Hello guys!
I have bricked my P9 EVA-L09 today. i want to update it to android 7 with update from erecovery. i put files from update_data_full_hw_eu.zip and it went good but phone wont boot up and the second file "update.zip" ive extracted to dload but phone cant install it. I've tried many things to unbrick my phone but i cant do it. flashing system via fastboot is impossible cause it says that it cant be written. i have no root ant no bootloader unlocked. Please help me guys QQ
If you have C432, try this:
1. install via sdcard + 3buttons UPDATE.app from HUAWEI_P9_Rollback Package_EVA-L19_from Android 7.0_EMUI 5.0_to Android 6.0_EMUI 4.1_C900B300
2. install via sdcard + 3 buttons HUAWEI_P9_Firmware_EVA-L09_Android 6.0_EMUI 4.1.1_C432B182_Western Europe

try installing 6.0 firmware for you model.
i cant go to eRecovery, i cant even shut down device - only full discharge can make it.But i can go to fastboot. Ive tried with fastboot commands but i have locked bootloader and every time my flashes are rejected by phone. The simpliest metod - HiSuite send me message: "no recovery packages are found for your phone model". It should be a way to unbrick it with fastboot but i dont know how.
Hi I was in your shoes yesterday I had to pay for the dn Phoenix to fix my phone it uses a backdoor to install firmware from fastboot
You could try and look for the backdoor commands I found this , I would post a link but can't yet

I will try to send my Huawei to warranty service and if they wont repair my phone ill pay for DC Phoenix too
I had the same problem!
Hi there.
Was in the same situation as you not so long ago.
Get a micro SD card, plug into PC, create a dload folder then download the rollback file from the Huawei website.
I'm a new user so can't post URL. Just Google "Huawei P9 rollback" should be the 2nd option (consumer.huawei link)
Put in the dload folder and put into your P9.
Press and hold power, vol up and down together till the Huawei logo appears and let go when you feel the vibrate.
This should force update and restart. (does not rollback to email 4.1, only unlocks the rollback from emui 5)
Next you need to download your previous firmware, in my case I'm in the UK with unlocked P9, so I downloaded EVA-L09C432B166.
Same again, put micro SD into PC, delete the rollback file and put your firmware in its place.
Put back in the P9 and repeat the above force update.
This will put you back to working stable stock.
For further reassurance, download a build previous to B166 so when it's up and running you can search for an OTA update to make sure all is in order.
Hope this helps.
Did you meant that the rollback flashes without going to eRecovery? I said some posts earlier that i cannot enter eRecovery so i cant dload anything. Im stuck on Huawei logo all the time do you think than i can flash something via dload without going to eRecovery?
erecovery is different.
I'm saying to do a force update, but in order to do so you need a microSD card.
Erecovery involves holding power up while connecting to PC in order to use HiSuite etc to recover.
Force updater tells the phone to search for dload folder on SD card or phone and install the update before trying to boot up OS.
So, if you connect microSD to your PC via a card reader etc and not via your phone, you can create a dload folder, download the rollback file from Huawei (above) the file is only around 80mb or so, plug the SD card back into your phone while powered off, hold down Power + vol up + vol down. The Huawei logo will appear, when it disappears let go of all the buttons. This should bring up the Update screen.
At this point the phone will install the rollback file. and this will bypass the rollback prevention in emui 5 and therefore allow you to install a previous emui build (4.1)
Again though your phone will still not boot at this point as there is no OS working or installed.
So you need to download the corresponding firmware for your phone/country/operator. Once downloaded, remove the memory card from the phone, connect to PC via card reader, delete the rollback file you placed in the dload folder and replace it with the downloaded OS and repeat the process used to install the rollback.
From there you should be back to stock marshmallow.
I should point out the files you download may be in zip folders. You need to extract the "update" file and that's what you place in the dload folder.
Hope this all makes sense, if not I can make a YouTube video and post it.
Good luck.
Now i know what did you mean, but sadly i cant update it too. I tried with my friend's P9 and when i hold these 3 buttons then shows special update screen and in my P9 it doesnt probably because of my bad flash rollback for P9 EVA-L19 and i have EVA-L09 model

