Hi, if you don't know what is fastboot maybe you can approach it the easy way.

Download and install this for the correct drivers : http://consumer.huawei.com/minisite/HiSuite_en/index.html

Download and extract to a folder this : https://mega.nz/#!B4tATA5D!-TseQ9A-TPEQhzNQRXsT_cV2i4T7qYYLadceW0fM8k0

Put your phone in fastboot mode : Turn it off. Connect it to your pc . Long press vol - and power until it boots in fastboot mode (white screen with a green android and other stuff). If you want you can boot in fastboot from TWRP recovery : restart -> bootloader.

Copy your extracted SYSTEM.IMG in the root path of the tool (we can assume its name is system.img).

Now launch the tool and press 000 and enter.

If you have done all right now you can give this : fastboot flash system system.img

Wait about 3 minutes. Perform a cache and dalvik cache wipe. Boot your phone.
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Hi,

I am using the standard P9, and getting the Boot Loop also.

I attempted your instructions, and appeared to work - I got the first EMUI initialization screen - and now its gone back to how it was.

Any suggestions?
[Huawei P9 Lite Questions & Answers] Zeph1990:
I think it should work on every phone assuming you are using the right firmware. Do you use the right firmware for the huawei P9 ?? (needless to say it's not the version i posted)).

So if you flashed the right firmware (and i'm pretty sure of this) my advice is to perform a full wipe : Cache, dalvik and data.

If you are still facing the same error consider flashing other frimware parts like boot.img ecc.
[Huawei P9 Lite Questions & Answers] SpongeN0b:
I believe so - I am pretty clueless with this stuff.

By firmware, do you mean the stock version? Because I used P9-EVAL09-EVA-B136. Don't suppose you would know the right firmware I require?
[Huawei P9 Lite Questions & Answers] Zeph1990:
I think it's the right version. I am a p9lite user so i don't know specifically the right version of the firmware but i think it's ok. Do you tried a full wipe?
[Huawei P9 Lite Questions & Answers] SpongeN0b:
How can I perform a full wipe? Thanks for replying by the way
[Huawei P9 Lite Questions & Answers] Zeph1990:
So, do you have unlocked bootloader and custom recovery (TWRP) ?
[Huawei P9 Lite Questions & Answers] SpongeN0b:
I do yes
[Huawei P9 Lite Questions & Answers] Zeph1990:
So, go in twrp recovery (turn off phone, long press vol up and power for at least 3 seconds). When you are in you will see 'WIPE' press it then do the swipe to Factory Reset. You will lost your installed apps and the relative settings but you will not lost your personal stuff such photo,music documents ecc. Let me know if you perform it and if it works =)
[Huawei P9 Lite Questions & Answers] SpongeN0b:
It appears that TWRP no longer appears. I get thr EMUI options to wipe data/factory reset. But once I do this I just get a red exclamation mark.

Does the phone need to be plugged in via USB?
[Huawei P9 Lite Questions & Answers] Zeph1990:
No you don't need to plug your phone.

Donwload this https://dl.twrp.me/eva/twrp-3.0.2-0-eva.img.html . Rename it to recovery.img .

Download and extract to a folder this : https://mega.nz/#!B4tATA5D!-TseQ9A-T...YYLadceW0fM8k0

Put your phone in fastboot mode : Turn it off. Connect it to your pc . Long press vol - and power until it boots in fastboot mode (white screen with a green android and other stuff).

Copy your extracted recovery.img in tool's root direcotry.

Now launch the tool and press 000 and enter.

If you have done all right now you can give this : fastboot flash recovery recovery.img

Now you have flashed twrp and you can perform a full wipe like i said
[Huawei P9 Lite Questions & Answers] SpongeN0b:
I need a decryption key for the mega.nz file
[Huawei P9 Lite Questions & Answers] Zeph1990:
Sorry, try this link https://mega.nz/#!B4tATA5D!-TseQ9A-TPEQhzNQRXsT_cV2i4T7qYYLadceW0fM8k0
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Thanks - downloaded both of those.

So I rename the file to recovery.img, then drag that into the SRKToolHuawei folder - then launch the .exe within that folder?
[Huawei P9 Lite Questions & Answers] Zeph1990:
Yes =) But firt of all you need to put your phone in fastboot
[Huawei P9 Lite Questions & Answers] SpongeN0b:
It says:

"C:\Users\Tom\Desktop\SRKToolHuawei-STABLE-V1.3-20160619>fastboot flash recovery recovery.img

error: cannot load 'recovery.img'"
[Huawei P9 Lite Questions & Answers] Zeph1990:
Ok, sorry for the question but just to be clear, the filename must be recovery the .img is the extension. So looking it in your folder you read only 'recovery'. Right?? :D
[Huawei P9 Lite Questions & Answers] SpongeN0b:
My fault! I was confused :)

TWRP is back! You know your stuff. So I have gone back into and selected WIPE, then swiped to perform Factory Reset - I then get this on my screen (bold text is in red):

Failed to mount '/data' (Invalid argument)

Unable to recreate /data/media folder.

