Downgrading from L09C432B378?

I have Paul O'Brien's stock L09C432B136 ROM which used to serve me well but for sone reason when doing the 3 finger flash it comes up with software incompatibility error.
Does anyone have any ideas as to how to downgrade to marshmallow?

Use the beta rollback downloads from Huawei website

More info?

I must reinterate I've successfully upgraded via b136 to nougat but I thought that a full stock ROM is able to "take over" and completely flash stock ROM.

I was on Eva-l09c432b178 and i have downloaded the rollback package for Europe and now my phone shows Eva-c900b300 (intermediate firmware)
After this i am still trying c432b136 full firmware, c432b182 as well on sd card dload via 3 button method, but i am stuck at 5% and fail. which firmware i should go for ?

I would use the firmware listed with the rollback package, I believe they are paired for the fact the work together. In my case for the UK the rollback package was paired with b166. Worked perfectly for me. Then you can apply b132,

still no luck with the c432b166 firmware provided in the link, i was on c432b378, i followed the instructions of rollback and now my fone show c900b300 but after that i am unable to apply EVA-L09C432B166, its stucks on 5% and fails, then fone shows message to restart.

I got stuck on B300. What I did was use SRK tool to install TWRP & use that all wipe B300. With no OS I then used SRK tool to reinstall MM recovery. From there I installed the Paul O'Brien B136 from dload. If you are confident your B166 is good you might want to try that.

Problem solved, i was transferring the update.app files via data cable and i was getting errors, i just used a card reader and transferred the dload folder to sdcard and it was all ok. its strange but worked for me. now i am on c432b182

P9 Bricked (Fastboot, force upgrade not working)

Hey guys so I have a problem.
Tried to upgrade to the Nougat EMUI 5 from EMUI 4.1 on my P9. It installed but it had no camera and no keyboard installed. So I tried to do a factory reset, I did but now I'm stuck in the set up wizard, and can't even complete it because no keyboard (google voice in its place) and if I try to skip step that need input and go to the end it just loops from the beginning.
Next step I took a stock rom of 4.1 and placed it in my external SD card in dload folder and tried to do a force upgrade but no help. It immediately shows 5% and it fails with no error just a red exclamation mark. So next I tried to use fastboot to flash it but get errors saying remote command not allowed (I have HiSuite installed, but the phone doesn't show when I run 'adb devices').
Factory reset fails, erecovery fails to download anything, can't system recover with hisuite as it fails. But when I try it, the fastboot screen on the phone say 'rescue mode entered' so it's being detected.
I'm at my wits end here on how to get it back. Screw latest android, just want to use the phone. Also does this break warranty? I didn't root it or anything but installing unsupported software could be considered warranty void?
Thank you for help in advance

I believe your warranty is still valid since you havent unlocked the bootloader. After upgrading to Nougat you should have downloaded the rollback package from huawei`s page, since you cannot simply go from Nougat back to Marshmallow ( you need to flash two files, first being "an intermediate package", and second one being marshmallow update.app file, both of which can be downloaded from huawei`s official site ). Try this and see if it helps

Thanks for the reply, now I know for the future.
In the mean time I fixed it with DC phoenix tool. Although now I have a problem as it set it to C900 so lock screen doesnt update, themes and icons dont work. All issues i can live but would like to fix them. All I know is that I have to unlocka the bootloader, install TWRP, install the version I want with hw and dt folders, and reboot. But everyone on forums speak like you know how to do it and can't find a good guide on how to do it.

You`re welcome. DC Phoenix is good, but you have to pay in order to use it, right ? That`s my problem, I cant pay since all my money comes from my dad . In your case I would probably try to update via huawei updater and HiSuite. As far as I`ve seen, that method has been most reliable for the majority of users.

I dont know how much research you have done or what you have tried exactly but it sounds like you have made matters worse. I was in your situation before but was able to get past the setup wizard without a keyboard, after this I got ADB working and just installed a keyboard APK.
C900 means you have a cross flashed rom, this can cause all sorts of different issues and I believe when it comes to updates, C900 either gets no updates at all or be the very last in line to get updates. Also, being on C900 could void your warranty.

DC Phoenix worked for me, I found myself in the same position as you (no dload, reocvery, e-recovery only fastboot) and thought my phone was unrecoverable for good. Tried every method possible. in the end bit the bullet paid the fee for DC Phoenix had my phone running in 20 minutes.
Hopefully some smart cookies can develop some freeware that works the same way.

I fixed it by using DC Phoenix to flash the B163 stock ROM but got the C900 firmware due to cross flashing. I fixed it by unlocking my bootloader, installing TWRP and rooting it. Then I just flashed the C432 OEMINFO, reboot and immidietaly got a notification that an available update is ready to be downloaded (B182). Downloaded it, installed no problem and now I'm on L09C432B182, which is what I wanted, minus all bloatware from my provider (Vodafone)
All done with SRK Tool (in the utilities menu it has for OEM fixing and even the themes not working by flashing the hw_init folders).
Overall, got it running and everything fixed

Awesome, good to hear. I highly recommend you upgrade to Nougat (but make sure your camera app and keyboard app is installed and working). You should be able to do this by using HiSuite and Updater 2.0.

