Default [cm-11-20140509-NIGHTLY] can't enter recovery mode any longer

Yuga (Sony Xperia Z) running cm-11-20140509-NIGHTLY

I can't enter recovery mode any longer.

It is impossible both by pressing the power+volume rockers at boot and using the extended power boot menu (reboot->recovery).

The phone simply starts booting cm11.

Do I have to enter fastboot mode and reflash boot.img from newest nightly or is there a different faster way?
