GUIDE: Obtain your bootloader unlock code from Huawei

Note: This applies to the Chinese version. It might also apply to the international version, but since I don't have an international Mate 9, I can't be sure. I just got my unlock code from Huawei the very hard way, so hopefully this guide will make it a little easier for everyone.
UPDATE: Because Chinese text is not displaying correctly in XDA, please see here for the tutorial:
http://pastebin.com/RYSvQq21
Thanks button presses are always welcome. Donations are even more welcome. I've spent tons of time working on this phone! PM me if you want to send a few bucks my way.
AGAIN, THIS APPLIES TO THE CHINESE VERSION (MHA-AL00) APPARENTLY IF YOU HAVE THE MHA-L29 YOU WILL BE MORE SUCCESSFUL CONTACTING HUAWEI EUROPE

Just running through the process now - Thank you for all your help, you are a star.

I sent an email to get my code to unlock the bootloader, now I'm waiting. Thanks to you

Hello,
Does unlock the bootloader with a Huawei official code cancel the warranty of the phone?

Yes, if the phone breaks due to something you flashed, etc.

So, has anyone gotten a response?

Don't give up guys. Just keep emailing Huawei twice a day until they relent. :silly:

No harm in trying.

So, please, I hope to hear more reports. I REALLY hope that someone with MHA-L29C900 or MHA-L29C432 can get their codes soon, and help with the oeminfo collection.

@duraaraa
can you please update the title of the thread to mention this is for the L00 as some people sometimes don't read well the first post lol.
As for the L29 it's much faster apparently, we just need to call Huawei in the country where you bought the phone, then they will send it to you in 3-4 days.
I have a friend who asked for it yesterday, an got it today. I will be calling the today again just in case to be sure to get it.
Thanks !

I sent him your message, he is also a dev. His name is @Tkkg1994 (superman rom, kernel etc.. on S7 and Hydra Rom & kernel on N7) you can also contact him on telegram with @Tkkg1994. Most probably he is under the radar trying to work on it as we speak.

Rollback to mm from NRD90m test-keys HELP

How i can downgrade NRD90m test-keys to L21C432b160 mm with a rollback package ? i tried to put in dload folder but doesent work, i have no root,bootloader is lock(because huawei refuse to give the unlock key), no custom recovery. i want to downgrade because a lot of app is missing , and i want official when they relese it. Thanks and sorry for bad english!

was this updated through official methods?
i have the nrd90-test keys build and i have not managed to find a working image for the DLOAD folder. im also not sure if you can downgrade that easy there is a spanish forum that is oftne linked here with a downgrade guide but you 100% need unlocked bootloader to do that.

No i updated trough Charles app with fake ip adress. I tried to unlock bootloader but Huawei doesent want to give me unlock key because warranty,they sended me a mail.

MANY, MANY people warn about not using that method (even me) because it doesn't let you update correctly, why d'you do that? Now without an unlocked bootloader you can't even go back. Can't do anything, actually. Because to go back to MM you need it unlocked. Any other method doesn't work. Just try to obtain the bootloader code, in the meantime you can't do anything but wait. Maybe next time read other people's experiences before trying to mod your device?

I Think You were using wrong update.app . Tell me your modle number & region . I will give update.app. You can easily rollback with it

Hi, I'm currently running in android 7.0, I done the unofficial update and as it happened to everyone I don't have all the apps, I have unlocked. Bootloader, I live in UK and my model number is VNS-L31, if you give the right "update.app" file and I put it In a folder called dloader that I will make then press [+vol]+[-vol]+[power] it will downgrade to the normal update and it will be the same like when I bought it?

Try dc phoenix. To load a mm update.app. Should work even with locked boot loader or if you brick the phone. I had a similar thing happen with an it's update, I think its because I had root and redo installed.

i ended up sending the device to huawei vip service, they replaced the motherboard. i was kind of surprised, i had expected them to just reflash stock firmware but no.

Frendly reminder to unlock your bootloader

If you intend to do basically anything with this phone I highly recommend unlocking the bootloader and leaving it in that state always. Especially do this before accepting any kind of beta ota because you might not be able to roll back without bootloader unlock. Do not for any reason try locking your bootloader again unless a rom you are using specifically says to do so like Copperhead or you may end up semi or hardbricking your device. Having and leaving your bootloader unlocked also makes it possible to recover from almost every single possible problem that can arise with the device on a firmware/os level.

