Need help regarding bootloader unlock - Huawei P9 Questions & Answers

Is it necessary to apply for unlock codes at huawei's website to unlock the bootloader if I can see / access / toggle "OEM UNLCOCK" in developer options? The phone ( Huawei P9 ) is my mother's and is planning on handing it down to me.

Better be quick. Huawei is shutting down the official bootloader unlock method. Go to https://emui.huawei.com/en/ and log in. For "old" models huawei gives you 60 days to get an unlock-code. After this time there's DCUnlocker to unlock.

OEM Unlock is just a prerequisite, with that you will have FRP unlocked but you still need unique code for your device to unlock Bootloader
Better be quick... See that other response
PS: You need to open that Huawei portal from PC or as Desktop site to have Bootloader unlock code options

Can we still unlock the bootloader on the Honor 9 lite?

Hey all,
So I've heard that Huawei has stopped giving out unlock codes? I tried to go to their website to apply for it (giving my IMEI etc) and instead of giving me a code it just says 'please contact Huawei for questions'
I'm trying to set up project treble with it if I can figure it out.
Thanks!
You can with dc unlocker. You Just need to pay 5 euros and they Will unlock boatloader
I got my code on 08/06/2018
In the morning at 7:05 AM IST on 08/06/2018 i applied for my bootloader unlock code and i got it easily. BTW did you cross check other pre-selected options? Like 1st one asking EMUI version? Maybe that's the reason of you not getting unlock code.
Try again or Use the mailing method(I don't know much about but you have to mail the support to obtain the unlocking code and it might take upto 2-3 days)
Just got my code for bootloader unlock directly from Huawei no issues, although i will not be using straight away i have kept it in a safe place.

I tried through their portal, and via email. This was their response:
We do apologize for the inconvenience you are experiencing, however, it is our duty to inform you that Huawei Canada does not provide codes to unlock the bootloader, root the device or provides any tool/code to modify the phone internally. We kindly inform you that this action can potentially "brick" the phone or in other words, renders the phone completely unusable and voids the warranty service and device support. We have no control over how unlocking the bootloader or rooting the phone, will affect your device.
We understand that you might be able to start the request to get the bootloader unlock code from our EMUI website, regrettably, your device does not qualify to receive this code, since the Huawei Canada warranty policy limits us to do not provide this code in order to prevent future inconveniences to our consumers.
This bootloader unlocks code, it is just limited to be available for certain specific regions.
We are aware that you can find unofficial information over the internet, about how to root or unlock your phone and due to our Security and Privacy Policies, we cannot provide you these codes or tools, for that reason, we cannot assist you in that matter.
We highly recommend you refrain from taking these actions on your device.

I read the instructions for unlock of Huawei mobile, it requires you erase the Huawei id.
How does that affect warranty?
Can you reapply the old id if necessary?

No, you can't. DC-Unlocker neither autodetects the phone nor is it in the manual selection list. Also https://www.dc-unlocker.com/supported_models_1/huawei_phones says no bootloader unlocking service for said phone.
On the other hand Huawei support gave me this reply (translated by me) :
Hello [censored],
sadly the bootloader unlock code service has been terminated completely. I'm really sorry but I can't help you.
Best wishes,

Not true !

Thanks for this, it appears to be the only bootloader unlock method currently available. Have you actually done this yourself? Can you (or anyone else) confirm that it works?
By the "instructions", I assume you mean the tutorial at http://hcu-client.com/read-bootloader-code-huawei-phone/. They seem clear, but they don't tell you how to actually use the code to unlock the bootloader! Can someone please point me to instructions how to do that? Thank you.

Yep, I mean the tutorial.
I have used this method a good few times, all successfully .
Dc-Unlocker/HCU allows direct unlock on a lot of models and gives the unlock code on others.
To use this code, put phone in "fastboot" mode and issue the command :-
fastboot oem unlock code
Phone should factory re-set (erasing all user data) with an unlocked bootloader.

I can confirm. There's just one thing to note: Deinstall the adb drivers from Microsoft and use the ones shipped with HiSuite. Else there will be no virtual COM port and as a result the tool won't find the phone. [EDIT]And don't try to use the tool in a VM. Sadly it refuses to work there.[/EDIT]
Can someone please point me to instructions how to do that?

