I am in C432B126 rom and I tryed the update B138 from huawei firmware finder however only the Android security patch was updated. A minutes before, I got C432B156 update by the system updater but the software cannot be updated, I see the "software installed failed" error. What should I do?

Edit: Dear friends, I have successfully updated after the long roads. Now let me give you the dimension to me with this problem just like me. First of all I wanted to upgrade my device to the B138 rom which is stopped the delivery, on the C432B126 rom . I try to update with Huawei Frimware Finder , however; only updated Android security patch (1 December 2016) .I continued to use it later. After that, I received the B156 OTA update automaticlly but, the error "I can not install the software" in% 1 when installaing the B156 OTA update . Then my phone gave me the Error which is in the picture. When the phone was reboot, it was lost in the update. Then my wifi connection is stopped accessing the internet. But when I tried to restart the device for the connect wifi stabil. And when I closed it, I got the error that I see again. I downloaded the Firmware Finder the B156 (full) rom with the advice of people in Forum Xda. I got the "authentication failed" error.Then I try to install the B126 (full) ROM by firmware finder. It was successfully updated and the Android security patch was on the date of November 1, 2016 again. B156 OTA update came and updated successfully. I hope my expreince help the other person who are see the this error in same issues..

Just successfully installed LON-L29C636B156 (Mate 9 Pro taiwan region) with the method described. Device bought on ebay in USA, so no official updates available otherwise. No Huawei ID used/required. 156 Update did not show up in system update without this trick! Very nice!

Still no daydream support in the system *sob*. Oh well, at least i am confident i can upgrade later if Huawei would ever include it - as promised...
[Huawei Mate 9 Guides, News, & Discussion] storm00:
Update successfully to B156. I used the procedure from this thread with FF but I selected for update the OTA with 408 MB. The huawei mate 9 model is L29-432C.

Were you rooted before?

I'm trying it as well but install fails at 24% or something like that.

I was rooted but flashed the stock recovery and boot.img.

Anyone with a solution?
[Huawei Mate 9 Guides, News, & Discussion] Ing.King:
try full b126 via FF then you should get ota for b156 automatically, if not then ff ota to b156.
[Huawei Mate 9 Guides, News, & Discussion] storm00:
No, it is not rooted or unlocked bootloader. Stock rom B138 was before.

Dear -Sniper-!

I have the same situation as you described (same red error message on start).But since i don't have an update option in system setting (as you was too) i can't install-update FW with FF and system update.It must use only dload folder, and it don't work on Mate9.I was already trying B138, B126...How do you manega to install B126 with FF, if you was loosing update funktion in system?With dload folder it don't work...

Thank you!!!
[Huawei Mate 9 Guides, News, & Discussion] storm00:
From the procedure described in this thread to update dialog you should use the 3 dots meniu from up right corner and choose to download the most recent version of rom.
[Huawei Mate 9 Guides, News, & Discussion] ValVK:
Thank you storm00!

I was doing that,only i don't have a menu item "update" (for whatever reason-that is problem).And updates from dload folder don't work on Mate9 (with FF as well).

Can any one which one should i download?

Because it sounds reasonable to download OTA not Full. Also some one mentioned that he managed to get it this way.

Any suggestions?

Full should be around 2.2. GB and ota 500 mb
[Huawei Mate 9 Guides, News, & Discussion] MechanteMiette:
Same problem here : validation of OTA and FULL B156 updates (or B176) failed. Huawei ****ed up their system of validation, it took weeks or months to validate a single OTA update. I'm very (very) disappointed since i hoped i could, for once, use a smartphone without being forced to root it …
[Huawei Mate 9 Guides, News, & Discussion] -Sniper-:
They choose full rom 2.2 gb, but system updater download 2.2 gb and start download another 2.2gb. So in total 4.5 fb rom is downloading.

on my MHA-L09C34B122, I chose MHA-L09432, had teh option to download the 2.1 GB update.

