the new one as in TWRP 2.8.6.0?
which version of ICS did you install B928?
if so did you:
check if baseband 404029 instead of 404020?
IMEI wasn't messed up during process?
follow pink screen unlock method?
where does it say image signature verify fail during which process?

I am not able boot the phone its....neither to recover or normal mode...the baseband was 404029..I think

If you were on B928 version, you can run pink screen unlock to install a custom recovery such as TWRP.
However if you're not able to boot, this possibly means you flashed a wrong firmware. double check if you have a u8800pro not the u8800 or u8800+ (i'm not sure about the + one) they have different firmware.
Overall if you have a u8800pro, i recommend installing the stock B928 following the official procedure, this is almost a foolproof method to fix any possible software issue you may have.
the link below should have all you need.

Solved the problem
The answer was so simple....If u want all the data present in your mobile download the boot loader unlocker from the website given above by sarsiroslayer..thx man
Paste the Update.App in folder called dload and the folder should be in the root of the sdcard...yes you need a sdcard...and then remove the battery of the phone so it switches off...then connect the phone to the USB wire without battery...and immediatly press the volume. Down,volume up and power button...so it goes to a pink screen..and remember the sdcard should already be placed in the phone...and yes if the phone does not go into pink screen and instead starts to update the software Olla ur phone is fixed......restart and all will be fine...
Ifthis did not work or u don't want any data download the official 2.3.5 android from the huawei site and place the update.app in dload folder and do the same thing as above....My phone is working..:highfive:
Remember remove the battery...before updating ....
Thx all for ur support..xda rocks...
I have typed the solution so even a begginer can utjnderstand...

Please help!!!

Hi!
I haved flashed B329 on my Huawei P9 lite.
Then I got problems and flashed back (after spending much time) to B151.
Then offical Huawei update to B161 was there. I tried to update but got error message.
Then I tried to update manualy to B161 and several other firmwares like B329, B336 and during this I have done something wrong. Now I am trying since 4 days, to install any firmware that will work again.
I have done many things in this time. I don`t know anymore which status is present on my phone.
I can start fastboot rescue modus and I can run Meticulus Recovery and Revolution Recovery. But I can`t flash any firmware there. Always get message that something failed. DLoad Modus I can reach, but any firmware I put in dload on my external sdcard didn`t work. After 5% I get message that it failed to update. I don`t know what I can do anymore. I think I have done something stupid with my partitions and many more. Now I am totally frustrated and don`t know what to do, to become my phone running any firmware. So it would be really really nice, if someone of you could help me!
Thank you and sorry for bad English!

Hi again!
I have tried a thousand of things and finally I have become it running again
If someone else did have this problem...
I have uploaded an package that contains all that was needed, to become it booting again.
(OEM Patch, recovery and download link for stock firmware from this forum)
Sorry that I upload these files without complete information where they come from. I don`t know anymore, because I downloaded and tried too much things to become it running again. If someone knows where these files are from, it would be great if this information could be updated.
Hope that I can help other users that have this problem, with this package, to fix the problem.
This I have done:
1. I have flashed recovery using fastboot
2. In recovery I installed the zip containing OEM Patch
3. I started recovery using dload method (must not flash any other recovery to start it)
If Bootloader is locked... I have used "SRKToolHuawei-Lod-Chong-V2.0-20161002" to unlock it.
Greetings and sorry again for bad English,

Huawei P9 lite VNS-L21 can't load stock rom and all standard apps are missing.

My question is this....
How do I revert back to a stock standard P9 lite? I tried to root my Phone (My own stupidity) and now my phone has all the standard apps missing.
I've tried flashing through twrp and sd card. nothing works. I've rooted the phone eventually, but I have no way of reverting back to stock standard.
I've even tried rollback, but the phone doesn't want to install the rom.
Can somebody please help me....

I realised that the phone was bought in Dubai. I flashed the first flash file and it updated.... (HUAWEI P9 Lite Rollback Package 8VNS-L212C from EMUI5.02BAndroid7.0 rollback to EMUI4.1BAndroid 6.0C C185B300C Middle EastAfricaC 05014GRY.zip)
I'm waiting for the second package to finish downloading, but willl tell you if it works.
I have been flashing the wrong firmwares this whole time and have been struggling since saturday morning.
Thank you for the reply.
P.S. They should tell you that you need area specific firmware.
Update: I finally got the phone rolled back to Marshmallow and it updated back to nougat from there.
The only thing I did wrong that I can see is that I didn't have the knowledge. If I knew from the start that it had to be area specific, then I would have been done on Saturday instead of yesterday.

