Google Services don't work - Huawei P9 Lite - Huawei P9 Lite Questions & Answers

Hello everyone, I have a problem with a Huawei P9 Lite VNS-L31 .
The Google Services don't work: when I open a Google app (i.e. Google Play) the Google Login screen appears and disappears quickly, so, I can't login to Google.
This phone runs Android 6.0 with EMUI 4.0, with serial number VNS-L31C900B170... about this SN I read that the problem is this version of the stock ROM that "blocks" the Google Services and can't update to Android Nougat.
I tried to unlock the bootloader by using DC-Unlocker (because the Huawei's official service for the bootloader code shutted down) but I had a problem with the credits payment, so I can't unlock the bootloader now. I had tried to install some firmwares that suggest Firmware Finder 9.5 with the software updater, but none of the suggested firmware had work.
So, in this thread I want to ask if there are a way to install a "normal" firmware (like the C432, that is the european firmware) without unlocking bootloader or unlock bootloader without using DC-unlocker.

I'm having the same problem, somebody can help us?

Guys I would like you could recover the full functionality of your device ...
but I wondered how you did to have that firmware ( global firmware/C900 ).
In order to solve those problems you need to know the model L31 / L21, single / dual SIM and firmware in use before you had C900 firmware, branded/unbranded included in which region you live, because it also depends on this. Answer me these infos...
I suggest you take a look at the UNIFIED HELP THREAD for aid.
Look at post #6 ...
I can try to help you, better ask or re-read before doing.
Happy Holidays

The program that the post suggests don't work: first of all, the program don't read the bootloader code and for this opens the old website for requesting the unlock code, that is disabled. So it's completely useless. Ah, the program doesn't recognize my device, after enabling usb debug, installed hisuite and enabled manufacture mode (adb recognised it, the program not). So, are you sure that the program is a crap?

Don't know what you're talking about.
Link i posted you talks about update via dload folder AKA three button method.
If you refer to DC-UNLOCKER app and still interested in unlock bootloader read this post,
i will suggest to read the entire thread, then decide.
In any case the device is yours and you can choose what's right for you...
Good luck

Huawei Nova 2i - Cannot locate firmware for this specific rendition - RNE-L02C759

Hi,
Admin, please move is this is not the correct place for this question.
I recently got this phone, I managed to unlock the Bootloader and flash TWRP, but that is about as far as I got in my dreams to update this phone to Oreo.
I just cannot find the firmware for this phone, not even just to flash the OEM recovery.img back onto the phone.
The build nr is RNE-L02C759B141. Huawei Nova 2i
I'm in New Zealand
I can get tons of RNE-L02 firmwares but nothing with the C759 variant?
Can anyone help explain to me how this works, is it posible to flash one of the other RNE-L02xxx variants and how do you do this. I've tried the dload sdcard upgrade, but it keeps failing.
Thanks in advance.
Have you tried the Firmware Finder utility?
Btw, you need a bootloader unlocking code at first. But it seems that Huawei has closed its official web page for these unlocking codes.

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!

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?

Make sure, phone and FRP is unlocked. There are plenty of threads with unlocking and tools.
It's been some time since I tried to fix this phone because of some medical problems.
Now I'm resuming the work and I tries some stuff but no luck...

Please trust me, I've read a lot of "FRP unlocking" threads on XDA and I didn't solved anything.
Here: https://forum.xda-developers.com/showpost.php?p=68514977&postcount=6 I saw something that I can use Oddin, but how? And what firmware to use?...
Also other thread said that I need the bootloader code but I can't get it from the phone.
Any ideas please!?

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

By the "unlocking code" you mean the bootloader code? And is there any way that I can extract it or get it some other way?

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?
Btw, you said "it is the PV". What PV means?
Thank you!