It downloaded 2.1Gb, then said that it had to re download and downloaded an extra 1.7Gb

it then did the restart and was updating it with a black screen and then said the update failed.

after it restarted I no longer have an update option in settings.

Any clues/help on how I would update the phone?

and would it involve a full wipe?

I thought I read that a new update just dropped for the regular mate 9, so hoping it will be out soon for the mate 9 pro..

[Huawei Mate 9 Guides, News, & Discussion] jr313:
No you don't have to be rooted, did you check the system update in your phone settings after you tapped download? That is where it would send it, and it should show up there if it worked. Tap the update and your phone/erecover will take over from there.

Edit: Even updated to MHA-L29C636B172 !

I went from L29c636b110 to L29c636b158

I used the second full OTA by the way
[Huawei Mate 9 Guides, News, & Discussion] Peppus:
Hi kartalgurhan, how did you do that?? I'm with the C636B158, I tried the first and the second ones and always got an error after the download. Which one did you use? Did you have the bootloader closed? Thanks!
[Huawei Mate 9 Guides, News, & Discussion] kartalgurhan:
Hi,

I just followed OP's instructions. Yes, I used the second full OTA and worked.

I had a locked bootloader.
[Huawei Mate 9 Guides, News, & Discussion] duraaraa:
You're not doing anything wrong. It's just that Huawei isn't authenticating it for your device.

Is your phone rebranded? Especially if you rebranded L09 to L29, that could be the reason.

C636B172 is not being pushed out for all devices. Whether or not you are authenticated depends on the details of your device, and on Huawei's policy of authenticating the update. In the future they might decide to allow install on all devices, they might not. So far, they have opened most of the updates, but not all, to all devices, eventually. But based on what I can tell, they might be getting more strict about rebranded or out-of-region devices.
[Huawei Mate 9 Guides, News, & Discussion] Peppus:
Hi, I locked the bootloader again and tried the only B172 Full-Ota you can see in my previous image, the first one, and failed again. Please could you make a screenshot of the one you successfully used? Thanks!

---------- Post added at 09:58 AM ---------- Previous post was at 09:50 AM ----------

Hi, I'm sorry, I didn't see your post before. Yes I come from a L09C40 rebranded to a L29C636 , this should be the problem. It is surprising that you can update to the B158 directly from the system update but not the B172 throwing it to system update by Firmware Finder. Thank you very much for the information!

By the way, if anybody in my case get into the B172 let us know, please!

After download 2,5g in about 7 hours with out sleep (Mate 9 C636B172) when finished download it prompt me that there is a new download 2,5g (the same version) and my download counter goes automatically to 50% with out letting me do anything except wait other 7 hours to download... So i delete ff program, ff proxi, clear update app to stop showing the update....

Does this has to do because when start downloading i didnt remove from my wifi connection the proxy settings so when finished always search and find new firmwares?

But now there are 2,5g (from the first download) somewhere in my device....

How can i find them and delete them?

Why this problem with double download happens?

EDIT: OK now I'm on B172... That was it... After stock update app find the new firmware you always have to go to wifi connection and remove proxi (return to automatic mode)

That means that after download FF won't search or find the same or new firmware for download...
[Huawei Mate 9 Guides, News, & Discussion] Ing.King:
you have to change proxy right after download starts. Then you will not get double download...
[Huawei Mate 9 Guides, News, & Discussion] monkeygod:
I think the latest version of Firmware Finder format is completely different from the one in the OP. I am not seeing any of the listed options. In fact there's only three choices, Delete HWFF Folder, Use proxy for install, and Show packages for current region. Is there a hidden menu or something I need to look for? Also the proxy tool is now an add-on but for some reason it is not recognized by FF as every time I click on setting, it keep asking to download the tool over again.

Edit: Ok manage to download the 180 build but failed at the verification stage. Will try 172 now.

