How to enter in TWRP/recover on Huawei P9 lite with keys?

Question

I have a p9 lite Huawei.
I can boot into twrp with this command 



adb reboot recovery


But without adb, I cannot enter in recovery mode.
If I push Volume Down+Power, it goes into bootloader (I can see a green droid logo).
If I push Volume Up+Power, it opens the EMUI recovery.

I have installed the twrp with



fastboot flash recovery twrp.img
