I see the image. That is what is written about DLOAD method in my tutorial? Have you read first 7 messages of the thread?
Point 5 on Message 2.
If you mean this- YES. I really do not understand what I am doing wrong.

„USING OTG ADAPTER or OTG CABLE + USB MEMORY STICK
1. Extract dload folder from downloaded archive above (dload folder with all 3 zips inside) and copy to your memory stick / drive >=8gb (formatted as exFat or NTFS) that will be used to upgrade
2. BACKUP your stuffs if you haven't done yet
3. Factory Reset your phone (optional) and POWER it OFF
4. Insert your OTG + memory stick / drive with the correct firmware on it (dload folder with all 3 zips inside)
5. Press Power button AND vOLUME + and as it vibrates and shows Huawei + Android logo WAIT FOR 5-6 seconds and release buttons, and the phone will enter in eRecovery mode. When in menu, select Update mode, then select Memory card/OTG update mode and it should start the update.
USING Huawei NM Card
1. Extract dload folder from downloaded archive above (dload folder with all 3 zips inside) and copy to your Huawei NM Card
2. BACKUP your stuffs if you haven't done yet
3. Factory Reset your phone (optional) and POWER it OFF
4. Press Power button AND vOLUME + and as it vibrates and shows Huawei + Android logo WAIT FOR 5-6 seconds and release buttons, and the phone will enter in eRecovery mode. When in menu, select Update mode, then select Memory card/OTG update mode and it should start the update.
OR
If you want to do it from sistem after you've made your backup and had an factory reset (optional), insert OTG + memory stick / drive OR copy dload folder with all 3 zips inside to your Huawei NM Card and dial this on dialer *#*#2846579#*#* and select 4.Software Update then 1.Memory card Upgrade . If your inserted card / memory stick or USB drive or Huawei NM Card it's recognised and contains the right files, phone will restart and start flashing the firmware. At the end when it's restarting after succesfully flashed firmware, you can remove the OTG (if you used one).

You didn't do that. In your image with card content is a mess.

I think you don't understand what I write. I changed the font and colors, maybe is more clear. I answered very clear what you did wrong here.

Noup. In your card root should be DLOAD folder only. In DLOAD folder is its content.

I didnt open this thread to explain what a folder means.
I did it, now I am rolling back through HuSuite installing following versions, but I will try it do it in offline mode.

    Hey thanks for the tutorial so far!
    I tried to downgrade with hisiute proxy.
    Phone : Huawei P40 Lite JNY-L21 C432E1R6P1.
    First downgrade from Emui 12 to 10.1.0.399 was done with original Hisiute.
    The next downgrades failed after the reboot (failed to update).
    Should i try dload method? I found a firmerware :

    JNY-L21 10.0.1.136(C432) [LZPlay, GMS, GoogleFier Possible] Huawei Official Firmware [Stock, dload] [DG]

    Is this suitable for my phone? Can i downgrade from 10.1.0.399?
    1. First ”dload” to ”Huawei P40 lite (Nova 7i) JNY-LX1 JNY-L21 hw eu Jenny-L21A 10.1.0.364(C432E1R6P1)_Firmware_EMUI10.1.0_05016PMS.zip”
    2. And after that with HiSuite Proxy to 10.0.1.136

    2. And after that with HiSuite Proxy to 10.0.1.136
    For 1 is no ”zero b”
    For 2. is ”3”
    On first page message no 2.

    I read that. I understand that for dload R version doesnt matter. But i thought for HiSuite R-Version matters. Therefore i am confused. And since we are changing from 10.1.0.xxx to 10.0.1.xxx we need preload and cust right? Maybe i am missing something anyways thanks for your time!
    You are right. In HiSuite proxy you will select the original R.

    I got your point.

    @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!

    Because I answered to the same questions on different threads, I decided to create this thread, where I will provide my experience to you, in one place.

    The followings messages (2-7) contain all major info and tutorials links from this thread.

    All solutions/tutorials are related to the EMUI version that is installed on your phone. Before you start using this phone and upgrade/downgrade the firmware, I suggest you to read this message and after that you can continue reading the thread.


    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:

    My Phone: P40 Pro C432 EMUI12, push notification fix installed.

    Best regards,
    Daniel

    LE: My support on XDA is free of charge. I will provide/mention free solutions. If you find something interesting on my messages you can provide a Like.
    On PM/Telegram I could provide different solutions that could be not free of charge.

    Here is my guide: - here.


    2. EMUI downgrade procedure chart - here.

    3. from EMUI version
    <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.

    4. Firmware Downgrade with HiSuite proxy and Offline Packages: here (AVOID IT).

    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
