Build number : BalongC52B311
Emui version : 4.0
Android version : 6.0
Nothing seems to work, I can't two-step downgrade, installing stuck at 5%. Some custom ROMs for fixing Balong also stuck at 5% and I can't even switch to DUAL SIM, software failed.
Can anyone help me?

Flash B052 via Fastboot and install a vendor Update package for EU version

I have the same issue. I have looked here : http://consumer.huawei.com/at/mobile-phones/support/downloads/p8lite-at.htm but cannot find the B052. Do I need to flash the "Huawei_P8 Lite Dual SIM_Rollback package" ? And which .img do I need to flash? Do I need an unlocked bootloader and also root?
Thanks!!!

I resolved my problem thanks to this http://forum.xda-developers.com/p8lite/general/guide-debranding-converting-single-sim-t3305977. You need to open the bootloader first, but DON'T ROOT. Just open the bootloader. It's preferable to downgrade first (because you can lose your IMEI if you downgrade from 6.0 suddenly too much in one change). Here is the link for downgrading http://huaweifirmware.com/huawei-p8-lite or this http://forum.xda-developers.com/p8lite/general/rollback-official-android-6-0-beta-6-0-t3358565. Then you just follow the guide of the first link. Download C432B132, extract it, fastboot. Then you fix the balong bug. Now you have DUAL SIM without Balong. Then it's just about what Android version you want. You can stay on that firmware, OTA to newer a finally flash to Android 6.0. (If normal flash is not working, failed software update like it was with me, stuck at 5%, then use that fastboot with bootloader, I successfully installed new firmware with that method everytime)

Thanks. I will look at the second link you provided. First wait for the unlock code for the bootloader.

P9 Lite VNS-L31 - Can't upgrade to nougat after rollback

Hi all,
i own a p9 lite that was on Nougat VNS-L31C432B381 and i decided to rollback to MM. Following Huawei website instructions I downloaded two packages (rollback package and MM) and with 3 buttons method I flash first the rollback package and then MM. All went right and the ROM was stable. After a while of testing (that's why i went to MM), I decided to upgrade to nougat again. From updater it download and install the new android version (1.25 GB). After reboot I noticed that some system app was missing (file manager first). At every reset/factory reset some system app disappear. I repeated the procedure to rollback and upgrade again with the same result. The only way to use the device was to reflash MM and don't upgrade. Here some information I found:
- my starting version was Nougat VNS-L31C432B381
- now I'm on VNS-L31C432B160 (B160 isn't for dual sim? i have the single sim version) stock recovery bootloader locked
- updater try to install VNS-L31C432B370 (instead of B371?)
- if I try upgrade throught updater SN became something like ndr90 test key
- I tried to restore data,syste,vendor,oeminfo ecc.. from backups made with TWRP in Nougat (maybe wahile i was on MM, I'm not sure). It show the correct SN but ROM was still unstable
- I thought to try install full Nougat ROM but i didn't find any package
Can someone help me?
Thank you

The B37x update that the phone automatically finds after rollback doesn't work and will take you to ndr90 test key as you found out B160 is dualsim so you should flash the 161 one. Then use this guide to update through firmwarefinder/proxy https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-b388-nougat-maybe-b381-guide-t3612072
If you want to unlock your bootloader you can also flash B3xx through twrp. If not, the guide above works fine.

Hi Mara-X and thank you for you answer.
After I write the post i found the B161 package and i decided to give it a try. After flash (all ok) I launched updater again and it download the B371. The update went well and now i'm updating at B381 again throught updater. I think, when it was done, i'll factory reset the device for a clean install. So it seems the problem was B160/161 -single/dual version.

Serious problem installing stock firmware p10 lite

Hi everyone, I installed RR on my P10 lite (WAS-LX1A) and all used to work great except for the sound so I thought that the ROM was not good and I began to reinstall the backup of EMUI I did with TWRP but without success. So I searched online the stock firmware and I found several versions and I tried to install one using a guide and It seemed to work until I began the first configuration of the device. Every time I finish the configuration It resends me to the beginning and I cannot install other firmwares because they stuck on 5% or it gives me "Installation failed". I cannot install TWRP too because fastboot says "command not allowed" when I try to flash it even if my bootloader and Phone Finder are unlocked. Please help me.

