[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!

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.

Booting to fastboot but how?
Hold volume down and power button simultaneously until you see a white screen with android logo and "Fastboot & Rescue Mode"
you will also see whether your phone's bootloader is locked or unlocked,if locked then you have to unlock it from Huawei website before flashing any thing

How to solve custom recovery not installed after flash on all smartphones[Tutorial]

Hello . A few minutes ago, I had a problem with the TWRP flashing on my huawei p8 gra-ul00 phone .the adb has command's the twrp is complety flashed on my phone , but it did not come up on my phone(after pressing vol+ and power button's the phone will automatiocally go to huawei erecovery). But I took a little initiative and came up with a solution to this problem. I'm share this.
NOTICE : IF YOU HAVEN'T A USB DATA CABLE , PLEASE BUY IT , OTHERWISE CONTINUING THE STEPS WILL NOT SOLVE YOUR PROBLEM .
Before completing all the steps, connect the phone to the computer using data usb cable, then try to enter the recovery mode (for Huawei phones, hold the power button simultaneously with the volume down button for at least one minute.) If the phone Entered custom recovery, no need to do other steps.
1_First Of All , Unlock the bootloader , then reboot the phone
2_Download the custom recovery . IF YOU HAVE ISN'T A CUSTOM RECOVERY FOR YOUR PHONE , PLEASE SEND A COMMENT AND ENTER YOU PHONE MODEL AND A NAME OF THE CUSTOM RECOVERY YOU WANT TO USE TO IT. IM WILL SEND A REGUESTED CUSTOM RECOVERY FOR YOU IN LESS THAN A HOUR .
3_connect the phone to computer and Enable USB Debugging from Developer Options(go to settings>about phone , then 7 times tap on build number , then go back to settings and select developer options , search for "USB Debugging" Option and enable it.)
4_, install the adb and fastboot drivers(such as minimal adb and fastboot) then install the phone drivers . after installing drivers , reboot the computer , then open cmd and enter the command : adb reboot recovery
5_if a window showed on phone(such as allow usb debugging) , click on yes and retry the level 4 again
If you have any questions or problems , commend here.

Hy Bysoft!
I'm new in XDA but i alredy flash some devices with TWRP, it seems that something went wrong with the installation of twrp. Did you try to boot into bootloader (adb reboot bootloader) and then flash the TWRP image with fastboot (fastboot flash recovery twrp.img) and then type fastboot reboot?
I find that list of command: adb reboot etc.. in your device page of TWRP (https://twrp.me/huawei/huaweip8.html). In this site you find the TWRP image for your device, you have to use this image when you flash with fastboot (fastboot flash recovery twrp.img where twrp.img is the image that you downloaded in TWRP site).
