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.

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

[OTA] Huawei Mate S Firmware C432B321/C900B321 [MM] [Beta] - FRP Unlock enabled!

A few days ago some users enrolled in MM beta program started receiving new B321 OTA, so I flashed it on top of my B303 MM and so far all good.
Apart from feeling really butter smooth and including WPS Office, Developer Options now again include OEM Unlock option(FRP unlock), solving the no bootloader unlock on MM issue.
Be sure to be on B303 MM stock recovery, extract the \dload folder from zip and place it on root of external SD card;
Get into Advanced Project Menu by dialing *#*#2846579159#*#*
Go to the bottom and select "HOTA Update"
Wait for reboot, EMUI will verify, install and optimize -took about 15 minutes, so be patient.
What I noticed is that on B321 Advanced Project Menu is gone, only standard(*#*#2846579#*#*) is available.
B321 OTA Update: https://mega.nz/#!t5EhnBQK!ewPCJtBvSd3kWOc2DBmL83poB8Lo1oXzHSguE2TIWbo

hi, in dload folder, we have two files. which one should we use?

put the hole zip into dload and start the hota-update

Hi.
So i updated to this firmware and got the unlock OEM option, and i unlocked it, got into fastboot mode (well the FRP lock screen that showed b4 when i didn't have the oem unlock option). I did the fastboot unlock process with the oem unlock key i got from Huawei website and it said it unlocked sucessfully, but i have no changes, everytime i try to go into bootloader it says that it is FRP locked :/
Any ideas?

Isn't FRP unlock different to bootloader Unlock?

Well basicly i get the same screen as if my phone was still FRP locked :s even tho i enabled oem unlock in dev settings..

You must activate the "Unlock OEM" option, reboot into fastboot and make sure you have "FRP: Unlocked" in red text. Once you confirm this use the bootloader unlock key provided by Huawei.

Well for me it says FRP locked :/ even tho i enabled oem unblock.

Battery consumption seems a little higher on B321...will need to keep an eye on it over the next few days

If you mean bootload unlock key yeah i have done it. Still only screen i get is FRP locked

If in fastboot screen(picture, maybe?) you have BL unlocked/FRP locked I understand you have previously unlocked BL while on Lollipop and then somehow FRP re-locked again, maybe wrong TWRP restore...

No thats the thing i didnt have BL unlocked when in lollipop

I have managed to update to b321 from b303 version with little / no issue. Everything seems OK apart from a small annoyance - the haptic feedback for navigation buttons has stopped working. I've checked all settings and all seems OK. This was working fine on b303 so maybe it's a bug? Anyone else experiencing this?

I'm not sure if it's a bug but I prefer it without the vibration....I was of the understanding that the bug was that it couldn't be turned off in lollipop so I think if anything it's fix.
Battery drain is my biggest concern... On mobile data it's appalling...can't wait to go back to lollipop

I've checked this on my honor 7 and seems to work ok (e.g. haptic feedback for navigation buttons works) so I'm pretty sure it's not correct on mate s. I'll try factor reset and see if that cures the problem. - unless anyone else has any better ideas

So I am still on 303. will it be possible to flash the 321, then unlock the bootloader, flash custom recovery and thereafter restore an update of someone that provided a clean lollipop build via twrp?
As long as there isn't official 6.0 I would really like to get back to 5.1.1 xD
But my guess is we I still have to wait for a rollback firmware...

This error was also in lollipop version. try to switch it off in settings reboot and the switch on again and reboot and it should work like you want.

@bgx thanks for suggestion. Tried that and still no joy. I suspect it's a bug tbh. I'll try a factory reset tomorrow and see if that cures the problem. Not a massive problem but annoying as hell.

[Solved] Any way to unlock FRP after OTA update? (P10 Lite)

Hello!
I recently rooted my new P10 Lite before version B124 was released, but then I decided to update my phone from B102 to B124 by flashing the recovery image from the Update file and then updating via OTA with the full update files.. The phone updated successfully but yesterday I used adb to boot into the bootloader in order to flash TWRP but noticed that FRP is now locked and i cannot flash TWRP without getting command not allowed error.
I also tried unlocking the bootloader (just in case it was locked for some reason) using the password i got from huawei but even that gives me an error. The enable OEM option in developer settings is greyed out since after the update and is till greyed out even after clearing cache and factory resetting the device. Now is there a way for me to unlock FRP again in order to flash TWRP? Or maybe another way to flash TWRP. Hopefully someone knows a way.

Use DC Unlocker.
I used it to unlock my bootloader on P9. Works perfectly.
They do FRP unlock and supports P10 Lite.
Costs 15 credits so 15 Euro.

Thanks bro. Wish i saw it before spending 15 credits in DC unlocker. Even after removing frp i am still not able to tick enable OEM unlock in developer settimgs or flash twrp in fastboot. Only thing on my mind right now is to lock bootloader and see if enable oem unlock option will be available after that.

