1. Thank you rodlane for all the help. Finally it worked.

2. I had B313 but in the update.app to extract I had only boot.img and recovery.img

3. I had also B321 full, so I extract boot, recovery, cust and system from that one and flash them in this order.

4. I put the file that you send on sdcard and follow the procedure to update. At 5% failed but after reboot, the phone turned on just fine, with android 6.0.0 and B321 on it. Everything is working just fine

Thank you for your help.

Cheers

I just want to say thanks for your post, I've been trying to unbrick my phone for four hours and finally managed to do it with your help!
[Huawei P8 Guides, News, & Discussion] ivanpilev:
Hi guys. Thanks for your help. I was stuck in bootloop after tried to flash to B321a from b200 with twrp (very stupid I know). I immediately stuck with bootloop. I reflashed boot and recovery from b200 and I can boot to my device again.

I want to try this guide, but I have one problem. I didnt have B200 version, when my phone get bricked, but I had B132 version. So, which version I have to install? Thanks :)
[Huawei P8 Guides, News, & Discussion] Vladicostea:
Just try that! It can't get worst if the phone is bricked
[Huawei P8 Guides, News, & Discussion] TopperBG:

i'm unable to load EMUI, already tried with B151,...

Any help?

When trying to flash system system.img i cant waiting for device and it doesn't doe anything :(
[Huawei P8 Guides, News, & Discussion] TopperBG:

[Huawei P8 Guides, News, & Discussion] KRiST0F:
unbrick it if it is even bricked, i've a constantly booting phone.

it goes like

*Vibrate*

huawei booting logo

dark screen

*Vibrate*

=> repeat
[Huawei P8 Guides, News, & Discussion] TopperBG:
So, you are NOT on B321, just tried to flash it?

What was your previous ROM?

From that one you should flash boot and recovery and after flash it - force upgrade with 3 buttons.
[Huawei P8 Guides, News, & Discussion] KRiST0F:
in fact, i was on 321, installed twrp (http://xdaforums.com/android/development/guide-install-twrp-root-systemless-t3325161) modified one.

it wend good even was able to boot in to recovery (twrp) but after flashing the supersu zip file he wend into continious rebooting.
[Huawei P8 Guides, News, & Discussion] TopperBG:
I'm lost....
[Huawei P8 Guides, News, & Discussion] KRiST0F:
we've updated the phone yesterday to 6.0 (MM) [B321] update itself was ok.

however when rooting it it went to bootloop.

---------- Post added at 04:32 PM ---------- Previous post was at 04:27 PM ----------

to fix that i thought i'll go and use this guide. cause i can go to emui (original recovery but i only can reboot, use erecovery (wifi) or shutdown)
[Huawei P8 Guides, News, & Discussion] rodlane:
Flash the boot.img from b321 through fastboot. Now try rooting again. Remember to enter twrp in read only mode and execute the terminal command before rooting.
[Huawei P8 Guides, News, & Discussion] KRiST0F:
oeps, i think i didn't do that last twrp in read only and exec. terminal command. :( can i undo this?

i've just tried: entering twrp, used the command and installed su again.

Now i'm not in a bootloop. But i have that huawei logo (flower) with a glow on it
[Huawei P8 Guides, News, & Discussion] rodlane:
Flashing the boot.img from b321 is the part that resets the failed root.
[Huawei P8 Guides, News, & Discussion] KRiST0F:
OMG! it worked however now it feezes on installing update (5%)
[Huawei P8 Guides, News, & Discussion] rodlane:
What update are you installing after already having b321?
[Huawei P8 Guides, News, & Discussion] KRiST0F:
i got it working went into recovery mode, and strangly i was able to wipe cache. did that, restarten phone while vol up + vol down and he was updating.

everything works now even rooted. Xposed wil be a challenge for this weekend, hopefully then i get the smartcover working.

[Huawei P8 Guides, News, & Discussion] TopperBG:

[Huawei P8 Guides, News, & Discussion] srdjan979:
The problem is that I can not get into fastboot mode because it is constantly enters the recovery whatever you do. The phone can not be switched off completely when I hold the button to switch off only restarts and I enter the recovery to be frozen.

