Hi, I've got problem with my huawei p9
I really wanted an update to a newer build, so i used firmware finder using app proxy to download it before it will show in system updater. Installation went fine but after all i noticed two things: gps is not working - it shows place where i was two weeks ago as my current location and apps from google play to repair this aren't working - and the second problem is my build number. Instead of EVA-L09C150B385 which this update supposed to bring, it is NRD90M test-keys
And my question is that: Is it possible to reverse the update? And if not is it possible to somehow easily flash stock rom to this phone. The device has stock recovery, locked bootloader and was never rooted (and if possible I would rather prefer to keep it in that state)
I've heard about some method using the sdcard but at the moment i don't have big enough at home, so is there any other way?
Previously I was using LG smartphone and it could easily be fixed using LG flash tool
Is there some kind of similar app for huawei?
I know that google isn't biting and that there were similar threads before, but neither one of them really answers my questions and most of them are more about devices with custom recovery or/and root
I would suggest following the debranding method with downgrading to old Android and then install newer version on top.
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
You will need the bootloader unlock code.
Of course because of unlocking the bootloader, your device will be wiped so make sure you will have a backup of your data
As @edmun says above, I'd rebrand your phone and then update from there. You must get an SD dude, I can't do without mine.
Once rebranded, use the following tool (all instructions are there) to get to the latest version. I got stuck on NDR test keys at the weekend and used this tool to roll-back and update.
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
You can always relock your bootloader and remove root once you've finished.
As far as I remember, if you will follow the "debranding" manual, at the end you will have bootloader locked.
The debranding method does not root the phone, so no need to "un-root" afterwards.
In my opinion, that is the easiest and cleanest way to restore the phone to a clean genuine software
What Newkeebrown suggested is to rebrand the phone to P9 China which will allow you to install Android 8.0 (Oreo).
Unfortunately, at this moment, I can't confirm whether it is a good idea as I am quite too busy to test this method (it would involve of course backup and restore which takes around half a day for me)
Kinda suggesting rebranding to L09C432 because there's more support on here for that version. But yes, definitely gives you the option to jump up to Oreo if you wish. I'm lucky, no backing up for me as all I need is my contacts, synced to Google. I always start fresh after flashing

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.
Good morning all:
I am having a problem with my phone.
The history...
Bought a P9 EVA-L19 in Belgium and it came originally with version B127 (I think).
So, I decided to root it and so I used SRKTool to unlock bootloader, install TWRP and root.
Problems started when I tried to update to a newer ROM.
It lost the original look and some functionalities, like the random imagens in lock screen and some original apps (FM Radio?)
In the meantime I managed to update to B137. The look was ugly but I managed to solve it using Nova Launcher.
Then the phone started giving me the message there was an update to B342 but everything fails.
I tried to reblock bootloader with SRKTool but it fails, I tried to download and install with dload method and fails.
So, I'm stuck with B137.
I even tried to debrand using this method: https://youtu.be/JZVsIKtdgV4
But after the first step "changing oeminfo and custom.bin" I even lost the keyboard so I gave up following the next steps.
So now my phone has a ROM EVA-L19900B137 and I can't find a way of updating to android 7.0 and I can't go back to the original ROM with all the functions.
Tha only thing I haven't tried is an Update using TWRP.
Is there a final release of 7.0 that can be flashed using TWRP?
Or even the original ROM?
(no, I know I am stupid but didn't made a backup before root and updates :crying: )
Thank you so much in, in advance, for your time.
I am not expert in these stuff but when I completely removed my system I installed a rom with different cust after that I got c900 then again I removed system and just installed the old cust "c185" and version b161 and then it worked like a charm even updates are working
your original dload method should be working. Just flash an original firmware with your original cust. This will lock your bootloader and turn your phone to original. You will even get the OTA updates.
After that if there is still no nougat update for your phone, there is 2 option. 1st one is check if there is an update that has the same cust number with your phone and apply it.
If not so, you can do a debranding procedure. Here is the link for it: https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
I managed to fix it.
Just in case someone has the same problem, I used the solutions/methods described on these threads:

