[GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop

Hi
I see someone here have problems with bricked phone. It just keeps restarting and you cant even turn it off.
The problem is here that UPDATE never ended to 100% and software successfully changed boot.img to the new one
but with old system on the phone.
Its even worse if you have TWRP recovery installed before update then it will brick the phone too.
Allways install stock recovery on current rom before update firmware.
Ok i will start now with this guide because i had same problem and fixed it by myself.
I will not put any links to downloads find them self GOOGLE is your friend
First of all if you were on B200 5.0.1 version of android then you need B170 firmware to extract boot.img and recovery.img from
the UPDATE.APP file
For that you need a software called Huawei Firmware Extractor
Download it and install
Now you need even ADB/FASTBOOT on the computer. If you dont have download and install. Install even drivers for the phone
Now Open the Huawei Extractor and add the UPDATE.APP file.
Now you will see alot of files below
Now mark the boot.img system.img and recovery.img and extract them to the desktop of your PC
Now copy those files to the ADB/FASTBOOT folder.
You phone i still under the bootloop and you need to get it into FASTBOOT mode. Only way to do it is to plug in USB cable to the phone.
Now as soon the phone reboots by itself hold Power and Vol down button until you see white screen and fastboot mode
Now go to the ADB/FASTBOOT folder where you copyed files and hold shift and press right mouse button to get "Open command window here"
So you will be in fastboot and you will see C:/ADB that is right directory
Now start with fastboot erase cache
Then write fastboot flash boot boot.img and hit enter
When done do following fastboot flash recovery recovery.img and hit enter
You can if you want even try to flash system.img by writing fastboot flash system system.img or fastboot flash system.img dont remember that combination
but try and see wich works.
Now write fastboot rebootand phone will reboot . If you still have bootloop then as soon phone goes black then Hold Vol+up and Power until you see recovery.
Over there make factory reset and cache and then reboot.
If you still cant boot into recovery then you need to get Firmware B170 and put it on you SD card in DLOAD folder
to flash it from scratch. Same here is that you need to have USB plugged in in order to get to EMUI flash mode or it will wont work.
Remember that you only need UPDATE.APP in the DLOAD folder from B170 firmware.
I know my English sucks but im trying to help...

Yes, this is the your mistake
Never update firmware with instaled TWRP. First you need to flash to factory recovery then install the original firmware like B170(B200), then update to Marshmallow

Nevermind, fixed it.

You don't flash img files through the recovery. Flash recovery.img, boot.img, system.img and cust.img manually through the fastboot screen (vol down + power) using either the windows command or mac terminal.

Thank you, at the moment I'm trying the same.

Which firmware, I've tried with full B200 and extracted images, but no success. B170 ?

Don't have success, please give advices ?

1. I Download the B313 update and extract the boot.img and recovery.img from update.app using Huawei Firmware Extractor.
2. Connect your P8 to your PC/Mac. Hold down volume down + power just before you feel the vibration and the Huawei logo shows up. This will boot you to the Fastboot/Rescue screen.
3. Using the windows command prompt or mac terminal, flash the B313 recovery and boot images using Fastboot:
Code:
fastboot flash boot boot.img
Code:
fastboot flash recovery recovery.img
After flashing these, if you reboot normally, the bootloop should be gone but you will get stuck at the Huawei logo. However, you'll now be able to access recovery (volume up + power) and the 3 button update (vol up + vol down + power) modes.
You can now reboot either holding the power down or issue a fastboot command:
Code:
fastboot reboot
4. This may be optional and may not have any bearing but at this point I was ok with losing data just to get the phone booting again. Boot to the recovery (volume up + power) Yes, it's not that easy using the buttons. Just try it until you get the recovery to boot.
In recovery select Wipe data/factory reset and Wipe cache partition.
5. Download the B170 Full ROM and extract the dload and custom folder to your microSD. Use a card adapter/card reader.
6. IMPORTANT: Disconnect your P8 from your computer if it is still connected. Doing the next step while you're connected through USB will cause the update to get stuck at 90% and if you force a reboot, your device will bootloop again.
7. Reboot from the recovery and boot into the EMUI Updater using the 3-button method (volume up + volume down + power). Let the phone update and voila! You're back in business!

Confirm, it works!

so it works , i have to gflash boot,cache and recovery img from b313?

I've interrupted update (B313), write to SD /dload full B200 and started Recovery. Update gone just fine and phone started with brand new B200. Even don't reset or wipe !