Yes,
Recent Non Beta OTA Update also Ruined the Phone. Since the Device was Locked it turned into a Useless Brick Now.
So its Strongly advisable to keep the Developer Mode on with USB Debugging ON and Allow Boot-loader Unlock Option ON at-least.

This is mostly the problem I'm referring to as I've now seen like 5 people who are stuck with a broken ota or are stuck on beta with no way off

Doesn't matter where you are, but there is a post or two on here talking about a guy who can unlock it using remote access and installing flexihub on your machine. If you wanna try it make a windows VM real quick and wipe ur phone after you back everything up that you need

A misparsed or improperly fetched OTA can semi-brick a phone yes. It can also happen when the manufacturer or carrier push a broken update. Both scenarios have happened many times with lg and Samsung phones for example

P9 lite stock rom

Hi, I have a p9 lite VNS-L31 european version. It has nasty vodafone branding that I want to get rid of. I have tried the metods suggested in other threads here where you copy update.app into a folder called dload on an sd card and restart the phone holding down the two buttons on the side, but all I get is it fail repeatedly at 5%.
I have read around threads but I am none the wiser. Any advice would be appreciated before I throw this thing out of the window because this crappy vodafone rom is going to die one way or another.
Thanks

im on same situation.. the only thing i can flash is c432b160 from huawei site and i can flash only via fastboot
if i flash with same method the new rom 5.0 it will hang on boot up

Sorry to hear Sergio. It looks like this has been done deliberately which makes me super mad. I have tried ADB and fastboot and it still will not let me do it.
Would rooting help to get rid of this crap on our phones?

Hey guys i think you are saying two different things...
About @ba_baracuss i suggest you to rebrand your firmware from your ( C02/vodafone ) to C432 ( european general ) firmware.
To do this you need your bootloader unlocking number first....
If you are on a marshmallow firmware use K1ll3r8e toolkit
If are on nougat firmware you can use HWOTA like explained in this thread.
 @sergio_f i think you already tried everything, really don't know how you will get rid of this.
Maybe you could try to update first to B170 using DLOAD method then see if OTA offer you NOUGAT updates...
All the best guys

Sorry dude i had a false memory..
I checked for it too and it doesn't exist... I was asking if you had even B160 firmware.
Is your device a dual sim one ? Have you rooted and / or flashed custom recovery ?
If not maybe could be helpful make a rollback to your first firmware ( ex. B150 ) or reflash B160 again, but i'm not really sure....
Brick is behind the corner, proceed with caution..

Thanks for your reply @Dadditz. Unfortunately I can't solve it yet.
You said I need bootloader unlocking number first - I do not have it. I have tried that before, going to huawei site and putting in various phone info. At the end it gives a dead webpage, with no unlocking number.
I am on nougat and so followed your link and have downloaded the HWOTA as directed, copied to memory card, then when I enter recovery by holding down the buttons on the side, it does a factory recovery and I still have the vodafone branding.
I don't get what he does in the youtube video at all. I just get EMUI recovery and back to vodafone.
Where am I going wrong? Is it because I need the unlocking number? If so how can I get it when the huawei page doesn't work?
Thanks for your help so far, it is appreciated.

Hi,
unfortunately you cannot rebrand without unlocking you bootloader first and flashing a custom recovery...
This is very well explained on the threads i linked you my friend....
If sergio_f cannot help you ( grab the unlocking bootloader number ), maybe with DC-Phoenix, paying some euro/dollar/yen you could do this...
Do some search about...
P.S.: read carefully the guides when you find one... ( at least twice )
@sergio_f
really don't know dude, if OTA stock doesn't work, try with HISUITE, i don't know if dc-phoenix could help.
Under your responsability you could try to follow some guides about rollback or rebrand ( to your actual CUST C432 ),
reflashing then your actual firmware....
I know it's a s***ty standby, but only you can choose.

Thanks for the reply. I have done lots of searching and downloading for days to the point where I will soon smash the phone with a hammer.
I have tried dc unlocker and it says this:

I don't know what that means. Is it because you have to pay to use it and get a username or something?

