Hello. I was given Huawei phone for Christmas and it had EMUI 12 preinstalled on it. Is it impossible to downgrade it at the moment?

What phone type, firmware, region, are you talking about?

Read here.
First no. 3. If it doesn't work see no. 0.

Hello after my research I found this version but none for my hw-eu region. Should I use this version for the downgrade? And if so should I also use PRELOAD and CUST even if they do not match or only ELS-LGRP4-OVS 10.1.0.128 file? Regards

Yes. You should use all 3 of them ( that you marked). It is also possible to get an error at the end, because your phone could be on an EMUI11 version (too new) that doesn't allow downgrade.

What phone type, firmware, region, are you talking about?

It's the Nova 8 (ANG-LX2), Is the firmware the build number? If so, it's 12.0.0.138 (C69E9R1P3) GPU Turbo, and it was bought in Mexico. I hope something can be done. I'm a teacher, you see, and I rely on Google apps for absolutely everything I do, and I can't adjust with apps like Gspace, they just don't cut it with everything I need. I really appreciate any information or help you can provide me with (I think we might be going back to online teaching this semester so I'm panicking a bit).

It has been released with Android11 Emui12. You can try with this tutorial. I have no idea if it works.

GOOGLEFIER ON 2022

Googlefier cannot work on ...2022. Pressing on (step) 01 will have no action.
You have to set the phone date to 2021 and googlefier will work.
After migroG has been installed, open it to sign in.
Before sign in with microG, set back automatically for Date.
After your signin , return to Googlefier, skip step 2 and go to step 3.

guys one more question, i have made the modified usb with the 10k Ohm resistor for connecting the phone with the testpoint method, but it keeps saying "usb not recognized" on my pc. Is there a fix or drivers I should install?

 

[badmania98]

@luneo Mate 30 Pro C432 11.0.0.230 downgrade:


Have you tried HiSuite Proxy? If it can not be used (error at the end) you have to use my tutorial (A) here for 1 and 2 use this firmware: https://androidhost.ru/Z8w

For step 3 I will answer after you done step 1 and 2.

I think you have to connect first to the phone and after that to computer (minute 02:00).

You made a big confusion. That tutorial is for Higher version of EMUi (11.0.0.260 for C432) and not for 11.0.0.230 C432.
Was your Phone with 11.0.0.230 C432? In this case you should use HiSuite proxy.

Ok.
Post here a screenshot of About Phone. And let me know what (original) firmware was on it before you use my tutorials.

Same thing happened to me, I have a P40 Pro with 11.0.0.230 C432 and can't use HiSuite Proxy for downgrading, a get an error, what is the best way to downgrade to 10.1.0.121?

For me everything is perfect. Thanks for your help.
In the order I made a backup with HiSuite 10.1.0.550_OVE.
Then I did the downgrade with the Canadian version because the europe version did not exist.
On the other hand, keep the same C792 version in my case. After I installed the GMS services.
Then I did the EMUI updates until I went back to my version 11.0.0.243 (C792E4R3P3) when saving and as if by magic my USB connection and fast charging came back.
I reconnected to HiSuite to re-import my data (contacts, sms, email, photos, videos, documents, some programs but not all and finally some settings but not all).
Now I have the same phone as before but with GMS services.
I just blocked the auto updates from EMUI.
Everything is perfect !
Thank you for everything.

It is not working for what you need.
Ask here.
It is not for free on that site.

Hello there, I asked from this guys to unlock my phone, he did everything right (as I saw) with SigmaKey, but now the phone doesn't boot up to see if this worked. Do you have any ideas?

Have you ask them? It Is their work.
Maybe you have to go to eRecovery and make a reset to factory settings/ low format.
Better ask them.
