Download Full Package (system update)

I noticed some annoying bugs in Emui, so I thought "hey, why don't reinstall the OS" I tried it over HiSuite but it didn't worked out. After that i noticed the "download the full current package" button in System update. The button does nothing, is this normal? I'm just confused asf, the Mate 9 is my first device so idk. I also noticed that Huawei isnt offering the full roms anywhere where the public can find it easily. OnePlus & Samsung did a better job there... Is there even an easy way to reinstall the OS or update it manually?

Yes. It is normal when System Update doesn't download "full package", cause it checks current and choose not download same version.
And yes. Huawei doesn't offer full ROMs in easy places. They post all ROMs on HiCloud (Huawei Cloud Resource) silently. In a few cases they can post ROMs on Huawei official site, but it is too rare.
Huawei thinks that no necessary to told everyone that new version is coming, cause they are using method with OTA updates.
And no. There is no easy way to reinstall OS or update manually, but with some exceptions.
Current free method uses modified recovery to force update. It requires bootloader unlock procedure (unlock forces factory reset procedure). Additionally method requires some knowledge how whole process is running.
There is paid method also. It is easy in general and you should DNS setup only. But a few percents are choosing pay for service what helps people to install free ROMs.

Are you serious ??
@idealfall1
The easy place to download firmware is firmware finder on Google play store they have all Huawei firmware for all model...
Or we have this site
http://hwmt.ru/oth/HWFF/info/view.php?find_model=
Find your model number and download it.
And for finish we have a very very easy way to force re-installing firmware without root or flash recovery or paid solution or unlock bootloader... It's the 3 button method !!!
Create a folder in external SD card, call him dload and put firmware (update.app) in, turn off your phone press volume down + volume up + power in the same time and voilà
Sorry for my bad english

Huawei Firmware Finder is private project of enthusiasts. They don't host any firmware and only help people to find ROM in HiCloud. But question from idealfall1 was why Huawei isnt offering the full roms anywhere where the public can find it easily. Other manufacturers do it.

Do you have Mate 9? Did you try install something with 3-button method? I tried many times. It is not working.
In case of Mate 9 Huawei added special tag "UPDATE_ONLINE" in rom. And most roms are with this tag will not install via 3-button...

If you are right, so it is very good news!
5 or 6 months nobody can't install roms via 3-button. There are only 3 service ROMs with tag "offline_update".
What exact version do you have? I will download and check for tag.

Ok, conclusion time. Mate 9 users cannot update via 3-button because of this special flag/string. Does the firmware finder work? It's technically an online update, right? I'm a little bit confused... Firmware Finder found for me some FWs from june... Can I install them? Sorry I'm not looking through this mess xD

When I buy it they are in b126 version and upload on b138 but if the 3 button method don't work for update firmware like you say may be can work for him because he want flash the same version of firmware, are you fellow my reasoning ?

If you're using FF, you must know that it forces ROM to system update.
Workflow is simple:
1. Find ROM
2. Force to system update
System Update will download ROM by self, like update is coming from Huawei officially.
But Huawei prevents this trick on very new ROMs and additionally checks for authorization.
In it's turn, FF can check ROM too, tries to reproduce Huawei's routine.
So, if you want install latest rom, you have to use method with modified recovery to force update.
If you want install old ROM - force update via FF.
P.s. We are all huaweied

Yeah. Good idea.

Three button reset does not work with the Mate 9.
It just doesn't.
You can only factory reset if you're on stock.
That applies to ALL stock firmware as far as I know.

Forced update via erecovery!

Guys! Hello again... I'm still blocked with android 8.1 on elm29 sp5c900. I understand that c900 is global, Huawei still tells me that an update will come soon, but nothing. Erecovery doesn't find nothing on server and hisuite doesn't help me at all. Now the question... Is there a problem if I download an update file from firmware finder and install it with forced update (power plus volume buttons)? Can I brick the device, since I don't have a backup file or original software

Firmware downloaded through Firmware finder won't install via forced update, you can use service ROM (download though androidhost dot ru) and place it on usb OTG and force it. Or you can use patched Hisuite method to update https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/page132
Yes it can brick, anything can happen but very unlikely, just backup your device through Hisuite before trying that if you want to keep your personal data(won't back up firmware, only apps, contacts etc.)

C900 hw/normal does not get any update.
Just force some updated base via dload package or via forced hisuite with dns spoofed.

Thanks for your answers! So... The steps will be... 1. Download "update full base. app"
2. Place it on root folder in dload folder
3. Update it via forced update (power button plus both volume buttons)
I've found on firmware finder update.app file. This works via dload method?

