P8 Lite 2017 soft-brick (i can use twrp, but bootoop) - P8lite Q&A, Help & Troubleshooting

Hi, I have a PRA-LX1C02, soft bricked.
I have access to the bootloader that is unlocked, I have access to the twrp recovery.
I tried to flash several firmware of these images: Boot.img, system.img, cust.img.
But nothing. I also tried the UPDATE.APP file in dload (both sd and external_sd) but stopped at 5%.
I also tried DC_Phoenix but it did not change anything.
The maximum result I get is: Logo Huawei, Bootloader Unlock Warning, ANDROID and after a while it turns off and reboots in erecovery.
What can I do?

In twrp try to flash supersu then reboot

Hi, thanks for replay.
I flash last supersu and it's the same:
Huawei logo, bootloader unlock warning, android logo, reboot itself, huawei logo, bootloader warning and stop at erecovery huawei...
anythings else?

Flash Stock recovery then do Factory Reset and Wipe cache/Data

With Flash stock recovery, what do you mean?
I flashed a lot of time boot.img, system.img, cust.img.
But the problem still remains
---EDIT---
I flash recovery.img (sorry bad understanding), make a factory reset and wipe chache/data.
But same problem

P9 Lite softbricked

Hey guys!
My Hardware:
Huawei VNS-L21
Windows PC
I've flashed the oeminfo of a Huawei VNS-L31 on my VNS-L21 (followed this guide: http://www.htcmania.com/showpost.php?p=23861935&postcount=2) and after that, I've installed B100 rom via DLOAD-Method. Everything worked fine. Then I wantet to upgrade to Nougat (B336), so I downloaded the ROM and the L31 Data (because I've previously flashed the oeminfo of a VNS-L31, mentioned before). I've done that in the Revolution recovery b. 8. Flashing the main system worked fine, but flashing the data failed. I don't know why (maybe I didn't have enugh patience) but I rebootet anyway. Now I have the problem that I can neither boot to the system nor boot to recovery. However, I am able to access fastboot and I am able to flash recovery, system, cust and boot. I've tried flashing the B336 rom via fastboot (flashing system.img, boot.img, recovery and recovery2 from the extracted firmware and cust.img from the extracted data folder), but I'm still not able to boot. My phone is stuck in the "Your device has been unlocked and can't be trusted" screen as seen in the attachment. I've tried meticulu's twrp and revolution recovery, they also fail to boot (I also get to the "Your device has been unlocked and can't be trusted" screen.)
Hopefully you can help me.
Best regards,

Doesn't work, I've tried that several times
Try to get a recovery running.
So try to flash different recoveries (Meticulus TWRP or Revolution Recovery) with fastboot (fastboot flash recovery *.img)
Flashing N recovery like this *should* work.
Report back then for next steps.

I've tried Revolution recovery and meticulu's TWRP, both don't seem to work. When I try to boot to recovery I do get the "Your device has been unlocked.." screen...

Boot stuck when trying to enter recovery

When i want to enter recovery (by buttons or OTA reason), my phone stucks on Huawei logo. If I normally boot my phone to system it starting without any problems. Fastboot works and i extracted recovery.img from update.app (B596) and flashed it, but this doesn't help.

Try flashing twrp.
Oh... That's was my dying HDD fault. When write sometimes don't working. I noticed that recovery file is form year ago although I overwritten this file with a new one. It didn't worked because i flashed wrong recovery file.

Did I kill my P9 Lite?

Hi there, I'm coming up with the following problem,
I was downgrading my P9 Lite via official downgrade from Huawei.
It was successfull but I am stucking in a boot loop.
It shows the Huawei Logo, vibrates two times and then stays in that mode.
I had an locked bootloader and everything original but when I connected it via fastboot (vol down & power) it says all "unlocked" but I couldn't flash any files (remote: command not allowed), then I unlocked it and flashed the Open Kirin TWRP and fastboot told me it was successfull but I still stucking in boot loop.
As a last try I extracted the Update.app and tried to flash system.img boot.img cust.img recovery.img and recovery2.img which all was successfull but it contains in that boot loop.
How could that be?
I hope someone has a solution, I really need my phone.
Thanks in advance,
UACX64
Reflash the software with the dload methkd.
//EDIT
Managed to fix it and bring it back to life through TWRP.

Device Boot Looping/Soft Brick

I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw
Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.
did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)

Help, fastboot bootloop

A little while ago I downgraded my phone. Today I tried to install magisk with a custom rom and TWRP. It didn't work now when I boot my phone it gets into fastboot I have tried formatting it with TWRP and reinstalling the rom but it doesn't fix it. Are there any solutions (downloading to stock via erecovery doesn't work but I can easily open the erecovery menu.
Fastboot says
Android reboot reason:
bootloader 1
no
NA
reboot_enter_fastboot_common_func
I think there is something wrong with the vendor
Solution:I used the dload trick to download stock firmware
Problem 2:I reinstalled TWRP with a custom rom now my phone keeps restarting and not opening the custom rom.
try this rom