1) Enable Settings > Developer Options > Enable OEM Unlock
2) Enable Settings > Developer Options > USB Debugging
3) Turn off phone
4) Press volume down key while connecting the phone to USB to boot the phone into fastboot
5) Execute "fastboot oem unlock <unlocking code>" on the PC the phone is connected to (install adb and fastboot first)
P.S. Many thanks to @Sparkrite for pointing us in the right direction!

Great, thank you! It's reassuring to know it works reliably. And I'm glad the unlocking process itself is so simple; I remember now having used the same method on another phone some time ago.

Thank you so much. With this method I successfully unlocked the bootloader of my Huawei Honor 9 Lite. No problems, just one oddity – the HCU software warns you that reading the bootloader unlock code will wipe your phone, and you have to acknowledge that to continue. This, of course, is not the case: it is using the code to unlock the bootloader that causes the phone to do a low-level reset. Presumably a mistake in the wording.

I used HCU to read the bootloader unlock code before I saw your message, and so had not uninstalled the Microsoft ADB drivers. I had already installed HiSuite. It still worked for me, so presumably it is not necessary to uninstall the Microsoft ADB drivers unless HCU doesn't recognize the phone.

Any news?
Many thanks to those who contributed to this thread. I had no trouble unlocking the bootloader of my device using HCU after purchasing credit from DC-unlocker. At only 4 euros it was worth the money. The posted instructions were clear. Once HCU provided the code all I had to do was send it to the phone using fastboot..

Bootloader re-locked after OTA update

Hey, for a reasons I needed to do ota update (reflashed stock recovery[extracted from matching update] before doing so), now when im trying to reinstall TWRP i've noticed that my bootloader re-locked on its own.
Was this supposed to happen? iirc people keep telling you that you can't relock bootloader without it's backup from locked state.
It's quite annoying that it happen since I did pay for unlock via DC unlocker and now huawei stopped distributing unlock codes so I'll probably need to pay DC again.
Cheers!
edit: DC unlocker did not even allow me to Unlock bootloader, only thing i saw was Lock bootloader, but there was option to "Read bootloader code" (no credits needed) and I managed to unlock bootloader again using fastboot and this code

This is a flag in OTA update, it may be present or not (now seems to be always enforced, new Huawei policy) that OTA locks Bootloader
You cannot disable this flag in OTA package
Bootloader is not relocked but really locked (better for those who go to service under warranty)
Bootloader code is unique for your device.
No matter did you obtain it from Huawei or DC, you have TO KEEP it, you don't need to pay, read or ask again, just use the same bootloader code for the same phone for the lifetime of your phone

thanks for the answer, didnt know about flag nor that bootloader unlock code can be used multiple times(and that its paired with HW)
nevertheless, as I said in my edit I managed to get my unlock code for free with dc unlocker

that's what I suspect, but sadly can't confirm or deny. I think I didn't even see the code itself when I used it for the first time due to the fact that unlock process was automatized within DC unlocker's client app, so all I had to do was to prepare the phone and press Unlock Bootloader within the client

I used DC client once (4 Euros), I obtained the code (saved it for future) and used in Fastboot to unlock Bootloader just like previously for the other Huawei phone whose code I obtained for free from Huawei (before they closed this service)

HELP. Issues after Rebranding

Hi all, I need your help please.
I've recently rebranded my CLT-L04 P20Pro to CLT-L29 emui 9 using Funkyhuawei.
After the rebranding the bootloader is still unlocked but FRP is locked
ADB and fastboot commands will not work. I can use fastboot to check bootloader status etc etc but not push commands to write recovery or whatever.
Does anyone have a solution to maybe go back to CLT-L04 ? Thanks
Enable OEM unlock in dev options ? (to unlock FRP)
Or you can't log at all on the phone ?