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, like the title says. I'd like to flash OK Pie onto my old but still working P9 but after so, so much time i have forgotten everything I did to my phone to get to where I currently am. I've been searching for specifics to my situation but the guide to go from EMUI 8 to OK Pie is complicated enough as it is. If I have to factor in the "back to stock" procedure etc I think my brain would explode xD
So I'm looking for any links, guides, personal help or WHATEVER may help me at least get to chinese OREO 9I think I'm capable of taking it from there)
My current setup:
EVA-L09
Build number: EVA-L09C432B378
EMUI version: 5.0
Android: 7.0
My phone is from Latin America, So IIRC I unbranded it, changed it to cust 432 and flashed the latest (stock) firmware which at the time was B378.
I also have TWRP (the latest one) installed. If I got it right, I THINK I need to go back to stock recovery, flash the latest FW and go to Chinese OREO from there before trying to flash OK Pie, right?
Could somebody please be so kind as to either help me or at least point me to a thread/guide made for idiots such as myself xD that can walk me through the steps of going from my FW to stock recovery and stock latest FW?
I'll manage to get to oreo and custom after that.
I appreciate your help in advance.
Thanks.
EDIT: Forgot to mention that yes. I kept my unlock code so thats no problem
Thanks again!

You will have to install OK Omni Pie for Android 8, not for Android 9 (there is no stock Pie for P9)
If you search for Pie in the given two XDA threads (Search box at top- right on any XDA page), you will find that many people have undergone (and some returned back from OK Pie to stock Oreo) with no problems - but it is important to carefully follow the guides, first for rebranding and installing the Chinese stock Oreo, then to install OK ROM EXACTLY as described on their site (common guide for all OK ROMs and for all Huawei phones when already updated to the stock Oreo)

Hi, thanks for replying. I'm aware of the PROCEDURE not so sure about the "how to".
Thats why I posted. Your post basically told me what I already knew (and talked about in my post)
What I'm looking for is help going from my current TWRP/STOCK/ROOTED FW. Back to full stock so I can start updating the ORIGINAL FW. I can't find any info on how to go back to stock recovery for instance. Do I need a specific recovery for the FW I'm running? Is it generic? Where do I find it? How do I flash it? Where do I get the stock firmware? (Huawei firmaware finder?) Which one do I flash? Does flashing the stock firmware automatically flashes the stock recovery? Things like that. I appreciate you trying to help but I already read and knew the things you linked to. My issue is, like I said: going back to stock before I can follow any guide to go up to oreo.
Thanks anyway!

If rooted by Magisk, there is Uninstall option in Magisk Manager, it will unroot.
Similarly SuperSU had an Unroot/Unistall option.
In both cases you can flaslh back the stock Boot partition but it is cleaner to unroot by using their Uninstall options.
From TWRP or Fastboot you have to flash stock Recovery (corresponding to your current stock Nougat firmware) to revert back from TWRP
Generally, if you download from FirmwareFinder update.zip corresponding to your current stock Nougat (must be from FullOTA-MF or FullOTA-MF-PV), unzip, then by using Huawei Update Extractor, you can extract Boot.img and Recovery.img that you can flash then from Fastboot or from TWRP to go back to stock Boot and to stock Recovery
Once you go back to stock Boot and Recovery, you can boot to eRecovery (switch off, connect to charger, keep pressing Vol+ and boot by Pow) and choose Download latest firmware and recovery
----
But in fact, since you already have TWRP, use the HWOTA method from this post to update to c432b504 or b505:
https://forum.xda-developers.com/showpost.php?p=75787151&postcount=2
You can do the same with HWOTA7 from the corresponding thread I gave you (before you will go to rebrand to AL10c00b399).
In both cases, you have to download three update*.zip files for eg L09c432b504 (must be FullOTA-MF), rename one or two of them as described in the OP posts (be careful, some people have Windows 10 that hides zip extension and they wrongly rename files to have double zip extension and then HWOTA/HWOTA7 scripts cannot find the file and fail to flash resulting with half-brick), put them to DLOAD file on the SD card and follow the guides

Thank you. Thats exactly what I was looking for. I really appreciateyour help.
Btw, no one should have the "hide extensions for known file types" checkbox marked...
Edit: Should I flash the same FW version Im currently using and then update regularly? To prevent any issues? (Cause i noticed there are some rules as to the version jumps that can be made flashing like this...

