I have boot.img and rocovery.img from B118 General, and system.img form B200.

I don't have sounds (any calling, multimedia, notifications), to charge I have to switch off phone, system restarts when try to uninstal something... but system works, and phone is somehow usable (GPS, NFC, WiFi, LTE, Bluetooth working).

Still can't local upadte any full rom, or upadte rom, so I'm waitting for update higer then B313, or mayby any solution to back to B200.
[Huawei P8 Guides, News, & Discussion] TopperBG:
I'll say you once again - don't try older and oldest boots and recoverys.

Try first (and second and third some times) with THAT firmware, which update leads you to bootloop.

With older parts from ROM can solve 5% of update crashes/bootloops.

When you flash boot and recovery from B113 and you system partition is still B200, that can't be good and bootable. You can mess a lot of things with that way "tail of the horse, trunk of the elephant, neck of giraffe"
[Huawei P8 Guides, News, & Discussion] lesiot:
I know... but for now it's only way to use phone at all (witout calling, but sms, internet works).

There is no way to get B313 boot+recovery and B313 system.

B200 boot+recovery+system is useless, because you can't even turn off the phone, only bootloops till battery live.

Trying update every single day witch B313 boot+recovery, and not working system will not (can't) change anyting. I think there is no reason to try second, third or more.

Mayby Huawei give, a package to downgrade, like package for P7 (Downgrade_P7_L10C900B830 ->P7-L10C900B800).

For now I flashed mix (2 dasy ago) like I had wrote earlier, and nothing going to change until huawei release next rom, or solution.
[Huawei P8 Guides, News, & Discussion] TopperBG:
1. Flash boot & recovery from b313

2. Save to /load FULL b200 update.app

3. Initiate update with 3 buttons.method

Hello everybody.

Now I have on the hands a P8 (GRA-L09) but I don't know is it's branded or where it come from (Hungary, Greece, ...) because it's of a customer.

The phone is soft bricked after an update (I don't know which version was on the phone) and I can access only in fastboot mode or I've a bootloop.

Now, I've tried to install B110 and B132 from the official Huawei website. I've also tried B170 and B200 but they didn't work!

Have I to try all Bxxx firmware or can I get some info from fastboot?

Thank you in advance :D

Bootlooped phone cannot retrieve Product ID

Hi all,

I have read through the whole thread and there is one answer I'm missing:

I cannot unlock my P8 since I do not have the product key, without that, there is no way it seems to get the Product key which you need to unlock the phone using the Huawei site.

There's this link where a guy explains the whole process nicely, except the Product ID Generator doesn't cater for the P8!

Please tell me how to get the Product ID on a bootlooped P8, because without that I cannot flashboot the device.
[Huawei P8 Guides, News, & Discussion] Adnan989:
So I hope that this will help because it solved all my problems and i had a few of them :D

1. no network no imei no baseband

2. recovery mode restarts after a few seconds

3. system install failed wrong version

I think the best way to fix those problems and ofcourse the brick and bootloop is the next.

CHOOSE YOUR SOFTWARE VERSION my was the B200 for Europe DOWNLOAD THE FULL VERSION

USE HUAWEI UPDATE EXTRACTOR to extract the files (BOOT.IMG RECOVERY.IMG CUST.IMG SYSTEM.IMG)

NOW IT IS TIME TO USE FASTBOOT (VOL-PWR BUTTON) YOU WILL NEED FLASH FILES IN THIS ORDER

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash cust cust.img

fastboot flash system system.img

fastboot reboot

NOW YOUR PHONE WILL TURN ON AFTER A FEW RESTARTS but no network maybe wifi it depends on your software version

NEXT YOU WILL NEED TO DOWNLOAD THE MARSHMALLOW UPDATE version for my phone was B313 and put the UPDATE.ZIP in DLOAD folder on the SD CARD then press VOL+ VOL- and PWR button it will start the update and install your system then do phone reset and everything will bee fixed

Vodafone Branding P8 - tried do debrand and got error message like in the description. Ignored it like I was supposed to and tried to update to Android 6 Beta.

From that moment on I had a bootloop.

My bootloader is LOCKED.

Every firmware I tried to do with three button (Power + Vol+ and Vol-) bring me to EMUI, but it will either stop at 0% or it will say incompatible firmware. I put the UPDATE.app files in the dload folder with different SDCARDS.

I cannot do anything with fastboot since the bootloader ist locked.

Any ideas would me more than welcome.

That ist how i did it, maybe the problem ist, that my firmware was B120 vodafone. So I have a total mess now. I cannot update to B170 without branding NOR B200. Phone says, it is at B200 now, but even normal wipe from system leads to an error. So I would need an untouche full ROM with wipe and stuff. It will not work with 3 button mode. Neither will it from EMU Updater. Emu is on 3.1

Stuck with no network after fixing Marshmallow bootloop

Ok, so I posted previously that I had success with the P8 after unsuccessful Marshmallow upgrade. Not altogether though, the phone now starts up finally after a few restarts, but it doesn't recognise the SIM, otherwise it seems to work fine. I still can't believe nobody knows how to do a low level wipe and install a full version? Is it really impossible?

My phone is rooted, but any up or downgrade or wipe or fastest flash still leaves some files that are causing problems.

C'mon all, somebody must know how to do that?

If you are able to install a custom recovery, do it and format the cust partition. Then go back to the bootloader and flash the b170 recovery, and flash the b170 cust.img. Now flash the full b170 again. Then b200. Then b313.

I am assuming that you have the patience for all of this :)

No matter what files I use with fastboot (like described here boot.img and recovery.img) it doesn´t work with B170 or B200 boot.img and recovery.img files.

The P8 will boot, WLAN works, it still has no IMEI. Typing in the callpad the numbers #+#+----+#+# doesn´t show up the engineering mode. Just nothing.

Software Update B170 or B200 or whatever will NOT start. It just stops at 0%. No matter what firmware i put in SDCARD/dload folder. Local update finds package, rebooting and says error.

fastboot flash cust cust.img

fastboot flash system system.img

But it is also locked. And I have only the IMEI since it is printed on the inside of the sim card drawer.

And I can't get them because the device is bricked... and the box is long gone.

You can try calling the place you bought your phone from. They might have the serial number

Update: The rollback update.app actually starts, breaks at 95% with failure and headset still no IMEI / basenband. Tried to flash Marshamallow again, won´t even start the update.

Now every update (B170, B200) I try to start breaks at 0% - incompatible software. Any ideas on that one?

Update II: After fastboot cust.img from the rollback package the phone accepts B200 via 3-button forced update.

There was something with the USB connect. Must USB has to be pluged IN or OUT during the update (I read somewhere update stops at 90% otherwise)

IT BREAKS - Incompatibility with customization information - please download the correct update package- But which? I am frustrated.

THE GOOD SIDE: IMEI is back!
