Cannot boot to bootloader, fastboot or recovery I have Sony Xperia Z2 with Cyanogenmod 1220150305

I cannot boot into any recovery based applications.

I have tried with the phone off and the down and up volume buttons, I have tried with apps that reboot to recovery, I have tried with the advanced power button on CM, I have tried with adb reboot bootloader/recovery and I have tried by just trying to install an update from the CM Updater.

What do I do to get this into Recovery? Otherwise the phone is fine, but it now means I can never update the phone ever again which I am not happy about as this version of CM12 is not great.
Turn off your phone and let it stay like that for 20 seconds
Then try the key combination again until the led goes blue (from pink)

If that doesn't works
Try flashing the cwm recovery image again manually using 

fastboot flash recovery nameOfTheImage


Or follow this link to download the boot.img file and flashing it via

fastboot flash boot boot.img
