(help) my phone stated "your device has failed verification..." on boot.

Build number DUK-L09C636 now im in emui 8.0 beta, the problem happened when I wanna rollback to emui 5.0 using Firmware Finder. Help???

Bro, you won't be able to rollback to nougat until the official version is rolled out to the users. My device is C675 and I installed the Beta version as well but I couldn't get back to Nougat in spite of trying like 1000 times and spending almost 3 days on Google and XDA. I tried almost all the methods available there. Not to disappoint you but I'm waiting for the official Oreo version to be rolled out so that I can flash the same and do have a complete working device.
Cheers!!!

thanks for the answer!

Hurmmm just curious is oreo beta for honor any good? Any bugs or not working things? Why u guys want to rollback to nougat? Whats the obvious improvement? My wife owns Mate 9, the official oreo update was good and faster than nougat, but sadly there is no Huawei Histen (equalizer and bass settings for audio) in it which mate 10 series has.

The differences between Android 9 and Android 10

I recently brought Rmn8p with miui 11.0.6 (global) , wait to unlock bootloader. After that flash preloader & lk then trwp and root.
I was wondering what's the difference between android 9 and android 10? Is it almost the same like I read at some post? Someone has updated to android 10 may share some viewpoints with us, thanks!
Already unlocked bootloader , root and xposed , phone recorder installed. Thanks to those pioneers.

Hey. I think this is widely discussed elsewhere. Just search for "MIUI Android 9 vs MIUI Android 10" in Google or YouTube. You'll find way more information there than you would ever find here regarding such generic topics. Have fun ?

Help me to root my phone

I am using p20 lite model ANE-AL00
EMUI version: 9.1.0
Can anyone suggest me a working bootloader unlock method.
Now even the huawei support are also now giving the code even if we pay.
I tried many ways but only ended up with 10 tabs open on my browser and a bootloader locked phone.
Help me me out.

C636E5R2P3 version stuck at 10.0.0.196 (EMUI 10.0.0) Security Patch June 2020

I can't get my Mate 20X to upgrade to EMUI 11 - I tried downloading:
Build: EVR-LGRP2-OVS 11.0.0.155 - update with full base
from this site: http://huawei-update.com/device-list/evr-l29
I tried all three variants of this build since they weren't labelled for which variant of the phone (mine's the C636 variant). When I tried to apply the update via the memory card all three times I got "No file found" even though UPDATE.APP file was in the root of the memory card where it should be.
I also installed a VPN, set region to UK in the Huawei Support app and in the VPN software and then tried the update OTA and nothing. Set region to China for both and still nothing.
Of course, the reason I'm doing this is to get EMUI 11 with the July 2021 security patches. My build is over a year out of date. I'd even consider going from EMUI 11 to Harmony OS but again I can't get off the July 2020 build currently installed.
I've tried going with other, newer Android phones, many of them the very best available. I've gone through:
- Samsung Galaxy Note 20
- Samsung Galaxy Ultra S21
- Oppo Find X3 Pro
- Xiaomi Black Shark 3 Pro
- Lenovo Legend
- LG V60 dual-screen
Despite liking some of these NONE of them give you the screen real estate that the Mate 20X does so I wind up dusting it off, updating all the apps and using it once again!
Can someone please help me figure out how to update the software on this beast??
Thanks, in advance for any and all comments!!

I am stuck with the issue. I am trying Ministry of Solutions, guy to help me out. He changed my Chinese one to global one.

Black Shark 3 does have the same screen real estate, with higher resolution and the 90 Hertz refresh rate, but it's SO HEAVY.
EMUI 11:
I also have the mate 20x and I've tried everything to update this. I changed the regions and I used the VPN and I tried rolling back to Android 9 via hi suite..... nothing. Someone recommended I spend 15 bucks on a Chinese SIM card from Amazon and that's exactly what I intend to do tomorrow.
Please let me know if you're able to update your phone! I just replaced the battery with a brand new one and spent way too much money on the Huawei branded storage media... I tried a bunch of different phones but I really want to keep this one!
I find it amazing but even phones with side-mounted fingerprint readers don't allow you to do the swipe option for notifications the way Huawei lets you do it. I like my infrared blaster, too. Sigh.

Android 8.1 to 9

I have a Samsung J2 SM-S260DL still stuck on Android 8.1. Some of the apps I use are now only compatible with Android 9 +. Does Samsung automatically update the phone's Android ---because I contacted Tracfone and they told me it's up to the phone manufacturer. I tried the phone's software update, but don't get the 9 update.

What firmware version is currently on your device? You will find the info in the settings about the phone.

Android 8.1.0_0008
Build MTAJQ.S260DLUDU2ASE4
Kernel 3.18.14-16126611

I don't think Samsung after 4 years of releasing this phone has the motivation to improve Android 8.1 Oreo (Go edition) to version 9. Enjoy what you have.
p.s.
What compels you to look for android 9?

B/c a few of the apps I use are now only compatible with android 9+. I've only had the phone a couple of years--I got it from QVC. They tend to sell phones already released for cheap. I got the Samsung J2, 1500 data, 1500 texts, 1500 minutes with 1 year of service for 59.99 --on 6 payments of like 10 bucks. Phone works great. Is in excellent condition---but just need Android 9 b/c some of the app updates need newer versions of android