It must be the same model and cust, c432, but safer if you also apply the same build number (b387 ?)
Once you are back on stock you should start receiving OTA updates (have WiFi and a valid SIM card). Give it some time but check also manually from Settings / System updates.
As mentioned in my previous post, you can also use eRecovery / Install latest fw and recovery (if OTA coming slow), and there is a similar option in HiSuite. You will probably not need to use HWOTA or HWOTA7 to jump from clean stock b386 up to b50x

Hi again. First of all I would like to thank you agaib for your help. You made the process so much sinpler and quixk for me and I do apprexiate it.
Second, I updated to the latest "original" fw for my c432 phone OTA but then had to modify the HWOTA7 procesa so I could dl and install the latest/latest fw (because it wouldnt even register when searching for it) I used huawei fw finder to verify it and dl.
After that I went to chinese Oreo, flashed the network fixes and installed a TINY OTA update which fixed some sexurity issues apparently (thankfully it went Ok cause I THINK flashing OTA in a "converted" phone is a big nono?)
Anyways, I ended up on omni pie (the latest beta whixh is 5.2 I believe) as going AOSP was the whole point of this endeavor.
So far I'm LOVING it. Its such a refreshing thing not having to deal with all the bs OEMs bake into their roms... But Im experiencing a couple of issues as well. Not sure if its the rom, my phone or the android version (particularly my issue with battery life since I was having issues with the duration way before I updates, actually that was one of my motivations for updating since I read that pie had better battery management)
Anyway, my issues are as follow. Hope you can help (once again)
Battery life SUCKS (like really, it went from bad to terrible... Not sure if stock oreo would make it better, or perhaps omni pie needs some optimizations?)
The camera (huawei one, not sure about the aosp) has issues. Multiple issues. The biggest one being that if I try to go from back to front camera the app locks in a black screen and I have to go into the app, delete data, reboot the phone and relaunch it (and that doesnt fix it everytime)
The last issue is with pop messages from apps and/or settings. Sometimes, when installing and app and/or changing aome setting a white popup shows up with ONLY an OK option. I cant read anything on the popup. Everything is white. Not sure if its an issue with the theme (I changed from default to "hell" or something like that) but it is VERY annoying not knowing what youre agreeing to.
Last but not least I have a question about the stock rexovery, factory reset and flashing new versions of omni (if and wheb they come out)
In one of the steps for flashing omni the guide asks to perfomr a factory reset from the stock rom. Thing is, it doesnt work. I mean, when I confirm the factory reset the process starts and approximately at 15% an exclamation sign appears and the process percentage stops working. I can reboot the system and everything works fine (using the phone to post this actually) but Im left with that feeling of not knowing why something failed... You know what I mean? Is that nornal?(the failure to factory reset, not the feeling ) also, does factory wiping the phone removes root access? Or does it only renove magisk manager?
Also, if I ever wabt to update the rom (not change it mind you, but flash the next beta or stable or whatever they come up with) do I need to flash the stock recovery again? (Currently rooted with magisk) or is it a separate partition? (Sinxe I had to modify the ramdisk and not flash a custom recovery) also, will I need to do the whoooole thing again? (Backup everything, restore tk factory etc etc) or is it just like with lineage for exanple where you could flash and updatr and keep your data untouched?
Thanks for EVERYTHING my friend. And I hope you can answer my questions (particularly the ones about battery life and thebfactory reset issue since Im planning on doing one last factory reset before settling with the rom. Just waiting for my new micro sd. The one that will stay in the phone)
Sorry for the typos. Writing this huge post on a phone is a PITA.

Hi again. First of all I would like to thank you agaib for your help. You made the process so much sinpler and quixk for me and I do apprexiate it.
Second, I updated to the latest "original" fw for my c432 phone OTA but then had to modify the HWOTA7 procesa so I could dl and install the latest/latest fw (because it wouldnt even register when searching for it) I used huawei fw finder to verify it and dl.
After that I went to chinese Oreo, flashed the network fixes and installed a TINY OTA update which fixed some sexurity issues apparently (thankfully it went Ok cause I THINK flashing OTA in a "converted" phone is a big nono?)