Bootloader Issue | FRP Lock | Root Guide

UPDATED:
Issue has been solved
( i buy 4 credits from dc unlocker and use HCU to read my boot loader code )
yes i know this is all from dc unlockcer yes they , unbrick my P9 but they also
changed the boot code when you flashed the rom via DC phoenix
im suspecting it that way .
Hello guys. Debranded P9 here
Nougat C432B386 Eva-L09
hw eu :country vendor
Bootloader unlocked and FRP lock
my device gets suffer from a hard brick
and recovered by DC Phoenix. In order to
have a Stable Nougat Firmware i decide to
debrand my phone ......
1st attempt : flashing the (.dgkmts AL10 chinese rom)
after flashing the chinese Al10 firmware
from DCUnlocker (.dgkmts) the device boot and
can be flashed into original stock rom
but the first attempt fails because my
vendor comes from a different build
2nd attempt: flashing the (.dgkmts AL10 chinese rom)
but this time, i decide to wipe NVME and OEM
after booting into system and checking my device
details my IMEI stays the same but Serial No is missing
so i had to use HCU to write my IMEI and Serial No.
and obtain a new vendor from hw eu
after booting system, I start to forced update the
EVA-L09C432B136
then i unlocked my bootloader at this stage
using the same bootloader code from Huawei
FIRMWARE:EVA-L09 C432B136
( please focus on this, i already unlocked the bootloader​
here , and allow the oem to unlock )
status : bootloader unlock
frp unlock
the process is successfully done and after that
i check my device details and perfectly debrand
my P9, after a minute it received an OTA update
from Huawei System Updater ( C432B186 )
I update into it and reboot and received another update
again C432B322 ( Nougat-beta version) and then
received the Final Build C432B386
SUMMARY STAGES:
bricked and wiped oem info / SN rewrite using HCU
1. AL10 Chinese rom >
2. C432B136 ( stock firmware)
( do unlocked bootloader )
3. OTA C432B186
4. OTA C432B322 ( Nougat beta )
5. OTA C432B386 ( Nougat Stable)
status : bootloader unlock
frp lock
I'm into that version C432B386
and now im having a trouble here
flashing the original bootloader code
command : fastboot oem unlock xxx-xxxx-xxx
it says : wrong password
failed to write the command
" is it possible to obtain a new bootloader code ?"
i don't know why the boot code changed even though
i use it in unlocking my Bootloader and it succeed
2nd scenario:
when i try to go to developer options and
go to Allow oem unlock
so that i can be able to obtain FRP unlock
but it is greyed out.
" i've read that if you're on Nougat and you are already
in unlocked bootlader, you will have this issue "
the possible way of unlocking FRP is relocked the
bootloader first and the OEM UNLOCK option will
come out.
i guess the solution is finding a new Bootloader code
but "how?" does anyone knows this?
3rd scenario: flashing new recovery
( expecting to have administrative rights )
i try to flash also the twrp nougat version
but it says verification error
command : fastboot flash recovery twrp3.1.0-3-eva.img
failed
i don't want to end up bricking my device again
I'm having a hard time to resurrect this and I don't
want to happen it again, I'm busy with my work so
i have to asked you guys, finding a best way how
to fixed this..
if someone is having a same situation like me
please participate on the thread and or someone who
already fixed this kind of issue please give us information . thank you !

[GUIDE] How to unlock bootloader of P7 L10 in 2018 (Without Huawei unlock or paying)

I have attached my unlocking software, if you are still on android kitkat you can immediately unlock and if youre on android 5.0 or 5.1.1 the software will help you downgrade, once you have unlocked the bootloader you can upgrade back to the new software.

Thanks, working trough it on *nix atm, i tried the method described to unlock the bootloader officially, or so i thought, the method has been removed from the Huawei web site. Registering an account was required to obtain the unlock code but this resulted in me having to editing the page to add my country number as the country was not listed to get the sms unlock code.... At the moment i am preparing to hack the device but have not currently found the file for the B856 firmware it's running. I do not want to for example downgrade the baseband, the baseband will need to be hacked a little bit in order to get Android 7.x, i believe is the case.
Rooted my system and backed up all the partitions. Everything but userdata that is,

This software is for the p7-l10 so im not sure if it will work for l12 but it may work, just download it, connect your phone via a usb cable, run the bat file and then choose the option you want from the listed options (unlocking bootloader)

As I can root the huawei p7-l12 the apps to perform this procedure are automatically blocked, I mention it because in the executable root appears necessary.

Hi, I can confirm that this method works for the huawei p7-l12.

For this to work you have to be rooted! Make sure you are rooted, and if you are, open up cmd and write adb devices while the device is connected with a usb cable to your pc and give me the output

So I am stuck with this at the moment. To unlock the bootloader, I need to have the phone rooted. And to be able to unroot, I need to have an unlocked bootloader.
I already tried to downgrade back from 5.1.1 to a lower version, but I was not succesfull.
How can I get an unlocked, rooted P7?

That is nice, thanks.
Howeever I need to get back to 5.1.1, while keeping it unlocked/TWRPed, will OTA work, or i need to do incremental flash through TWRP? As i understand doing it by UPDATE.APP would lock the bootloader again?
EDIT: never fk mind.
You know what... DC Unlock really gives you the code for 4€, and it takes 60 seconds.
So after 5 hours of downloading and flashing roms, now I suddenly have TWRP and Magisk after 5 minutes and easy instructions. Couldn't recommend more.
