Ah, that's strange then! I'm running the same version of Magisk as you are.

Any ideas what could be causing the issue?

EDIT: Just checked my build version and might have flashed an incorrect firmware!

I used Firmware Finder and downloaded CLT-L09C432E5R1P9B163 The first bit matches and I assumed the last bit was EMUI 9 stuff. The download came down as update_full_CLT-L09_hw_eu.zip

Build number now shows CLT-LGRP2-OVS 9.0.0.163

Searching for LGRP2 leaves me at a loss to what it is
[Huawei P20 Guides, News, & Discussion] otonieru:
Did you update using HuRU ? if yes, it just the flashing process failed to flash some of the partitions (most of the times, /vendor /cust /products and /odm were failed to be flashed). Previously I also face same issue with you, build number incorrect after flashing,

i suggest reflash it using Re-flash 9.0 tools from the same HuRU thread
[Huawei P20 Guides, News, & Discussion] mushtafa:
Yes, used HuRu, and yes there were errors in the log after flashing about mounting certain bits.

Not heard of Re-flash, I'll take a look.
[Huawei P20 Guides, News, & Discussion] elhana:
Maybe you flashed beta rom, then safetynet will fail due to beta device fingerprint.

I bought the P20 Pro with Android 8.1...I unlocked the bootloader, I updated it to Android 9 (Pie) and now my OEM Unlock under Developer settings is grayed out. There is no way to toggle it ON/OFF. I suggest you unlock the bootloader first then update to Android 9...it's safer this way to enable OEM Unlock. As per the bootloader unlock...use the paid service because it is the only way to obtain the bootloader code. Hope it helps and good luck.

if you need recovery, flash it temporarily from adb

what he remapped is the reboot button on magisk manager if i recall correctly,

[Huawei P20 Guides, News, & Discussion] ndv92:
Yes, the pre_patched recovery_ramdisk in this thread use an old Magisk version that required holding Vol+.

You can just download latest canary Magisk and flash with Magisk also. You should install latest canary Magisk manager apk also.

newly released / uncertified rom version are common to get a SN failing because that version of rom might havent been submitted to google.

it also happen on some of previous oreo firmware. (.150 and .130 if am not mistaken)

how to avoid it ? dont update too soon. or try other available version

What should the patched twrp do?

Could someone explain why we can't flash the patched boot image to kernel partition?
[Huawei P20 Guides, News, & Discussion] otonieru:
EMUI 9 implement system as root, there's no longer kernel ramdisk partition,

we are lucky topjohnwu found the work around. which is, using recovery ramdisk partition. This way, we gain root. But no custom recovery. Its either root or recovery. You cant choose. At least for now.

and you never recommended to use patched twrp image to begin with, topjohnwu himself recommend to use patched stock recovery ramdisk image.
[Huawei P20 Guides, News, & Discussion] curtricias:
Yep had that also. Now on .197 and safety passes again ?

---------- Post added at 09:40 PM ---------- Previous post was at 09:31 PM ----------

Why for God sake use twrp?

Extract recovery_ramdisk from update.app and place somewhere on SD card.

Install Magisk 18 manager.

Manually change the update canal to : https://bit.ly/2MPKGY5

Press instal magisk l. Use the patch boot IMG option.

Direct to your recovery_ramdisk.

When the patch is done copy the patched_boot.img to a folder on your computer.

Reboot to bootloader

When in bootloader: fastboot flash recovery_ramdisk patched_boot.img

Fastboot reboot

When boot press vol up. Bootlogo will appear and you'll have a rooted emui 9!

No rooting method working

Strange,

tried different rooting methods like

- Sideload in TWRP

- Patching TWRP

- Patching Ramdisk

- Pre Patched Ramdisk

but non of these worked!!!

I always stuck, Phone displays: Devie is booting....

Model is CLT-L29 (C432E5R1P9)

If someone has an idea how to get it rooted, i would really be thankful!
[Huawei P20 Guides, News, & Discussion] otonieru:
explain your exact steps.

sideload wont work. thats not the way to root this phone.

did you patch the ramdisk using canary magisk ?

how did you flash the patched ramdisk ?

if you didnt press vol up during boot, does it still boot to unrooted system ?
[Huawei P20 Guides, News, & Discussion] Lagg4free:
OK, here are the steps I did:

- upload recovery_ramdisk to phone

- patch that file with magisk manager and canary build 18.1

- download flashed image

- ADB reboot recovery

- fastboot flash.....

- fastboot reboot

And

FREEZE!!

Also tried with twrp image, and the prepatched one also!

Found in a German forum a way via sideload,

But none of these worked for me!

Funny thing beside, no difference if I lock or unlock OEM in developer settings.

So I really don't know how to get it boot via the recovery trick.

And if I boot normal there is no root.

Thanks

[Huawei P20 Guides, News, & Discussion] doktor29:
you need to reboot to fastboot not recovery,

and you need to hold vol up button on every boot to start system with root

i make root on .160 .195 .197 and always work, so you doing something wrong

[Huawei P20 Guides, News, & Discussion] doktor29:
hard to tell what you are doing wrong.

i always set usb debuging, then install latest magisk manager app, set custom update channel to: https://raw.githubusercontent.com/topjohnwu/magisk_files/master/canary_builds/release.json

then press install magisk, patch boot image from your system version (recovery_ramdis - without "k" on end), then reboot to fastboot and fastboot flash recovery_ramdisk "pathed_file" (without " ")

fastboot reboot and directly hold vol up button and should work.

Doktor29 tells you to boot to fastboot and you reply that you boot to bootloader and not to recovery. This shows that you two are not ¨on the same level¨, so to speak. Actually, fastboot & bootlader is the same

What are you guys using to backup your partitions nowadays? Since we don¨t have TWRP readily installed.

I presume I have to do this when I want to make a nandroid backup:

- replace patched boot image in recovery_ramdisk by TWRP image

- make backup in TWRP

- reflash patched boot image into recovey_ramdisk

Can you confirm? Or else can you advise some app that can to this nandroid backup?

What I seriously miss from Back in the Days when "Smart devices" where new is the Willingness to help.

To state "you will need to go back to stock" is most definitely correct, but the real question is of course How.

The How is where you would shine.

I don't know this, because of the extreme changes in the OEM:s handling of bootloader, recovery and startup policies implemented nowadays. From the ZTE Blade, HTC HD Blackstone, LG G2-days and up til Nexus 6P I knew it all. But with this P20 it's all complex and intricate. :cool:

The naming of firmware have been changed month back btw, its no longer showing L09 or L29 etc, it simply show EML (for emily), CLT (charlotte), and so on, continue with LGRP2 OVS

so its not that it doesnt match your device, it just the name that changing to become more universal across model region and variant