This small OTA bringing Patch02 over b540 installs even over TWRP (but that was not the case for OTA from eg b535 to b540)
Cannot discuss/compare battery for Omni Pie, since not using Omni
Problem with Camera app does not show on stock Oreo. Even if the app was somehow ported from Huawei, there are maybe problems with integration to Omni.
Various Huawei/Mate models come with different cameras, but there is only one OK Omni ROM (with one Camera app) given to work on all Huawei/Mate models
Btw, somebody else also complained about issues with Camera (and GPS) and decided to go back to stock Oreo.
Similarly, issues you described about black notifications or so must be related to the custom ROM, theme or so.
As a general rule:
- for installing OK ROM, you flash System partition, and nothing else
- you also wipe Data partitiom (containing all your installed apps, incl Magisk Manager, also containing your user settings)
It does not affect any other partition.
Therefore, changes given by NW patch persist - without, you will have (also in that OK ROMs) problems with SIM card(s) and connecting to the network
Also, Magisk, which was flashed to Ramdisk, persists. You must only install Magisk Manager again, because it is user apo, installed to Data partition that was wiped
You must check on the OK side how they advice installing the updates of OK ROMs
(It is questionable if they will get updates any more, since OK team switched to development of ROMs which install over the stock Pie, whereas on P9 you have no stock Pie - only Oreo, and most likely, we will never see stock Pie for P9.
Just check when OK team released last ROM for stock Oreo, and compare with their releases of OK ROMs for stock Pie:
https://openkirin.net/download/
Hence IMO, for updating the OK ROM (if/when it comes), you will again just need to flash its System and to wipe Data (and then to reinstall user apps like Magisk Manager).
Hopefully, you can backup and restore some apps and settings by Titanium.
Whether you don't need to wipe Data for such update - check from the OK support.
On the Open Kirin site you will find Support pages (Faq, HowTo) and also a link to the live Telegram channel
Hello. I have a (locked) P Smart (FIG-LX1) that came with Android Oreo. It was a good device until it was updated to Pie. Even after the latest security update the phone is still a lot slower than when it was running Oreo, althout a bit better that the fist release (it looked more like a beta than a final release).
The point is that Huawei doesn't provide unlocking codes anymore, what is ridiculous, but being a Chinese company probably there isn't much we can do about it.
I know it is possible to unlock if the phone is downgraded and then using a paid solution, but it's it not an easy solution and not many people is willing to pay or can do it for many reasons...
I don't have any experience with Huawei/Kirin devices but other platforms like Samsung or Qualcomm have softwares that allow flashing while device is in download/EDL mode. This would make possible to flash stock firmware when the device is bricked. Using these tools it is possible to root and/or install a signed TWRP even if the bootloader isn't unlocked, so maybe there is a similar solution for P Smart.
Maybe it's possible using eRecovery? Is it possible to use it to flash unsigned data to the phone?
Any thoughts or info will be appreciated. Thanks.
Update: so far, I have found only two options that seem to work with Huawei phones that use HiSilicon/Kirin processors:
1. Some obscure IDT/Firmware writer that require enter "test mode" (it is normally done by shorting some test pads in the phone's main board), and they may not work with P Smart;
2. DC Phoenix claims to flash files while phone is in fastboot mode even with a locked bootloader, so this could be used to flash a signed TWRP to the phone and then proceed with rooting, etc, but it is also requires a payment for working.
All phones have some "unbrick" tools that work like DC Phoenix and allows flashing firmware in an emergency, and if DC Phoenix works with a simple USB cable and fastboot then there must be a way to flash a signed recovery to P Smart without needing to unlock the bootloader...
I reckon that the easiest solution is using HiSuite to rollback it to EMUI 8.0 (it gives version 8.0.0.176 for my FIG-LX1) and then using DC unlocker. However; it needs to be Windows app since macOS version does not have this feature.
It would be nice to have alternative, though. Did you manage to find any working examples of option 1 and 2?
Yes, the simplest solution so far to unlock is downgrade + DC Unlocker, but it is paid, and unlocking ins't actually needed for TWRP (and therefore rooting).
My phone is still locked and running latest firmware, but for my surprise it got a lot snappier after I did a full backup using HiSuite (I think it reset some settings and app permissions in the proccess). <<< GOOD TIP
Anyway, these are the sites with info about the procedures in my previous post:
1. Huawei IDT flash software - https://co.easy-firmware.com/how-to-flashing-huawei-board-software/
2. DC Phoenix related

DC Phoneix Huawei flash tutotial - https://www.dc-unlocker.com/huawei-phone-flashing-in-fastboot
Again, if it possible to flash "unverified" (i.e. non Huawei signed) images then it is possible to flahs a signed TWRP to recovery or eRecovery ramdisk partition.

Wow ... before backup free RAM was ~1 GB, now it says 1.5-1.8 GB (like Oreo did?).
