How can i Root P8 LiTE without unblock bootloader? - P8lite Q&A, Help & Troubleshooting

Hey!
First of all my english is very bad, I'll do the best I can .
Some weeks ago (2-3) I received the phone , Huawei P8 Lite Android 5 (Vodafone ROM).
So i rooted with KingRoot and all was perfect.
Few days ago my friends told me to upgrade to 6.0, thats what i do. But surfing @ inet everything I've read is to Root with Bootloader unblocked..
But i cant unblock my bootloader cuz Huawei site says: "The Huawei ID used to apply for the unlock code has not been used on the device for more than 14 days."
So i downgrade to Android 5.0 SPAIN to try to root... butt.. CANT now, KingRoot says unavailable to root cuz version is "hi6210sft" instead of ALE-21, my version is DUAL SIM i dont care about double sim , i only want 1 lol.
The question is.. can i Root my Huawei P8 LITE (Compil.:BalongC50b311) without unblock my bootloader? I can upgrade/dowgrande all version if needed, the only think i need is Root.
Thanks you very much and sorry for this ****ty post (;z)
Regards

First of all, your rom in your Phone is not for Your Phone.. That word "balong" is "you have bad rom" flash right rom, then it could be possible to make root again like you already did

Yea, but cant flash the rom without bootloader unblocked true? :/
So, BALONG = some is wrong

im not sure, but i think you easily can flash stock rom without unlocking bootloader... you need just right rom image. It will be like "P8Lite_C432_B190.APP" that .APP is very important, because only with this you can flash it (just put it into root of your phone turn off device then press volume up and down in the same ime and urn it on. release after you see huawei logo)
yes, balong means something is wrong, but sometime your phone can work normally, it just rom for different region (for example China)

Okay thanks you, ill try to ask for the correct img to my friend's, only i've to do is search and try to find the correct ROM then flash with what soft??

You dont need aby soft, just do What i describe in previous post... And I think you will need rom like b130 or similar low number... Then u can upgrade to 170....

I Need the stock firmware for huawei p8lite ALE-L21 with build : c185b160

Forgive me for bad English. I bought a p8 lite ALE-L21 in Egypt. once unpacked and switched on the device, it received two updates one after another. I don't remember the first build. but the current build is ALE-L21 C185B160.
I unlocked bootloader and rooted with king root then flashed TWRP. while removing some bloatware I removed some important apps by mistake.
Now I want to go back to the official untouched build firmware to have these features back.
I searched for this build B160 everywhere but all I found is B170. NO B160 anywhere.
I tried to flash the B170 but FAILED
PLEASE HELP ME FIND ALE-L21C185B160 Build.
any help will be appreciated.
thanks
Vampokin Sent from ale-l21
you need to flash C185B120 rom, then you will receive un apdate to B130 version then an another to the B160
all you have to do is to search for the rom and flash it via fast boot mod

Dude, have you found any solution yet?
I have the same problem and Im Kinda stuck there ..
I read somewhere that I can flash the European version "ALE-the L21 V100R001C432 B052" which I'm not sure whether it will work ..
Now I need a stock Rom to fix all the mess I made.
Plz let me know if you could fix it!
Edit: if B052 didn't work just try this one it should work "Huawei ALE-L21 Firmware(Android 5.0, EMUI 3.1, C185B131, United Arab Emirates Rep)"

Still downloading the Rom ....
Enta 3arf elnet 3ndna zft :crying:
Will keep you updated Insha'Allah and so you do too .. just let me know if anything of this worked for you .. or maybe other.
I didn't work for you, then you didn't know how to do it
I did it my self on my device and it worked like a charm
Any way, I created an auto flashable version for this rom, juste download it, plug in the phone with usb cable into your pc ( of course make sure usb debugging is on and drivers are installed and your bootloader is unlocked ) then juste click the FLASH-ALL file and the phone will reboot automatically into fast-boot mod and flash the rom.
Of course you will loose your data, also your IMEI? but no worries, juste update to B130 version via OTA ( go to update and search for an update and you wll find it ) and you will get your IMEI back. then you will receive the B160 update via OTA too.
here's the link of the rom I made : https://mega.nz/#!ZIkXXRDQ!_jvnDA3_0b2zxNF3atgqM3HBq-0NgMIFQtADQfJLtMs

