i flash stock recovery.img of my current version ?

You can try this.
https://www.guidebeats.com/2016/11/26/downgrade-huawei-p9-nougat-marshmallow/

You have to flash the stock recovery for b361, and then relock the bl. You can achieve only the relocked state. To official, locked bl, you have to roll back to b182, or any other marshmallow rom, and then update to nougat.

did you unlock the bootloader and root? Its not a problem with TWRP. Since you have received the OTA sounds like you didn't do any of the requirements to install TWRP. I would do some research on Unlock Bootloader, ROOT.

Bootloader Unlock , Phone Rooted.
I downloaded the OTA but when is going to be recovery mode TWRP Not allowed to install it.
That's why i need Stock recovery or update file that we can flash from TWRP.

TWRP isn't going to let you install the OTA file. You need to update your firmware. Flash lastest TWRP in Hboot or fastboot. I would read this thread here.

To upgrade you need to flash lastest firmware then ROM of your choice. To make that happen you need updated TWRP. The ruu is your OS and firmware, you better care.

Please provide more information - is the ROM the stock one? Did you flash a recovery? Did you flash a bootloader? Is the bootloader locked or unlocked?

Most Probably Flashed Wrong Boot or Recovery img ... or used some other rom ..... Like L05/L07 rom on L00
I flashed [ROM] Se7en-Rom v3.8 / EMUI 3.0 / 4.4.2 / B602. after I flashed CWM flashable from recovery B609 for P7-L10 .after I wanted to go back and have left the mess .from fastboot I flashed all boot and recovery possibile but nothing. continuing to turn back with Huawei logo or just in fastboot

Flash the recovery from here. This is the official recovery for B609.
After that, download B609 full official ROM, and put it on the SD card in a folder called dload. (Note: the file is probably zipped - the only thing you need is a file called update.app.)Start the device by holding all three buttons. Force update should commence and you should get a usable, fresh official B609.
i tryed to do what did you said but it didn't work
thank you anyway
I tried everything you guys .According you can run again? bootloader and unlocked I have done everything with PC bootloader. but with the usual commands (flash boot, recovery.system.cust.userdata) caisson other commands that you can do? you can say if you can restore or abandon so?
Did you try to flash cwm 2.8.1.0 then flash MyROM 3.3, then flash full version B609?

How to install stock recovery/rom/unroot/relock bootloader?

Guys , I have to sell my phone, so, I decided to do all the necessary to have it stock..
So, the question is, how can I do this? I need the phone like when I bought it
You can do most of this via SRK Tool. If you can't relock bootloader then you can flash your stock update.app via stock recovery and that will relock your bootloader and get rid of root.
Please don't follow this for when you have Nougat beta installed though.
I currently have TWRP recovery.. How can I put stock recovery?
Is better to put 1st the rom and for 2nd the recovery or contrary?
Anyway thanks for answering me!
1. Backup (as always)
2. Flash stock recovery with flashify for example
https://www.androidfilehost.com/?fid=529152257862669572
3. Flash stock Rom b182 with dload-method
http://download-c.huawei.com/download/downloadCenter?downloadId=91783&version=358257&siteCode=de
Now your Bootloader is relocked and everything is stock again (I hope so)

To go back to Stock EMUI

Is is possible to flash the EMUI zip update file by TWRP to get back to the stock ROM?

Nope, that is not possible through TWRP. You have to flash a stock recovery first and then use three button method to update...
official way is dload way . use it to go stock !

Flash stock recovery in fastboot first.
If you have kirin 620 version, I guess you could use updateflasher.zip to flash UPDATE.APP with TWRP recovery. Check this thread http://forum.xda-developers.com/honor-4x/how-to/install-emui-4-1-4x-4c-g-play-g-play-t3515702

Flash stock recovery via fadtboot.then flash stock ROM via dload method

you need to return to marshmallow firmware probably its B136 for you.
1.Flash Rollback Package via dload.
2.Flash B136 firmware via dload.
3.Boot up your phone an check if FRP status is LOCKED. (It need to stay locked)
4.Update to B182 via OTA.
5.Update to Nougat via ota or via dload.
6.Unlock Bootloader
7.Install TWRP https://forum.xda-developers.com/p9/development/twrp-t3565703
8.Flash SuperUser https://forum.xda-developers.com/p9/development/root-supersu-2-81-emui-5-t3612258
Basically its this guide: https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
But this guide will change your OEMINFO (debrand to EU version C432) but this is not bad for future updates.
But this guide is for EVA-L09.
