FLASH STOCK EMUI RECOVERY info - Huawei P20 Pro Questions & Answers

Hello everyone!
I've got an P20pro rooted with stock Emui (check the screenshot attached). I come from LOS 15.1 but I preferred to go back to the stock, even to get OTA updates. And OTA is arrived but, if I try to update from the Emui, of course, when go to recovery it is go to TWRP and OTA fails.
Is first time I want to flash stock recovery EMUI and I don't know how to do that. I suppose with Fastboot but I can't find a guide, and I'm bit noob... so I ask help from you
In addition to the guide I would also need to get the right Emui recovery version for my device (I don't know if every model need a specific recovery), and I would like to know if when I do flash Emui stock recovery I will loose the root and, I think, the TWRP.
Thanks guys and be patient if my questions may seem silly!

I also need help with this. I have clt-l29 9.0.0.163(c432E5r1P9). Do I need the stock recovery, stock erecovery and stock rom to get the bootloader relocked(locked) and FRP locked again?
If so, how do I do it and where can I get the files that I need?
Hope someone can help with anything they have.

Best option would be use hisuite on pc to go back to full version, power off phone and hold Vol down as connect cable, this should put you in fast boot, repair phone from hisuite, this will flash you back to latest official Fw for your model, you will lose your data.

Installing Firmware on a clean, ROM-Less Device

Apparently, trying to get myself to install a clean rom has ended up on me having no rom at all, only FastBoot access and access to TWRP 2.8.1.0. So. How in this world do i install ANYTHING, when apparently every single ROM version patches over the older versions? where do i find a clean stock rom i can install through TWRP? ( Default recovery throws a cust error ). This is kind of getting insane already.
I hate being this kind of person who registers on a forum just to have some ( possibly incredibly stupid ) problems solved. But here i go.
Since i've heard that there's a lollipop update for Android ( literally 2 days ago ), i decided to start an upgrade. Sadly, it seems like somehow when i installed Se7en ROM, i ****ed something up. After looking around i did manage to find a proper copy of TWRP 2.8.1.0 that i could use for recovery, and after fighting a half brick i had following some of the comments left over here i have gotten back to "normal operation"
The device boots normaly but it seems like it won't do anything on Recovery. The bootloader states it's from version 133 so i am trying to install that as i am writting this. With that said, i see a lot of confusion going on on how to update, and the few threads i find with boot and recovery images, seem to be either dead or get my phone stuck on a bootloop. the custom recovery seems to work but it is not doing any IO operations, apparently. If this is relevant, it seems like the caché partition has been broken somehow. something that would easily be fixed, if it weren't because of the fact it isn't writting or reading.
Is there a way i can safely go to stock from where i am? ( i got an unlocked bootloader, so there is that ), and from there on, how do i safely upgrade to a more modern build? All the mirrors for TWRP2870 seem to crash, returning my phone back to the bootloader. And apparently that is mandatory for an upgrade later on.
I apologize for my lack of knowledge on this.
I apparently have deleted my somewhat working system for nothing. I need to have the stock firmware as a ZIP file for it to be flashed. Does anyone have an idea?
Aaaand now, trying to flash an updated bootloader and recovery i am stuck in what looks like a complete full brick.
Go me.
Flash MyRom 1.2 (http://forum.xda-developers.com/showthread.php?t=2948887) through TWRP. Now you've should got a running system back.
Then flash the emui 2.3 stock Recovery. If you don't find any link the download a B1xx Rom (the last 4 characters of the build-number matters) and extract recovery.img with the huawei update extractor.
After beeing back on stock recocery flash B609 with the normal update-methode. Go on for B621 -> B623 -> B830.
TWRP 2.8.7.0 will work once you updated to at least B609.
I'd been in a comparable situation once again. The correlation of different firmwares/recoverys/custom roms is just confusing when you start dealing with.. So I really can feel with you[emoji14]

Well. i may probably be in trouble since i tried to flash directl ythe B609 bootloader and Recovery from the update.app ( as it looks like 609 is the last known "full" update ), and i can't seem to get back to it. But if i do manage to get enough to flash TWRP again I now know how to get back on track. Right now no matter what buttons do i press, i am stuck at the carrier logo, then it jsut reboots again.
Thank you very much for the reply! i now wish i was patient enough to have waited for this instead of doing a bad flash.
Was there an error or was the B609 Flash successful? Maybe (when you managed to boot into bootloader) flashing TWRP 2.8.1.0 fails now. If so, then try version 2.8.7.0 and use MyRom 3.3.
Did you try connecting your (powered off) device to your PC while pressing volume down permanently? I'm not sure if the phone boots itself now, probably you have to press power, too. Hopefully the phone boots now into bootloader.

Fastboot gave me no failures. it did your typical "sending data .... OK" message. Only remarkable message is that it said that fastboot was informed that the target device only had 800MB ( in bytes ) available for usage. which i fail to recognize as a proper size for any volume that the device could contain.
I could not get into either the recovery or the bootloader, i even tried to press all three buttons and see if i could initiate a update, at least to know if the recovery worked. No luck.
I don't have my phone right now with me since i'm out and i am using an older, backup phone, but i will definetly try once i get back. and give it another try, maybe doing it coldly will make it work.