The rollback package for L09 model is here: http://download-c.huawei.com/download/downloadCenter?downloadId=91892&version=363759&siteCode=es
Inform the results please.
I made a video to better understand. This wideo is showing that phone isn't searching any dload folder. https://youtu.be/oD9AI_6SqLs
edit: i have tried your advices to put rollback and try to dload it and then same with firmware but there is no reaction i didnt see there any circle with progress of flashing (like it was before i flashed rollback for L19)
Mine is now doing the exact same thing - I too tried the dload method to update from C432B182 to C432B361 and it's screwed my device up too.
Until I tried to use the 'rollback' package, it would at least allow me to power off, so I could get back into the Update screen - after doing that, and trying the B182 again, it's got into this position where I can do literally nothing with it. No combination of buttons, no matter how long I try to hold them, seems to do anything.
An update...
After letting my battery drain completely, I have been able to get into Fastboot mode, by pressing and holding the Volume Down button whilst connecting a USB cable to my PC.
From here, I have been able to run DC-Phoenix, and have been able to write some .APP files to it - which has at the very least got it booting into eRecovery, rather than the boot loop it had before, but is still not fully booting.
It looks like I might need the full, original firmware, in order to proceed?
And I've got about 68 hours left to flash using DC-Phoenix, or I'll have to spend another €15!
Yes you download the original firmware unzip it and put it in the "dload" folder of SD card then do a force update. Hold all the buttons vol + vol - and power
Help Please.......
So I've owned sammy devices before in the past and never been afraid to flash custom kernels/roms etc on them. Since the p9 was the first Huawei device I've owned i was a little scared to flash it. But it got too much for me and i tried, and fail Now i have a P9 that doesn't work and a very upset wife because I've killed my phone.
So what i did was tried to flash via dload 3 button method a nougat fw (official)but had no camera/file manager/calendar etc. Found it was possible to downgrade via flashing a downgrade fw. I cant remember what nougat fw i tried to flash but in the about device the build number was nrd10testkeys or something like that. My official fw before was EVA-L09C706B145. After flashing the downgrade fw my phone rebooted and just hung at the Huawei boot splash screen. All i can do now is access fastboot by holding vol - while plugging in usb. I cant access recovery/cant boot past Huawei splash screen. I have tried fastboot flashing via adb but it fails due to permission error (thinking because of locked bootloader?) Have tried using Huawei updater with hisuite to recover device, download, unpacks and installs recovery to 99%then fails. Pleaee help me fix my phone so i can get back into the goodbooks with the wife.......

Try following post #4 instructions from here: https://forum.xda-developers.com/p9/help/failed-downgrade-nougat-to-mm-bricked-t3464156
I have successfully unlocked the bootloader and managed to install TWRP 3.1.0-3 but that's about it. I cannot install any other TWRP version but the one I mentioned. I tried installing Magic Rainbow custom ROM but it doesn't work properly (apps are super slow, entering developer settings makes the settings app crash, can't set a password etc.). So with that I can at least access the phone interface with limited options. Developer settings crashes when I choose it; if I can get through then I can't enable USB debugging, it keeps turning itself off right as I enable it. I can't use update function so I have to use 3 button installation, which randomly fails to work very often. Due to this I haven't been able to install any updates.
I kinda gave up on rooting already, I just want to get my old firmware back at this point but I can't even do that. SRKTools stock marshmallow recovery doesn't work either. It's as if TWRP 3.1.0 has taken over everything. On the rare occasions that I managed to get EMUI update via 3 button installation it would say that the update doesn't match the current version (or something like that). I tried using recover for b378 and managed to run the 3 button update but it always gets stuck at 5%. It gives up after a while, tries booting twice and then goes into eRecovery screen. My bootloader PHONE unlocked text is in red if it matters.
I've been actively trying to fix this for the last 11 hours (yes I'm not exaggerating at all). Please, PLEASE someone help me out with this!
I've also tried using the unbrick tool of the latest SRK Tool 2.0 for b378. It goes flawless, phone restarts and does a factory wipe but then doesn't boot after the Huawei screen. It tries booting twice and then it goes into eRecovery screen. Have I ruined some hardware here?
It seems like 3 button upgrade is my salvation and it doesn't work. Many times I hold it down, I get a slightly different screen but it again hangs at booting text. I managed to flash all recovery, boot and system image files and got the installing update screen in my b378 update, but it hangs at 5%. I couldn't even manage to get the installing update screen for common b136. Also when I try to flash system.img I get an error with flashing system which is FAILED (remote:sparse flash write failure).
First at all: The Magic Rainbow custom ROM is based on B383 so it wont work on B378 firmware thats your fault here.
Just flash the rollback package (find it in my signature) and after this flash B383 or if it not work start with B136. U have to do all with the dload method.
Fast solution?
https://forum.xda-developers.com/p9/development/p9-moonlight-rom-v1-0-b378-stock-t3567223
flash the B378 version. probably your problem is solved by this.
I'm very well aware that Magic Rainbow doesn't work with b378. That's probably the reason I have those issues with it. But it's the only way I can access the phone's interface in case I need to use it for a fix.
I tried flashing b378 already multiple times, without rollback and it did not work. Is it safe to use the rollback though? My oem is c432, would it create any issues to use that? Should I flash c900 oem first or can I go with the rollback right away? I literally cannot install any stock rom without having frozen/looping bootscreen atm so I can't complete any step that requires me to do that.
I've also tried flashing b136 plenty of times already. I can't even flash the system.img. I can't flash the system of any of the b100 series.

