You will need to flash the stock recovery in the same way that you flashed the TWRP recovery. So the way I would do it is connect phone to laptop..then use command
"adb reboot bootloader"
Then when your phone is in bootloader mode and with the stock recovery in the same folder as where fastboot and adb are use the command
"fastboot flash recovery recovery.img"
And replace recovery. img with the name of the recovery u want to flash.
Then reboot and you should be back to stock
I am on L09 but if you want I can upload my recovery
Edit: I found a stock recovery file in a thread, this is the one I used on my L09 - READ THE COMPATABILITY WARNING BEFORE FLASHING AS YOUR OWN RISK

Thank you, but your recovery is the same with mine UL00 ?

I dont know the answer to that. I updated my post above with a link to L09 recovery
Alternative is you need original stock rom to extract recovery.img from

I've just figured out a way to get the recovery for you, if you give me about 1 hour I will extract the recovery.img from UL00 Stock B120 (Lollipop) firmware and upload it

I have the original stock rom from here http://www.needrom.com/download/ascend-mate-s-crr-ul00/ .Now I have to found how extract the recovery.img

Thank you very much.

I'm just downloading the B103 stock ROM.
If you want to try you can see how here
http://forum.xda-developers.com/showthread.php?t=2433454
https://www.youtube.com/watch?v=Z3rw78gAl3k
Make sure the ROM you have is the full ROM and not the update because the update might not contain recovery.img

The B103 is CRR-UL00 . Because i saw CRR-UL00-C00B104-unicom.zip. It is the firt at needrom.com

I'm struggling to extract the recovery.img - I keep getting a CRC Error.
Is it working for you?

If I install UL00 B144 the latest I found is it posible to return on original recovery ? But I don't know how to install , it is posible with TWRP.

I dont think you can install without the stock recovery...it doesnt work with TWRP

Hello my friend brumgav I download-- CRR-UL00-C00B104-unicom --. I use the- -HuaweiUpdateExtractor_0.9.9.3-- I found Recovery.img. I have to install it with -Minimal ADB and Fastboot- and I am OK ? I used the -Minimal ADB and Fastboot- for installing the TWRP.

extract the recovery.img from your current update.app. then flash the img-file like you flashed the twrp recovery.

OK I did it
1. I use the- -HuaweiUpdateExtractor_0.9.9.3
2.I found Recovery.img and I flash like the TWRP and everything is OK.
Thanks everybody.

you need the working OEM-Unlock option in your settings or an TWRP backup without FRP-lock.
even with TWRP recovery you can´t flash anything with adb/fastboot while your device is FRP Locked.

Question about converting Chinese version (EVA-AL00) to international (EVA-L19)?

I know something like this was asked before , but i've got confused and need help with that .
i have Chinese Dual sim version EVA - AL00 and i want to convert it to international dual sim version EVA-L19.
Is that possible ?
I've unlocked bootloader , i also found Software for L19 (all needed files : recovery, boot, userdata, firmware) . i even found Nougat (android 7.0) firwmare ..
So , can i cross flesh them ? and how can i do that?
L19 firmwares
http://huaweidevices.ru/category/huawei-p9-eva-l19 (marshmallow files)
http://www.gizrom.com/android-7-0-emui-5-0-huawei-p9-eva-l19-2/ (nougat files)

*#*#2846579#*#*
And then update from sdcard doesn't work!

use adb/fastboot to flash system, boot, cust and recovery image from L19 marshmallow and next flash with sd card method nougat update

I'm almost ok with this rom too , but if there is a chance...

Yes and thats all and after flashing make factory reset

Hmm , you did that before?
i mean in theory i understand it's possible and i did something similar to other brands (like htc m7) years ago , but don't really want to brick this one , because i really like it
anyway what's order ?
1) fastboot flash recovery recovery.img
2)fastboot flash boot boot.img
3) fastboot flash Userdata ?? (don't think i've ever used this one before)
4) fastboot flash system update.app
this one confuses me more then others, because there is only "update.app" and not system.img or something like that ...

Ok so i've bricked it , because fastboot flash system update.app didn't work because of error
"targed data reported max download size ..."
no i'm just waiting for huawei Erecovery to download file

Install Adb/Fastboot, download lastest Marshmallow ROM for L19, download and extract Huawei Extractor, extract update.app with Huawei Extractor(system,boot,recovery,cust image), connect phone to pc with enabled debugging and flash images with commands :
adb reboot bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot reboot
After flashing make factory reset.

Huawei Erecovery reinstalled software with no problem, so there is still a chance..
I was excepting exact that thing .
now our goal is to find system.img or fastboot command to flash update.app , installing boot and recovery was quite easy and had no problem with it after i unlocked bootloader (again)

I've unlocked bootloader
then connected phone with fastboot mode (power off , then Vol down and plug usb)

i just need to flash system.img somehow and it will work ...

I wanted to try changing oeminfo and then flashing again , but after flashing firmware with Erecovery , it relocked bootloader and i don't really want to got same processes again , i mean unlocking bootloader will reset device and i'm tired of removing HIXX crap and installing google things (esspecialy contacts)
if there is at least 90% of chance with flashing L19 firmware , then i'll do that , but for now i think i'll stuck with this , at least for some days

Anyone with more info about this stuff?

I did converted AL00C00 to L19C432..... Everything working fine.... Anyone interested.... I can share.... It z quite simple....

