Chinese version Mate 9 with L29 (European) B156 installed, how to update to B156?

Ello Ello,
I imported a Chinese Mate 9 with L29 installed on it by the seller, I assume via FunkyHuawei.
I'm encountering the touchscreen lag glitch, as well as the lock screen notification problem, and would like to upgrade to the newly released L29 B156.
Since I already have L29 base firmware installed on this Chinese model, can I update using the instructions on gizrom?
Or will this brick my phone?
I depend on this phone as my lifeline so I can't afford to brick it, thus my asking right now.
Should I use FunkyHuawei instead?
Thanks
-Seb

Any suggestions?

Downgrade from 11 to 10 for install GMS (HELP)

Hello guys. I have a mate 30 pro 4g EU version. LIO-L29
EMUI version - 11.0.0.188
I wanna downgrade to 10. Because i wanna install GMS. I have succes downgrade last 2 week on p40 pro.
Now i try first to downgrade first from Hisuite. I have install Hisuite_10.1.0.550, but i dont have the button switch to other version.
if i try to HiSuite Proxy, i recive error:
[15:48:06]: Connection To HISuite Proxy Failed....
[15:48:07]: Check If Your Firewall Is Blocking HISuite's Proxy Server
i have add the app to the firewall, i have stopped the firewall...same
Please help me to figure out.

Hey man. I'm in the same boat. Unfortunately, I don't think we are able to downgrade to a lower version. So, we are stuck without Google. The only negative of not having GMS is the delay or no notifications coming in at all. Hopefully apps will be updated to work well with HUAWEI notification eco system.

Hey bro. I have succed to make it

ช่วยบอกวิธีทำหน่อย thank you

Hey, can you share with us how you downgraded from 11.0.0.188. Thank you.

With hisuite proxy

Thanks. Which firmware version you downgraded to?

Well, after multiple attempts using different firmware versions, the update fails after it has reached the 100% download. Have no clue what else to do. Firewalls are off, antivirus off. Anybody?

I followed this guide: Make sure those selections matches your phones need (region, etc..). If they don't match,..you know what might happen.
Complete Guide
Modifying HiSuite and manipulating it's connection data to install Roms before they officially get released. - ProfessorJTJ/HISuite-Proxy
github.com
BUT like I mentioned at a different thread. If downgrading to 10, Googlefier Wouldn't work. Also, I had lost USB connection and fast/super charge. But I think downgrading to a lower 11 should be ok. But I don't know. If you loose that, just upgrade again.

@robjbw thanks for answering. It will help everyone.

Stuck on 11.0.0.196 and can't downgrade

Hello,
I was hoping someone could help.
I have a P40 Pro (ELX-nX9) which was running GMS fine from May 2020 until last week when it got sent off for a new screen, complete rest.
I have since spent almost a week following all the guides to try and download the firmware so I can use Googlefier to get GMS.
nothing works, always "update failed". Tried using the HiSuite Proxy to roll back to even an earlier version of 11.0.0.x but same issue.
Anyone offer any help?
Cheers

I made a rollback on my friend's ELS-N29 (C432R6) hw-eu from .196 to .131 today.
Went smooth, just use up-to-date HiProxy and HiSuite with version ending on 550, not 510 as I seen in multiple guides in the internet.

Write the full version of HiSuite to avoid confusion, please.
You want to say 10.1.0.550. Because the current version is 11.0.0.550.
@pape100
Today it was a problem with https://www.firmfinder.ml/
Pay attention to your phone region (Cxxx). Don`t use other region files.
Have you tried this?

Software install failed when trying to downgrade

I know many folks have tried to downgrade and there are many people with suggestions to downgrade Mate 30 pros.
Mine is a LIO-L29, region C637, with firmware 11.0.0.215, using Android 10, but after 9 attempts, however, none have worked. I always receive the Software install failed after about 45 minutes of downloading and I installing a previous version.
I have followed the instructions to the dot by systems hacks (
):
I downloaded HiSuite 11.0.0.510, downloaded HiSuite Proxy, from firmfinder.ml, I selected LIO-LGRP2-OVS-10.0.0.134, LIO-L29-CUST 10.0.0.6(C636), and LIO-L29-PRELOAD 10.0.0.1(C636R8), as those were the ones matching my phone.
I add the roms to HiSuite Proxy, start HiSuite 11.0.0.510, and it allows me to downgrade to my selected rom, 134.
So far so good. I wait the necessary 45 minutes, HiSuite tells me the update was complete, and every freaking time, I receive the Software install failed on my phone after about 4% of trying to verify the update.
I have tried using windows 7 and windows 10.
Am I the only one getting this message? Is my current version (11.0.0.215) not downgradable? Am I doing something wrong?
Is there any other way to try to downgrade?
Any help would be greatly appreciated.
Thanks!!!!

same issue here. seems like once we are at 11.0.0.215 theres no coming back. Will sell this phone, cant live without native GMS as majority of my needed apps needs native GMS

Is that a fact? Is there no way back from 215?

Can anyone confirm that it is NOT possible to downgrade from firmware version 11.0.0.215?

yes you can no longer downgrade once youre in 215

Thank you Leejon10, but as a healthy skeptic, would you mind sharing your source or what you're basing your conclusion on?

I also tried so many time, but still failed . one of the youtuber msg me to do the process after update EMUI 12 beta . emui 12 also limited . so we have to wait for some tricks from developers. i'll also try downgrade via Sigmakey tool. will update here.

Thanks a bunch. Would love to see whether you managed to succeed with Sigmakey.

qualquer solução de downgrade 11.0.0.215? Fiz cerca de 15 tentativas com vários roms, e quando chega a 4% de verificação de atualização, dá um erro.

solution downgrade 11.0.0.215 ?
I made about 15 attempts with several roms and when it reaches 4% update check, the error.

today the update for 11.0.0.236 arrived, would it be good to update?

have you tried downgrading to an earlier EMUI 11 version like 11.0.0.151 for example?

That doesn't work either, I tried it. So what it seems is that from 11.0.0.215 onwards (mine has 11.0.0.230 now) you cannot downgrade EMUI on Mate 30 Pro, for any version whatsoever.
When it comes to P40 Pro though, it seems you can still do it, no matter what version of EMUI you have installed.
Question: Will hackers be able to get around this? Or is it that because Mate 30 Pro is a phone with more than 2 years, they won't even be working on it..

Wear OS on Huawei P40 Pro?

Hey guys,
I'm using my Huawei P40 Pro for a while, now. Everything worked fine, I basically never needed GMS / Google or I could find good workarounds. Now, I've bought a Suunto 7 Smartwatch; their customer support told me it should be fine and working. But the "official" Wear OS app tells me my phone is not supported and I need to get a Chinese version. After installing said Chinese version, I can connect my phone to the watch, but right after connecting (when retrieving data from the phone), Wear OS (Chinese) tells me to install the "official" version from Google Play Store when being outside of China (which I obviously am; in Austria).
So, I've also tried to do a rollback / downgrade of EMUI (currently installed EMUI 12), but the "official" downgrade via HiSuite does not work, the option does not exist. I was hoping to use the Googlefier method, down on EMUI 10.
I've tried Gspace and microG, but nothing works.
Can you help me out?
I basically just need Wear OS working with my watch.
Thank you very much!