u tried the rom i mentioned?
it is safe to use the rollback package. any firmware after will retrive your oem to c432. so you dont need to flash the oem info package.
1. flash rollback package via dload (watch out to have only the UPDATE.APP file in dload folder)
2. flash B383 via dload (2 files need to be flashed!)
3. flash special SuperSU_for_EMUI5.zip
4. have fun
again if u can boot magic rom then you can flash and use Moonlight rom v1.0

I cannot flash rollback using 3 buttons method. I see the "your device is booting now" text and then it goes to TWRP menu. Nothing happens. This is what I mean with 3 button method not working. Every single update fails probably because of this. Is there anything else I can do to flash it?
I've also tried flashing b378 and then doing the rollback. Still doesn't work: It hangs at 5% as it did with the b378 update.
Also, is there a special way of flashing those 2 files of b383? Is it just one after another? I doubt I can flash them at the same time since they have the same name.
YES IT WORKED! Thank you the rollback actually made the difference. I had to go for b136 and then upgrade manually through there with the stock OS though. And I believe rollback changed the status to LOCKED instead of RELOCKED. And I was a complete moron for I couldn't do 3 button update because my cable was still plugged in. I had a moment of epiphany when I noticed what the symbol actually represents. It was like discovering who Keyser Soze was lol. Let this idiocy stay here for there might be others like me; this way they might fix it without embarrassing themselves like I did.
Glad it worked for you.
Next time just read the threads in this forum.
There are several toturials how to flash the p9 the right way.

Every time I try to flash, with 3 buttons method, it puts me "software install failed"
I tried to flash official rom with twrp but he can't finish the process.
I tried to flash custom rom. When I want to boot, he bootloop.
Hi,
I am at a complete loss and going round in circles. My phone has bootlocker unlocked message at moment. In adb fastboot devices finds the phone, but the SRK tool fails to find it sticking on 'waiting for phone'. I tried to flasg the Huawei rollback but that fails (presumably due to being unlocked). I cannot relock via fastboot as that gives 'remote: command not allowed' error.
Update
- I have just checked fastboot - it says Phone Unlocked & FRP Unlock.
- Next I used Huawei Update Extractor to get boot, recovery, cust & system img from the "HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0_EMUI 4.1_C432B166_United Kingdom_Channel-Others" Package.
It seems I still cannot boot and device still says unlocked etc..
Update 2 :-
Copied the dload/update.app file from the HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0 zip. Managed to get it to start installing, only to get Software Install Failed msg. However reboot let me start the phone. So currently have Build No: EVA-L09C432B166 on.
At this point I just want my phone either back to initial factory state or able to flash roms, whichever is easier to get to. Any help greatly appreciated. I've been getting nowhere following guides I have found, so would really appreciate some help here.
Thank You

