Hi,
I simply cant reach step 4. When I try to launch the UPDATE.APK, my mobile restart to TWRP and nothing happen. I guess it is because the TWRP is here? Is there a way to unistall it? Or Is there an other way to launch that UPDATE.APK?
Thx a lot for any help.

I guess I need to flash stock recovery? Anyone has stock recovery download link, which can be used for B511?

Yeeeeah... The ultimate, simple and easy to follow guide! Just 2 files to mess with and you are good to go. Worked great on the first try. For the others, you have to be using stock recovery and it is preferred not to be rooted.
Thanks!

Someone has tested for TL10? It works?

If you are in b500 indeed you are ready to downgrade with a lollipop stock rom. Use the same steps but with the LL rom

I'm on B500 too, but I'm unable to downgrade or even upgrade to other version. Maybe I don't have right version, so could you please tell me which version to use? When I tried to downgrade to B329 (official from Huawei site), updater goes to 5%, than I get error: "Software install failed!".
Please, help me out and thanks!

Try b331

Thanks for the guide, however, I couldn't get it to work on my UK H7. I'm already on B180 with no root and bootloader still locked so I just proceeded from step 9. I placed the UPDATE.APP from the update.zip I downloaded to the dload folder but it fails (like you said) but when i reboot i'm still on B180.
I also tried just placing the update.zip directly into dload but that also fails after attempting a local update.
Any ideas?

Hi Andy
I think it maybe because you are not rooted or you may have done something different.
Try downloading the files again.
If not follow this official guide if you are not rooted http://www.modaco.com/forums/topic/377073-how-to-update-your-honor-7-to-marshmallow/

I backed up, just in case.
I tried again, the update went really quick (like 15 seconds) then said it was complete and I restarted. Since then it has been sat with the honor boot up logo for about 10 minutes... I'm just going to wait and hopefully it will boot into the android system
EDIT: So it's not progressing from the boot logo... I went into the recovery and wiped/factory reset to see if that would help but it's just sat at the boot logo again and won't go any further
I can obviously get to recovery and to the update screen so I'll have to try and download the full B121 ROM and put it on my SD card to try again.

Are you running custom recovery or stock?
If you are on stock recovery Start a fresh install
download the full B121 firmware flash it and after setup you should get OTA update notification proceed with the update once the update it done to b180 download the full firmware for marshmallow from here http://www.hihonor.com/uk/support/details/?DOC_ID=77509
Extract the zip file once done you will see a dload folder copy the UPDATE.APP to you dload folder in your sd card then go to settings and update click on local update and update the phone.
Let me know if it worked.

Yes, full stock. Never rooted or unlocked bootloader. I agree, I think the full 121 upgrade path is probably the best option now, I'm in the process of copying over the update.app from the 121 firmware to my sd card as we speak. I tried the 330 update while I was at work and didn't have my usb sd card reader so I've only just managed to get home and start that now.
EDIT: I'm just getting the update failed message now when attempting to install the B121 Update.App... about 6% into the update, then just asks to reboot system which gets stuck at the boot logo again :/
EDIT 2: After repeatedly trying and switching between B100, B120 and B330 update.App files to try and reflash the firmware the B330 version finally decided to do a full install and complete 100%. Very strange how it literally just decided to work this time but all's well that ends well I guess. If anyone else has this issue then just persevere and keep trying, hopefully it will just work one time!
Thanks Tile and Alphadude for trying to figure it out

for unrooted B180 this is how i did it
I went from B180>B320>B330
downloaded B320 to sd card
extracted intermediate file to sdcard/dload
EMUI update app and manual update
it restarted and did its buisness
deleted the UPDATE.APP from dload folder and copied in the full UPDATE.APP
EMUI update app and manual update
it restarted and did its buisness
then once restarted back into the emui update app and it said the 330 update was available OTA
no data loss through any of it

Make sure you flash the intermediate file first and then the main update

I doff my cap. It worked. An error at 95%, plodded on through and I'm now on MM B330.

Good work. I've noticed an improved battery life on b330

There's nothing great that I've come across yet. No data lost either doing the upgrade so I'm happy to be on MM.

After the update everything else seems to be working fine and smooth, but i've had several sudden restarts and couple of freezes.

