Huawei P8 Bootloop - Huawei P8 Questions & Answers

Hi guys!
I have an issue here with the Huawei P8. I wanted to go back to stock from ARROW ROM, so
-I used Huawei Extractor to get the stock recovery and flashed it via fastboot adb
-Updated my phone with the 3 button method and put the DLOAD folder into my SD card
-I used B394 to get the recovery img and to update as well (it was ~1,6Gb)
The update started and everything worked fine, the phone said everything is fine but my phone stuck in bootloop. I mean it doesn't restart or anything but all I can see is the Huawei logo.
What should I do? Any tips how to fix this?

First try getting into Recovery mode & doing a factory reset & cache wipe.
If that doesn't work, try with a stock rom that's one prior to what you had before installing Arrow - like in this thread & follow the steps there (i.e. you first need to flash boot, system & recovery .img files extracted from the prior rom): [GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop
If you cannot find where to download the prior stock rom, ask for help - someone may be able to provide a link that works. Tell us your phone's full, original model number (GRA-????), the region rom you need (e.g. C432 would be European) & the version B???.

Softbricked phone, no idea how to proceed

EDIT:
It seems since there is no Huawei P8-Subforum, my thread seems to has been postet to misc. Development. Im sorry about that!
Hello there,
I spend the last three hours trying to get the device (L09) to work again. I made the terrible mistake to update my phone with custom recovery (TWRP) installed. My target is to upgrade from B191 to Marshmallow.
The main probleme here is that I don't own a micro-SD card plus the internal storage contains a dload-folder which I can't delete.
My current situation:
- The phone is bootlooping at bootanimation
- I can access the fastboot-mode, stock-recovery and upadte-mode
- My internal storage (intenal SD-Card) contains a folder named "dload" with the B200 firmware
- I flashed the stock B200 recovery.img and boot.img (extracted with Huawei Extractor)
- When going to update mode the phone proceeds to 5% and then shows "Software install failed!"
I don't really know how to proceed from here on. I tried to flash TWRP again to clear the dload-folder and place another firmware, but somehow twrp can't be installed anymore - flashing shows "OKAY" but when booting into recovery, the same old Huawei recovery is booting. Also I'm confused as to when to leave the USB plugged in or disconnect it.
My current plan is to revert to 170 firmware to start completely over. I downloaded the 170, 200 and 313 firmware.
How to proceed?
EDIT:
I flashed recovery.img, boot.img and system.img from B170 and now the boot repeats at the Huawei logo. After flashing boot.img and recovery from B200 I get to the bootlogo again, which is stuck.
Solution:
After flashing boot.img from B191 the B170 firmware booted successfully. I got a few random reboots at the start, but they quickly grew less and now I have a somewhat stable B170.
Upgrading to B191 or B200 didn't work, tho. I'm trying to get behind that now.

Help unbricking my huawei p8

Hello everyone, I have a huawei p8 vodafone it branded.
I decided to root it, unblocked the bootloader and everything was good so far...
I tried to flash a custom recovery but failed for some reason and I decided to stick with stock recovery.
Now I installed an app as system app and my phone got bricked. my fault..
At first It went trough a bootloop and I was not able to access the huawei recovery or the fastboot, after a while it started to boot into a error message where it was saying that it was impossible to read user data partition, and give me some choices like backup, update to the latest version, or data factory.. I choose data factory twice but it went trough a bootloop again only to give me back to the same page after a while.
I can access huawei erecovery but it gives me getting info package failed when it says that I have to update it with wifi.
I can access fastboot mode and it says me that the phone is unlocked.
I really don't know what to do as I'm not expert, I tried to read various topics but never saw anyone with this message where it was saying impossible to read user data partition..
I had emui 3.1 5.1.1 with vodafone it brand... In case I have to flash it which firmware I should look for? Or is there a way to get my phone alive again without flashing?

Hey thank you silvano, can you tell me which firmware I need to flash it? Is it okay if I use a b170 even if I had the 5.1.1 emui 3.1 version?
Nothing, I can't seem to make it work, I've flashed the boot.img recovery.img system.img and cust.img successfully(b170) but still stuck in bootloop, I can enter bootloader mode, and recovery.. but when I enter recovery it says me that I need to update it and I can't update it because it says me that getting info package failed... tried with different wifis, same result..... The excatly same thing happens with the b132 stock rom too and I cant factory reset or even wipe cache if I dont make this update first as is the only option avaible on huawei eRecovery.
As last attemp I tried to force an upgrade with putting UPDATE.APP inside the sdcard and press vol up vol down and power for booting but this combination of buttons doesnt work...
I'm hopeless, I really don't know what to do... any help would be much appreciated

