Go to settings, about tablet and start tapping build number, eventually it will say you are a developer. Now in the settings menu you will see "developer options" tap that and scroll down to demo mode and turn it off.
See if that works.

Hi,
Thank you, but it is already on off...

Not sure then, if you do a Google search with Huawei and demo mode there are lots of suggestions.
Maybe try turning demo mode on, rebooting then turning it off to see if that has any effect. Otherwise I don't know.

Hi,
I have already search how to uninstall demo and even tried lot of stock rom.. but did not found a working solution..
If someone else have an idea...
Thanks

Just thinking out loud here for a second but I wonder it it may be hard coded in.. have you tried HiSuite to recover it? I would suggest that you that you could unlock the boot loader but from what I been able find /read there isn't a custom recovery for your model.. Have you tried downloading the correct firmware for you phone and reflashing it with Huawei Multi-tool as it has a repair/recover option in it and it works great with the M3.. you can get it over in the Honor 8 forum in there Kernel section.. also works for unlocking boot loaders flashing custom recoveries it a real handy program..

Hi,
Sorry to be late...but yes, I have already tested Hisuite...but I have a message that my Pad is not supported and have to send it to after sale service....
Thank for help

Hi,
A demo mode device should not be sold to customers. If you have the original box, the password for the demo should be on it. on the demo mode touch the brand logo than enter the password.
this is the only way you can remove the demo on Huawei.

Huawei P8 Lite questions

Hey guys, having some issues with my P8 lite which is recently purchased and is a great phone. I rooted it, and played around (as you do) installed busybox and played with apt-get and, well messed it up haha. Basicly I just want to unroot, stock reset the phone and start from scratch.
So, my question is.
Do I need to reinstall the firmware (ROM) in order to unroot?
And where can I get a stock fw for the P8 Lite ALE-L02, the original firmware to reflash? Can I flash the L21 on the L02?
Thanks

Same issue here
i think your only hope is reddit.com/r/Funkyhuawei.
I would like to share my experience how I successfully unbricked my Mate 9 Pro (LON-L29C636).
- My M9P was bricked. I've (Raygrobe) TWRP on it, but no OS.
- I tried every methods to flash the firmware but no luck.
- I downloaded C636 offline firmware (MHA-L26C636B110 firmware from Huawei Mate 9 Guides Forum and flash it from SDCard using 3 buttons method by Dload folder with success. My M9P changed to M9 with MHA model. It worked quite well, not much difference from M9P.
- I tried to rebrand to M9P using firmware for LON-L29C636 neither Dload or Firmware Finder method but no luck. The Firmware Finder struck on "Send to updater" menu.
- Someday later, I tried using "System Update" in settings menu. This time it asked if I want to change the model. After I accepted, it started to flash. Finally my M9P get back from brick stage to LON-L29C636B156.
Edit : Actually, in this case you may bring your M9P to Huawei Customer Service Center and ask them to reset your M9P and install the new firmware with no cost.

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

Google Services don't work - Huawei P9 Lite

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?
@faffolao @ITzAndry
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
