Since this Huawei P10 never received a single OTA update (from Carphone Warehouse, SIM free) and was stuck on Nougat I decided to go custom ROM route. This was a HUGE mistake but I did learn a lot which may be helpful to others.
The situation goes like this:
Tried to flash TWRP, failed, tried to flash system (openkirin pie) also failed. Nothing would work at all.
Tried to re-lock bootloader thinking it would make everything stock again automagically (not sure why I thought it does on some devices).
Then got into bootloop with no access to fastboot as bootloader HAD to force factory reset but couldn't (broken recovery). After some time you'd get some white EMUI screen in Chinese where all the options are broken.
Flashed the latest version I could find using DC-Phoenix with flashpoint, this is where I really ****ed up as this firmware had XLOADER2.
Phone is alive!!!! but no IMEI and NCK lock. HCU tool, DC unlocker, etc, nothing works with XLOADER2 for fixing the IMEI or NCK lock.
Tried to downgrade to Nougat. Complete brick, back into testpoint mode.....
Testpoint mode cannot even flash XLOADER1 anymore!! I did still manage to get the phone working again, but now it is a tablet .
So in short:
YOU STILL CANNOT GO BACK TO XLOADER1 FROM XLOADER2 - EVEN if you disassemble and use testpoint mode! I have NO idea what Huawei have done to prevent this but its something evil. So if you are at this point with no IMEI then you will never have a working phone ever again. Tablet yes if you are lucky but NOT phone.
So the process (not detailed, requires Google) to make your bricked XLOADER2 Huawei P10 a tablet rather than a brick:
You'll need DC-phoenix and maybe a 3-day 15 credit license but don't by the license until it tells you to otherwise it might be a waste of money if you have problems with disassembly for example
Download HiSuite to make sure you have all the required drivers
Disassemble your phone, plug USB into the computer, ground the testpoint pin and hold the power button
You should see a HUAWEI USB COM device in device manager
Using DC phoenix you need to select a booloader mode, try all Kirin 960 bootloaders until one works. You can also select an OEMINFO update at this point too if you want
Your phone is now in some half working fastboot mode. Leave it plugged in!
Using firmware finder, find the "379" firmware (the latest one they have for VTR-Lx9) where x is 0 or 2.
Using firmware extrator, extract: xloader, fastboot, teeos, ptable (hisi_gpt or something like that), vbmeta, kernel (ramdisk)
Using fastboot manually flash all of these images, kernel may fail but its OK if it does
Now fastboot reboot, your phone will brick again. Put it back into testpoint mode
Using DC-phoenix to select a bootloader (again) use the same Kirin 960 one as what worked for you before
Use DC phoenix to flash the "379" firmware and customisation and run the update.
If ANY steps fail, repeat again to fastboot reboot, testpoint mode, bootloader from DC phoenix, then run the update.
If all partitions flash OK and it asks you to go into update mode, with the USB connected, hold vol-, vol+ and power until 3 seconds AFTER you feel the phone vibrate
Eventually you should see some more COM ports appear in device manager (PCUI and some other random one). If you can see your screen (doubtful as it will be face down) you will see update mode 5%
Again, update with DC-phoenix (same 379 firmware and customisation you did before)
Your brick should now be a tablet. Bootloader should be unlocked if it was unlocked at the start of the process.
So typing that out and given I don't have time or the load of files I had downloaded to do this there is not much detail so if you do this you need to be someone who knows what they are doing really. I don't expect anyone to actually be stupid enough to follow this.
I just don't understand what XLOADER2 did (must be at a very low hardware/bios level) so completely lock the device down even in testpoint mode. I'd imagine even their repair centres would not be possible to repair IMEI now and just throw motherboard into the bin.

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

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
http://www.android-hilfe.de/thema/downgrade-von-b360-zurueck-auf-b182.813366/
You must first make a step.

I did the same thing is what you doing today I've tried this and it fixed my phone

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
Hello,
I unlocked my bootloader,
installed twrp (this version ->),
tried to install CM13, but failed because of failed to mount /data
fixed that by formatting data
tried again to install CM13 but it still didn't work, because failed to mount /system
i gave up and did a restart just to realise that there is no system anymore i was stuck in a bootloop,
i decided to go back to Stock and used fastboot to install stock recovery for MM using SRK Tool,
choose to relock my bootloader and after the process it said "the device will now restart to perform a factory reset"
since then i'm stuck at the Huawei Logo (i think my device is stuck because it tries to enter the rom to perform the factory reset but there is nothing it can enter so it's stuck),
i tried to enter fastboot mode but it didn't work,
i can't even turn off my phone because every time i hold the Powerkey the phone just restarts
right now i'm downloading the ROM dload file and hope this will help me.
do you have any ideas/thoughts about this, do i have any chance to save my device ?
EVA-L09
was running emui 5 (B361 i think?)
Dload didn't work nothing happend.... is there anyway huawei will repair this ? if yes how much will it cost ? is there a chance they will repair it (warranty) even tho it was my fault, if i don't tell them what i did and play dumb?
If you power off the phone, and then press and hold the Volume Down key, THEN plug in the USB cable (attached to a PC), does this enter Fastboot mode? (white screen with Android logo)

