Help rooting Huawei P7 L10 B839 Lollipop 5.1.1 & UNLOCKING BOOTLOADER

Hello guys, I need help with this and I know a lot of people need info about this too, I want to root my Huawei P7 L10 with Android Lollipop 5.1.1 (P7-L10C900B839). I already tried with ROOT GENIUS and it didn't work, I got a message something like right now there is not root for my phone, and another saying that the phone disconnected from the pc WHICH IS NOT TRUE. So, could anyone help me please? Also, I don't want to unlock the bootloader, I may be wrong so you should correct me if I am but I think if I just want to root I don't necessarily have to unlock the bootloader, I just want the root for a few minimal changes (to change the font since EMUI 3.1 doesn't let us do that and apply the new emojis to my phone changing a system file). So yeah, could anyone help me, I already checked the other threads and they only suggested a procedure involving unlocking the bootloader...so HEEEEEEEEEEEEEELP PLEASE :crying:

there is no other way than unlocking bootloader if you want to root your phone..
for b839 you need to replace the stock recovery with the newest TWRP custom recovery..
through this you can flash the super su (should be available as a zip-file)..
after that you have to delete the set_immutable.list by installing busybox and through commands by a terminal emulator..
when you have done these steps you should have successfully rooted your phone..
if you have read the threads entirely you should have read these information as well - because this had been adviced many times since the b805 beta..
for replacing stock boot or recovery it is always neccessary to unlock the bootloader, otherwise you will always get a "failed" if you try to flash a custom one..

Ok thank you for clearing this to me, I wasn't sure so I asked. Now I wish you could tell us step by step how to unlock the bootloader of the B839, I read the [GUIDE][HOW-TO] Unlock Bootloader Huawei Ascend P7-L10 thread but they talk about the B121, B126, nothing about B839
I used to root my phones long time a go, so I have a little experience, but I have never unlocked a bootloader or rooted a huawei, this is my first huawei. Could you please help me with this? I Know there are people looking info about B839 too. Thank you.

It's really simple, once you've unlocked your bootloader and updated to the latest stock firmware, just flash a custom recovery using flashtool (flashtool flash recovery RECOVERYNAME.img) and flash supersu zip in recovery.

http://www.mediafire.com/download/wl1gua834qefkvy/recovery_cwm_emui3.0_B609.img

Ok, but I don't know how to unlock the bootloader part sorry, as I said I have never done that. But the other things you said and the other person above about the flashing a custom recovery and flashing super su zip I think I don't have any more questions, although I don't know why in the second link you sent it says emui3.0 and B609, it will work with my lollipop 5.1.1 emui 3.1 and B839? because downgrading is not an option

Hi everyone!
I just purchased a P7-L12 and I just upgraded to Lollipop 5.1.1. I'm very sure this update locked bootloader. Previous versions have unlocked bootloader.
Does anybody know the steps to unlocked this?

on huawei website should be a button for unlocking bootloader..
it is a small one..
just so the steps the website asks to do and you should get clear instructions how to unlock your bootloader..

Here it is: http://forum.xda-developers.com/ascend-p7/general/guide-unlock-bootloader-p7-l10-oem-t3062851
I just tried the dialer code thing and I got this:
FAILED (remote: data parse fail)

boss follow these procedures
1- Download adb or fastboot programs and save them to c: partition on your computer.
2- go to the file were you download the programs.
3- Press ctrl button at keyboard and right click at the mouse at same time.
4- You one option I don't remember exactly but it says something like open file here with adb.
5- You get the cmd screen for adb then you should type the following:
a- adb reboot bootloader.
b- fastboot oem unlock UNLOCK CODE.

It's not going to work, you need to request huawei for unlocking code

yaaa this is what I told him he needs to have unlock code that's why I capitalized this word.

Just go on huawei website and find about bootloader unlocking code. Its very simple

This is the link to unlock bootloader:
http://emui.huawei.com/en/plugin.php?id=hwdownload&mod=list
There is a button Unlock Bootloader. Fill the form and then the unlock code will be generated!

I always get "server is busy" or something like that....

Try to login with your facebook-account. That worked fine for me

Manual update P10?

Anyone succeed with manually updating P10? I have tried with no sucess.
Old method is not working.
Thanks

No but did you made the dload folder with the update.app file and then booted into the stock recovery mode?
I woudnt know any other way since they removed that from update settings : |

I tried that, does not work.

You can't manual update the P10 or P10 Plus, since it requires an online check.
They removed the ability to manual update via dload methode.
The only way at this moment is to use FunkyHuawei!

What about Firmware finder? I've tried this as well but I only get download failed, even everything is done as it should.

Hey,
I am working into this direction and got some promising results already. I am testing two more things during the next days (so that I can be sure my Stuff won't break your phones) and hope I can share my findings with you early next week.

Good to hear that. :good:

So, it is not possible to update, even the firmware matches your corrent model/brand?
I finally found the FW for VTR-L09C109, but when using dload method I get "Installation failed".

No, it is not possible. Huawei did something with emui 5.1.

