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

Hi, I need help, I have the Chinesse version of mate 8( NTX AL10), and I installed the 577 version in HiCare, but Im having too many problems and I want to rollback to Android 6.
Someone can show me the way? I tried to install twrp recovery (I have the bootloader unlocked), and I couldnt format data because I couldnt access to internal storage in the recovery.
Thanks

maybe u have to do a factory reset first. if u cant do it with twrp try to enter the stock recovery and do it before flashing. hope that it works this time.
about me, i was on nougat beta, twrp gives me too much errors when i want to format data and system, i installed stock recovery and did a factory reset and i used dload folder, now im on EMUI 4.0 (B180)
dont worry every problem have a solution. good luck
Posted from Mate 8.

Or with Rollback UPDATE.APP.
My Mate 8 is L29C636,i convert to AL 10 with B577 and go Back to L29 C636B211 without any Problem.
I can upload the UPDATE.APP later 92mb.

Use HiSuite via PC and roll back by updating to earlier versions! It's simple

And how did yo do? Can you explain please?

Copy the Rollback UPDATE.APP in dload Folder in Micro SD.
Change oem.info and custom.bin from AL10 to L29.
Boot in Bootloader and Flash Stock Recovery and reboot
This make Automatic a Factory Reset and Lock my Bootloader
Go to dailer and use this code *#*#2846579#*#* and go to 4.Software Upgrade.
After this Procedur copy my Original Firmware for c636B211 in dload Folder and make the same Procedur with *#*#2846579#*#*
After flashing the Firmware i am on L29C636B211
But you have a AL10,i think you flash the Rollback Update App
This Roll Back flash to Emui 4.0 and not to 4.1
After flash the Rollback,Download a Firmware for your AL10 with Emui 4.0 and flash this Update App via dload *#*#2846579#*#* here
This Methode can use with locked bootloader
Download Rollback
I think this works
If not take what was described above

Explain please, is easy when phone isn't Bricked and can enter in "Manufacture Mode"....but with phone only in Fastboot or Recovery how you do?

Get stuck in fastboot after flashing twrp

So I've recently unlocked the bootloader of my global Mi 9T, I want to install twrp recovery but when I flash it my phone gets stuck in fastboot mode. I can't boot into recovery (stock nor twrp) or I'm not able to boot into system. Restored via fastboot rom and attempted it again and still the same thing happened. What am I doing wrong?

PHP:
when flashing twrp I get successful flash but it's not there and I'm stuck in fastboot

i flashed twrp via fastboot and then i click directly vol up and power and i come in twrp.

Flash 4pda davinci-fix recovery by click flashtwrp.bat
It worked for me when i fall in same issue

Hey Guys,
I'm stuck and need help. I've unlocked my phone and installed the PDA4 TWRP. Then I wanted to flash the AndroidParanoid ROM.
Before I could flash it, i had to format data.
Then I sideloaded the zip file via ADB to the phone and restarted
And now all I can do is get into fastboot. When I install TWRP again, the phone hangs at the MI splashscreen.
No clue what to do, as I cannot find a fastboot ROM for my global / europe Mi 9T.
Any help is welcome.

For me, I flashed twrp via fastboot, phone booted directly into fastboot. Even vol+ and power button booted right back to fastboot. I had to restore using fastboot rom

when you flash paosp tou have to flash dtbo.img before reboot to system

@edcedcedc Thank you so much! I didn't find that page through Google. Downloaded the fastboot-rom and flashed it with the Mi-Flash tool.
Then MIUI came up and I coul start from scratch.
Flashing TWRP with the BAT file several times didn't work when I was stuck in fastboot. As soon as MIUI was installed it worked first time I tried.
Again, thank you so much

Ok, Same happened to me But I only have Mac any hint?
I'm downloading the .tgz file stock rom. Is there a way to do this on a MAC?

I got the same.
Have you fixed this problem ?

Hi, Possibly noob question here...
I have successfully unlocked the bootloader on my redmi 9T (mi 9T) and downloaded the corresponding twrp, it flashed successfully and returned the output
Sending 'recovery' (65536 KB) OKAY [ 1.985s]
Writing 'recovery' OKAY [ 0.258s]
Finished. Total time: 2.261s
however, I got stuck on fastboot mode, tried "fastboot reboot" command as well as using hardware keys but it boots into fastboot mode again
how can I get out of the fastboot mode or at least recover the phone to the factory state

Are you talking about Redmi 9T or Mi 9T (aka Redmi K20, davinci) - this is the forum for Mi 9T (not for Redmi 9T)
They are different phones, make sure you flash the correct TWRP (do not flash TWRP for Mi 9T to your Redmi 9T or vice versa)

Yeah sorry, however, I could not possibly get out of the loop so I had to flash stock ROM to be able to use my phone.

You need to wipe data and internal storage after installing TWRP and reboot. Happened to me too.