Hello,
yes like i told this is a paid program. I never used it but I think it's not hard to get work done...
The site provides tutorials on how to read the bootloader code... here
and how to unlock it... here, and a lot of tutorials are present here on XDA too, just search...
Delete ( eventually ) registered firgerprints, enable USB-DEBUGGING and OEM-UNLOCK to proceed...
Usually somethings missed so it's very important to read the guides at least a couple of times.
Best regards

Thanks Dadditz. I have now got a bootloader code, but cannot enter it.
I have tried the guide on the dc unlocker link and also found one here: https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701 using SRK tool, but neither can detect the phone.
The droidth SRK tool sticks at 'waiting for device'.
I have enabled USB debugging and OEM unlock, but it still doesn't work.
I will keep trying but if anyone has any suggestions it would be appreciated.
Oh, and I have tried asking on dc-unlocker forum but my post does not appear. I am guessing they block new members posts until admins enable it or some bull****.

Flashing OOS on Chinese OP6T (A6010) that comes with H2OS

I am getting a Chinese OP6T that comes with H2OS in 2 weeks time. Any easy way (guide) to flash stock OOS to this Chinese phone A6010? Thanks in advance.

just unlock the bootloader and sideload the oos.zip (full) in stock recovery then flash it from there. you could also do fastboot method. works on my oneplus device since the 3/3T days.

Have you done it for oneplus 6T yourself? I was wondering whether the A/B partitions in OP6T will have a different approach to flash...
Thank you.

according to my friend chinese oneplus 6
you only need a full flash zip of oos and just local update from updater in the phone
no need to unlock bootloader
PS. and no need to factory reset too, but i still recommend to reset it

I am from China, and use Chinese OP6T (A6010) that comes with H2OS
just like fangchunxi1999 says, put full OOS zip on 6t sdcard, local update from updater in the phone setting
after finish, do a factory reset, OOS now!

Interestingly enough I just bought a 6t in China and I have been thinking about this.
- Question for you. Will you still be in China? If not, or you are planning a vacation somewhere, OnePlus support will actually help you flash OOS on your device. This only works outside of China though (even if you have a VPN).
- For others: what is the big difference between H2OS and OOS? I considered flashing, but I have a trip outside of China in a week so I was thinking I can just wait until then and let OnePlus do the flash for me. For now though, I have installed all the apps I want including Google apps and a VPN. Is there any real reason I would want to flash to OOS instead of just leaving it as H2OS? Thanks for any answers.

Interestingly enough I just bought a 6t in China and I have been thinking about this.

No. I am in Malaysia. I ask someone who happen to be there to bring it back for me. Dont think there is a oneplus support Centre here.

Thank you so much for sharing your experience! I will do the same when I get hold of my phone. I asked someone to hand carry for me.
By the way, do you root your phone too?

Yes, root just after OOS first boot.

This isn't at a support center. I just asked used OnePlus support online and they can do it for you through a PC with Windows installed.

according to my friend chinese oneplus 6
you only need a full flash zip of oos and just local update from updater in the phone
no need to unlock bootloader
PS. and no need to factory reset too, but i still recommend to reset it

Just got Device is corrupted, dont know how to restore it back. Someone said I could use MMSDownloadTool but there was not a version for HydrogenOS. I wonder I could use this from International MMSDownloadTool but I'm so afraid I would brick my Chinese variant device.

Well here's a question. If I wanted to flash h2os onto my international unlocked op6t could I do the same method just reversed?

In all honesty, you can either:
Unlock the bootloader back and just use the device as is or sideload the OOS.zip or you can try the global tool and hope for the best, since unless you unlock, the device is unusable anyways, if someone can get the Chinese variants tool it would be a Chinese user, others can’t request it..you’re better off contacting OP via chat and push for an OS reflash until they oblige and make an appointment with a tech to remote flash for you.

Well I would guess they work vice verse, worse case it doesn’t work, you can always use the msm tool to recover.

Guys i want to flash OOS on my 6T A6010(chinese), but i can't do it from updater neither from recovery... How i can flash oxygen? Some guys adviced me to try the download tool but i have to unlock bootloader. do you think is it safe to do that? Hope in your help...

Just follow the method mentioned in post 4 and 5. I tried it and it worked. No need to unlock bootloader if you dont want.

i found a solution, thank you anyway

I have tried de system update method, but I receive the message "The version of your selected package is lower than that of the current system. to avoid booting up failure, downgrading is not allowed"
Help!

I installed the hydrogen os a few days ago, and it was a nightmare.the boot animation was neat. And the oppo play store has more recent updates than play..

after switching to OOS, will one still get OTAs?

Where can I get the h2os full zip?
