Huawei P10 Plus back to Stock Firmeware / Recovery - Huawei P10 Plus Questions & Answers

Hello everyone,
I have a Vky-l09c432 Huawei P10 Plus with an working System. So I would like to Update the System from Nougat to Oreo, and there is a small problem, which I cannot deal with. So maybe here is someone who has a good tipp for me. The Phone is not rooted, but has the bootloader unlocked.
The Thing is, that I have broken any Recovery installed (There no stock recovery or no TWRP).
So I tried to flash a recovery / System / Boot or whatever via. Fastboot Mode. If I try to do this the command prompt shows up with the fallowing error: failed (remote command not allowed).
All Drivers are installed correctly and in HiSuite the phone shows up too.
So the Debugging Mode is activated, but I cannot active OEM in developer Tools, because its grayed out. And I cannot also relock the bootloader again to use OEM in Developer Option. I don't have the Bootloader Code anymore.
Is it Right, that I cannot flash (failed (remote command not allowed). ) because of the OEM Setting ? (Fastboot devices shows up correctly)
With the Dload Methode, I also have a Problem, because the Files are to great for my SD Card (4GB+).
Is there any Option to install a Recovery (custom or Stock...) on my phone again ?
Kind Regards & Thank you a lot

Zenfone Selfie bootloop / unlock bootloader

Hi everybody
My Zenfone Selfie after a normal update (never modified) is in bootloop.
So I installed adb and fastboot and I flashed the twrp.
Then I tried in every way to flash a rom. I've tried both with official firmware and with various versions of cyanogenmod. Through fastboot and via adb sideload.
Even if seems to work, when I reboot I get the bootloop problem again.
As far as I can understand the problem it’s that I have the bootloader still locked. The official apk solution I guees it’s not applicable in my case. By fastboot oem unlock i get an error message (probably why i can not enable usb debug).
Do you know of other ways to unlock the bootloader or in general to flick my phone?
Thanks to everyone for the help

VNS-L31 Bricked

I messed up.
Flashed LineageOS 14.1,
Forgot to flash gaaps,
Afterward, for some reason could not enter TWRP and in 'Developers Options ' there was no option to OEM Unlock so I could not do 'fastboot flash recovery recovery.img' to regain TWRP.
tried to use the 'dload' method to return to stock 6.0.
message said uptade successful.
The phone now does not boot, does not enter erecovery, does not enter the updater (Power Button+Vol. Up+Vol. Down)
Only thing it does is enter fastboot (it says PHONE Unlocked and FRP Lock).
Can you help me?
Edit 1 : In fastboot mode only commands with fastboot work, no adb.
Because it is a Huawei the command 'fastboot oem unlock' does not work.
Edit 2 :Tried to 'fastboot flash system sistem.img' to flash the system.img from the update.app of stock android, unfortunately with the phone OEM Locked there is very little I can do with fastboot.
If anyone can direct me to a fastboot friendly update.zip that has the android-info.txt that seems to be required for for flashing I would apreciate it. (I have read that you can flash google-signed update.zip's while having OEM Lock)
Edit 3 : Looking through XDA I have found user with a similar issue to mine that have been able to enter recovery update after either letting the batery run dry or using fastboot to erase/format userdata and cache, the result for me is again 'FAILED (remote: Command not allowed)'.
Will be sending the P9 to Huawei and see what they can do with this.
Edit 4 : Huawei replaced the board and the battery (apparently it died during the trip to the repair center) they accepted the warranty despite the fact the phone was stuck on the warning screen that said the phone was unlocked.

OEM unlock toggle is not working

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

i have my huawei p10 plus doing the same thing of yours.....only erecovery mode and when i get to boot in fastboot mode is only fatboot mode & rescue and i had locked bootloader and frp lock.....but i was reading that huawei just block the page to unlock bootloader i just dont know why they did that /......
Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.

(Solved) Please!!! XT1680 Bootloader locked: BOOT UP FAILED

To summarize, I have a Moto G5 Plus, with locked bootloader and I decided to update a ROM STOCK and made a simple mistake by forgetting the OEM unlock option in advance in the configuration menu. An error occurred on the way and tried to return to the stock. Now, when the phone boots up, it enters the boot loader (which is locked) and displays a startup error message that states that you must use the Software Repair Wizard.
trying to enter the recovery gives a code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG "bootmode" configured as fastboot
failed to validate boot image
ERROR: Failed to pass validation, backup to fastboot
Boot up failed
Is there a known solution or force a recovery to work?
Thanks to all
Hello;
I found the solution, download the latest firmware from your cell phone, download it just unzip the zip and look for the files: gpt.bin and bootloader.img, those 2 ctrl + c and files go to the folder where they downloaded ADB tools and paste the files there , then execute the steps to open command window here and execute the following:
fastboot flash partitiongpt.bin
fastboot bootloader bootloader.img
fastboot reboot-bootloader
and it is ready to install the downloaded rom.

Bootloader re-locked and now "System Destroyed" with no solutions

Hi all, I had official MIUI Global 11 on Android 10 on a phone with unlocked bootloader and a recovery. I wanted to re-lock the bootloader, so I went to fastboot and I gave the command to lock it.
Obviously (but I didn't even imagine it) the devide DID lock, but now it doesn't start any longer. ""System destroyed" is the message.
What I want to get is one of these two results: having a working phone OR having everything erased.
What I have already tried is:
- installing a firmware via fastboot: failed because the bootloader is locked
- flashing single .img via fastboot: failed because the bootloader is locked
- erase partitions: failed because the bootloader is locked
- unlock again the phone via fastboot: failed
- unlock again the phone via Mi Unlock: failed because missing authorization in developer options
Let's add the fact that I don't have windows, but Mac, that reduces the available options.
ANY SUGGESTIONS?
You can use Platform tools in windows.As far as i know platform tools can be used both locked and unlocked bootloader.You can search on YouTube how to flash mi phones through platform tools.

I think that the only way to flash it successfully again is to use QPST ,but you need to open the phone remove battery and get 9008 port , check in YouTube.
