when i am going to the site where i can get the code and i presson Unlock Bootloader i have to login again.

Obviously you have to login again, try to get your unlock code again. For the product ID you can try to generate it with a tool, http://rootjunkysdl.com/files/Huawei P8 Lite/Huawei Product ID Generator.exe, but I can't tell you if it will work.
If you manage to unlock bootloader you can recover your phone, otherwise I can't help you. Good luck.

Huawei tiols can unlock in fastboot I think...

well, without unlock code, you're pretty much out of luck. but there is something else you can try, search dc unlocker on google. i don't know how that works, but seeing reports from other users it does work

I got my code with DC unlocker.
It does work, but its not a free service. It will cost you like 5 bucks or something like that.
Essentially, it is sometimes tricky to use the Unlocker. The phone has to be recognized by it. After that, it is easy to use.
Also... just SAVE your code! Just put it in a document and save it in a cloud drive. It really isn't that much effort.

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.

Did you unlock the bootloader? Does the device work?
As said, unlock the bootloader.
Had the same problem with mine. Brought my phone back to the shop and received a new phone after two weeks.
Sent from my HUAWEI VNS-L31 using XDA-Developers Legacy app
1. rollback from N to MM and then update to N (bluetooth not working and some features...)
2. its red warning, bootloader unlocked half year ago, but now NO START, must push on/off then start phone
Its possible change oem info without twrp and root? Because i have now 2 sim version and i need only 1 sim version VNS-L21
This happens when the bootloader is locked but something in the system is not stock.

It's because you've installed an unofficial firmware in your device. You must downgrade.
Solved!
1st - thanks for advices
Soft was official, but problem was in oeminfo (from lineage Meticulus) still, i dont know why... A was downgrading to 161 and flash twrp and flash oem in twrp... Now everithing is ok! Thanks!

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?

root? how do you think root will help? and who deliberately made this? i never thought that, but now you said that...
which version are you now?
@ba_baracuss @sergio_f
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.
All the best guys :angel:

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:
Reading bootloader code...
No username !
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****.

Hello.
You can throw away 4 euros and try to use DC-Unlocker and read the bootloader code.
I don't think it works with newer phones ...
Read this post. :fingers-crossed:

Meticulus offers unlocking for a few bucks.

I think Huawei have stopped unlocking bootloaders. I believe you can pay third parties to do it, but I don't have any experience with that.
