Hi,
You can use this link to download the rollback package
http://download-c.huawei.com/download/downloadCenter?downloadId=91623&version=357533&siteCode=se
once you download it.
unzip and put the update.app in the dload folder on your external sdcard in your phone.
you have to manually create this folder in your external sdcard.
once you do this
type
*#*#2846579#*#* in your phone dialer
then you will get a menu
in that select
SD card upgrade
then you wait.
it will reboot and finish rolling back to stock.
Remember this will get you back to stock rom, but you will have to upgrade to some other ROM for your L09 after rolling back.
I do not have Huawei P9 but I have Huawei Mate 8 & Huawei Mediapad M3. I feel that there are lot of similarities between Huawei phones & that is why I feel you can make it work using these steps.
Hope this solves your problem.
For updating to EMUI 5.0
you can use firmware finder from play store.
Install the app
https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder
in the settings of this firmware finder app
switch on "add on proxy"
now go to your WIFI-settings
tap and hold your WIFI connection
modify network - select manual
there you put the following
proxy is
localhost
port is
8080
that's it save.
then go to firmware finder app
search
download the right firmware for your P9 L09 and then click on "send the firmware to updater"
now
go to settings
update -> you should see the OTA for EMUI 5.0
But don't this now. First you have to rollback and only after that go for this EMUI 5.0 update.
Don't forget. Please click on :good::good::good::good::good::good::good::good:

Cannot update from EVA-L09C432B182 to Nougat
Can anyone please help. I'm going round in circles, following guide after guide.
I'm currently running a P9 L09, running EVA-L09C432B182, after rollback
PHONE Unlocked
FRP Unlock
Factory Recovery
I've tried the firmware finder, confirming firmware ok with IMEI. My version for some reason does not have the "send the firmware to updater", and I have configured the proxy, and installed the proxy. I've tried unzipping the downloaded update.zip by firmware finder, and dropping it into the dload folder.
It seems every version I try, its fails at 5%. What am I doing wrong.
Can anyone tell me a system that works to get back to the latest stock nougat.

b329 update and no music app

Hi everybody) A few days ago i updated my branded(vodafone) mate s to CRR-L09C02B329(MM) version, during update i had a fail message and when I restart the phone I found out that the update was installed successfully, but there music app was not installed so now I can't open mp3 files on my Mate S.. If someone else have had the same issue, how you solve it? Can I make downgrade the phone to my stock android 5.1 version by downloading the firmware from officila hghuawei site? I know that I cant flash c432 versions because it's not vodafone... Maby someone has the vodafone 5.1 firmware in this case, I would ask you to share the link with me) Thanks in advance for all xda audience))

Do a hard reset to see if this solves the problem. To find all the available roms for your version download the app firmware finder from play store.
For rollback to 5.1 see here https://forum.xda-developers.com/showthread.php?p=66710428

C900 is global firmware and the procedure is the same for all versions. You can flash this and then flash a 5.1 rom with C02. The file has instructions on how to do the rollback.

zan. Thanks for your help) Probably I will do this procedure but wanted to ask you: I found a full (and not OTA) verssion of the same firmware wich I have now CRR-L09C02B329(MM) Can I restart update procedure by dload? Maby the full firmware will fix that bugs..

Yes, you can. Probably this will solve the problem. I suggest you to use the installation method with the three buttons so that to do a clean install. Note that with this method you will lose your data, so make a back-up.

So the firmware size was 3Gb, yes I have already tried two procedures with three buttons and from menu by by digitting code #*#*2846579#*#* and selecting software update but nothing changes, yesterday I also looked for lollipop vodafone version, but I could not find anything.. I thought about flash role back c900 from official site and then retry to flash the same Marshmallow version... Can I do that?

I have already seen all roms of firmware finder but there are all OTA versions, and only c02b329 (which is my current version) is FULL. Is it illegal to flash current version over c900?
I have tried to install rollback and then once again c02b329... But after install rollback I didn't have c900b300 as axpected, but still have c02b329 and then reflash same version has no effect) But yesterday I found c02b110 which is an official firmware(lollipop) of vodafone, (if somebody else would need this firmware I will share a link) Can I try to flash this lollipop version just over my current firmware?

[Help needed!] L09C635B361 can't update via either OTA or TWRP.

Hi guys, I am only a very junior user who randomly flash his phone but most of the time I want my phone to be stable for work. I have had the situation since the recent OTA available, suffered a lot, would like to seek any help or advice.
I have a L09C635B361, Japan version. I updated to Android 7 via OTA, then unlocked / rooted under the instructions in this forum, forgot which exact thread though. Never thought of flashing any customized rom so I haven't realized the update problem until the recent OTA update (from B361 to B382) released. I got the push, downloaded B382 OTA package, restart to TWRP, then the flash was failed in TWRP screen. Restart again, the system notified there was a recent update failure. Then I installed Firmware Finder, downloaded the 3 update zip files, restart back to TWRP, still failed installing. Please refer to the failure screenshot for detailed reson. I have no idea what it said and how I should do differently.
No other way to go, I backed up my system, then wiped my phone, reset to factory mode, but brand new system was very strange: only voice input, no keyboard, missing several key functions such as camera. So I have to restore to my previous system, everything worked well except I can't open "clock".
Right now I am looking at system notification of B382 all the time, but I can't figure out how to get it updated, I don't mind if there's a way enables me go back to stock rom, but it's really hard to find the stock firmware for C635......
Thanks, appreciate your help in advance.