Hi, could you share the steps to do the conversion.? Many thanks

Any one with a rooted vie-l29 l09 or al10 can help

Hi
i need the misc partition backup from any working p9plus
My vie-l29 was bricked and to unbrick it i used a factory board firmware of an al10 that erase all partition and recover them but the misc partition is missing ,so the phone have no back and home button , no notification bar no sound and no wifi, if i update to any rom it will stuck to boot logo ( finaly updated to v29b170 but work only if i don't flash boot)
I think the problem is comming from this partition "misc" it's a configuration partition i think
So if any one can share this partition it will be helpfull
No mater from l29 l09 or al10 i want give it a try
Thank you

any one can help pls , im not sure it will work but i want give a try
thank you

You can not solve this problem by using mic file.ok
You can flash the complete stock .

Hey man, I got a problem just like you and this is the way I fixed it.
Download the Huawei update extractor:
https://forum.xda-developers.com/showthread.php?t=2433454
And use this to open your Update.app you already downloaded.
Extract the 'boot.img' and the 'system.img'.
Now you need fastboot, follow this tutorial:
https://www.xda-developers.com/xda-...tall-adb-and-fastboot-system-wide-in-windows/
Now open terminal/cmd/powershell and open the folder the boot.img and system.img you extracted are in.
Connect your phone in fastboot and run the following commands:
fastboot flash system [Extracted_System.Img]
fastboot flash boot [Extracted_Boot.img]
fastboot reboot
This resolved the issue for me, I hope also for you!

How did he brick it? What was he specifically doing (nougat update etc.)? Do you get the same error when you try and flash a boot image, stock recovery or other partitions?
Can you install twrp? If so, try wiping the system & boot partitions in twrp, then try flashing boot & system again in fastboot. If he'd updated to nougat, then you'll need to try and flash the rollback package first then dload a Marshmallow rom and go from there

I would suggest using this tool:
https://forum.xda-developers.com/p9/development/huawei-p9-eva-l09-eva-l19-eva-l29-tool-t3591358
to install this tool to unlock bootloader and install twrp.
After unlocking your bootloader everything on your phone is gone though.
Then in twrp you can try to repair your your partitians by going to wipe->advanced wipe->repair or change...
And thereafter continue with the steps is provided earlier or install a new rom, this is up to you.
I hope it fixes it for you.

I'l try that and update.

i have twrp. repaired the partitions. did the flast via fast boot using the above method
"Now open terminal/cmd/powershell and open the folder the boot.img and system.img you extracted are in.
Connect your phone in fastboot and run the following commands:
fastboot flash system [Extracted_System.Img]
fastboot flash boot [Extracted_Boot.img]
fastboot reboot"
and still the same. It flashes the files fine. but at boot i get a black screen.
I think im using the wrong files. Can anyone please share the link for a full stock rom nougat , or a roll back from nougat to mm (i flashed this VNS-L21C185B360 latest)

or maybe i need to do write the oeminfo or something. Read it somewhere. not clear on what it is

solved my problem.
Putting the puzzle back again:
I think the genius removed the oeminfo along with everything else he could see in the twrp wipe menu.
I tried to put multiple firmwares on the device nougat ( as he updated) but the boot still showed blank.
As soon as i flashed the oeminfo --> then MM firmware, the device booted up.
Thank you so much everyone for your help. Really appreciate it :good::good::good::good::good::good:

Excellent! :good::good:
And I'm sure your friend is glad to have a working phone again!
Explains why dload wouldn't work as well. As far as I'm aware the update.app checks oeminfo to make sure the firmware is compatible. Hence if you want to debrand a phone to C432, you have to flash a C432 oeminfo before the C432 update.app will flash successfully. No oeminfo=no compatibility for anything!!!

finished. total time: 15.142s
Update: To get into fastboot is very important that smartphone is connected via USB to PC, then Power-button and VolumeDown together till Phone gets into fastboot.
from there flash TWRP, and reboot to recovery, after that install full Update (Files and guideline is here in first post part 3 and 4 https://forum.xda-developers.com/p9/development/rom-huawei-p9-magic-rainbow-t3601064).

solved my problem.
Putting the puzzle back again:
I think the genius removed the oeminfo along with everything else he could see in the twrp wipe menu.
I tried to put multiple firmwares on the device nougat ( as he updated) but the boot still showed blank.
As soon as i flashed the oeminfo --> then MM firmware, the device booted up.
Thank you so much everyone for your help. Really appreciate it :good::good::good::good::good::good:

help! no ROM after system wipe on TWRP

hello everybody... PANIC!!
Have the CRR L 009 version; made the following steps on the C900 B371 FW:
- Unlocked the bootloader with the code using ADB
- Flashed the TWRP custom recovery
- Wiped cache, system, data, dalvik
Now I'm stuck with NO ROM and i don't know how to flash anything! I made these steps because I knew how to do this with my old LG D855, but now I can't go on...
Please help me!
PS: my objective was to change customer to C432 and obtain more recent updates...

easiest way is to flash the boot.img and recovery.img of a full firmware for the crr-l09..
i think the last full firmware is the b36x with c432..
after flashing (through adb) the img you can install the full firmware by 3button method (search around the forum, it is described very often how to do this)..
good luck

Download the last version B390, use huawei extractor and extract system, boot, cust.....then flash them with ADB in that order. That's it

nooooo, flash them with ADB in your PC....don't use TWRP....
use the same method that you use to flash TWRP in your phone but after you extract system, boot and cust from the "update.app" you have to flash them with "fastboot flash system system.img...and boot boot.img and cust cust.img"

aaah ok!!!
but let's return to the main question: is it worth the effort to do all these things for the B390?
Are we going to get some update? I think we've been unlucky with these phone... it seems like it has been forgotten by huawei

maybe we have, but this is for rebirth your phone xD