So what if my bootloader is locked?
I have rooted my phone without unlocking the bootloader .. it's not a full root but I can't get rid of it .. the only way is to force flash the official firmware which I couldn't find anywhere .. If maybe I have the OTA update B160 alone I guess it might solve my problem but there isn't such thing on the internet.
Well anyway I finished downloading the full B132 now and I'll give it a try tomorrow morning and see If it will work .. If not .. I'll try the one you made if it works with bootloader locked. (I don't know yet)...
One last question plz: if I want to upgrade to marshmallow 6.0 .. from where should I begin?
I know it's only for the European version which starts with B052 => B170 => B188 => B524 etc...
So is there any working method to get to the B524 directly from our version without having to do it all from scratch like that?
And can we actually flash the European version instead?
I.I'm Sorry but huawei is really confusing and playing dumb with us.

no unlocked bootloader ==> no rom flashing on the phone

This should not upset you.

Thank you for your answers..
But I just found something weird that I don't understand ..
I booted the phone in fastboot mode and found "phone is unlocked" while I haven't actually unlocked the bootloader.
I only followed the tutorial on this thread ..
http://forum.xda-developers.com/p8lite/general/tutorial-how-to-root-bootloader-unlock-t3314786/page4
My question is ..
Is it really a full unlocking?
With having this, could I make a full root by flashing supersu files through fastboot or flash a custom recovery?
Is there any way to relock the phone as I haven't unlocked it officially?

Bootloader results unlocked (as you can see) but's acts as locked.
System partition will be mount only read mode, so you cannot update supersu anymore.

Help Requested

Hello everybody,
A few weeks ago i update my P8 Lite from B181 to B550 but i got the Balong bug but since very people said to me that this bug don´t affect the daily use of the phone, i don´t mind with it. But a few days ago, my phone from nowhere start to install a update ( i don´t selected anything) and after the update my phone was tottaly clean, like, no apps, no files, nothing! the phone memory was completly gone!
Now i´m think is better to go back to Stock ROM, but i need help because some people said that install via local update the original firmware works ( i don´t have the option to choose local update like i have in B181 before update) and other people said that the process is a little bit more hard.
So, can someone help me please?
My Phone is locked to Vodafone Portugal (Single SIM). Like a said before update to B550 i was in B181
Thank you everybody and sorry for the bad english :good:
First of all you b550 is for dual sim,you have single sim so you need b551.
Second b550/1 it's stock rom,it's just stock 6.0
Balong bug appears when you flash a firmware that is not for your country so in order to get rid of balong,just flash the file from vendor/custom folder that cames in the archive of your last firmware downloaded.
Is your bootloader unlocked?

Stubborn P9 Lite wont flash any firmware [help please]

So, I have a Huawei P9 Lite (VNS-L21) and I have a problem: when I boot it up I see the "Your device has failed verification..." message.
I did a hard reset (factory reset) but when I boot it up it asks me for a password and the keyboard doesn't work.
I googled around and I found a lot of posts and I tried everything, no luck.
My bigger problem is that I don't know my phone's model number and firmware version. So I cand find the proper firmware to flash.
The only thing I see is the VNS-L21 on the back. Also, I took the back of and I saw two codes (I don't know if it helps): GA20 and 160521H2
Also, (with DC Unlocker and the the phone in fastboot mode) I managed to get the IMEI and serial number. The SN is: BUC4C16519008689
Now, from many other XDA posts, I know that I have to download the update.zip archive, extract the update.app file and add it to a micro sd card in a dload folder, press vol up + vol down + power and the updte will begin.
Did that but the result was "Software install failed".
I tried to use FirmwareFinder (from Team MT) but I didn't know what firmware to use, so I used this page: https://romfirmware.com/stock-rom/huawei/huawei-p9-lite-vns-l21/
I belive (from checking my IMEI here: https://imei24.com/imei_check/Huawei/) that my custom region provider code is C432 (Europe).
So I searched on the page for a VNS-L21C432B... firmware version, but I don't know what version to choose.
I attached 4 photos so you can see what I'm talking about.
So, any ideas on what should I do next?
Thank you!
Hi, try my way. https://forum.xda-developers.com/showpost.php?p=77307223&postcount=30 Just pick CxxxBxxx that suits your model. Kinda wondering how you don't know your phone model, did you steal it lol.

Thank you for the info. I read that post and did a little bit of searching but, as I said, the issue is that I don't know my phone's Cxxx code 100% (not sure is the European version, as far as I know it might be imported). Also I don't know at all the Bxxx code.
So what do I have to do in order to get the right one?