Hey man, try follow this guide to debrand your phone (get onto C432). It will probably unroot you and get you back to stock firmware as well.
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
Might want to check around first though, I dont want you bricking your phone on my account.
Good luck

Thanks bro. I will try the entire process when I have a backup phone.

One more thing is when I first tried to wipe phone, failed for several times. Plus the TWRP flashing error, I have suspect that there's something wrong with my partition information or format error. Can anyone help me to eliminate the possibility by the screenshot please?

On the other hand, I found 3 zip files on Firmware for same version update. Which one should I flash? If I need to flash all of the 3, is there a sequence?

The screenshot for the 3 zip files.

You flash those in the order they appear. Except the last one, don't flash that (I think). From what I know it's always been update.zip and then update_hw.zip.
I see you're going to flash hw_jp which is the Japanese cust, so ignore the advice above about debranding to c432 as that's essentially the same thing as what you are about to do with those files. (C432 is the European version, which is called update_hw_eu.zip)
Also the voice input only bug is well known. You need to rollback to marshmallow (I forget which firmware but there's a thread on it here somewhere) and then OTA back to nougat and it should fix it.

I'm using a rooted huawei p9 Eva l19 on b390 stock firmware. Unfortunately she is sick and her Bluetooth is not working. I read on the net that clearing the cache of the Bluetooth app would help but I can't find the app in settings.
Any suggestions

Rollback to Marshmallow & Again update to Nougat

Great, thanks Rafa Mistry!
I tried to go back to B182, that's Marshallow, failed at 5%.
But I searched a bit and i think we can use the procedure suggested here, Abhisht009.
I don't have the time to try right now, but i will do it tomorrow night, let's hope we will have good working phones soon again.

If you need back to Android use rom from Huawei website and download Android 6 than use method 3 buttons

I dont have time right now to do this but I know how to
You must first download the rollback package for your p9 model from the huawei website
Then download an older version of marshmallow (not B182, use an older one)
First install the stock recovery
Flash the doll back package using dload
Boot up
Flash the marshmallow firmware
Done
You should probably remove the fingerprints before
Tell me if it works

After trying loads of older MM firmwares, which all gave me compatibility errors, i ended up flashing mOOnlight ROM.
Bluetooth is working, all is good now.

VKY L09/L29 C432B162- Service rom

I found link and instruction for upgrade, unbrick, back from custom rom, etc....and I hope that it will be useful for the most people. My recommendation is to use force upgrade method with three buttons. Enjoy!

I used those service roms with same method for p10 lite, p9 lite. I didnt try this one, but, I dont expect any problem because instruction is provided by Huawei. Just, read instruction, but again my recommendation is force method. Because, normal upgrade is not necessary with this rom, ota, or ffinder are more efficient. But if someone bricked phone, or has custom rom, this is the best thing for rollback to stock rom. The reason why to use forced method iis simple, because with three buttons first flash stock recovery and than stock recovery automaticly repair all system and upgrade all things.

No, no this rom is not for rollback. Only if you have issues with Nougat mentioned servise rom is usefull. But if You try rollback from Emui 8 with this yiu can brick phone. For rollback from Emui 8 to Emui 5 must use official rollback from ffinder.

How did you brick phone on Emui 8? Only solution is to try to unlock bootloader in fasrboot and downgrade using twrp, hwota. Method for rollback you can find here in our section. https://forum.xda-developers.com/p10-plus/development/downgrade-p10-plus-oreo-to-nougat-t3724382

Long story. Three days was trying to get it unbricked, even it was in service shop, but they didn't do much
however, upgrade from nougat to oreo didn't went well at first. Almost an hour it was installing oreo update zip file in twrp, so I had to turn off the mobile phone in middle of process. At last, it booted to Oreo, but after a first restart (changed overall appearance from large to medium), it just bootlooped. As I had nandroid backup of nougat in twrp, I tried to restore to that, and my problems just got bigger. I tried to go back to oreo again, multile times, different builds, but no luck. Than I found the method you linked, and with great help of guys from Telegram group, it booted again in OS. Hell yes
Strange thing that happend that it didn't booted to Nougat, but in Oreo acctually. Probably LowLevel format helped to fix partitions and stuff, after that bootloader was unlocked again, As for now I have bad Oreo version (8.0.0.046) will rollback again to Nougat.

I'm try to download but on half its stoped

Hi all I used this service rom and it got my phone working again but there are problems the dialer and contacts apps do not work anymore I had to Install 3rd party apps and software update is gone the project menu won't come up when you key in *#*#2846579#*#* command. Fastboot won't let me install twrp fastboot screen shows bootloader unlocked. Frp unlock As it stands I'm stuck with a working limited phone. Does anyone have any ideas I could try

The instructions on this forum are written very garbled and not clear enough for me to take a chance and upgrade my phone from Nougat to OREO.

I agree with you all instruction for p10 plus make confusion. You can try this to upgrade to Oreo https://forum.xda-developers.com/p10-plus/how-to/huawei-p10-plus-debrand-rebrand-update-t3715288
But, you have stock emui 5 or some custom rom? Im asking because if you had stock rom you had to get regular Ota to emui 8. If you have custom just try to.use Hwota method from mentioned link. I have similar procedure with Hwota for p10 lite so it could be usefull in your case just as example to see how it works

If you have stock firmware emui 5, stock recovery and locked bootloader you can try Ffinder for upgrade too.

Thank you for your reply. First reply from Huawei contributors. Thank you.
I have stock EMUI v5.10 and Android v7.0.
I unlocked the device, installed TWRP and rooted it.
I would like to upgrade to OREO and was hoping to find a solution that will allow me to upgrade using TWRP as it is working and installed.
Please advise.
Thank you once again.