Hey man,
there is no problem for the PM but it's always better to create (if not asked yet)
or post help requests on an existing thread ...
This way everyone can see that you need.
Or use @ to quote someone and call them back the attention ...
As I have already written in other posts I do not have anymore the P9 lite as I sold it.
Soon I will not even have the P10 lite anymore and I will not attend often this thread ...
Let's see now what can be done, it seems almost a desperate case ....
Unfortunately, the magic wand does not work and I can not do magic so you have to help me.
Which version of TWRP did you use?
Are you 100% sure that the android version was NOUGAT when you tried to root the device?
In which region of the world do you live? (serves for the regional version of the firmware),
but I think you could also use other versions (by rebranding) ...
Single or dual sim?
Can you access the system?
Boots in TWRP?
Does fastboot / bootloader mode work?
Dear answer these questions and "maybe" with a few days
we can bring it back to life .... I said maybe ...
Regards

Stuck on NRD90M test-keys

Team,
I've got a problem. My brother got the phone locked on NRD90M test-keys and can't roll back. I've tried getting into the SD card the UDPATE.APP for my model (VNS-L22) but when doing the three key method it shows an error message with something like "incompatibility with current software" and it just gives me the option to reboot the device. I have access to the device as it boots but things like camera stopped working (it's been a while since he did that and he just told me)
I've tried with the "Huawei Recovery Updater thread" here but I don't know if I am doing something wrong or what but it does not work.
Reading a bit more it seems I've to unlock bootloader and do a bunch of things, just wondering what do you think is the best approach or how can I get back to stock ROM, so we he can get OTA updates and have the device working without a problem.
He did this by using the Firmware Finder app from play store, so I guess he did an update and got the device on that state.
Device details:
EMUI Version: 5.0
Android Version: 7.0
Huawei P9 lite
Model: Huawei VNS-L22
I appreciate all the help you could provide,
Thanks!

Hello,
if you remember exactly the complete firmware your device were on
before been stucked on NRD90M test-keys, maybe using Firmware Finder ( FF )
you'll be able to force the update to a newer and working version..
( ex. mine was VNS-L31C432B381 and updated to B415 )
The other method is most complicated...
Unlock the bootloader, flash a custom recovery and use
Huawei Recovery Updater in order to reflash your stock rom.
Then you should use FF too to make an update and correctly
relock the bootloader.
Is you'll use those awesome apps don't forget to thank the developers.
Cheers

Yes I do, actually I just realized the one I could find here wasn't the same I had before so maybe I will try that one. I tried firmware finder from the app but it wasn't working properly, when downloading the FULL OTA files it started crashing and then I was not able to proceed with the "downgrade" now i've used the FF for PC and downloaded the files from FULL OTA, however there are 3 files. I am not sure what to put into the dload folder.
These are the files:
update.zip
update_data_full_hw_normal.zip
update_data_full_ice_cr.zip
As per my understanding I should place only the files from "update.zip" right? I also saw a few comments on a video that said put all content from all three files into the dload folder.
If you happen to know the answer I will appreciate it!

Hello,
I'm also stuck in this rom... But in my case I went from a custom ROM to it. But it blocked my bootloader, etc...
And I forgot my bootloader code
Now I have to unlock it and I will use DC-Unlocked but when I dial this number: *#*#2846579#*#* in this ROM it doesn't show anything!!! So I can't open Project Menu...
What can I do?
Thanks

Dude,
you cannot use DLOAD aka three buttons method
on nougat ( android 7 ) 'cause it wont work.
As i wrote you should know exactly the firmware your device were before the softbrick.
Getting 'nrd90m - test keys' firmware probably mean you already tried to use a wrong firmware.
I don't know whic firmware you downloaded, but i can assure you without that correct no methods will work.
As you can see in the attachment exists many custs ( C185, C569. C576, C635, C636, etc... )
and firmware ( Bxxx ) that indicate the region/brand were you live or where the device was sold when you bought it and if single or dual sim.
Without those info become a lot complicated bring back your device in an working state.
The last chance should be a rebrand but you need some files like OEMinfo zip but ever first you should unlock the bootloader, flash a custom recovery and use HWOTA method, but the risk
to completely brick the device is really high.
Example of a firmware : VNS-L31C432B415
VNS ( venus is the name of the device )
L31 ( is the version of the device )
C432 ( is the cust that indicate the region where was sold )
B415 ( is the running firmware/security patch on the device )
You had VNS-L22 C??? B???

Dude,
before attempting to unlock again the bootloader
you should try to force the update with Firmware Finder.
What was the firmware you were on before flashing your custom rom ?
Which custom firmware you were on ?
How you gone back to stock ?
Which stock firmware you used to go stock ?

So the firmware I had before doing that was VNS-L22C106B150.
What should I do with that if the android app is not working? I mean... I tried doing it with firmware finder and it didn't work, used proxy thing, dns thing, downloaded the files (multiple errors, files corrupted) and it is not my internet connection, it's the app. I did downloaded the files on the Windows app

Ok, if you sure your firmware are L22C106, things aren't so good.
Cannot make an update, can make a downgrade but you need the correct rollback package
and i don't know were you can find it, but in any case you couldn't re-upgrade to android 7.
Checking in the FF PC 's app, as you can see, no nougat
versions of this firmware are present. Which version you downloaded before ?
If you are really sure about that firmware, you have only a possibility, which is
make a rebrand but it's a bit complicated and really dangerous.
Choise remain yours, you can find some guides how to do a rebrand, just search
in the p9 lite threads.
Cheers
