Z3 Dual [D6633] - Don't boot in to recovery

[FallenSp]

Hello guys, I don't have no more idea to fix it.
Today I unlocked my bootloader, all was Stock and no Root. I want try This Lineage OS 15 and is mandatory flash the TWRP to install the Rom.

OK, I unlocked my bootloader and downloaded TWRP Dual Version, extracted the img file from zip and flashed in fastboot mode like the tutorial says: fastboot flash FOTAKernel recovery.img

the flash was donne fine but I can't enter in recovery mode, I tryed in adb adb reboot recovery but isn't work too, anyone have an idea?
Attached some images to explain...

Sorry for my bad english.

Forget, xkeita give me a tip and I can now enter in recovery, I suppose that the Stock kernel don't boot it, just flashed the Kernel rom that I want to use and in sequence, flahsed the TWRP and it worked.

Sumary:
1. I extracted the Boot.img from ROM ZIP and flashed it with: fastboot flash boot boot.img
2. I Extracted the TWRP IMG and flashed it with: fastboot flash FOTAKernel recovery.img

reboot the phone, and turn on pressing vol key down ultil boot in TWRP.

Maybe this is usual to someone.

Thanks a lot @xkeita and @serajr for all the help and suport, I Learned a lot, thanks.