Updating partition details...

Failed to mount '/data' (Invalid argument)

...done

Unable to mount storage

Unable to mount /data/media/TWRP/.twrps

MTP Enabled

Formatting Cache using make_ext4fs...

Updating partition details...

Failed to mount '/data' (Invalid argument)

...done

I then selected the REBOOT option, and the phone is stuck on the "Your device has been unlocked and can't be trusted." screen.
[Huawei P9 Lite Questions & Answers] Zeph1990:
You have the data partition corrupted. Can't say why. First time i saw something like that. Go Back to huawei update extractor select UPDATE.APP then extract userdata.img.

Put it in the root folder of SRK.. then flash it. (like for the recovery.img file) The command is : fastboot flash userdata userdata.img. Then go back to twrp and try a full wipe
[Huawei P9 Lite Questions & Answers] SpongeN0b:
I will try this in the morning - have an extra early morning tomorrow. Thanks for all your help and i will let you know how I get on :)
[Huawei P9 Lite Questions & Answers] Zeph1990:
Yeah man it's a bit late . I have push notification on this thread so if you need it i will try to help you =)
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Sorry one last question lol. The UPDATE.APP is the stock firmware right?
[Huawei P9 Lite Questions & Answers] Zeph1990:
Yes man the stock firmware =)
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Hey :)

So I tried what you advised last night - and unfortunately did not work.

I get this error again:

Failed to mount '/data' (Invalid argument)

Unable to recreate /data/media folder.

Updating partition details...

Failed to mount '/data' (Invalid argument)

...done

Unable to mount storage

Failed to mount '/data' (Invalid argument)

I googled the above error - and when I went into advanced options for WIPE and checked Repair DATA, it says:

Free: 0MB

Removable: No

Could this be missing?
[Huawei P9 Lite Questions & Answers] Zeph1990:
It's very strange. Let's try to change recovery. Download this https://www.androidfilehost.com/?fid=24572369242688913. Extract it find recovery folder. Now search for twrp image for p9 and copy it to the root folder and rename it ro recovery.img. Flash it like you did yesterday and try to do wipes. Let me know
[Huawei P9 Lite Questions & Answers] SpongeN0b:
By root folder - you mean the folder that the SRKToolHuawei-STABLE-V1.5-20160717.exe is stored in?
[Huawei P9 Lite Questions & Answers] Zeph1990:
Yes
[Huawei P9 Lite Questions & Answers] SpongeN0b:
The wipe worked - but it still just sits on the boot screen (not Huawei logo, the "Your device has been unlocked and cant be trusted - your device is booting now..."
[Huawei P9 Lite Questions & Answers] Zeph1990:
So the recovery it's ok now. Sorry for that. So last try,

Try to flash boot.img. Extract it with huawei update extractor and copy in root folder of the tool then you can flash it with fastboot flash boot boot.img. You can reflash the system.img too for a clean installation. Then enter in recovery and full wipe. Cross your finger and boot
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Should I use the first SRKTool you supplied, or the most recent?
[Huawei P9 Lite Questions & Answers] Zeph1990:
It's the same =)
[Huawei P9 Lite Questions & Answers] SpongeN0b:
OH MY GOD - ITS BOOTED!!!!!

Thank you so much!!! I love you hahaha.
[Huawei P9 Lite Questions & Answers] Zeph1990:
So happy =)
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Thank you so much.

One thing ive noticed so far is that Themes arent working?
[Huawei P9 Lite Questions & Answers] Zeph1990:
You know i can't answer to you on this i don't know very well p9 but hey it's working! :D
[Huawei P9 Lite Questions & Answers] SpongeN0b:
Haha its ok - thanks again!!
[Huawei P9 Lite Questions & Answers] darthkir:
Hi. Ive followed precisely everything on my P9. Tried the stock recovery from the UPDATE.zip, twrp, stock and twrp from the SRK tool. I didnt even managed to get to TWRP boot, everytime it still gave me the eRecovery without the option to wipe anything.

Everything looked OK during flash but I still get this when booted:

"Your device has been unlocked and cant be trusted - your device is booting now..."

Is there anyway I can upload the entire "dload" folder so I can flash using the vol up + vol down + power method? The one i have inside the phone now contains the UPDATE.zip for the Beta 7.0.