Updater missing from settings

Hello, today i have decided to update to nougat so i have downloaded and installed CAN-L01C150B330 from firmware search, when i go to settings the updater tab is missing, if i search updater on setting, updater is show but i can`t open it....so i have tried to do a factory reset, phone boot into recovery stared factory reset but stopped at 5%.
I am the only one with the missing updater and the factory reset error?

Here are the steps fallowed to install nougat:
- unlock bootloader
- download the firmware
- extract update.app and copy to dload folder in the root of sd card
- extract recovery.img from update.app with huawei extract tool
- flash extracted recovery.img with fastboot

how did you install?? i have tried to install as instructed but update failed

make it like Jozinek has written in this thread (https://forum.xda-developers.com/nova-plus/how-to/c432b320-android-7-0-available-try-t3527084)
only i have the eu update package just as extracted and installed as the full package.
1. download both zip files
2. extract the full update zip and put the UPDATE.APP file in the dload directory on the root of your sd card
3. force updating by (poweroff your phone and) holding all three buttons on right side together
4. wait until the update is complete
5. extract the eu update zip and put the UPDATE.APP file in the dload directory on the root of your sd card
6. force updating by (poweroff your phone and) holding all three buttons on right side together
7. you have it (i hope so )

Still i am not able to install the eu pack, uptade stops at 52%.

i dont know, if anything is wrong with your unlocked bootloader combined with the update package. that is the only idea i have.

[SOLVED] Need help to upgrade from L31-C900B151 to latest Nougat build

SOLVED: please check my 2nd post.
Hello guys,
I would like to upgrade my P9 Lite L31 from M to N official. I've tried the past few days but it always ends up with "NRD90M test-keys" on build number and missing apps. I have read A LOT of threads/posts about this issue, really everywhere, but I can't figure out how to update my device without problem.
Also I do know there are some Q&A threads/GUIDES/HOW-TOs in the forum but I don't find the right procedure for my case.
I assume it's because I've flashed the wrong package or forgot something in the procedure...
I've followed this GUIDE by @simo255: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932
Here is my info:
P9 Lite VNS-L31
3 Gb RAM
Build: VNS-L31C900B151
EMUI 4.1.1
So, I'm on C900B151 and I'd like now to upgrade to C432B380 (or C432B381 ?) (or above if available).
If I understand well, the correct procedure is:
1- unroot (necessary?)
2- change from C900 to C432, by flashing an C432 OEMINFO.img through Meticulus TWRP (v4)
3- flash the latest Nougat update.zip package (B370/B371 or B380/B381) through Meticulus TWRP (v4)
4- flash the latest data full EU zip (B370/B371 or B380/B381)
5- reboot
Is it OK?
At steps 3 and 4, do I have to get UPDATE.app for B3xx and use the dload method instead?
FYI, I didn't follow step 2 when I tried, is it the culprit of my CUST errors in TWRP/"NRD90M test-keys"/missing apps problems? Or is it because I've flashed B370 instead of B371?
A few questions:
1- Is it a problem to currently run B151 firmware for my L31 for the Nougat upgrade process? I've read that the last digit means dual SIM or single SIM. I think I have a single SIM version but I'm not sure... How to know for sure? Sorry for the dumb question
2- If I don't follow the procedure above but if I relock my BL and then check for updates, do you think I will get a Nougat full OTA for C900 (C900B151 > C900B3xx)? Is it really necessary for me to change from C900 to C432?
3- In any cases, would it be possible to upgrade directly from B151 to B38x? Or do I have to go through B16x or B37x?
4- I can't figure out how to get the correct full OTA for Nougat, the one bigger than 1,9 Gb. I always get 1,25 Gb package through OTA update in settings, even when I'm running C432B160...
5- Is it possible to use Firmware Finder to update from B151 directly to B38x (or above)?
I already tried to flash a B370 update.zip and data full EU (from this GUIDE) but I have error about CUST in TWRP and as already said, then I get "NRD90M test-keys" on build number and missing apps after reboot.
After this, I successfully downgraded to C432B160 (maybe it would be better to downgrade to B161?) and I get the B370 OTA (1,25 Gb), but as you know it's not the FULL OTA... So AGAIN: "NRD90M test-keys" on build number and missing apps.
Sorry for the long post but I find really hard to flash/update stuff on this P9 Lite. I'm really confused. I was before on a Samsung S3 LTE and it was easier...
Any advices?
Thanks in advance.