No that doesn't work,
i now leave it on to run out of battery and then i try it again.
Yes - let it go completely flat.
Then, press and hold the Volume Down key, and plug the USB cable in. Once you're at this stage, you can use DC-Phoenix to update the firmware. Once this is successfully done, you then power the phone off, press and hold both volume buttons, and re-connect the USB. This puts it into Upgrade mode, and you can use DC-Phoenix again in Upgrade Mode to write the same firmware to it. Once you have done this, you should hopefully have restored your phone.
You may need to go back to an earlier firmware, such as B136, then go through the upgrade path again, if it does not work with B361.
thanks i will try this
it worked ! i unlocked the bootloader again and i tried to install different version of the Stock ROM (b182,b300,b361) i was able to flash b182 and B361 without errors by flashing system,recovery and boot.img but my phone always boots into erecovery and i have no clue why ?
I was in a similar position - until I did the steps I noted with DC-Phoenix.
You don't need to mess around with unlocking the bootloader by using DC-Phoenix.
what is so special about DC-Phoenix and why does this cost 15 Euros for 72 Hours ???
i had the same situation sir
i don't know what to do now
there is no huawei service center in our country
i cant use dc phoenix because i cant pay the 15 euros via paypal

hello guys
i have a serious problem here
this is what happen to my P9 when i try to unlock/root/install twrp
first i used SRK long chod v2.0 tool
the first step i do is unlock the bootloader and yes i can say it works
i unlock the FRP and Bootloader
then i proceed to the next target. installing the twrp recovery
i try so the twrp version inside the SRK tool
but doesnt work then i look some version from
official twrp website , same again does not work either
so i skip that part , and stop going further in order to
back my phone to unvoid the warranty
there is an option in SRK tool which you can relock your bootloader again
so i did relock my bootloader and after rebooting the system
boot stuck appears
no fastboot/no recovery/no system
even the key combination does not
work like forced update via sdcard/dload/update.app
i have no idea what to do now
but i read the thread from SCRAFI
that he used the DC Phoenix and
resurrect his bricked P9
i want to try that solution but i have a problem on that
i cant buy credits for 15 euros i dont have
any e-payment online like paypal bankcards/debit
because before you can use the dc phoenix tool
you are required to login your reserve account
for able to use it. and that is why im so hopeless that
i can ressurect my phone again
please help
please give me some account login for dc phoenix
and promise to bring back the 15 euros via
remittance or any available bank payments..
please. any one who has a big hand
please help me

I know this is very necro, but I've come to encounter the same problem. However my situation is weirder. I did very similar steps: wanted to go to stock and used SRK Toolkit to flash the recovery and relock the bootloader, I'm guessing it was not the correct twrp version for my current os. I should state that I don't understand anything about how huawei works... by now I just want the damn thing to boot . My situation is that the phone vibrates and displays the huawei bootlogo and then hangs. I've let the battery die and then do the Vol- + Usb thing but it doesn't give a f***. It just keeps going to the huawei logo. I've already ordered a pentalobe screwdriver on amazon to try and disconnect the battery cable...maybe it'll make a difference, since its kinda sketchy to try to let it die but no so much that it won't even boot and just shows the charging icon...:angel: ***fingers crossed*** anyways if someone has any hints I'd aprecciate it. Wish me luck, cheers
Edit: today, 3 days later, I re-tried to enter fastboot with vol - and usb in pc and IT WORKED!! unlocked the bootloader and now everything is fine.
I've been trying to contact huawei for a couple of days, trying to get my p9 back to alive.
well let me explain how this is happened :
couple of days ago, I was on nougat firmware and few games that I play isn't optimized for nougat yet so I planned to downgrade to marshmallow via rollback and update.app package. First I install the rollback package via internal storage and its success, second, I rebooted phone and insert my sdcard to install update.app from official huawei and its say success then it rebooted itself after 100% flash. Then I realized that my phone isn't came to boot, I try to reboot again but no success getting to boot screen. I try to reflash the update.app thru dload mode but dload mode isn't boot anymore. trying to boot into erecovery but it never show up. Think I'm broke my recovery at this state. Then I try to boot into fastboot mode and its success. Unfortunately, It says frp locked and phone locked ( yes I formatted my phone on nougat earlier thinking that the cause of lag is maybe I dirty update it without clearing data etc like flashing firmware and I forgot to turn frp off )
This phone is mine and not stolen. I can provide you my google data and prove it with ss on my google account manager that this phone is already been bind to that account.
I wanna know how to turn frp lock off?
Trying to fastboot frp-erase but didn't solve my problem
Trying to fastboot frp-unlock but it ask me for a password (trying to insert bootloader unlock code but it says password matching failed)
Trying to flash anything but it says remote: command not allowed since my bootloader locked again due upgrading to nougat.
And, I dont want to pay for dc-phoenix since I want to learn myself how to do it from you guys
Thank you!
You won't learn anything, because your phone is ****ed up In real mess and you must pray even to recover it with DC phoenix ... and yes, you must pay them

