=1879750
and then install a custom kernel.