Not always correct. It depends on the local country laws you live in.

And also if you follow the instructions you end with LOCKED Bootloader so no warranty lost

Is it same with P10 as it was with P9, tha it say relocked instead locked bootloader, when you lock it again?

nope : Phone LOCKED
FRP unlocked so they cant see the difference they can only find out if they check if you got the bootloader unlock code.but you also could request the code and dont use it.

Any progress here? The update has been out for months in other regions but I still haven't got anything here in Sweden :/

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.

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..

P10 not turning on after update!!!

Hello.
i have a Huawei P10. [VTR-L29 9.0.1.159(C185E3R1P9)]. I updated it using hisuite and firmware finder via erecovery 2 weeks ago, then recently i tried to check for updates in hisuite, an update is available, with the same build number(developer) with size of 880mb and i updated it, after completion of update, phone restarts, verify installation packages and proceed with update installing, after 99% phone restarts again and not turning on itself, i tried manually turning it on, not successful. so I tried plugging it in my computer, hisuite detects it, and system recovery is the only option. i tried but it failed, and should be taken to the service center.
What should I do?
-my phone was purchased abroad
-warranty expired a year ago
-i dont have the box of it and the imei infos.
If anyone can help me, please I need it. THANKS

Hope that bootyloader still working, else there's a chance for you to get another phone.
If I had to go thru what you have today... I would try to flash Emui 9 based RR or Los just to revived while enjoying the pure android interface.
If all else fails... Go back to basic maybe there is a thing or two that you've missed

I have found some videos and Threads saying some Huawei's Tool can read Bootloader Code.
Is it true?

4 Euros was enough for me two years ago (also P9).
Don't know if prices changed, but they have contact page and ask them directly

Brother, I have bought 4 credits from Dc Unlocker and successfully read Bootloader Code, Now will you please guide me on how to unlock the bootloader and rebrand for upgrading to Oreo?

First, keep your code (on several places, even printed on the paper), it is good for relocking/unlocking (you never know, some actions may lock the Bootloader back) for the lifetime of your phone.
You don't want to go buying the same thing again
Assuming you know how to enable OEM Unlock in Developer's menu and you are a little familiar with Fastboot, it is simple to unlock the Bootloader
Code:
fastboot oem unlock <your code>
If not familiar, and if not clear as below, search on Google how to:
- enable Developer menu by clicking 7 times to the build number in Settings/About
- enable OEM unlock in Developer menu
- install "Minimal ADB and Fastboot" to Windoze (smallest, self containing package with everything for ADB and Fastboot)
- reboot to Fastboot: keep pressing Vol-, then Pow button
Unlocking Bootloader triggers hard-reset, wiping also Internal memory. Backup as much as you can - use Google account, HiSuite, WA own chat backup, copy DCIM to PC, Contacts can be exported to vcard file, etc
Rebranding to AL10c00, upgrading to b540 Oreo, applying the neccesary Network patch to make SiM card(s) working - all is in deep details explained in the OP posts:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
Read two times before you start, and keep the instructions opened on the PC while doing - wrong moves can cause (soft) bricks

Thank you, Brother, I have done all procedure and my device is now at Oreo, Build EVA-AL10 8.0.0.540(C00).
After doing all the required steps I have flashed Huawei's Official Recovery and enabled OTA, after that I have received an OTA update of 3 MB, Should I install the update or not?

It is safe, just some Patch02 (never found exactly what for).
If you don't mind, you can skip (you can disable OTA - see in OP)
If you go for, you must first flash back the stock Recovery, hence not having TWRP. Not sure anymore, maybe also stock Ramdisk, hence not Magisk
Patch02 will not affect Network Patch or Face Unlock (cool add-on, see OP)
If you didn't apply Network patch yet, etc - then accept Patch02 and continue with OP instructions.
If you already rooted by Magisk, then don't bother with Patch02, too much trouble preparing clean sheet for OTA and rooting again

I have already applied Network Patch, See my both SIM is working.
Right now I don’t need Root so I'm skipping Magisk.
I just want to disappear the update available Notification, if the update is Safe I'll go for it.

I'm from Bangladesh, some Operator in our country introduced VoLTE.
It seems there is an option called VoLTE after upgrade to Oreo. Is it really works?

Nope, VoLTE does not work.
Everything else, like location sharing and Ok Google are fixed with Network patch, but not VoLTE.
The guy who did the whole majestic work went tired (although he believed he was close to fix VoLTE) and gave up. Later he upgraded to newer Huawei devices with Pie, etc, and eventually moved away from XDA

Brother, How to remove the warning when Phone boots "Your device has been unlocked and can't be trusted"??

It's not possible to remove the warning on booting "Your device has been unlocked and can't be trusted" (IMO, it must have been commented somewhere in the OP) - that's price for the unlocked Bootloader.
But you must not relock Bootloader - it would trigger Hard reset, removing Network patch (even worse, it could also cause soft brick if TWRP or Magisk are installed)

15 credits for unlock in fastboot mode (not pay over sms)