Backup everything what you want

Install Firmware Finder and point B158 to system update. Do wipes after flashing to clear user data from newest data chunks

P.s. Use FullOTA-MF only
[Huawei Mate 9 Guides, News, & Discussion] te36:
So i wonder:

Firmware finder was showing me LON-L29C636B182 since a couple of days. And i tried to upgrade to it at least twice every day. But it always failed authentication. Today i saw that there is an upgrade of firmware finder. I installed it, tried again to upgrade to B182, and e voila. It worked.

So, is this coincidence ? Aka: Huawei just happened to authenticate the image today ? Or do new versions of firmware finder do something to help that ?
[Huawei Mate 9 Guides, News, & Discussion] Leighm0:
Going to say coincidence, I just tried and I still get Authentication failed, and I'm using the latest version of Firmware Finder...
[Huawei Mate 9 Guides, News, & Discussion] jodvova:
Same here. Just tried latest version and got authentication error on 180. Tried like 5 times full ota.
[Huawei Mate 9 Guides, News, & Discussion] duraaraa:
Because Huawei isn't authorizing for your device, but authorized for another person's device. It depends on Huawei's arbitrary rollout pattern. The phone gives its device ID and various information about it to Huawei's server, and Huawei determines whether or not to allow the update.
[Huawei Mate 9 Guides, News, & Discussion] Leighm0:
Thanks.. believe you told us about this before - was just letting them know it is a coincidence and that not everyone is Authorized now :)
[Huawei Mate 9 Guides, News, & Discussion] jodvova:
Im having hard time believing in this explanation.

My device is original L29C636B158. I saw many people on L29C636 installing B172 and higher without any problems.
[Huawei Mate 9 Guides, News, & Discussion] duraaraa:
You may have a hard time believing this explanation, but it's 100% correct. Consider that this is coming from someone whose business hinges on having a thorough understanding of Huawei's update mechanisms.
[Huawei Mate 9 Guides, News, & Discussion] jodvova:
So how do they authorize on per device basis? Using IMEI?
[Huawei Mate 9 Guides, News, & Discussion] duraaraa:
Without being too specific, they send pretty much all of the information they can to their server. Your vendor (looks like "MHA-L29-hw-spcseas"), your device ID (64 bytes of hex data), an encrypted set with IMEI/IMSI information, the version you're trying to install, a one-time install token, and some other things.

Anyway, I'm sure your device will eventually get the rollout. Unfortunately, it's stuck behind other people's devices. It's just a matter of luck.

Mine says null too and I'm stock L29C636 on B156 firmware and never used custom recovery / root.
[Huawei Mate 9 Guides, News, & Discussion] systemik:
Hello

I’ve an issue with my L29C432. I’m not able to install any firmware update.

On day one, I’ve used the root method on my device (on firmware B138). After installation, my device proposed me with B156 update but I’ve never been able to install it.

Here is what I tried :

Restore recovery and boot to stock version and perform regular OTA. -> No luck with authentication failed message

Use FF to install B156 (and some other versions) -> No luck with authentication failed message

Use eRecovery to install official firmware. No luck with package download failed message

Use FF to reinstall B138 -> Partial success. The firmware installed through eRecovery but a quick error message popped up at 99% of the install. The phone rebooted properly after that and B138 run fine.

What I’ve seen :

The phone did not propose OTA update until I put a SIM in the device.

The FF software state vendor/country “null”

The huawei hidden menu (*#*#2846579#*#*) state proper vendor/country = hw/eu

I’m a bit lost and not sure what is the next step for me.

I’m not willing to use funky huawei yet or to use offline image (dload method) and change by C432 to a C636 … Not sure either about the possibility to do this via the huawei multi tool which is compatible with Mate 9...

Systemic

Update : SOLVED...

Steps :

Reinstall Recovery B138

Use FF to ReInstall B138 FULL (no error this time)

Use regular update to B156

Factory Reset

Redo all steps for Root

Restore data and Apps via Titanium backup