[Huawei P8 Guides, News, & Discussion] TopperBG:
Plug-in into computer and keep pressed vol- and.power even after 1-2 reboots - will enter fastboot.
[Huawei P8 Guides, News, & Discussion] rodlane:
Try to get into recovery while your phone is plugged into your pc. Keep holding the buttons down until you see your screen turn on. That 'might' get you into the bootloader.

This is also dependent on which rom you have on your phone.
[Huawei P8 Guides, News, & Discussion] TopperBG:

[Huawei P8 Guides, News, & Discussion] rndll:
This can be caused by a few things:

1. Bootloader is still locked.

2. Issues with USB Debugging (try turning it on/off)

3. You are not running the command line in Administrator mode.
[Huawei P8 Guides, News, & Discussion] Axims:
Can somebody please explain to me how to extract recovery.img and the rest from update.zip ?

because there is huge system.new.dat a boot.img which fastboot says it's not a proper image and 3 folders: custom meta-inf and sig. and of course some other files but no recovery.img

i also obtained a sp flash friendly rom which again, fastboot cant use them. the source was not 100 per-cent trustable so i'll assume those images in there might be corrupt .
[Huawei P8 Guides, News, & Discussion] rodlane:
You need to extract the img files from the update.app file of a full rom.
[Huawei P8 Guides, News, & Discussion] Axims:
OK, but these huge zip files (1.5GB) are all there is on huawei download pages. with structure I described above and NeedROM doesn't have any, yet. so is there a tool maybe, that can be used to convert these "update.zip" to "update.app" ?

tnx
[Huawei P8 Guides, News, & Discussion] TopperBG:
Yes, there is Huawei Update Extractor for that. Search in forum.
[Huawei P8 Guides, News, & Discussion] rodlane:
Update.app is inside the zip file. You need to extract it on your pc and use the tool that TopperBG mentioned.
[Huawei P8 Guides, News, & Discussion] Axims:
This is inside zipped ROM :

inside dload :

inside dload.zip :

there is no update.app here .
[Huawei P8 Guides, News, & Discussion] TopperBG:
So put whole dload folder in your sd card and proceed to update.
[Huawei P8 Guides, News, & Discussion] Axims:
I wish it was simple as that. phone's recovery gives error right after starting to apply new rom because recovery I flashed is from Chinese sku (which has no GAPPs) . I've found the right sku rom but there's no recovery.img in it. hence, asking for how extract the recovery from update.zip.

here's the rest of the story : http://xdaforums.com/showpost.php?p=66945639&postcount=39
[Huawei P8 Guides, News, & Discussion] TopperBG:
I see, that was my way to resurrect bricked phone. So you must find full, not update ROM. There's update.app with images of partition. If you can't find, please tell your sku and needed version, could have that recovery.img
[Huawei P8 Guides, News, & Discussion] Axims:
It's a Y6 Pro (which is the global version. other aliases are Enjoy S [china only] and Holly 2 plus [India] )

this is the correct rom : TIT-AL00C328B123 ( which I have but, it's in SP Flashtool scatter-txt format) :

P8 boot loop

Hi

I have a following situation:

I was upgrading my phone to Marshmellow with TWRP (too old version and yes, only upgrade on stock ROM, learned hard way) -> in a boot loop now, so I can't use phone at all.

I can only enter fastboot & rescue mode (fastboot & rescue mode, phone unlocked with white background & android logo):

C:\adb>fastboot devices

S7M7N1570200xxxx fastboot

But every time I try to flash fastboot (anything) phone gives response:

(Files extracted from B200 UPDATE.APP, which was original ROM)

C:\adb>fastboot flash boot boot.img

target reported max download size of 471859200 bytes

sending 'boot' (23270 KB)...

OKAY [ 0.498s]

writing 'boot'...

FAILED (remote: Command not allowed)

finished. total time: 0.513s

How can I proceed from here in order to be able to flash old ROM or boot.img & rescue.img?