If you don't have Bootloader unlocked just go to Settings /System/ Developer options and switch off OEM Unlock (=FRP Unlock)
Btw, there is no need for panic because of unlocked FRP (and/or because of its warning while booting

You didn't state here but from your another post (you installed RR), you unlocked Bootloader and therefore obviously you had to unlock OEM/FRP
If you don't like unlocked FRP, then you first go back to stock Nougat, re-lock Bootloader and forget about rooting, installing custom ROMs, etc - for all that you must have unlocked Bootloader AND unlocked FRP
i need do UNLOCK FRP but on OREO i cant find setting UNLOCK OEM...
EDIT: sorry i read now "Chinese Brands dont have FRP." so i can install directly OPENKIRIN rom without FRP check . My bootloader is unlock

On the 'Chinese' Oreo there is no OEM unlock option in Developers Options, and OEM/FRP always stays unlocked - please consult HWOTA7 OP instructions.
OEM/FRP stays unlocked also if going to Open Kirin ROMs and back (if f
the required installation procedure is followed)
Check in Fastboot, maybe only your Bootloader is locked, and you just need to unlock Bootloader again in Fastboot

Ok, be careful to follow OpenKirin installation guide
Btw, there was a trick to re-enable hidden OEM Unlock option in Oreo, post in the HWOTA7 thread:
https://forum.xda-developers.com/p9...date-tool-hwota7-p9-eva-t3820849/post77296996
With root, open from eg MiXPlorer:
/hw_oem/prop/local.prop
find and uncomment the line (remove trailing character #):
ro.frp.pst=/dev/block/platform/hi_mci.0/by-name/frp
Then reboot, open Settings/System/Developer options and find the belowed OEM Unlock option (see attachments)

Phone locked, FRP unlocked

I have a P9 (EVA-L09) branded to 3Ireland. I asked the service provider for the unlock code and got this:
Hi there,
Thanks for your recent unlock code request.
Below is the unlock code for Huawei IMEI 862836031485752.
Your unlock code is 1738262161041091. Please find instructions to unlocking your phone or modem below.
So I put a vodafone SIM in the p9 and it asked for the unlock code which I entered. My vodafone SIM works fine so the P9 is SIM unlocked.
With a view to installing LineageOS, I enabled Developer Options, Enabled OEM unlock and USB debugging. I then powered off the phone.
Holding the Vol Down button, I inserted the USB cable and the P9 restarted in Fastboot&Recovery Mode.
However, it says, in green, Phone Locked, and, in red, FRP Unlock.
I guess I have to unlock it to install TWRP but how do I proceed?
TIA
Dermot

You mean your mobile service provider?
If so, they gave you SIM unlock code to make your phone open for SIM cards from other operators
But that has nothing with the unlocking the Bootloader - what you see in Fastboot and what you need for flashing is about unlocking the Bootloader
Operators don't provide/sell the codes to unlock Bootloaders - rooting, custom ROMs are not in their interest
In the old days, Huawei provided (for free) Bootloader codes. They stopped and for the new phones made it really hard to unlock the Bootloaders, for some even impossible (at least, yet)
For the old P9 you can still buy a code from e.g. DC Unlocker (use Google)
But then, be careful, read the guides first - this mistake with buying a wrong code was benign while flashing an interviewcompatible ROM can brick your phone.
E.g., you are most likely on EMUI 5, and you cannot use any GSI ROM but only ROMs that were ported and adapted for P9, EMUI 5 ( Nougat firmwares). Also, if the ROM instructions say it is for P9 but EMUI 8, it is not for your phone (unless you rebrand and upgrade to Chinese EMUI 8)
It's not, take any AOSP or GSI ROM from elsewhere and flash to Huawei. If you are new in the game, go to the P9 Custom ROMs section here on XDA and read the OP posts to make sure you fullfil the requirements before you flash.
Be aware that most of those threads are 'dead' - early flashoholics long ago moved to the newer phones. Few remaining who stayed with P9 (usually as a second phone), upgraded to Chinese EMUI 8 (Oreo), and you can find them only in the few still active threads. Be careful and good luck
You can get one using dc unlocker for 4 euros. Just jut it down upon getting it. From there its smooth sailing on TWRP. You have to reinstall twrp from time to time if you are on stock though
@zgfg, I greatly appreciate the clear and comprehensive explanation. Very helpful.
 @Bill, 4€ is a reasonable price to pay for an old phone.
Thanks you!
