Accidentally upgraded to nougat and I just need to return to stock 182 and I don't mind factory wiping the whole OS. Better if you can tell me the best way without MicroSD Card thanks . I have already tried installing TWRP but doesn't work on Nougat? I'm still incredibly new and spend the whole day trying to reset my phone :/
How did you update to Nougat "Accidentally" when it's not official? Did you tried with the Rollback package provided by Huawei?
Well I downloaded the wrong firmware and ran it through TWRP and it upgraded to nougat. Point is I don't really understand the rollback because I'm new to this if someone could either help me with the steps and provide another way like wiping the whole internal storage and installing a fresh OS
Main problem is not having a microSD card ATM so I'm mainly thinking to wipe the whole O's of and reinstalling it which seems easy if I could get TWRP to work on Nougat

Hello guys.
I recently upgraded from EVA-AL10C00B195 to Nougat Beta B322 It was probably for L29. But after upgrading, there isn't a camera app and google apps do not work. So decided to go back to stock MM rom but I cant install TWRP and root the phone. I have a full TWRP backup of the phone from before upgrade. Is there a TWRP for P9 on Nougat?
I don't mind the data on the phone, is there a way for me to go back to stock rom? Any help would be appreciated. Thanks!
You need to grab a full marshmallow stock rom,unzip it to the dload folder on the external sd card(it should contain an update.app file).
Then hold down both volume keys and power button and it should reflash stock rom and bootloader.
I tried that with EVA-AL10C00B183 FULL rom.
At 5% it gives error:
Software install failed!
Incompatibility with current version.
Please download the correct update package.
Would've been great if it worked this way. Anymore ideas?
It looks like you downloaded an update package and not a full rom

It was a full rom package. Which one do you recommend? I will try that. http://hwmt.ru/oth/HWFF/info/view.php?find_model=EVA-AL

Hmm,Im not sure,it should work.
Try
1.Factory reset of the phone through the main menu and not through twrp.
2.Make sure you have the right rom in the dload folder on the external sd.
3.Make sure you don't have a dload folder and rom anywhere else like the internal memory of the phone.
4.If that fails try relocking the bootloader if it's unlocked and try again.
If that doesn't work then I don't know what it is,maybe try signing up for the beta and see if you can get another update which has a functioning keyboard.
Factory reset fails everytime. But when the phone boots up, the settings are reset. I don't have twrp after the nougat update.
The rom was in external sd inside dload folder.
There isn't a dload folder anywhere else apart from external sd that contains the stock rom linked.
I've unlocked the bootloader and it's the same result.
Where can i sign up for the beta? I don't think there will be beta for chinese AL10 rom.
Here you are:

Thanks for the help guys but non of this worked for me. I kinda bricked it.
I went ahead and spent a lot of money on DC-Unlocker. It basically formatted the phone and flashed a small factory image. After that, the instruction said I needed to install a full stock firmware for the phone. After which I had to repair the IMEI and also had to get it SIM unlocked even though my phone was factory unlocked.
It costed me 15 euros for formatting and flashing factory firmware. Plus 8 euros to repair IMEI. Plus 4 euros to get SIM unlocked. Total: 27 euros! Now I am back to stock rom with everything stock and working.
Moral of the story, don't install nougat beta if it isn't for your phone. EVA-AL10 in my case. Just wait for your turn.

n0my, please have a look at my thread that I just closed off: http://forum.xda-developers.com/p9/help/issues-twrp-root-access-flashing-t3509877 I had the exact same problem, but I'm all good now!
i cannot find rollback package for eva-al10, this ****ing variant make me mad, goddam huawei, no more phone from this brand from now on.
I have a EVA-L19C185 model phone and I have bugged it out by installing an incorrect version of Nougat or the Beta and getting TESTKEYS in the firmware version now.
I have as such decided to reformat and reintall everything completely.
Can someone advise on the best method? Since I have upgraded to Nougat the TWRP version cant wipe everything i think?
Having persused some of the threads, it seems like I need a method that will reflash my entire boot and system partitions.
Any suggestions of guide would be much appreciated!
Thanks in advance!
Most likely you have to be using C432 cust
Hi.
I'm just wondering if anybody can help me please?
I have a UK Huawei P9 EVA-L09 with Marshmallow currently on it (B166) build I think. It is unlocked and has TWRP 3.0.2.0 Recovery installed on it.
I would like to upgrade to Nougat 7.0 and EMUI 5.0, but most of my attempts have failed and I have had to use the rollback method to get back to Marshmallow.
I have tried to do it by flashing an Update.zip and subsequent EU_Apps package.zip through TWRP to no avail.
I have also tried the 'Dload' folder method, also to no avail. The closest I've gotten is to build no B378, but it shows up as NRD90M Test-Keys on the Build No in the phone settings instead and all apps such as camera, NFC, Bluetooth are missing / not working etc. Trying to then flash the EU_Apps package through 'Dload' method doesn't alleviate the problem of missing apps.
Does anybody have any tips for what I could try to get it onto a working Nougat build with apps please?
Also, if anybody has any links to any relevant firmware etc, then that would be very helpful too.
I'm pulling my hair our trying to get this to work. Surely it's can't be that hard can it??
Many thanks, Bill.
Is your phone branded? For a particular UK network I mean? And if so are you flashing ROMs for that network?
I don't know if that's the problem but I was on Vodafone UK B137 (which is Marshmallow) and flashed the 2 update zips for a Vodafone Nougat ROM thru TWRP and it was successful. I then flashed an updated zip using the "dload method" and that was successful too.
When you say you flashed the zips in TWRP "to no avail", what exactly was the end result?
Also might help if you give the full version of your starting ROM, and what zips you were trying to flash, ie full names and sources.
I'm kinda new to this device forum but seems like people get varying results with different flashing methods, for no particular reason either!
Peace.