Hello folks,
so a friend of mine is a complete noob and have this problem with his p9 plus.
The phone keeps rebooting itself in an endless loop, i can't access recovery and only when plugged in to the PC i can access fast-boot.
Phone is locked, FRP Lock.
With getvar command i managed to get this info:
rescue_phoneinfo: VIE-L09C113B170
seems that there is no full zip of this rom anywhere just partial ota (found those with firmware finder) but even with that when i try to flash recovery i get command not allowed.
On the fastboot screen of the phone i have this reboot reason AP_S_PANIC
anyone knows a how to get the phone out of this? (i was thinking that maybe unlocking the bootloader could be of any use, but in the request page it's needed the Product_ID and i don't have it. (can't *#*#1357946#*#*)
I don't know if it does work in a locked bootloader.
I have my P9+ for a week and maybe if you download a firmware compatible with your version and try to 'hard' update the phone, using a SD card with a update file on a dload folder and restarting the phone pressing VolUp + VolDown +Pwr, you can restore your friend's phone.
I'm sorry if I didn't help, I am myself stucked trying to rollback my version to MM and have the NFC and the Bluetooth working again...
myself also got this problem..please anyone..
Hi there,
This is for EVA-L09.
How this came about:
I was relocking my bootloader when it failed(fastboot changed to locked though) however, continued onto reboot anyway. It didnt reach the EMUI lowlevel wipe stage
Device info:
EVA-L09
Nougat
C432 B391 (If I remember correctly)
FRP unlocked
bootloader ???
phone functionality:
whenever it turns on I just get huawei logo regardless of key combos
seemingly unable to fastboot
Unable to force update (Vol +&- & Power)
Unable to recovery mode
I was wondering if anyone has had a similar situation or any insight how to fix this.
Most solutions I've found require fastboot but once my device starts charging the logo appears then only restarting by holding power is available.
I expect the cause to be the issue relocking the bootloader.
thanks for any insight.
Edit/Notes: I have sucessfully unbricked this device before via the dload method however unable to. (rollback to 4.1EMUI and 6.0 then changed to C432 B168 and upgraded from there)
I do have a DC Pheonix account on standby if I ever can fastboot

As you say, you cannot go to Fastboot even by power off, Vol- and connecting USB?
It doesn't help now but when you were relocking (btw why, but you may had your reasons for), did you have clean stock without root and TWRP (since relocking ininitates full reset)?
TG, I never used DC Phoenix but maybe you can unbrick by Method 3 (seems, it does not rely on Fastboot?):

sometimes people do mistake trying to boot in fastboot while are not conected to pc, connect phone and pc with usb, then try to force restart holding power more than 30 sec together with vol -. If cable are not connected, you never will boot in fastboot and find a way to test if your usb cable working properly!! i bought one non-huawei cable, it was new, but with that cable i wasnt able to boot in fastboot, duno why, so there need to be original cable for this! (maybe i bought foulty cable, duno , with non-huawi cable i can easy charge, transfer data to pc, but when tried to use adb comands, sometime it worked, sometime not, but with original cable got no problems at all)
Thank you for both of your comments. I have now successfully recovered via DC-Phoenix.
I was just getting unlucky with holding down the Vol - key it seems as I eventually got into fastboot which then allowed DC-PHOENIX to solve the problem.
The Huawei wire which I bought is third party and I have noticed connection dropping which may have caused me to not enter fastboot as it had unconnected(but not visibly). This happens during normal system boot as well when I'm trying to use MTP.
