P9 Lite bricked

Device: VNS-L21 Europe Hello, before brick I was on new emui 5.0 firmware and I installed nougat twrp recovery by user @BadWolfYe and then I flashed this rom: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493 (I was following all instructions) After reboot It was stuck on Phone is booting... And I tried downgrade guide from this thread: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932 I flashed oeminfo zip and dloaded update.app but unfornately zip where I get update.app was corrupted..... Now I have only Huawei eRecovery, dload and fastboot but It doesn't allow installing twrp!!! When I dload UPDATE.APP It says Software install failed. Failed to check the update package. Please download the package again. Please help me!!!!!!
EDIT: I found solution to enter in real recovery(TWRP for nougat)
What I did was:
1. Enter in fastboot
2. connect phone to computer
3. open cmd and type: fastboot -i 0x0fce oem unlock xxxxxxxx (replace xxx with your code)
4. accept fastboot unlock
5. And then it magicaly booted into twrp (my phone's fastboot was unlocked before)
Now I am going to flash back emui 5.0
And then downgrade to emui 4.1
And then I will try to install this: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493
Later I will update this post and I will write does it suceed or fail.
Edit 2:
I flashed emui 5.0 with dload and UPDATE.APP

I wrote an edit how I repaired my phone

hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM. IDK what happened wrong while installing that, my phone got BRICKED. i don't have the Erecovery and twrp either. i cant flash firmware via DLOAD Method. the only thing i have is FASTBOOT mode..
i tried literally everything.. but nothing working..
I sent it to HUAWEI CUSTOMER CARE and they returned it back after a couple of days...
im really very worried because ive been using this phone for like 2 months ... and now im helplesss, If anybody is reading this please help/ assist me out of this..

Huawei p8 lite Bootloop Fix

so i had a p8 lite wich i tried rooting and it got stuck in a bootloop.
this worked for me
WARNING: this does delete everything you have (actually that is already gone)
(read all the way before doing anything)
first i set up adb & fastboot on my pc
https://youtu.be/UN7XW4HnFT8
2nd i downloaded stock firmware from huawei site ( you can also get this from rootjunky)
3rd i used HuaweiUpdateExtractor to get the recovery boot system and cust out (out of UPDATE.APP the one from the firmware)
4th i booted my phone into fastboot (i connected my phone to my pc first because otherwise i couldnt get into fastboot mode)
5th u start the command prompt in the adb&fastboot folder and type these commands (if you dont have custom recovery or custom roms you can skip to 5(i think i didnt do those)) :
1 adb devices (if it doesnt find it wait some time or reconnect it it will pop up sometime)
2 fastboot erase cache
3 fastboot flash boot BOOT.img
4 fastboot flash recovery RECOVERY.img
5 fastboot flash system SYSTEM.img
the system .img is too big so it will go in 6 parts and will often fail but just keep trying make sure to wait long enough because maybe it is still busy
6adb reboot
it should start up now.
these steps worked for me also when i did step 2 i could get into Erecovery wich i could before but now i could erase cache and something else and do a factory reset just press erase on everything then continu

but i dont remember what i did.
i thing i just cleared chache and stuff using adb .
but anyway just keep trying the first few times i loaded them didnt work either

Hi Jan thanx will try it and let you know . Coz currently my device can only go into fastboot and rescue mode nothing else and with commands I can only use fastboot commands ofcoz and not adb commands coz my device is not in debug mode .

Same problem here
i get remote:command not allowed every time i want to use "fastboot flash boot boot.img"
Anyway to fix it ?