I succeded in installing EMUI bit it's NRD90M test keys. I found online some guides that say to use twrp in order to flash the full update. But I cannot install any twrp because when I go in fastboot mode it says:
Bootloader unlock (red)
FRP Lock (green)

you need restore device with dcphoenix(paid method)

For any steps of fastboot, need frp unlock.

Hello, you can not do nothing if either FRP or bootloader are locked. You can either use DC Unlocker to unlock the FRP lock or DC Phoenix To Flash The Stock Image all over again... or you can take it to repair for mainboard replacement. I reccomend that you unlock frp and then extract the stock firmware using huawei update extractor. You can get the firmware by installing Firmware Finder On your pc and then searching for an appropriate firmware.

Thanks, I succeeded installing a stock firmware I found online but there's another problem now. Some stock apps are missing just like the file gestor and the updater in settings. If I go in phone information it gives me that my firmware is NRD90m test-keys. What should do I do?

try firmware updating with hisuite + huawei firmware finder's proxy

I tried but it's stopped at 5% of installation. I cannot do a update through the updater because it doesn't exist in this test version. Can I try something else?

I tried with hisuite and firmware finder using the proxy method but it can't find any update...

I think the firmware isn't compatible with your device. Try debranding.

Hi
My mate 8 is C636 Malaysia and I wanted to pass it in C432 Europe. changing the region with srktools does not work, that's why I had it all problem.
I install NXT-L09C636B563 FullOTA-MF-PV from Twrp and then I made an Ota update and now everything works fine and I have the latest version NXT-L09C636B598
Thanks

This was a nightmare. It took my almost 2 days to fix.
I had to unlock the bootloader, Huawei website gave the a code instantly so that wasn't the problem. The problem was finding the region firmware my phone started with (most links don't work anymore)
NXT-L09C636B596
I flashed it with SRK tool
Fastboot flash boot boot.img
Fastboot flash recovery recovery.img
Fastboot flash system system.img
Fastboot flash cust cust.img
(cust.img was located in a seperate download called update_full_NXT-L09_hw_spcseas.zip
Had to use Huawei update extractor and get the cust.img from within update.app
Even still I had nrd90m test keys, and the problem was I had no update menu in settings. Keyboard and so on didn't work. I had to use the Google search bar to voice type keyboard APK and install one from a site.
But I'm not sure how I got the update setting again, if you don't have it also. My developer options wouldn't work either
Somehow it appeared (not sure if it was because I wiped in twrp or something)
Anyway
I downloaded firmware finder and downloaded
NXT-L09C636B598A full ota-MF
Downloaded it, it wouldn't verify, so I restarted the phone and used my mobile internet and it installed
Everything is good now

Hi
why change region? what is the advantage, the interest?
I have a version C636 Malaysia and I am in France is all working very well, so why different regions?

Hy Ango can you help me, i have the same pb like you and i can't resolve it !
I am from France and i want to fixe it
i am waiting for your advice
thank you

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
Cheers

Unpack downloaded .zip package, you will see two files - ReleaseDoc and Software. Open "Software" and unpack SDUpdate_Package.tar.gaz. Transfer file dload to SD card and follow instructions - there is 'Software upgrade guidline' in file ReleaseDoc.
Edit.:
You can also safely lock BL with OEMINFO flashing and rollback to A6:
-Download OEMINFO:

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66015/f1/full/update.zip
Create a folder dload on your SD , unpack downloaded .zip file and copy it to the dload folder.
Install TWRP 3.1.0-2:
https://mega.nz/#!EsESQQhK!uc_lfXEfDW6U7Lq2VeNOYq5OWUID0G-YyhK-oUL4deU