Also other thread said that I need the bootloader code but I can't get it from the phone.

Without unlocking code you can't unlock the phone
your bootloader is unlocked but the frp must be unlocked to , the problem is that to unlock frp must boot your device. The only rom that may fix your problem is this l21c432b370 FullOTA-MF-PV it is the PV, with this rom i unbrick my p9 lite
This rom is for L21C432B370 if your model is l31 you may brick it more or not work at all

My (other) problem is that I don't know for sure what exact model is because I can't access the settings. All I managed to get with DCUnlocker is this:
Code:
Found Phone : HUAWEI VNS-L21
Model : Huawei phone in fastboot mode
Firmware : NRD90M test-keys
Is this info going to help me?
If I try your l21c432b370 FullOTA-MF-PV rom can I do something that is irreversible?

Google how to root your phone, you need imei code maybe. I can't remember anymore. And remove IMEI and S/N info, it's sensitive.

PV means point version and is used to move between android versions
If the readings are correct your rom is NRD90M test-keysand you have the l21 , so the NRD90M test-keys means that its problematic rom (it come up when upgrade from android 6 to 7 in huawei phones , if you look here you will see to many problems like your, some are lucky and fixed some are not so lucky) , what do you mean irreversible when you have a bricked phone? you can download this rom and try to install it with dload directory , i thing its the only way that you can try

Hello dear,
I don't know if the 'demo' version can be unlocked (bootloader code),
but if yes then you can use @k1ll3r8e's TOOLKIT to rebrand to another region (cust)
like C432 european or C636 asian, etc... you just need the correct files.
Once you rebranded then will be possible to upgrade to nougat via Firmware Finder app
or some other tool/script.
P.S.: What version of p9 lite do you have ? L21-L22-L23-L31-L53 ?
Cheers

Well, i think you can rebrand to the european firmware (C432);
both single and dual sim oeminfo files and matching firmwares (B160&B161) available. (see the attachments below)
But, like a told, you need to unlock the bootloader first.
P.S.: you already risked to brick the device trying by your own,
using the toolkit and doing something wrong could turn the device in a paperweight....beware what you do with your device !!!

Dear friend,
I agree with you and completely opposed to paying, but
I believe there are no other ways than giving up a couple of beers and
using DC-UNLOCKER which at the cost of 4 euro reads the bootloader code.
Obviously you only know if it's worth it and definitely remains your choice.
For everything you should / want to do there's a guide you just have to follow.
If you encounter any problems or are unsure about how to do,
you can always meet the community or me in this topic.
I wish you the best !!

Update P9 Lite from Android 6 to 7

Hello everyone, I have a P9 Lite which was issued from Vodafone Europe (originally VNS-L21C02B128), and I'd like to update it to Android 7.
Since none of the stock ROMs I tried would pass the verification when updating via the Project Menu, I found and flashed a newer Android 6 which works fine apparently - build number is currently VNS-L21C900B170.
Trouble is all of the newer ROMs are still not working. During the verification phase, it says they are not compatible with the phone.
Any ideas what is the simplest safest way to get to Android 7 ? Thanks for the help.

Have you tried Service ROMs?

- Unlock the bootloader
- on android 6 rebrand to C432 global
- in TWRP install fullOTA-MF-PV VNS-L21C432B370
- then you can upgrade to a higher version by installing a Service ROM via dload method (it will lock your BL again).
The problem is probably with your current build number - the C900 is fake firmware, incomplete or incompatible. I'm afraid you won't be able to unlock the bootloader or rebrand the phone with this build.
Hello Alf, I did try VNS-L21C02B346 but it didn't work, both with the original and the newer ROM. I also tried the "SERVICE Full Repair VNS-L21 C432B381" from here, also with no luck.
The current B170 ROM was labeled as "VNS-L21C432B170" on the site I got it from, but now it shows as C900. This one updated with no problems via the Project Menu upgrade command, the only one to work so far...
I will see later about unlocking the bootloader thanks.

You can't install C432 on C02 and vice versa without changing oeminfo, that's why you now have a C900 region and failed verification.
Thanks but I don't know hot to change oeminfo. Can I use SRK Tool ?
Also is there a free way to unlock the bootloader ? Is it this one ?
Does the phone have to be dissasembled, or is there a software method as well ?
Is dc-unlocker free for phones with android 6 and 7 ?
