I'm getting there, still got my mate 20 pro as a spare so that's what's tempting me to try your guide,but worried I'll find it difficult. I've not done anything like this since jailbreaking an iphone

Is there a YouTube guide?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
No, is no guide on YouTube from top to bottom, because there are changes all the time. Just in my head they are all updated.

What firmware and region is on your phone?

Where can I get the dload files for upgrade? From 10.0.1.167 (c636) to 10.1.0.226 (c636)?
[Huawei P40 Pro Guides, News, & Discussion] jikuri:
Alternatively I found a video where he could bypass the USB connection using a certain hardware, the thing is he didn't even name the hardware he used so I could not search for it. :/

Heres the video:

Another video where he used it:
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Nah.

with dload you will delete GMS. It is written there.
[Huawei P40 Pro Guides, News, & Discussion] jikuri:
I don't care at this point, I just want my old stuff back.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Do you have USB-C port on your laptop/computer?
[Huawei P40 Pro Guides, News, & Discussion] jikuri:
Yeah I do

I think you didnt read first message of this thread. And after that see message no2. point no. 6.
[Huawei P40 Pro Guides, News, & Discussion] jikuri:
I just used a standard USB-C with OTG before and it didnt make a connection, maybe it doesnt fit the criteria. I'll try out the cable you mentioned and I'll update how it goes 👍
[Huawei P40 Pro Guides, News, & Discussion] Bettz:
Hopefully that helps
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Yes. Downgrade is needed, after that install GMS, upgrade, fix errors and install your apps. Minimum 4-6 hours of work if you know what to do (except install your apps).
[Huawei P40 Pro Guides, News, & Discussion] Bettz:
Thats a relief so it will work on my phone.

Can you do all the updates after without any problems? Today I got a Hms core update but I'm unsure if u can do it.

I'm using gbox method atm and have managed to figure all that out.

Any help on what phone firmware I'd need to download that's the bit I'm most worried about.

I have just added some mentions on Upgrade post (chart part).
[Huawei P40 Pro Guides, News, & Discussion] Bl4ckIn:
already try it with dload after upgrade gms is gone and tablet back to factory reset, already trying dload from 131 to 151/157, maybe because it's matepad pro maybe it's different on p40
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I don't say anything in contrary. I always said that regarding dload. Upgrade or downgrade will erase all personal data, as reset to factory settings does.

I read so many messages and wacthed so many videos about how to downgrade phone with hisuite proxy and dload methods and I have done it like you mentioned in page 74. I downgrade it first 10. ... 399 then 364(e1r6p1) (dload method) then with proxy 10 ... 136 .

Everything was good but I can not use usb at all. I upgrade with ota but nothings change. I stuck with it

last before (364)

My model: JNY-LX1, P40 Lite;

Base version: JNY-LGRP2-OVS 10.1.0.399

Preload: JNY-L21-PRELOAD 10.1.0.1(C432R2)

Do I need a test point cable

or

Can I dload phone to 10....399 with *#*#284.....#*#*
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Dont use dload firmware. Read Upgrade message on the first page.

You have to upgrade several times.

On my P40 Pro I have to upgrade 3-6 times from 10.1.0.121/131 till it gets 11.0.0.2xx.

Thanks for your disponibility and for your help.

you took all your time to explain me, 1, 2, 3, etc
[Huawei P40 Pro Guides, News, & Discussion] tuzeimum:
how do you upggrade several times? Do you mean "checking for update time to times and when it gives you final update" or "do factory resets until find last update" ?

when I check updates after factory reset, it gives an update immediately for local telecommunication firm apps. I did that upgrade (it is exactly the same only gives a few local firm's apps and Now I wait for an update.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
"checking for update time to times and when it gives you final update"

Install first available upgrade and after restart search for the next upgrade. So on.
[Huawei P40 Pro Guides, News, & Discussion] tuzeimum:
but nothings seem on upgrade menu on ota. It says "it is the final upgrade"

If I use the cables with huawei usb 1.0, can I use hisuite proxy to change emui version?