Reset to stock

Hi guys. I have few questions for you and would be happy and very grateful if you could answer and help me. First of all i have huawei P10 lite which i have bootloader unlocked it, installed twrp and also rooted. I also made backup of the stock rom with twrp. Now i want to restore my phone as new, i mean i want to get back to the stock rom which i made it with recovering but now how can i delete twrp and then lock bootloader? I saw that i have to use img file to delete twrp recovery - The model number is WAS-LX1 and the build number is WAS-LX1C432B124. I wasn't able to find this firmware and i am stuck now. Can i use other firmware for the model number WAS-LX1 or i will brick my phone? How to resolve this issue? I want to get back to stock.. Please help me..
Also is there any way to turn off the warning that says that the bootloader is unlocked and the device can not be trusted or just hide it? I tried to flash logo.bin file but it didn't work for me.
Thanks a lot guys.
Install recovery image from another firmware for WAS-LX1C432.
You can relock bootloader via fastboot using your code and the proper comand. This would get rid-off warning screen. All the info of firmware and oem info must coincide. Otherwise system won't boot unless you unlock the bootloader again.

P10 Bricked after bad TWRP, need help

Hi everyone.
I have a VTR-L09C119 that got bricked after formatting the data partition in TWRP. When I try flashing a debranded FULL-OTA rom I get into a bootloop, and the erecovery won't work (Online recovery won't start, Factory Reset goes into bootloop). And I can't get into TWRP anymore even after flashing it.
I tried putting the VTR-L09C432, VTR-L29C432 and the VTR-L09C605 with the HUAWEI Multi Tool with the Unbrick option, which didn't work.
Any idea how to get out of that mess?
EDIT: Ok I was able to get into TWRP thanks to THIS GUIDE. I'll try a debrand and report back.
I was able to rebrand to VTR-L29C432, the update for VTR-L09C119 doesn't seem available so I don't think I'll be able to get back into my stock rom. For those in the same boat, don't forget to unplug your phone when you want to get into TWRP, that's why I wasn't able to get back into it.

Please help unbrick my phone

I have bricked my phone after Magisk install fail.
I first unlocked bootloader succesfully
then i installed twrp succesfully
then i flashed magisk using twrp - this failed and sent device to erecovery. (which won't find package)
i used twrp to wipe data, now i was able to boot, and it installed like a fresh EMUI. However, almost all apps were broken- could not download themes/camera shut down etc.
To fix this, i wanted to restore to stock and did the following: download update package for my VTR-L09 of EMUI b175 (I was on b162 before), used Huawei Update Extractor to extract files and flashed BOOT.IMG, SYSTEM.IMG and RECOVERY.IMG. This was done without error.
Now my phone won't boot at all. I am stuck at the 'your device can't be trusted' screen. I cannot go into recovery. When I connect via USB, I hear the chime in Windows but I can't seem to connect with ADB.
What to do now?? Am I hard-bricked? I hope that anyone knows how to deal with my phone bricked like this. Please help me to solve this issue.
Best of wishes.
Edit: I am able to enter forced recovery, however updates fail at 5%.
I am also able to fastboot with USB, however I am unsure what to do next.
I unbricked my phone! Many thanks to who ah way and his solution found here: https://forum.xda-developers.com/p10/how-to/guide-unbricking-p10-using-hwota-windows-t3714416
:victory:
why are you doing it when you dont understand it?
You cannot flash part of B175 firmwar eover B162 firmware.. OMG.
use the HWOTa to go back to stock and please stop playing with the device without propper knowledge

Huawei p9 EVA-L09 No fastboot/recovery access.

Hello friends, recently I saw a tutorial on YouTube how to remove the bootloader unlocking notice in Huawei, as a software update arrived for my EVA L09, I wanted to do everything from factory without root or recoverys to install it via ote. So I removed the twrp by the huawei recovery and followed all the steps that the man made and reset the development settings, then I worked in the ADB to re-lock the bootloader, after finishing the processes, my phone was restarted and I'm stuck in the bootloader logo of Huawei, I never step out of there. I wanted to enter the fastbot mode and I can not because it seems to be deleted, I do not know what happens because it does not enter the fastboot mode and only reboots again, nor do I have access to the normal recovery. I tried to use the volume method up + down and power button using the UPDATE.APP but there are no such methods, the phone is apparently clean. it only stays in the logo.
I took him to the technician and he told me to communicate to the support of Huawei because he did not know what to do, I would appreciate too much to help me please, because nowhere do I find something and you are the maximum.
thankfully
Updated thread title and moved to P9 Q&A. Hope this gets you the answers you're looking for.
There are good and proven tutorials here on XDA (XDA has its own search), not sure what did you find and follw from YouTube ( was it for proper cust, proper case of going back from root or custom ROM and which one to stock and which stock build, etc)
To unbrick, you have three options:

- free method but AFAIK it requires Fastboot working

Hello friend, thank you for answering, what I did was the following https://www.youtube.com/watch?v=s9BZuywrRAw I had the original rom of android 7 and I got the update through the B398 ota but I had root and twrp, I wanted to leave everything in the factory by removing the twrp and replacing it with the huawei recovery and removing the root. When it was restarted, it never came back and I do not understand why I do not have a fastboot or recovery mode.
Thank you
It is not enough to say EVA-L09 and b398.
You must know what was exactly your original stock ROM (before you rooted), like was it EVA-L09c432b397 or what.
Then, there is very simple method to go back to the stock ROM you started from, say to c432b397, wherefrom you would then be able to accept OTA to b398...
It's all about flashing the correct HWOTA package through TWRP, and you would be back to your unrooted stock and back to your stock recovery:
https://forum.xda-developers.com/showpost.php?p=74913874&postcount=3
Unfortunately, now after the YouTube, you have no Androud, no TWRP, no fastboot...
Btw, unlocked Bootloader does not prevent OTA updates. It was only neederd to unroot and then to go back to stock recovery - both you simply get just by flashing the right HWOTA package.
Alternatively, you could have to unroot (SuperSU has its own option to remove root, for Magisk there is a ZIP package to uninstall Magisk), and to flash the original stock recovery - and you would be clean to accept OTA (although with Bootloader still unlocked).