In the same situation

First of all, get your bootloader unlock code. To get it google how to get it (I cant post link as I don't have enough posts to have privileges). If you can't on the English, make a new account on the chinese emui page and use google translate in chrome to navigate. (if the padlock button doesnt give you a form to fill out, clear your cache and cookies or open in incognito mode)
Once you have the code, find the "SRK Tool Huawei Bootloader/ROOT/Recovery/Backup/Utility" thread on XDA and download the latest stable build, should be around 700mb. Also in the thread, the guy posted a video on how to do it.
Step 1: Unlock bootloader
Step 2: install TWRP Recovery
Step 3: Root
These 3 steps are in the video.
Once you successfully rooted, open the tool again and in the Utilities menu (7) there is an option to flash OEMInfo. Select that and choose the OEM info you want. I needed C432. It will use the superuser app to flash it, reboot and you should be on it.
If you are asking how to use DC-Phoenix, again they have both written as well as a video with instructions on how to do it. You don't need an unlocked bootloader as it will use an exploit to circumvent it. Do Method 1, if it doesn't work, do Method 2.
Good luck mate

I got into this mess in the first place by flashing the B361 and my camera and keyboard didnt work after upgrading it. But now that i know how to fix it, I might give it a shot. Is there a thread with features and testing of the Nougat emui 5 for P9? I saw a lot of threads of people rolling back due to battery issues and other stuff. Don't want to update if its not the best.

Thanks

VIE-C900B160 there is no update

Hello I have Huawei P9 Plus and Im still on Android 6.0.
Everyday i check fpr update and there is no signs for it..
My build number is VIE-C900B160
And my model is VIE-L09.. plese help me get Android 7.0!! Cheers

Hello same problem for me. Have you found a way to update?

C900 does not recive OTA, u need to debrand to C432.
https://forum.xda-developers.com/p9-plus/how-to/vdo-guide-how-to-debrand-huawei-phone-t3410046
Sent from my VIE-L29 using XDA Labs

Use firmware finder and upgrade to the last FULL version (not OTA). Mine is VIE-L09C900B181. It was possible installing the FULL C432 version (no root just upgrade).

Hello and thank you so much for your help.
- I tried to download a firmware manually and put files on dload folder but when i restart it says it's not a compatible update.
- Before i tried with firmware finder but, i don't know why, i hit download but nothing happens. stuck on 0%. (i configured the proxy in the right way etc...)
Now i'm gonna try to follow the video guide. Honestly i'd avoid to root the device but i have no choice.

Open Firware Finder, select Change Model and set VIE-L09C432.
Select Get Firmware List and then VIE-L09C432B180 Type: FULL Size: 1,616 GB
Download it, check it unpack and move to Dlod
No root needed !

Thanks for your help but it was too late.
Tonight i followed the -first part- of the videoguide (Mostar088's link). I mean i unlocked the phone, installed twrp, root the phone and at last i debranded the phone with srk tool.
After the reboot, i noticed there was an update! so after the update i had my super cool brand new Nougat! but it's not a big deal at all! -_-
some serious and odd things:
- i had NO KEYBOARD just google dictation. i had to fight trying to dictate my google account credentials. But i did it and i installed a keyboard.
- NO BLUETOOTH. i can't activate it. i try to toggle it on but nothing happens.
- XTREME BATTERY DRAIN.
- UPDATER option doesn't work. i tap on it but nothing happens.
Can you help me? I don't know what to do. i think i got the last ota update but it doesn't work.
Thank you!

I did it now it works!
Downgraded to Marshmallow and updated again.

Follow the first part of mostar88 linked guide.
You need to "debrand" to C432. Before debranding you have to root the device. So unlock the bootloader, install twrp, root the device and debrand.
After that just reboot and install the ota update (check for updates). In this way u gonna lose root mode and twrp recovery.

try to follow this steps

Can someone give me some more feedback about these steps? I open Firmware Finder, changed the model and looked up that exact version in the list, full size 1.6gb. I hit download and I let it download (took a few hours), then, the download finished.. but what do I do now? There's no message from Firmware Finder.. the step "check it unpack" .. where do I do this? And "move to Dlod"? What is dlod? A new app?
This is so confusing, lol.

Problems after 7.0 flash

Flashed 7.0 with TWRP and now i have no camera, keyboard, or any other standard apps.
I found a thread describing a fix, however it was not for my model.
My device is EVA-L19
Was on EVA-L19C185B220 and updated to EVA-L19C185B360
Can some ELI5. I've been using custom ROM since my HTC HERO. I really don't understand why it's so different and complex with Huawei devices. I, for some reason, can grasp the logic on their location based Roms/restrictions etc.

Turn back to marshmallow using rollback file and official L19C185B180. After that, update phone to c185b320 beta using huawei updater. Then you gonna get b361 ota notification
---------- Post added at 12:53 AM ---------- Previous post was at 12:51 AM ----------
Dont forget to do wipe and factory reset from erecovery after updating b361. You will have full stock nougat.

I have locked bootloader and nonrooted device, stock recovery too.
Can anyone help me?

Thank you for answer. When i flashed b182 update(dload method) after that phone did factory reset, and after that power on.
Do i need to factory reset again? When i installed b182 in my folder dload was only update.app(3.22gb), do i need to have other files in dload folder or just update.app? i missing stock apps like compass, mirror... Maybe i need to flash some data files but i don`t know how without root or bootloader, and i would like to not root my device. What to do?

Here is an excellent guide for Rollback, I followed two times and everything worked perfect. However, skip 7-8 there is no such package and for 9 you should receive OTAs b383, b386 and b393 (some also get b393)

Hmm i followed just like that and i have update now to b383 but i won`t bcs i wanted mm. Weird, i found on forum that i need to flash hw_init with srk tool if i miss themes but that need a root. Hw_init is file from update_data_full_hw_eu(Step 7-8) but i don`t know how to flash it in dload bcs there have only files in zip not update.app.I think i can`t flash zip file in dload. I searched that zip (hw_eu) and i found hw_init file and also my missing apps like compass. How to flash this zip without root?
