[Solved] Bricked P9 Lite

Hi, i have a big problem: my phone isn't starting up anymore. Before bricking my device, i was in b160(VNS L-21), then i decided to upgrade to Nougat. So i unlocked bootloader, flashed twrp etc.. Finally i got N working, after that i flashed Revolution twrp and ROM, everything fine. Then i decided to format data, just to get a "clean" ROM, but after this, my phone fell in bootloop and, i don't know why, i couldn't even get into twrp and if i try to boot into it, i just get stuck in the yellow text "Your phone is booting up..." forever. So i downloaded b160, extracted update.app and flashed system, boot, cust and recovery to try to get as stock phone was, but after that i couldn't boot into system: i just saw the yellow choices menu stuck with the same text "Your phone is booting up...", can't even see Huawei's logo. I tried to flash twrp for 6.0, but i couldn't boot into it cause it was replaced everytime by eRecovery. So i tried to install b160 from dload method and it worked but bootloader locked again and i don't have the password anymore, and after Huawei's logo there's just a black screen forever. I heard about some kind of "oeminfo.img" to flash before downgrading from N but i didn't do that cause i couldn't access twrp after formatting data. I tried to install via ota b100, b120, b130 without success, they all say incompatible firmware when i install them. I can just install b160 or b161 but they don't boot up. Please help me if u can, i'll really appreciate it

Try fastboot getvar all . Maybe it contains all the information you need
if not, dc-unlocker will do what you need. I've bricked my device and with their soft I've managed to write the full img. You should try only to unlock the bootloader service from them

You can look at the package of your P9 Lite. There should be a sticker on it with your IMEI.

Thank you! Now i have IMEI and Serial NR, i just need Product ID. Is there a way i can get this?
Edit: I DID IT! YAY! I got bootloader unlocked, i used Huawei Product ID Generator, and typed "HUAWEI Y300-0000" instead of "HUAWEI VNS-L21" in Reformatting Lock Huawei's page, and it worked like a charm! Thank you for your help guys, you're the best

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:

Hello so I'm using Huawei P9 lite
VNS-L21
And after unlocking bootloader I receive this message when I'm rebooting it:
Your device has been unlocked and can't be trusted
How to get rid of it? Because I want to sell this phone..
I really don't know how to relock it so please anyone help me.
P.s I have been flashed TWRP via fastboot..

I'm afraid you can't, the only way is to relock the bootloader

Flash with Dload firmware official lower version you had.
Ex: vns-l21c432b160 + twrp
Dload l21c432b130
Bootloader locked more message.

volume - and power button when phone is off.
open cmd as fastboot and write : fastboot oem relock ;your code;

Flashed wrong oeminfo (L21 on L31) , FRP lock present , dload possible?

Like the title already says, I wrongly flashed the oeminfo of the L21 C432 on my L31 .
Now when I want to rewrite the oeminfo via fastboot I have no access because there is a FRP lock (Bootloader unlocked).
Currently I only see two options:
1. Try to flash a firmware via dload (tried some already, not working) and then flash the original oeminfo again. But is the firmware of a L21 even runnable on the L31?
2. Use DC-Unlock. The question is what should I use there? Is flashing a completely new firmware also overwriting the bad oeminfo? I don´t think so. Or should I remove the FRP lock, flash a new oeminfo and hope that dload is working then?
I hope someone can help me. Such a stupid mistake is just so frustrating, didn´t happen to me in all the years of flashing phones

you can try the dload method using a L21 firmware...

did you ever manage to fix this? I'm stuck in the same loop except my frp is unlocked but my bootloader is locked (Shows in the fastboot white screen mode) I tried to flash via dload method everything from B150 till B380! I was running Nougat rooted and I wanted to downgrade back to MM via flashing oem from twrp but I messed things up!

i cant even dload firstly because i have twrp and 2nd my phone goes stright to erecovery and i cannot find a way to either flash my oem info from twrp back up on my pc or to get new firmware.

A2017G How to relock bootloader on Nougat B10

I came back from LOS 16.0. Flashed A2017G_B10_NOUGAT_FULL_EDL in EDL but there's a warning that my bootloader is locked. I wanted to relock it but the warning prevents me from entering bootloader or fastboot (or maybe they are not even present....). Next I flashed A2017U_FASTBOOT_UNLOCK_EDL in MiFlash but it did not do anything. It flashed OK but I still cannot access fastboot. Should I flash some marshmallow rom? Thanks in advance.

I have the same problem. Cannot enter fastboot mode on Nougat ROM.

Ok I found the way usin Axon 7 Toolkit
1. Set the Android version to 7 using option 13
2. Perform unlock bootloader
Following instruction Axon & Tookit gives you EDL image of the proper fastboot partition giving the possibility to enter fastboot mode
then fasboot oem lock

I wanted to say thanks that works, but apparently my phone is bricked now - it hangs on green ZTE logo. PC recognizes it as DFU. Cannot enter EDL either. I guess I look for some guide how to recover from this situation
Managed to fix that. Somehow I was able to enter fastboot. It said my bootloader was locked so i flashed TWRP and from TWRP using ADB installed stock Nougat rom

If you was able flash twrp mens your boolaeder was unlocked?

No there's a TWRP that works on locked bootloader.

Seems that TWRP was inatlled before the bootloder was locked again.
