Well I m not sure about what I am advising
My friend can boot into recovery using home button for sure, maybe it depends on kernel (or the recovery version) too. So why not flash a different kernel (which includes recovery :: almost all custom kernels have that, not the stock one) using fastboot mode and then give it a try.
I also found the following command
fastboot reboot -bootloader
although it didn't worked on my xperia Ray (assuming bootloader here refers booting into recovery)