Restore baseband and imei to make sim work again

Hello everyone.
I rooted my phone (os was marshmallow) with android lollipop procedure, so i soft bricked the phone.
I flashed with fastboot various versions of huawei p8 lite firmware, all of these were 5.0.1.
When I managed to unbrick my phone I found out that it can't read the sim, so I looked in settings and IMEI and BASEBAND were disappeared.
Probably direct downgrade from marshmallow to lollipop caused this.
By the way, I managed to solve all my problems.
I will write what I've done here. I hope will be helpful. To start: my model is ALE-L21 (Single Sim).
- Download B041c (if you search in google you will find various results, all taking to the same site). I'll explain this better after *
- Flash with fastboot B041c
- Download B133 (this is very easy to find, but if you have problems search in a site called carbontesla)
- Unpack B133 dload folder (you will find custom folder too, don't worry about it) and put dload folder in the root of your sdcard
- Go to Settings -> Updater -> Local Update and start B133 update. Phone will boot. The upgrade process should be done with phone chargend and unplugged from PC.
- At some points update could appear stucked (for me was at 15% and 85%) but be hopeful and it will continue (let be patient).
- Phone will boot and your sim after 4-5 seconds will work again!
* B041c is hard to find. At this time only one site have it. I can't link you this site, because the downloader you get from this site installs adware on your pc while it download B041c. I have had to solve my problem so I proceded at my own risk.
Updater will notify you about the update to B183. It doesn't worked to me! If you want to update your phone you can install firmware B171 and install it as update (in dload folder)
UPDATE TO MARSHMALLOW
- If you want to update your phone to marshmallow you have to download other two firmwares (B171 and the MM you want. I used B551)
- Put the dload folder of B171 in your sd card, turn off your phone and force flash (VOLUP + VOLDOWN + POWER buttons). It may appear stucked at 19% and 85%. Don't worry, be patient!
- When phone boot is completed, put dload folder of your MM firmware in your sdcard, turn off the phone and force upgrade (VOLUP + VOLDOWN + POWER buttons). It will take 15-20 minutes.
- When installation is completed and phone boots, turn it off again, enter in recovery mode (VOL UP + POWER button) and clear data and cache.
- Now you have a clean install of MM! However, some applications may be old (play store). If you have connected our phone to a network, play store will update automatically
SOLVE BALONG BUG
You can find easliy the solution in the forum. But to be a complete guide and make your life a lot way easier here is the solution.
Simply put UPDATE.APP of custom folder that you can find in some firmware (I used B049 custom folder) in your sd card and then update from settings or from force update. Is a 20KB file so it will be very fast to install

Hardest Bricked my P10 Plus. Can't even turn my phone off.

Thanks again to @Blackball and rest of you guys, much appreciated for your help.
What on earth is Yoroot?
So, You can't enter fastboot mode am i right ?
Do you connect usb cable to your devices before press Vol- and Power button ?
Current Situation
After the battery was dead, i actually can enter the fastboot and i used TWRP 3.1.1 for huawei P10 Plus from github. double wiped my device and by far i have entered the system normally.
However, the ROM wasn't official and i lost my warranty for unlock my huawei phone. And the custom service from Huawei said that they don't provide any official ROM Since it's Android 7.0 .
This ROM is really crappy that i can't delete/uninstall any Application i installed.(It gets reboot everytime i try to and the Application is still there even i just tried to Delete/Uninstall).
Worst of all, some options does not work properly in "Option" menu . (For example i can't access to "Developer mode" that everytime i press it it tabbed back to the former menu.)
I really hate this crappy menu so i tried to search on the internet for P10 Plus ROM so far i get B133 update ROM i can find and i tried to install it from SDcard by pressing VOL - and VOL + and Power buttom.
It says failed to update system at 5% while updating/recoverying the system.
and the ROM which i'm using was found in HUAWEI's official fan forum from Club.Huawei.com a forum belongs in china.(Rooted rom B140).
Right now seems the only option for me is to find a better ROM than this .(At least won't get me so many bugs like this one .:crying: )
and Thanks for your comment "Bigbearxl" it worked as normally it should after the battery was dead then i recharged it.
Yet Right now the PC doesn't recognize the device though Via-Usb because it's not Huawei official ROM and Hisuite helper only recognize their own ROM and the rest Phone helper or ADB can't recognize the device while The Phone is Booting normal .
And Reply to "Craphead" Yoroot is a special Root tool for Huawei P10/P10 plus made by chinese from Huawei Fan Club forum.
New Update
After rewrited boot.img though fastboot mode from https://forum.xda-developers.com/p10/help/root-huawei-p10-p10-t3589946 thanks to "yury_z, " i can start to delete files with current system, but it's still crappy that it doesn't even have camera
So i think i will try dload method to recovery my phone with firware that i found in forum.
Failed
Looks like i have to stock with that bit longer
dload with update.app method failed. and recovery TWRP install missing md5.
Unless i get System.img or i guess i can't get another system.:crying:
This work for P10plus too