Ok first of all, using TWRP back up everything you have there (backing up SD card isn't really needed unless you plan to wipe it too). Then, using TWRP again just wipe everything but OEM and SD card (external storage). Then, create a folder called "dload" in the main SD card directory and put ONLY the update.app in it (use the stock b136 as suggested). Now you need to flash a stock recovery using bootloader again. Just use the Huawei Update Extractor and get both recovery.img and boot.img from the rom that you're using to flash (in this case b136). Put them in the same folder as adb. Run adb cmd, write commands "fastboot flash recovery recovery.img" and then "fastboot flash boot boot.img" and finally "fastboot reboot". Quickly unplug your usb cable and use the 3 button force update (Vol Up+Vol Down+Power button all held together and don't let go until you see the update start). It should work without a problem if you had managed to wipe everything using TWRP. If it still doesn't work you could try deleting OEM info as well and flashing a new one (c432) which you can find on the forums. Back up is important in case it still doesn't work, you might need them to undo things.
If it boots, it means you've learned how to do it and you can probably unbrick it as much as you want haha. You can update to Nougat (7.0) and EMUI 5 using Huawei Updater 2.0 along with HiSuite, there is a guide here on the forums to do so by updating to b182 then to b360/b361>b378>b383 which I was unable to find for now. After that you can install a custom rom without an issue. I figured I wouldn't mess with it anymore but frankly it's likely that you are just soft bricking by skipping something very simple and failing because of that unless you went ahead and did things that you are explicitly told not to do so. If you end up having it unlocked/relocked might as well try and get a custom rom really.
If the update gets stuck at 5% or you have the icon of a usb cable end with a lightning on it your mistake is that you didn't unplug it. If the update keeps failing without these it's likely that you're using the wrong firmware and you could try using another one (FULL+PV+MV ones if you're going for a higher one). Or you could try to follow the rollback and then the update as I did. if you do the rollback then the update, your phone might get a LOCKED status again (yes not relocked).
If you are missing something or you think you have a stupid question and too shy to ask it here just PM me.

So you're saying that you're able to boot your phone on stock b166? Then update it to b182 first. I had to keep pressing the check update for a while before it popped up. I was busy at the time so I didn't mind the wait time but I bet you can do it faster forcefully, got to be a guide around here somewhere. Here is the guide to update it all the way to b383 from b182.

I'm on B166 currently. Phone tells me it has update for B182, on reboot I get the device unlocked message and it sticks on 'Your device is booting now'.
Also tried Huawei updater....that sticks at 'Listened on Port 41279'

Getting the device unlocked message shouldn't indicate anything, only that you didn't lock it again. It might be that you didn't install your current rom correctly. You could try flashing TWRP, backing up everything and then wiping all of it f. It means you'll be romless for a while but worst case you can recover what you backed up with TWRP and then flash it with a stock rom again. There are guides to flashing everywhere and I've made my own guide here. I can't really give you advice on your situation since I haven't ever been there. I just dabble with these things, so I can't really find a solution for everything.
You are connected to HiSuite while running Huawei Updater right? It needs to be able to see your phone (usb debugging on or HDB mode) and set to usage via proxy.

Run HiSuite. Make sure your phone is connected to it. Top right you'll see 4 buttons: 3 horizontal stripes, minimise, full screen and X. Press 3 stripes one and choose settings. In the first tab called General under the 4th section you'll see Proxy. Enable it and enter 127.0.0.1 for address and the given listening port as the port. Leave the username and password blank. Press apply. Then you probably have to choose the system upgrade from the main screen of HiSuite. I don't recall exactly but this is about how it goes.

i have hard bricked my phone i have installed Elite rom for my nem-l21 and it was going perfectly, and i have made backup of my stock system but after booting it up it goes into bootloop and Huwawei eRecovery comes in, i cant access fastboot or twrp by button press only Huwawei eRecowery. I tried install stock rom by update.app but it is not compatible. My PC sees my phone when is off as NEM-21 in device manager but it isnt showing up on adb devices neither on fastboot devices. Please help because i have no idea how i can fix it. :crying:

Try to use the Multi-Tool for team MT,maybe it will help you to unbrick your phone,i`ve used yesterday to unbrick a Honor 5C NEM-L21.You will need the update.zip for you phone and Huawei Update Extractor.
Or try DC Phoenix
I was using Android 9 and did an unsuccessful downgrade to Android 8 via HiSuite. Now my phone is completely "dead", the screen and the LEDs give no sign of life. All I can do is get into fastboot mode. No matter what I do, the phone is always in fastboot mode.
(1) I already tried to flash lld-board.zip with this, but to no avail;
(2) I tried to flash an Android Pie firmware, but to no avail;
(3) I also tried to flash an Androd Oreo firmware, but without success.
Does anyone have any advice? DC-Unlocker + HCU can revive my cell phone?
