Software install failed when trying to downgrade - Huawei Mate 30 Pro Questions & Answers

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..

Install Huawei HiSuite on your pc and connect phone with your usb cable.. hit update and it should update your phone.. I think it may do it incrementally.. so 9.0 then 9.1 and finally 10.0.. You will see...
Look at this thread.
https://forum.xda-developers.com/huawei-p20-pro/development/emui-10-hisuite-proxy-t4109035
If you need any informations I can help.
Yeah.. was able to figure it out.. and am currently in 9.1 using the HiSuite via PC. Is Android 10 update worth it? If so, i will do it manually via firmware finder method.

Yes, it's a pure refresh from 9.1 (a crappy port of Android 9.1)
The firmware finder way is not working anymore. You can use the app to get the links. Nothing more.
You need Hisuite Proxy and Hisuite.
See my posts and everything.
After sometime, again i got few more updates,, and i am currently downloading Android 10 again.. So atleast it wil be with latest security patches.. lets see how it goes..
Btw, i saw a GSI image of Android 10 for P20 Pro. any one uses it here?

You can't use it unless you unlock your bootloader, which Huawei stopped doing. They then proceeded to remove the method used to unlock the device in Android 10.
Yeah.. i just found out.. its so sad.. its such a beautiful device,, unlocking would have let me use it for a long time now..

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?

Emui 12 to Emui 10 to Emui 12(no update, still 11.0.0.230)

Hello friends. I have a P40 pro. I was using emui 12 beta, but I downgraded it to emui 10 to install gms. After installing GMS, I made all the updates in order (5 total, updates as large as 10 gb), but now 11.0.0.230 appears as the latest version, the emui12 update does not appear in hisuite, do I need to log in to the beta project again?
I joined the beta program through the UK country, checked it using appgallery and system UK, but there are no updates.
How to downgrade from emui 12 beta to emui 10 please?

Hello, did you solve the problem?
I got stuck on .230 for few months, but last weekend I've changed my SIM card few times (I've used Polish SIM and I immediately got update to .260, then I put giffgaff and i immediately got update to EMUI 12 .218).
Im also stucked for 2 months on .230 version, cant update to 260 or emui, tried everything and even did factory reset but sill no success.
Didnt do sim swap since i only have my sim from bh telecom (bosnia)
Upgrade chart procedures (generally speaking): here.
hm it seems my only option is to use hisuite proxy, can you explain me how to use it

There is no 260 or EMUi12 firmware available on HiSuite Proxy or DLOAD method, yet.

P40 pro downgrade - different device

Hi, just got my P40 pro and decided to install GMS. I've read a couple of guides and started...
Downgraded to EMUI 10 and lost USB connection. My device name changed from ELS-N29 to ELS-NX9. Did OTA updates up to EMUI 12 but still got NX9 as device name. Tried downgrading again via Hisuite and got error message Update Failed.
Shame that none of the widely available guides addressed any of the problems I have encountered, had to specifically look for them to see all the warnings related. I've noticed there are other ways to install GMS but downgrading still seems like the easiest option. Why ELS-NX9 though, and why Hisuite won't proceed?
First time downgraded directly to 10.1.0.154. Used correct files (C432, ELS-N29, R5). Now I am trying to follow THIS guide, but got error message from Hisuite.
What am I doing wrong? How to become ELS-N29 again (if it changes anything) and how can I install GMS and go back to EMUI12 the most hassle-free way? Got quite a bit of experience with flashing, using recoveries etc, so I thought it's gonna be sweet-as-pie job....

You used old tutorials. I think you can find many things on my thread here.
I'll try downgrading to EMUI 11 using Hisuite without Proxy then. I've seen your thread about fixing USB connection etc, but other people said over there that their device became N29 again after some OTA updates. Mine didn't.
I also wonder why my device originally was N29, but ny box says it's an NX9...
If I manage to downgrade to 11 through vanilla Hisuite, will I be able to follow the video I've linked above? It seems pretty straightforward, and If I only seen it before OTA upgrading...
Does my device being NX9 actually make any problems? Or it was just wrong Hisuite/random error then?
Edit: okay, I rhink I see now. So right now I should downgrade to the lowest thing Hisuite will let me, then Hisuite proxy to lowest 11 version, then I should be able to continue as per video. Correct?
EDIT: Okay, not correct, I won't be able to downgrade from 11.0.0.260 any further without OTG according to your guides. Don't have one at the moment.
I've also found this thread. Could I simply stay on EMUI12/HarmonyOS (whichever I have if there's any difference) and install GMS this way? If yes, I'd like t repeat previous question - does my device being ELS-NX9 now instead of originally ELS-N29 affect anything at all? Regards and cheers
Yet another edit: how is it possible that I downgraded from EMUI12 to 10.1.0.154 directly in the first place? Used newest Hisuite with Proxy. According to all guides, including yours, this should not be possible?