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

P10 lite debrand is not receiving OTA updates

Hello guys,
I have been following the forum for a long time but it is the first time that I need to consult you. Basically, I bought a p10 lite as a forklift. Except that I had ordered it nobrand but it arrived branded vodafone. I have done all the necessary procedures and now it is nobrand but it is still at the WAS-LX1AC432B182 version without the possibility of updating because it tells me that this is the last for this device even if it is not true.
Checking from HiSuite itself, it tells me you are "using the latest official version".
What can I do to unlock the updates?

P10 Lite (WAS-TL10) Stock ROM files

Hello all,
I'm looking for the stock rom (EMUI 5.0/Android 7.0) firmware files for my newly acquired P10 Lite (WAS-TL10).
Bought it at AliExpress, was supposed to ship with Android 7.0, but got Android 8.0 on it.
Unfortunately I need Android 7 for the sole purpose of verifying some Huawei allegations in which they pretend my app is not working properly with HMS Core version lower than 2.5.3! A version you can't find anywhere on any devices, but those Huawei phones running Android 7.0!
I say they pretend because they've made-up all kind of new rules for the past months to just prevent my apps from being published in China, as explained here: https://www.3c71.com/android/?q=node/2784
Any help would be much appreciated.
This is the only Android 7 Stock firmware I could find:

Try to downgrade to Nougat using Hisuite (official and safe way to do the downgrade). A7 firmware will not help you, there's no way downgrade (with locked bootloader) . Try chinese Hisuite :
https://mega.nz/file/1p9xyIRL#bx1M6zXqtrR38okQd4YqkYvmLfRaOBDJ2snjd8W7kqk
If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower Oreo build version number doing the dload method (flashing Service ROM for your model and region).
Hi...
Like @-Alf- said you can try it this way. If it doesn't work for you. Search this forum for Service Rom to downgrade from emui 8 to emui 5. But be carefully by using any method. Make a full Backup of your System before doing any change. If you will downgrade to emui 5 for unlocking the bootloader. Better think about to use the Dc-unlocker for that. It will cost 4€ to get the unlock code. But its without risk to brick your device and it doesn't waste time to get it. You need to choose wat is more important for you.
So good luck

Thanks all, I was able to downgrade to EMUI 5.1, which allowed me testing very old HMS Core (2.5.2) somehow and its upgrade mechanism. Not sure I needed that device as it seems EMUI 5.1 didn't come with AppGallery at all, LOL.
Now I'd like to upgrade back to sell the device, but I haven't found a way to do so... Hi Suite tells me device is up-to-date, and OS system update tells me the same

I found a firmware, but it doesn't seem compatible ( Warsaw-TL10HK 8.0.0.371(C636)_Firmware_8.0.0_r1_EMUI8.0_05014HTC ) because upgrade says there is no update file on SD when I put the dload folder on it.
EDIT: That firmware contained zip files instead of .app, so I extracted the .app files and recreated the expected structure, and it processed the update using OS menu ( *#*#2846579#*#* ).
If any-one need the modified file, let me know.

After modifying the dload folder to have .app files (instead of .zip), the phone took the upgrade (editing previous post). New build number is WAS-TL10 8.0.0.371(C636).
I can now upgrade/downgrade between Android 7 and 8 for testing. That's pretty useful, so thanks to all.

WARSAW is the Name of the Phone...an p8 lite 2017 is called Prague or an Samsung S6 Edge is called zerolte
If you try to flash a firmware with another Region like C432 for Europa on a Device with C636 Asian Region...the verifying of the Update Package will not pass and update proceed will abort.
If you want to change the Region of the Device you need to use HWOTA Method for that...in the Script during configuration comes the Question to change firmware or to change location.
But be carefull by changing the Region cause the Devices for the different Regions could have different hardware integrate. Hardware like modem and so^^
OK thank you, i think modified firmware provided by 3c will work on my device as is has the same code of region c636 and the firmware flashed on my device is Asian pacific (c636)

Jfyi, the Huawei update server is down since February, so Firmware Finder is dead. Therefore, it is also not possible to use HwOTA or HuRupdater (unless someone has the necessary files stored on the disk).

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.

- 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.

Click to expand...
Click to collapse
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 ?
