I want to thank @badmania98 for the prompt response to ky problem regarding downgrading a Mate 30 pro C432. After several attempts and the help of him I didn't manage to downgrade my phone from Emui 12 to install GMS but I decided to just wait for a newer method. The phone is GREAT even without GMS.
The man is a master in the field and very keen to help everyone at once! It is because of people like him that I appreciate the work that is being done in this forum! Keep at it my friend...
Excelsior badmania98!!

My current p40 pro version is up to date (11.0.0.230 C432). The GMS used to work normally when Google Play Service version is 21.48.18 (100400-414534850), and Google Play Store version is 28.9.12-21 [0] [PR] 421882020). But it suddenly pops up protect issue when
I tried to add a new visit account in my phone. Now all Google Apps including Google Play Store cannot work. See the attached picture below. I've tried to uninstall/install the Google play service for serveral times but they seem no use.
Can I get some professional advice from Mr. Badmania98?

Many thanks for the prompt reply. Yes I did read your first page very carefully and I'm going to repeat method v1 to v4 once again for good luck.
Can I ask a question straightaway, i.e., is it necessary and possible to re-install google play store without downgrade firmware to 10.x.x.x?

Sure. That is why I told you to not reset to factory settings. I think you have all you need on the first page. Let me know if it is OK.

    @Eini666 and @badmania98 you glorious bastards.
    EMUI downgraded to 10.1.0.121

    About to install Googlifier.

    As usual, you guys find yourselves in Prague beers on me <3
    All thanks should go to to @badmania98 I only had to downgrade and install GMS 3 days ago, so I just read the entire guide and I still remember what and how.

    Hello everybody!
    I'm here to thank @badmania98 for helping with installing notifications for GMS services for a Huawei P40 pro.
    I downgraded from EMUI 12 following the steps described on this thred. I also had a weird problem (maybe others had it) - downgrade to EMUI 10 via OTG connection from a 64gb Kingston stick didn't work - the stick was formatted correctly. It was solved by using another older 8gb stick.
    After installing the GMS services, I contacted @badmania98 who was willing to help me the same evening - the process took an hour or so, during which time thousands of steps were taken - I consider the price for the service more than fair.
    Very good communication and the best result!

    Hello there,

    I am having a bit of an issue here, maybe you can help me out.
    I had EMUI 12 - Huawei P40 Pro (factory reset) and I downloaded latest official HiSuite to downgrade to EMUI 11.

    So my info was:
    Build version: 11.0.0.249
    Model: ELS-N29
    Region: C185
    R number: R4

    Edit 1.0:
    Followed your instructions and I downloaded a DLOAD file provided by you for version 11.0.0.230 (used your C432 instead of C185) (C432E3R6P4) and now my phone info reads:

    Build: 11.0.0.230 (C185E6R4P4). There was no change in region it seems?

    THE (UPDATED) ISSUE
    I am unable to use HiSuite or OTG method for whatever reason to downgrade to EMUI 10 to install Googlifier.

    A) I tried using HiSuite Proxy for ELS-N29 C184 (R4) to roll-back to 10.1.0.114 and 10.1.0.131 both. But soon as the files are 100% downloaded I get error "Failed to update"

    B) I downloaded DLOAD for 10.1.0.131 (from your old post) --> Elsa-N29D 10.1.0.131(C185E9R4P1). But when I try to install from recovery mode I am getting: "Software install failed: incompatibility with current version)

    Please tell me what am i doing wrong here, I spent all day reading and re-reading your instructions not to be lazy but i'm hitting a wall for whatever reason....
    Which hisuite version are you using to downgrade ? Latest version V11.0.0.610 you need only do downgrade from emui 12 to latest version od emui 11 and to have latest version hisuite app on the phone.
    After that you need to uninstall hisuite from computer and install 10.1.0.550_OVE-BUN but only on computer with no upgrades of firmware in phone and computer.
    Hisuite Proxy and Hisuite 10.1.0.550 will give you possibility to downgrade from 11.0.0.230 to 11.0.0.121

    Thank you @Eini666

    With husuit proxy but could not find firmware below 154
    That is because you used v2 on firmwares page. You have to use without v2 on the address link

    This is good for you: here.

    I am waiting for your questions. I hope that I can help. I will not answer again if I already answered and you haven't read first 7 messages of this thread. I don't like people who are more lazy than I am. :devilish:

    Here is my guide: - here.

    <11.0.0.260 to EMUI10.1.121( P40Pro C432) EMUI downgrade tutorial - one step : here The procedure is the same for all Huawei phones and regions. You have to use the specific files for every region and phone type. Ask on thread if you dont know what files you need.

    5. HOW TO flash DLOAD FW guide: here

    6. The transfer files between Computer and phone is available on the downgraded firmware (10.1.x.x) when you use a certain USB-c to USB-c cable. In this case a UGREEN, US355, USB-C To USB-C, 3.1, Gen.2, PD, 5A, 100W, 4K, 10 Gbps cable has been used. In the same time, using the original USB cable or other ordinary USB-c to USB-C cable have not activated the file transfer.
    Harmony TP cable works also, in case your computer/laptop doesn't have USB-C port. You can build/make one (search the procedure on YouTube).

    Hello everyone,

    I want to share my experience here.

    I posted earlier a problem on xda "Can't downgrade P40 Pro ELS-N29 C432 from 11.0.0.260 to 10.1.0.131"

    I tired many solution for several days and nothing worked!
    Then I contacted badmania98 and he gave me the right and only solution to downgrade my P40 Pro from 11.0.0.260 to EMUI 10.
    He provided me with the corresponding links and gave me a step by step procedure, shown in pictures that are highlighted by numbers..
    " 1. Press this 2. insert that 3. etc... " and then he doubled check my work before I proceeded in Hisuite Proxy to make sure that the filled info about base, Cust, Preload and the software are 100% accurate.
    I was able to downgrade my P40 Pro to EMUI 10 😁

    Now here's the best part: He gave a private service and installed GSM on my phone using TeamViewer. He used his own files to install GSM on my phone... This service allowed me to have Google Push notifications working on my phone without disabling the Google Play Store 😁
    Google service is working, maps, push notifications, everything related to Google is working now as if this phone originally had Google Pre-Installed in it 😁

    It was a great service!

    Thank you so much