Please help.

p/s: I got this issue after trying the Beta 7.0
[Huawei P9 Lite Questions & Answers] Zeph1990:
Hi, yes i think you need to flash the entire update.app. The problem is about your unlocked bootloader. The vol - vol + procedure does not work when the bootloader is unlocked. So i think you need to extract all the parts and flash them one at time.
[Huawei P9 Lite Questions & Answers] El Brillantinas:
Sir, you saved the life of my Huawei P9. I did some bad stuff in twrp causing the "encryption unsuccesful" error, but I follow your advices and now I could start it. A million thanks to you.
[Huawei P9 Lite Questions & Answers] Zeph1990:
Great!
[Huawei P9 Lite Questions & Answers] zukriaksah:
Happen to me too, I still managed to boot up my phone, but without default themes and magazine unlock wallpapers. Ended up with nougat again, yes it's true, happen because of the data partition corrupted, while trying to change the ro.display.id... So are you sure this method, by flashing userdata.img tru' adb can fix the problem?

Hello.

Same problem here....

When I connect the phone (online), adb say phone is detect, when I reboot to bootloader to flash something (twrp for example) adb not find my device. I think the problem is here.

It's happen after unlock bootloader and root, after that I can't connect to google account. I flash oeminfo and another file, now I can connect to google, but I can't install twrp or something else.

I can't install anything with fastboot or srktool

Can someone help me ?

Thanks
[Huawei P9 Lite Questions & Answers] HelLViS69:
Hi, my phone bricked after a ROM integration of Google Play Services via Titanium Backup.. :confused:

I followed what you said for downloading/extracting/installing stock rom. I forgot to wipe cache and dalvik/art cache and phone booted, giving me time to see:

1. in Settings now there is a new entry which says the phone is American

2. in Settings, Status entry immediately crash

The real big problem is that I can't unlock sim card but the number of attempts are always 3 :confused:

So I rebooted in TWRP and wiped all caches, rebooted phone and the problem remained, can't unlock the sim and I can't move away from sim unlock screen :eek:

Any clue?
[Huawei P9 Lite Questions & Answers] Somel:
Hi guys,

A little of a strange one. A friend of mine just soft bricked the phone and he asked my help. However this one I need your assistance too.

- Apparently phone is black dead.

- when connected to pc the device appears as fastboot devices

- device does not show up through adb

- bootloader is unlocked.

- was able, apparently, to reload boot, recovery and system image through fastboot

- some commands in fastboot show as remote not allowed.

- fastboot reboot either simple for recovery or to bootloader appears message ok but phone never reboots

- HW buttons do not allow me to switch off or restart the phone. Phone is basically always on.

Any further suggestions?

I'm going nuts !!!!!

Hey there, I also got bootloop my p9 lite in nougat. Can you make a guide on how you fix yours? Or do you know a way to go back to MM? I really appreciate it if you could help. I badly need a help now. :crying::crying::(

I have P9 lite bootloop in nougat.

Thanks for any help.
[Huawei P9 Lite Questions & Answers] Zeph1990:
Hi there. I didn't upgrade to nougat because i need the phone working but i have made some research for you guys.. and there is a nice tutorial on htcmania.com.

So. First of all you need an unlocked bootloader. Same guide as always.

Now, let's come back to MM!

https://drive.google.com/file/d/0B_2rmU9Nol-qSE5JNmdsSHpidXM/view?usp=sharing

I suggest to download only :

1 : C432oEMINFO-DUALSIM-P9LITE.ZIP

2 : twrp.img (under TWRP nougat , data )

Now :

1 : flash twrp using: fastboot flash recovery twrp.img (as always you can search tons of tuts here on xda)

2 : usign twrp, flash C432oEMINFO-DUALSIM-P9LITE.ZIP file.

If everything it's ok, now you can flash the MM firmware using the 3 buttons menu. So , download the B161 Firmware (FULL!!) extract UPDATE.APP and place it in dload folder.(create it if it doen't exists). Then start phone while pressing vol + and vol - .

This procedure will erase all your data!

The original htcmania.com guide is here : http://www.htcmania.com/showthread.php?t=1261335

But i think you can figure out using my little guide =)

Keep me updated !

[Huawei P9 Lite Questions & Answers] Jagiel88:
Extract update.app (Huawei Update Extractor), go to fastboot&rescue mode, flash recovery partition (recovery.img) so you will have stock recovery. You may also flash TWRP recovery image (find it on Meticulus project site) if you want. If you want to downgrade from Nougat to Marshmallow, find some tutorial for it, because I guess only Nougat ROM will install now for you from dload folder.