For dload, you ll have to use an USBOTG, exfat formatted.
On 8.1, Use a 9.0 dload's update.app .
Once on 9.0, use a 9.1 dload's update_sd.zip
Alternative is to use forced hisuite.-If so uodzte first to 9.0 then 9.1.

Thanks a ton. I will try with dload. Is more simple

Forced hisuite doesn't work! Gives me only update to android 8.0. Firmware finder on pc doesn't give me my version sp5c900, so I can't download any firmware. Now I don't trust FF on phone neither. What if this gives wrong firmware, since my emui version is not suported. ****

I've spoked (finally) with someone from Huawei on chat, and after verifying my serial number she told me that my phone is a demo version. F%$&. So, no Android 9 for me. Still, my phone works flawlessly. Since I'm stuck on 8.1 I want to root it and play a little more. Can you give me an idea how to root it? Thanks

First, is this device is with an unlocked bootloader ? (and/or do you have the unlock code ?)
To check bootloader/phone status, boot to fastboot/bootloader mode :
Plug device to PC with Hisuite, reboot P20 and Hold volumeDown on P20 until it boot on white screen ;
What is your Phone status ?

Sorry for late response. Bootloader is locked.
"phone locked.
FRP UNLOCKED"
And I don't have bootloader code.

So you won't mind that dload packages are locking back bootloader as it is already locked...

Any way to unbrick a P40 Pro? "Your device has loaded a different operating system"

So like a dummy I flashed the wrong firmware on my P40 Pro. LGRP6 instead of LGRP4. Now when booting it says "Your device has loaded a different operating system" and then goes straight to erecovery. In eRecovery, downloading and restoring the system doesn't work because it fails to retrieve package info.
I already tried everything possible with HiSuite Proxy, too. I read bricking a P40 Pro this way requires to replace the motherboard, but not sure how true that is. My phone is still under warranty, but I'd prefer to fix it myself, if possible.
Any ideas? Thanks.

Tried eRecovery without any sim card in it?

Yes, I just get retrieving package info failed. Every time

Then it seems motherboard replacement is the only known option left.

Same issue with me

I spent a month to fix it and didn't find a way.
I tried Chimera Mobile and it didn't helped.
The only thing that probably can help is SigmaKey software. If anybody has it please check and say did it helped or not.
Huawei don't want to replace it by warranty for me, that is why I try everything.

I can't find anybody with SigmaKey. Probably I'll go to replace the motherboard in the nearest future.
Other methods definetely don't help.
Do you have any update? Please share if yes.

Hi all! My device is finally fixed! It was fixed by disassembly, hardware testpoint and flashing of Android 11 via SigmaKey!
You have to find a very expirienced person to do this work. I can recommend one person in Moscow, Russia in private messages.
Disassembly is probably necessary

After 4 days trying everythingI found also a guy who told me exactly what you are saying. disassembly is required because of the test point. No other way currently.
SoI will go to a phone shop tomorrow to disassemble the back cover of my P40Pro+. Then the guy will do the whole flashing process via remote. But it's paid service for 30$. I decided to do or because I wanna use this phone.

The only other way is to try to replace the motherboard by warranty.
However, in my case Huawei refused me this.
I think 30$ is a good price because it was very difficult for me to find a person good enough to do it.

Hi guys. Just posting a small update here. I found a xda user who accepted to help me unbrick my P40 Pro for a donation via remote desktop. He will be using paid tools and hopefully it will unbrick the device. I'll post another update soon, to let you guys know the outcome. Fingers crossed!

It is not always possible without disassembly. (Like was in my case)
I wish you good luck but be ready for disassembly.

Another update. First of all big thanks to @oslo83 for accepting to help me with my bricked P40 Pro. Unfortunately things didn't go our way and the device is still bricked. The problem is that I flashed LGRP6 EMUI 11, with EMUI 10.1 preload & cust. A ****ty situation but it is what it is. @oslo83 advised me to take the device to Huawei repair center (it's still under warranty) and that's what I'm going to do.
However if anyone has a bricked P40 Pro, I still recommend oslo83 services, there's a chance your brick is different from mine and that he will be able to unbrick it. If not, he will issue a refund like he did for me.