Hey TopperBG,
i'm in the same Bootloop as you described.
I tried every ROM I found on the internet but the combo with Vol Up + Vol Down + Power won't work. There ist always a fail after 1 % loading.
The second I tried was on fast boot. Problem im my boot loader is locked. So there is no chance for me to get something flashed.
Last option was your comment. I've loaded the B200 Rom on my SD-Card in /dload and tried (the second time) the Vol Up+Vol Down+ Power combo. No success. Then I tried just Vol Up+Power to get the Recovery mode as you described. But I have no chance to boot to recovery mode.
Do I forgot a step ??
Please help
Thanks
Flo

Tell me first what you've done when become to bloop ?
With boot and recovery from that ROM you must flash.
If you can forcibly start update (vol+ vol- power) you have a chance to update properly with update.app in /dload folder

I tried to update through local update on the Phone. But not with .zip. I tried the .app directly. Now i know it was the wrong Choice.
Flash with fastboot is no option for me because of the locked bootloader.
If I do the Force start with the new marshmallow rom (update.app) there is a warning that i'm using the wrong version for my phone.

(Tutorial) Recovering a P10/P10+ Brick

Here’s what you need to fix your P10/P10+ brick.
This method was tested on a bricked P10 (didn’t test on the P10+)
Bootloader already unlocked + Code (no need of twrp)
SD Card
Custom recovery (fix the entire update process)
Stock rom UPDATE.APP from update.zip and update_full_xxx-xxx_hw_xx.zip
for your P10 + P10+ (choose the one you want to install, no need to be the one that come from with your P10, it could be the most recent one but linked to your exact model)
Be patient
Extract the stock rom update.zip and update_full_xxx-xxx_hw_xx.zip, both have an UPDATE.APP,
we are going to flash the one from the update.zip first and repeat the same process for the update_full_xxx-xxx_hw_xx.zip one.
(1)Get ready your SD card
Insert your SD card on the PC, create a folder at the root and name this one dload, move the update.APP from the update.zip
to the dload folder.
(2)Boot your phone in fastboot (Hold Vol- + Power) USB cable need to be plug
Launch terminal on OSX or Windows with adb/fastboot
Write the command fastboot flash recovery customrecovery.img
(3) Before rebooting your phone, insert your sd card that contain dload folder (update.app stock rom from update.zip) inside your P10/P10+
Turn off your P10/P10+
(4) Unplug the USB cable and hold vol+/vol- 5 to 10 sec or (until you see the message this device can not be trusted)
(5)Now the custom recovery updater should trigger and your P10/P10+ is updating, wait until 100% (it restart by itself).
(6)Your P10/P10+ should now boot without problem (bootloader locked)
(7) Is not finish yet, you are going to face NRD90M Test-keys that is normal, you simply need to
flash your cust.
(8) For that, we repeat the same process than before but instead of using the update.app from update.zip, you use the one from update_full_xxx-xxx_hw_xx.zip and replace the one you have on your sd card (dload folder)
(9)reboot your P10/P10+ in fastboot (with of course USB cable plug and hold vol- + power)
There you simply write the command, fastboot oem unlock yourcode. Your phone is going to reset to unlock back your bootloader and you need to go back to fastboot
(10) after that, you reflash again the recovery with customrecovery.img using the command fastboot flash recovery customrecovery.img
and you reboot again in the custom recovery mode (same than before) there the P10/P10+ is updating again, take a few secs
(11) the P10/P10+ will restart and boot in the UI, congrats.:good::good:
P.S : This process was not possible without proper change in recovery and manipulation, hopefully it help you
to recover your brick.

This sound interesting if this method is working both P10 and P10+. It mean that we can rebrand all of L09 models to L29 easily. Am i right? No more FunkyHuawei.

Not sure about the rebranding, for that you need to mod your oem info and product/vendor id.
There is no need of FunkyHuawei, I actually don't support those kind of forcing.

Question about the bootloader relock
the command to relock is fastboot oem relock yourcode.
Now about your issue, did you try a wipe cache/wipe factory/reset, go into the stock recovery and do a wipe cache/wipe factory reset.

Carefully, they use the same name (update.zip) but one is the full ota, the other one the ota mf (cust, etc. the one that you need to flash the second time)

Update cust/hw xxx

Thanks about the relock command. I'll try it when I recover my phone.
I tried that, but it's like I don't have the full system installed, I tried a "full" ROM on the first flash, but I don't think it was actually a full rom, it was too small, I wanted to try another one, but the file being over 4gb I can't even copy it to a fat32 sd card... If I find another version that is a little smaller, maybe I could try, but now I only have erecovery, can't access anything else, hope it's enough.

I'm having a problem at step 4, it says software install failed right after 5%.
Just to confirm what I did. Press all 3 buttons (vol up, vol down, power) on until screen shows message.

Guys check this thread https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108 it will flash the complete FULL Firmware and you also got your bootloader closed again

I'm having the same problem, can someone send me the files to the VTR-L09 C432? Or maybe the VTR-L29 if my phone supports it, I'd like the dual sim feature.
Just to make sure I'm using the right firmware.
If I find a solution I'll share it here as well btw.