For now I cant use usb cables or flash disk features

So I tried so many method for gms to solve those but I take different issues all of them. I need it only wp app for Google drive recovery and gbox app giving to me that. for other recovery and backups (names, notes, gallery) ı have already use Huawei cloud.

so I dont wanna use gms and I will use dload method, thanks to turk telekom (turkish ****ty operator) ı dont see any upgrade with ota and stuck on 10...136. WiFi upgrade not works also. cannot use usb features.

There is a video on YouTube "no hota updates" "no usb connecon" and he says try bunch of usb flash drives, some of them works like sandisk and transcend

Hello @badmania. I have a Honor V30 Pro which basically runs on huawei software. In the past I had been able to downgrade to the oldest firmware and install GSM services. The oldest I can go back to is July 2021 firmware for my phone. I want to go to 2019, my phone model number is OXF-AN10 region COO(zero,zero). Can you please help me bro?

The same principle applies for the phone I had done it before but can't remember the procedure. I have successfully downgraded from harmonyOS to EMUI 11. Now I need to go to EMUI 10 but it does not work. It goes to as for as downloading the firmware and rebooting but cancels when the phone boots to recovery mode and after 4% asks to reboot. As I understand from your forum in order to go to EMUI 10 from 11 I should have proxy 2.3.4 and hisuite version 10.1.0.550

They are not approved. I think you don't need lower than 10.1.0.131 for GSM install. What do you want to do? What region is your phone?

Basically go to google play store and setting set auto-update apps to off. That way google services will not update. That is very important. You do not want GSF to update otherwise you will get that pop-up everytime! You will at some stage have this error regardless.

[Huawei P40 Pro Guides, News, & Discussion] Christian211321:
It has in the firmfinder there a versions for harmony os. But should i really Update via ota when its avaible to emui 11 and then with hisuite proxy with base, cust and preload package from harmony os to harmonyOS? Will i still have GSM??
[Huawei P40 Pro Guides, News, & Discussion] Christian211321:
And where can I disable auto updates in playstore?
[Huawei P40 Pro Guides, News, & Discussion] brownboy1289:
nono do not do anything with hisuite proxy now that google services is installed. Let the OTA updates come on your phone. It could maybe brick your phone and it will reset it that way. OTA is the safest way because it does not erase the data. You will have gsm even if you update to latest version for your phone.

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You cannot reach 10.1.0.131 C301 with HiSuite Proxy. It is not approved.

You can get any 10.1 firmware that is approved with HiSuite Proxy, and after that downgrade from that 10.1 to C301 10.1.0.131 DLOAD firmware IF YOU HAVE IT.

If you dont have it you can try (IT IS HIGH RISK TO BRICK YOUR PHONE) with a C432 DLOAD 10.1.0.131 or 121 firmware.

After downgrade and install GMS you will try to upgrade to your C301 firmware with HiSuite proxy ( or a mixture of methods, except DLOAD).

This is the theory. It worked on other phones and regions. It is risky. Don't blame me.
[Huawei P40 Pro Guides, News, & Discussion] Arouf:
I have successfully downgraded to EMUI 10.1.0.158 but the USB data transfer is not working and the USB OTG is not being detected in the file manager. I have the Dload 10.1.0.131 file and have previously used it for successful downgrading. However, now on EMUI 10.1.0.158, I have attempted to downgrade using the Dload file but the system recovery is not recognizing it.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
The best method now is to use a NM card. On EMUI11.0.0.2xx (you have USB connection) write the dload on NM card.

You can try other pen-drive. Strange thing, on some phones with some OTG+pen-drive , the dload can be read.

Not for free, it can be written with Sigma or other hardware tools. I dont have them.
[Huawei P40 Pro Guides, News, & Discussion] Arouf:
So there is no need to downgrade to emui 10.1....??? from EMUI 11.0. 0.202 to emui 10.1.0.131??
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Sure it is needed to downgrade first on 10.1.x.x. I told you an easy method to prepare the dload firmware on NM card for the appropriate time. DLOAD is used on the same major EMUi version (10, 11 or 12) not between major version of EMUi.