Help really appreciated, read the whole thread, but rather confused and could not figure out the solution...

Edit: Fastboot flashing unlock gives the same response, also B200 version from where the files were extracted was probably full (2,9 G)

-Proxxis

Edit2: Solved: Misstyped "Fastboot oem flashing unlock xxxxxxxxxx". After this, boot.img & recovery.img flashed ok. Finally, vol up & vol dn & power boot -> upgrade from SD card worked normally.
[Huawei P8 Guides, News, & Discussion] ebbytay:
Hii,

I have a similar problem as you do but slight different is that i deleted the rom and not try to upgrade.

You said you solve the issue by flashing the oem, but mines is already unlock and i still get the error, but i am about to try the dload method. For this to work do i have to flash the boot.img and recovery.img?
[Huawei P8 Guides, News, & Discussion] Proxxis:

[Huawei P8 Guides, News, & Discussion] d0v1k:
How to fixed the Huawei P8 GRA-L09

This is how i fixed mine.

First thing you need to do is unlock your bootloader

This is what you will need:

PRODUCT MODEL: HUAWEI GRA-L09
SN :
IMEI :
PRODUCT ID:

If you dont have your PRODUCT ID download Huawei Hacker Toolkit v1.4 with the link below

generate one with your Product Model and Product IMEI.

www82.zippyshare.com/v/NJBTgAJP/file.html

The English version of the huawei website to unlock the bootloader is not working the verification image code doesn't load.

The Chinese one is working use google translate to register or open the English one to see where to click.

emui.huawei.com/cn/plugin.php?id=unlock&mod=detail

After Unlocking your bootloader download this firmware:

download-c.huawei.com/download/downloadCenter?downloadId=59627&version=193861&siteCode=jm

Use Huawei Update Extractor to Extract recovery.img, boot.img, system.img, cust.img from UPDATE.APP then flash with fastboot:

www82.zippyshare.com/v/RdqlRhk9/file.html

fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot reboot

Last step download:

GRA-L09_C432B317_Firmware_Europe_Android6.0_EMUI4.0

download-c.huawei.com/download/downloadCenter?downloadId=72708&version=257321&siteCode=es

extract zip then copy dload folder to to external sdcard

Make sure your handset is power off. Insert the Micro SD card into the handset.

Press the VOLUME UP and VOLUME DOWN key, and then press the POWER key to power on the phone and enter the Software Upgrade Mode.

When the progress bar stop, the phone will restart automatically.
[Huawei P8 Guides, News, & Discussion] one_million:
I'm done with mine too :)) simple way. installed this rollback from this site http://www.huawei-info.de/p8-mm-rollback

extract this zip. put update.app to micro sd dload folder. load phone with three butons function. install this update. then rr straight to recovery. do factory reset. then another micro sd with full firmware ......B200. again load phone with vol-+and power. install. both installations ended with failed at 95% but don't worry everything is OK. Just after any software installations when phone restarts go straight to recovery menu and do factory reset and cache clean. after that when phone booted to android. clean your micro sd card and put full 321a firmware (update.app to dload folder) go to settings>update>forced update and lounche update from micro sd. phone rr and starts android 6 installation. failed at 95% but don't worry ;) all done! Enjoy your new android ;)
[Huawei P8 Guides, News, & Discussion] AscalonX:
OK, I've read all the methods here and I'm stuck in a different way.

GRA-L09. I downloaded the OTA update (the 400 oddMb one, not the full image), as per a tutorial and put it in the dload folder on the SDCard. I did the local update form the settings screen and the EMUI update screen came up and it installed 100%, but now I'm stuck in the boot loop.

However, my issue is that the phone will not respond to any variation of the three button start.

It will not power off at all and only stops the boot loop when it is out of power. As soon as I plug it in to a USB port or just the charger, off it goes again in the uninteruptable boot loop.

I've tried volume down + power, volume up+ power, and both volumes + power to no avail.

Is there something I'm missing?

Cheers
