Thank you, I will try to follow your steps and be able to activate the usb to be able to downgrade it is the only way I think.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
But how did you get that 10.1.0.216?
[Huawei P40 Pro Guides, News, & Discussion] djhaz:
Lo conseguí comprando en una web

Hice modo revovery, venía formateado de fábrica pero me aparece la misma versión que instalé y aún no uso el traspaso de archivos de cable a pc. Cuidado conectando un pendrive, aparecen las pestañas para transferir datos, pero se congela en carga inversa y no me permite seleccionar las demás.

hi, am from UAE region,please help me to downgrade to emui 10View attachment 5554191
[Huawei P40 Pro Guides, News, & Discussion] djhaz:
I did revovery mode, it was formatted at the factory but the same version that I installed appears and I still do not use the transfer of files from cable to PC. Be careful connecting a flash drive, the tabs to transfer data appear, but it freezes in reverse loading and does not allow me to select the others.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
On eRecovery you dont have to reset to factory settings. You have to go to Update mode\ eRecovery mode\Update and recover system and see there is a new version.

Regarding flash drive, it is OK to be on Reverse charge.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I don't know if it will work on your C185.

Read B point and Notes here. It worked on C636 with C432 firmware (11.0.0.220).
[Huawei P40 Pro Guides, News, & Discussion] GMSrookie:
Thanks a lot, really appreciate your thread and help!

Got a succesful installation of GSM, and everything seems to work perfectly fine now. Anything I should do before trying to upgrading from my 10.1.0.121? Currently I've turned off auto-updates in order to not make things worse. Considering just keeping 10.1.0.121 since it seems to work. Wanna recover some files from a backup, but guess that's something I've gotta to after I've got the USB-cable to work post-upgrade
[Huawei P40 Pro Guides, News, & Discussion] djhaz:
You are great my brother, I was able to update in recovery and now I can use the USB, thank you, thank you very much. you are a genius.

Hello badmania98 i downgrade from 12 to 11.0.0.260, what do you recommend to do next, i tried 10.1.0.131 but it seems that it doesn't work, and what is the difference between firmware and deload?

You have to follow A 1 and 2 from here + Firmware from Notes (1).

After that follow A 3 with this:

I tried what u said, i tried Christmas gift and i follow the Notes download firmwere try usb and i tried offline but it seem like it doesn't accept downgrade (my version is 11.0.0.260, to 10.1.0.121 or 10.1.0.131)

What should i do next?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
According to that tutorial you have to:

1. Downgrade (DLOAD method) from 11.0.0.260 to 11.0.0.230. You have the link to firmware on Notes.1

2. Downgrade (HiSuite proxy) from 11.0.0.230 to 10.1.0.121. You have the image with files that you have to select on HiSuite proxy on my previous message.
[Huawei P40 Pro Guides, News, & Discussion] mohe77:
I downloaded the file (DLOAD) 11.0.0.230 from ur link, and u can see the steps i did, it keep saying failed, when i try Usb updating mode it stock in 2% then faild
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I understand. You better try another device. A OTG+pen drive or a USB-C pen-drive. What is happening to you is not new, But with other device maybe you will have success.

Hi. I have a question for you @badmania98. I have a p40 pro with working google services but for some time now i get a message about gms update, otherwise google maps will stop working. I have gms on 20.09.14, can I update it without any problems? if so, which version can I do it for and how?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
www.apkmirror.com + v.21.24.56 for Google Play Services.

Fix the error if they are.

After a few tries some youtube tutorials to fix notifications in gms installed with googlefier I noticed that phone is taking screenshots... From time to time when switching running applications the screen flashed for just a fraction of a second. I suspected it wasn't natural and it shouldn't be, and only sure about it after that my banking application shows me the notification that it is not allowed to take screenshots of sensitive data... So I've finished my adventure with installing gms. I did a factory reset and rollback software to emui 11 with latest hi suite but I'm not sure if I got rid of this ****.

Does anyone know which software flash method formats the system partition?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Wow. I have never heard before about something like that (screenshots in background). You didn't mention what tutorials have you used. What phone do you have?

Taking screenshots without send them ...somewhere is useless. And is that known you cannot take a screenshot of sensitive data (bank, etc). So, what is good for?

Post here the links to the tutorials that you think made this.
[Huawei P40 Pro Guides, News, & Discussion] zlo2107:
Huawei P40. I didn't mention because I've used many in the hope that I will eventually fix the notifications and I'm not sure who might have caused it. I don't want to make false accusations. If you are interested I can send you all that I looked at that unhappy day on priv.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Sure. Use PM. I have more then 150 members on my private support group with notification fix installed. No complains till now. I know almost all the tutorials from YT regarding GMS and Huawei. I haven't seen something suspicious.

