Huawei P40 easy firmware downgrade guide / fixes LZ play chinese app install problems

[schumimtl]

So I've seen a few people here complaining they can't install google stuff on their phone because they've upgrade it to the latest EMUI version.
Here's an easy way to downgrade to a previous firmware. This works on the P40 version, but it should work on any P40 variant.

1. Download the firmware of your choice from the web. For the P40 european here's a link (it worked on my ANA-NX9 phone:
https://androidhost.ru/XyS

2. Put the ''dload'' folder found in the zip at the root of a usb stick

3. Attach the usb stick to you phone. I take it anyone knows how to do it. Shutdown your phone. Then press and hold volume up and power button until you get to the recovery menu

4. Select Update mode, then select Memory card/OTG update mode

5. The phone will verify and install the firmware

At this point you'll be able to re-install all the google stuff, no more errors when trying to install the Chinese app. Needless to say, disable automatic firmware updates.

Hello,

I tried to do the same to downgrade my P40 Pro. I've downloaded the correct firmware from androidhost, device version is the same. But I got an "incompatibility with current version" error when selected to update with USB. Any idea what went wrong and how to get it done properly? Thanks!

 

[schumimtl]

make sure you do it thru recovery

Thanks for the downgrade guide @schumimtl

Has anyone (beside schumimtl ) already used this guide with the P40 and can confirm that that the linked firmware really works?
I don't want to brick my phone.

Hi, anyone know where to find firmware for ANA-NX9 C636E6R4P1? I did find anywhere but seems not found. Mostly is the EUR version firmware. Not sure if I flash to EUR firmware, it will cause any problem or not to my device.

Is downgrade deleting any data on phone? Or just changes the soft

Yes, it will delete phone data. It's like you did factory reset.

Thanks for the post. My P40 was downgraded successfully. Now with the GMS installation. So far I have tried 2 methods but was unsuccessful. Stuck with adding google account.
Could anyone recommend a method working on this version? TIA

Can you advise the actual files copied in the USB = i am not able to get the phone identify anything from update.zip. I have tried with the zip and update.app at the root as well