Hi guys, I have a brilliant update for you guys:
The guy I was working on this issue was able to fix my phone remotely with SigmaKey. After hours of tries he made it!
There is no software solution yet - so the back cover has to be dissembled. I went to a phone shop at the corner and let them open it. After removing ca. 10 screws you can reach the "Test Point". There are some videos on YouTube which can support you. Its not easy but its makable.
The genius guy gives a step by step instruction what to do via WhatsApp.
So at the end my P40Pro+ works again and I am so happy! I will start the downgrade now (to install gms)and I will DEFINITELY use the correct FW this time
I can share the contact - send me a private message.

Another update hopefully the next one will be the FINAL one.
So like @oslo83 suggested, I contacted Huawei via chat on their official site. They accepted to repair my device for free with no problem. I sent my phone to the repair center and now I simply have to wait. The person in the Huawei chat told me it could take up to two weeks. And another thing, they let me know the phone will be updated to the latest firmware, so I probably won't be able to downgrade and install GMS, unless there is a way to install it on EMUI 11 (not sure). But at least I'll have a working P40 Pro again

I have the same problem. I'm tryingto fix it with hsuite proxy and the phone in fastboot&rescue mod

Preload version: ELS-N29-PRELOAD 10.1.0.2(C432R5)
Checked "Recovery OS", CUST PKG and Preloaded PKG
So far it connects
I can download and unpack the firmware on the phone
but then I have an error-message on (Installing 0%) telling me, that on this phone the recovery mode is not available. I'm trying with different base firmware - but every attempt takes a lot of time.

How to update phone after downgrading from EMUI 11 to 10?

So, I downgraded my P40 Pro from the latest version to EMUI 10.1.0.121 to install Google Apps. Now I can't update the phone back to EMUI 11 using Config>System Update. I don't know that much about this stuff.
My computer is not recognizing my P40 Pro, it only charges the phone. Super Fast Charging is working.
My model is ELX-NX9 (ELX-N29 in phone's box). I used Hisuite and proxy to downgrade. Everything is working in the phone. I only did one thing that I guess I'm not proud of. I changed my region from C605 to C452 (I guess that's it. It's the European version, and I live in south America). I only did this because I couldn't find a C605 ROM in the website I used. Actually there was one with version 10.1.0.180 or something, and it couldn't install Google Apps.
Can anyone give me some light about it? I want to know if I can get it all working, now the only thing bothering me is the updates and the USB. And the "Custom Version" in the phone info that reads "CUSTC605D1"

Wow. Nice! It is not so easy to repair that. Maybe you will need a NM card if your phone doesn't recognize OTG.
You need a DLOAD firmware (ELS-N04_10.1.0.123(C605)_[ELS-N04_hw_la_R2])
(ELS-N29 10.1.0.123(C605))
and write it.
Is your phone N04?

When I try to update through power button + volume up and erecovery it gives me this message "getting package info failed"

Flashed P40 Pro not working USB on EMUI 12

I bought a second hand ELS-N29 that is on EMUI 12 and the previous owner told me they flashed it. I noticed that vibration is weak except the indicator that you've reached the maximum/minimum volume, in that case the vibration strength is normal, and USB connection isn't recognized on either PC or phone and SuperCharge isn't working. When I put my phone in fastboot mode, however, the PC recognizes it and when I enter system recovery on HiSuite while the phone is in fastboot, the phone recognizes that I've entered recovery mode. So I'm thinking it's a software issue and not a hardware issue. Is there anyone that can help me with this? eRecovery didn't help. I can't seem to find C185 full OTA anywhere on the internet to try dload (I have an NM card).

If reset to factoy settings doesnt help you, it should be a hardware issue. Also be sure that you use an original USB cable + original 40W charger to have fast charging.
You also be sure that you have installed HiSuite on computer.

When in fastboot mode, the PC recognizes that there's a device connected in recovery mode and the phone does the same so I don't think it's hardware. Failure for that recognition when the phone is powered up is why I think it's a software issue. So I want to flash a full ota or any other means people might suggest here because I can't seem to find firmware for my region.

greetings.
Btw could you help as i've flashed with 102.0.0.325, thinking its harmony OS as firmware database state.
But its just an ordinary EMUI 12 that i can't downgrade through HIsuite / proxy / dload.
Help appriciated.
During DLOAD i get verification error, HiSuite gives me package error.

I don't know what phone do you have, what firmware is on it now or was before you upgraded. A screenshot of About phone is needed.

The simultaneous loss of usb2.0 transfer and Huawei fast charging is a sign of triggering anti-rollback. Usually it is caused by downgrading from a version released after fixing the checkmate 30 vulnerability. Just wireless OTA upgrade to fix it， or you can purchase an harmony tp cable to restore USB 2.0 tranfer, or using a USB 3.0 cable connected to USB 3.0 port to transfer data.