In my opinion it seems to be a configuration that made this: pressing a key= making a screenshot.

This is an example from my phone:

[Huawei P40 Pro Guides, News, & Discussion] zlo2107:
Hmmm maybe, but I'm not convinced, I do not use navigation bar. I can be wrong of course - there is a moment when I become a little bit suspicious about that all gms stuff and start to over-analyzing and nit-picking.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It was an example.

I've tried every version of HiSuite mentioned in here to downgrade my P40 Pro from 12.0.0.218, mine is ELS-NX9 from Indonesia.

Each time I tried to downgrade, the version available is 11.0.0.259, each time I try, it keeps saying failed to upgrade.

Any help is appreciated.

Vince
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
As I know C301 firmware is... special. So, when you try to downgrade with 11.0.0.590 HiSuite, it made all the process (downgrade the files on computer and install on the phone) and after restart you get the error?
[Huawei P40 Pro Guides, News, & Discussion] vsaber:
Hi Suite didn't even manage to install on the phone, so before it starts the install process it just says failed.

The only option available is 11.0.0.259, I have used 4 versions of Hi Suite and it didn;t make a difference.

I just did hard reset and tried again, it still says "failed to update"

Very strange
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I still dont understand when you get the error.

On the following image you can see HiSuite 11.0.0.590 (no proxy used) during downgrade process.

A= downloading part, from internet to computer

B= installing (it copy the downloaded files) part, from computer to phone

There is a C part after this process, when phone reboots and install the firmware on the phone (0-100% circle). This C part is not related to computer.

When you get the error?

No yet, from EMUI12.

Greetings.

After updating from 12.0.0218 to 12.0.0228 the fast charging with native SuperCharge(40w) and original cable(5A) stopped working.

When connecting to the power supply - the following notification is displayed, which says(in russian): "The charger you used does not support fast charging on this device."

Has anyone had trouble with fast charging after the upgrade?

Man, I tried everything that you are describing here. I have tried the ROM that you indicate in the notes and it's always failing. I also tried to update from recovery menu and from that code that we put in the dialer and the result is always the same. My phone is a P40 Pro and I downgraded it from EMUI 12 to 11.0.0.260 using HiSuite but now I am not being able to downgrade to EMUI 10.

Please help me, it's a lot of money for a paper crush. I don't know if i am doing everything right even if i am following a lot of YouTube tutorials.

Hello

@badmania98 Thank Your for work on this topic.

I have successfully downgraded(ELS-NX9) to 11.0.0.230 (with dload) from 11.0.0.260.

I cant downgrade to 10.1.0.121 or 131 with HIsuite proxy.

Is there any other option? Another dload option?

Thank You
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I haven't tried this solution, so it is your decision:

a. Downgrade DLOAD to 11.0.0.151

b. Downgrade DLOAD to 10.1.0.176

c. Downgrade DLOAD to 10.1.0.121

With NM card. It is possible OTG + pen drive to not be recognized on these firmwares.

What HiSuite proxy have you used? What error did you get?

Hello.

A lot of us failed to downgrade from EMUI 12 to EMUI 11 using hisuite. As mentioned by @badmania98 it is no longer possible for now. Why dont we try all to downgrade via the dload method. We don't know it might work besides this is a new release rom. Its only my suggestion or maybe its a *****ing idea.

B.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You cannot use dload. You have to use a specific version (last EMUI11). We tried today from First EMUI11 to last EMUI10.1. It didnt work.
[Huawei P40 Pro Guides, News, & Discussion] itiloo:
For my part, I have already tried to dload several versions 11 without success, but not 11.0.0.206 since there is no dload for that version.

In the case of the huawei mate xs, the latest version 11 is 206, but I can't find it.
[Huawei P40 Pro Guides, News, & Discussion] Bongsi:
Really. I am searching the last built no 11.0. 0.260 is not yet available I guess. So for now we'll wait that built no. Or wait for huawei to fix the issue on hisuite. Thanks anyway @badmania98
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
Have you guys tried what badmania98 said? Contacting your local Huawei support center, and see what they tell you? In my case they sent me instructions, and told me to contact them again in case it fails. This is an official rollback, it must work.

On the international version +users there are 2 issues when you try to downgrade:

1. Message: No internet connection. We have to change DNS. Nowhere is mentioned that on their site/instructions.

2. Message: Failed to update. This is just in case you solved the first issue. This is a problem from their servers too.

That is what we have to mention.

I always use china DNS 114.114.114.119 and 114.114.115.119 or protonvpn from usa for example to avoid the first problem