Maybe you could also try installing stock firmware with funkyhuawei, it's not for free though. But dload method never works on P10/plus unfortunately.
thanks @Blackball and @Craphead. i checked both of your method but didn't work and this new twrp 3.1.0 i downloaded displayed sd card 0mb. and i followed poster's step and missing one file.
However i might found a useful Thead that might work and i'm gonna try tonight.

That is what I wrote.
It seems that firmware finder work for P10/plus now.

@Blackball not sure you what you mean by that, do you mean that you can actually use it to install firmware on p10/p10 plus now? If so how did they manage to get around the authentication issue?
I debranded my phone from L09 to L29 DualSim with this guide. It work with moded stock recoverys.

well i tried your method but there were some file that can't be downloaded from that post so i used another and,eventhough with complete files, the method i posted and i was going to use it tonight. Failed.
did all the steps from update.bat indicated and all worked fine till the last step that it says " automaticly install system" and the phone shows error at recovery.(similar to dload method because it automaticly create dload and exact those ROM files)
it indicates a big red " ! " sign and stopped. basicly i'm back to "No System Status"
The only method wowrks for my "P10 Plus" is " flash system system.img " method.
yet i don't know how to exact system.img boot.img recovery.img etc from those stock firmware like those chinese.
i have some of their rewrote roms (it's crappy because i has no default camera and it's for chinese P10 Plus A.K.A VKY_L29) .
Yet i can't find any System.img on google by far.

I haven't tried your Firmware Finder method , i think i can install crappy system.img then try your Firmware Finder method.
Because right now i wiped my system and i'm without system :crying:
Guys This Thead https://forum.xda-developers.com/showthread.php?t=2315547
tells you how extract flashable rom files from firmware update.app.
It should work but i only made to Unknownfile XX .img and i can't download his script "HuaweiFinder" from his google drive.
Holy Crap it worked, i Extracted system.img and other img from update.app by some Chinese scripted unpack script. and I'm trying to restore my device though fastboot mode with adb.

well just tried your method and at last step it says installing failed. then i reboot entered rec mode choose wipe/factory reset
wiped till 50% and stopped, it can't factory reset.
Before this method fastboot mode was " Phone unlock " " Bootloader unlock."
Now it's just "Phone unlock"
now i'm stuck at boot loop "your device is booting now" then it rebooted and back to "your device is booting now" again then automaticly goes to Erecovery mode. I have to shutdown device for now and hope i can find some solution tomorrow :S
When you try this :

It's important that you have the 3 zip files from your wanted firmware and rename them correctly. Don't mix with another firmwares.

In recovery mode i tried to wipe data/factory reset. It stopps at 50% which is after wipe and starting to factory reset at 50% it failed.
i try to flash in system.img and boot.img yet i still can not enter the system and stuck at bootloop.

PLZ HELP ME Mate 9 Pro LON-L29C636 brick

I accidentally wipe Dalvik/Art cache、System、Data and Cache through twrp recently.
Now, my phone shows no OS, so can not boot in system.
I can enter TWRP and fastboot and e-recovery, but I have tried to install UPDATE.zip, it always show error. I can install update_full_LON-L29_hw_spcseas.zip sucessfully though.
Is there anyway to fix my brick mate9 PRO>< PLZ help me
Another problem is that I cant install zip files through install(my phone doesnt have a sd card), the directory always shows encrypted text and wouldnt let me choose. I have tried few recoveries, including TWRP_3.2.1-0_OREO, Rayglobe_Recovery, and twrp-3.1.1-0-hi3660. Some of them cant getin recovery after flashing them, the rest shows encrypted text. Can anyone please save my brick phone?
TWRP doesn't work correctly, since the phone uses encryption.
I'd try downloading the Huawei Multi-tool, then download a full update through it, that fits your phone model. Then (assuming you have access to fastboot) flash the downloaded update through the Multi-tool program.
Basically this:
Huawei Multi-tool > find correct firmware with Huawei firmware finder (it's included in the program) > extract the different parts of the firmware needed, which is displayed on the the unbricking tap, and follow the rest of the instructions displayed there.