Does it work for P10 Plus (VKY) ? I only see VTR oeminfo/recoveries files in the zip.
Edit : I went ahead and renamed everything in the VTR folder to VKY (except for eominfo files, since I just want to update), and it worked ! Updated from VKY-L29C432B123 to B130

Hi all,
I have the same issue software install failed right after 5%. Did anyone get past this?
What other files other than update in dload folder need to be present?
Thanks

Really interested in this one too. Do you have any additional information please? As I just have plan to pull the trigger on funkyhuawei method during the next weekend... But of course I would rather use this manual method if possible.

Guys, did you flash the custom recovery before trying to update.
You really need to flash the stock recovery with the custom recovery, this fix the 5% update fail.
You can also flash recovery2 with.

Write that you need to extract customrecovery.img from customrecovery.zip. That would be understandable.

Hi,
does this work - i bricked my Huawei P10 with VTR-L29C432B113 firmware like this
Installed TWRP and i flashed magisk.zip -> that worked for a while
But on next phone reboot it says there is no space on the storage 0%
Now i cant do anything - phone is not usable..
Exept booting twrp and fastboot&rescue mode wich shows
PHONE unlocked
FRP Lock
When i try to
fastboot flash boot boot.img it says that stupid message command not allowed..
I tried to put in a SD Card with the folder dload and an update.app on it in and tried to flash it via VOL+ and VOL- but that fails
Does the provided method work or what can i do?
Thanks! chrizz

i can't remember the version but im sure it all arounds in 2.1...something

no i wasn't load the Nougat version because i know i am MM the only thing i remember is the TWRP i load is from SRKTool Lod Chong there was an option there to install twrp recovery

can i be able to enter the fastboot ?
if i can go over to fastboot i can repair this
but i can't go fastboot
volume rocker technique doesn't work
even using adb reboot bootloader too
when i am doing volume down ( hold )
the phone only vibrates then stuck at logo
even when its connected to adb command
when the phone reboot it stuck at the logo

Easily Unbrick Your Phone via this method
https://forum.xda-developers.com/p9/help/huawei-p9-brick-easiest-to-unbrick-t3662350

Phone can't boot stuck at "Your device is booting now" Please Help

Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery
Code:
adb reboot recovery
. When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same. Now when I try to reboot the phone it shows ultra low baterry symbol and then boots to "Your device..." screen.

Which twrp you flashed? Check the correct twrp in my signature for honor 5C repository.

Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery . When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same.

Hi hassanjavaid8181
I think I have the same issue here, phone is stuck on "your device..." screen forever and it's impossible to do anything else (reboot ends up on the same screen).
How is it possible to flash twrp or stock recovery if we are stuck on this screen ? Fastboot doesn't see the phone...

Meaning you can boot to fastboot but your pc doesn't recognise it?

Did you try all method to going in fastboot.by adb fastboot command or by pressing vol- and power button?

Hi guys, thanks for your replies.
I somehow managed to boot to fastboot after waiting for the battery to go out completely. From there I used the following commands in ADB from the extract of a stock update.img :
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And it worked ! The first boot was veeery long and now it's normal again.
Now my last concern is that I still have bootloader unlocked. As I wish to come back to factory state and avoid the warning message on boot, do you guys think it's safe to re-lock bootloader ?
I'm kind of scared to try anything else and screw the whole thing now
Thanks again for your support

Can you please explain to me how did you managed to boot into fastboot? I tried waiting for the battery to drain completely. Now I can't fully charge my phone. When i connect it with charger. It starts normally charging like it would with 0% battery then after a few moments the honor logo shows up and then the screen "Your device.." shows. When I try vol- and powerbutton it vibrates and shows the red lightbolt then after few moments it boots the same way into the your device screen. When I connect it to the pc it doesn't react. I don't even hear the classic windows beep sound.

When I remove the usb cable it's still the same. When i try to press the power button it vibrates shows the low battery red lightbolt and dies. If you mean by erecovery emui recovery, then it looks like it's not installed.

You need to press power + volume down key to boot into fastboot. Keep trying 4-5 times sometimes it takes due to wrong press

So I managed to get into the fastboot. Where can I get boot.img, recovery.img and system.img? I have downloaded some update.zip files from this russian site (first 5) http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=NEM-L21&firmware_page=0. But I don't have boot, recovery and system images in these zips.
I also tried reboot in fastboot but its still the same:
fastboot devices
8SC4C16A13006909 fastboot
fastboot reboot
rebooting...
finished. total time: 0.026s[/CODE]

Meaning the fastboot is accessible.
Now you have firmware zip, extract it amd you will get few files. Use dload method as given in my signature and you are good to go.
Else use Huawei extractor and browse to update.app you just got in above downloaded zip. You will get boot, recovery, system img you need.

I downloaded some firmware versions and extracted them. I don't know which is for my device. So I tried one of them. I flashed boot.img and recovery.img but I din't flashed the system.img, becouse it was too big. When I tried to reboot the phone it was the same. The fastboot was no longer accessible. I put the phone into servis but they didn't fixed it. it's the same but I can enter erecovery

Please flash only files for your device and nothing else. Did you try dload method?