Hi. Thanks for your reply.
When I tried to flash .Zips through TWRP it kept coming up with errors and didn't flash them (something about being umnable to mount /System).
I was on EE UK, but found a method yesterday for debranding my phone and setting it to C432. I also managed to successfully flash C432B182 firmware on it.
I have since attempted to flash Nougat B360 using the 'Dload' method and now my phone keeps asking me to enter my password to decrypt storage. Multiple attempts to reset my phone and wipe cache partitian don't seem to be working. Do you have any idea how I can get around this?
It's so hard and it's so annoying how other people seem to be getting it right and mine is proving to be a swine. Makes me want to get rid of it to be honest and get something easier.
Thanks again, Bill.
I'm concerned that this may be bricked right now. No amount of using eRecovery to reset the phone will stop it from going onto the dreaded 'enter password to decrypt storage' screen! I will see if I can re flash it using Fastboot, but I'm a bit concerned right now...
I have an O2 Branded one. I'm too chicken to mess with it in case I brick it!
Just waiting for the official UK O2 OTA update to arrive &

Probably advisable unless you absolutely know what you're doing and don't mind taking the risk. I'm a bit annoyed with Huawei and my carrier, they are always so slow with providing updates and Hmui 5.0 is only what Hmui 4.0 should have been in the first place. I'm done with these manufacturer's stupid over bloated overlays and will be going to an official Google phone in future!
If you can get it into fastboot mode, flash TWRP, then you should be able to progress from there, hopefully by at least formatting data to get rid of the encryption! Sounds like.a royal pita tho to be honest.
When I flashed to Nougat from MM using TWRP I got a bunch of error messages too, but it (eventually) booted up ok....

Hi again all.
Success! I finally managed to crack it.
I downloaded MM Firmware version C432B136 and used Huawei Extractor to extract the Boot.img, Recovery.img and System.img files and was able to boot into Fastboot mode fortunately. I used a Command Prompt to unlock the Bootloader again and flashed each .img file in line.
The phone booted up into the B136 firmware and I was then able to update OTA to B166, but not B182 strangely. So I downloaded a B182 version firmware and placed it in the 'dload' folder of the phone's S.D Card, before forcibly flashing it by holding volume up, volume down and the power button on boot up.
I subsequently used the below link, which showed me how to use Huawei Updater and HiSuite to update to B361 firmware.
https://forum.xda-developers.com/showpost.php?p=70594380&postcount=2
Once on Nougat B361 firmware, my phone's update setting prompted me to update to the latest B378 firmware OTA.
Finally, to achieve Root status I followed the below guide and am now running root with SuperUser and BusyBox installed. I'm happy to report that both Nougat 7.0 and HMUI 5.0 are running smoothly on my phone and all features are working (i.e. Bluetooth, Camera and NFC) and performance and battery life are all noticeably better than ever.
https://forum.xda-developers.com/showpost.php?p=70927601&postcount=456
Be aware that my phone is EVA-L09, so I followed all guides and downloaded all firmware that related to my specific phone model.
Phew! Thanks for all of your help and good luck to those who are attempting to get this working.
Bill.
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.

Well, it ended up with paying 20USD to some "pro"s on taobao.com to unbrick my P9...sigh...am I too old to do this :crying:
Hi guys, I have a OP3 which is running on 3.1.2 Marshmallow.
I always get a notification for system update to 4.5.1. I've tried downloading and installing the update but after the first boot my OP crashes/gets bricked. There is only a Linux penguin logo that appears no matter what button you press.
From there I always have to follow the mega unbrick guide and get my phone back to working with stock recovery and 3.1.2.
I've tried side loading the downloaded file as well.
Then I've tried installing .zip file of 5.0.1 via TWRP, still no luck. it still bricks my phone.
Am comfortable rooting my phone, my bootloader is unlocked. I don't care too much about keeping root after updating my phone to the latest version, I would be grateful to anyone who can point me towards the proper full ROM files of 5.0.1 along with any firmware files that may be required.
And the exact process of when to flash the firmware and with/without which version of TWRP. I am ready to completely wipe and clear data.
in simple words I just want to update from 3.1.2 to 5.0.1. The simple downloading and updateing from the OTA update doesn't work.

I though of running a diagnosis check by dialing *#808# and looked up Charger option, it shows the battery as "itech_3000mah"
is that original?
I had given the phone to repair for water damage to a professional service chain (Not OnePlus, some company here called Yaantra). I've heard from talking to an official repair person of OnePlus that fake batteries are not possible for OnePlus.
The battery works absolutely alright, charges up nicely and I get decent SOT. Can't complain at all.