I solved my problem!
My mistake was to install build VNS-L31C432B160 instead of VNS-L31C432B161, that's why OTA available was not the correct one (1,25 Gb instead of 1,99 Gb)
B160, B370, B380 are for dual SIM
B161, B371, B381 are for single SIM
I have a P9 Lite L31 SINGLE SIM
I was on previously on build VNS-L31C900B151 and I'm now running build VNS-L31C432B381 official and everything is working well.
The steps:
1- Download Update.zip of VNS-L31C432B161 (size around 1.6+ GB) (I've found it and downloaded it with Firmware Finder)
2- Extract the UPDATE.APP of the ZIP with 7-zip or similar and copy it on External SDCARD in a dload folder
2- Make sure to be rooted (Bootloader unlocked, TWRP v4 by Meticulus installed and SuperSU flashed)
3- Flash OEMinfo.img and custom.bin for C432 Single SIM (download link: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873, from this thread: https://drive.google.com/drive/folders/0B3CRCPqinridRXNPdDNuM2g5dTA) with Toolkit (download link: https://forum.xda-developers.com/devdb/project/?id=16538#downloads from this thread: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873)
4- Reboot > It asks for decryption key (I entered a wrong one because I didn't even know the code) > it fails to decrypt and then ask for factory reset
5- Factory reset fails (I don't know why)
6- Reboot on Android > build is now VNS-L31C432B151 (it changed from C900 to C432 thanks to the OEMinfo.img and custom.bin)
7- Shutdown the phone
8- Start the phone with 3 buttons method: vol- ; vol+ ; power

So i have the same problem.
I've the L21 Dual sim model (2GB) and i tried to update.
Messed up with firmware finder and ended up with a wrong update. I've managed to get back to L21C432B160.
What version do I pick with Firmware finder? Or do i need to flash another OEMinfo.img en custom.bin first to get an update?
I don't want to end up with beta firmware or something messed up so I keep getting future updates. I don't understand why the OTA update is still here on my p9.

Which oeminfo.img and custom.bin did you flash lately? Is it your own files or from someone else?
And you say you are currently running L21C432B160 but which OTA version is showing up now in ROM settings? Which size?

Haven’t flash any of these files yet. I dont have an ota in upater right now. That is The probleem. Only with the firmware Finder i can get updates but i dont know which i should pick

If you want to get OTA updates, you need to have your bootloader locked. Is your bootloader currently unlocked?

Yes. But the problem also occured when it was locked.

Update for Huawei P9 Lite 2016 Dual Sim (VNS-L31C900B114 to VNS-L31C432B160 firmware)
Wood Man said:
I solved my problem!
My mistake was to install build VNS-L31C432B160 instead of VNS-L31C432B161, that's why OTA available was not the correct one (1,25 Gb instead of 1,99 Gb)
B160, B370, B380 are for dual SIM
B161, B371, B381 are for single SIM
I have a P9 Lite L31 SINGLE SIM
I was on previously on build VNS-L31C900B151 and I'm now running build VNS-L31C432B381 official and everything is working well.
The steps:
1- Download Update.zip of VNS-L31C432B161 (size around 1.6+ GB) (I've found it and downloaded it with Firmware Finder)
2- Extract the UPDATE.APP of the ZIP with 7-zip or similar and copy it on External SDCARD in a dload folder
2- Make sure to be rooted (Bootloader unlocked, TWRP v4 by Meticulus installed and SuperSU flashed)
3- Flash OEMinfo.img and custom.bin for C432 Single SIM (download link: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873, from this thread: https://drive.google.com/drive/folders/0B3CRCPqinridRXNPdDNuM2g5dTA) with Toolkit (download link: https://forum.xda-developers.com/devdb/project/?id=16538#downloads from this thread: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873)
4- Reboot > It asks for decryption key (I entered a wrong one because I didn't even know the code) > it fails to decrypt and then ask for factory reset
5- Factory reset fails (I don't know why)
6- Reboot on Android > build is now VNS-L31C432B151 (it changed from C900 to C432 thanks to the OEMinfo.img and custom.bin)
7- Shutdown the phone
8- Start the phone with 3 buttons method: vol- ; vol+ ; power
9- Wait a few minutes L31C432B161 to be installed > It reboots and you're now running L31C432B161
10- Search for OTA in ROM settings > You will get L31C432B371 > Download and apply the update
11- Wait a few minutes L31C432B371 to be installed > It reboots and you're now running L31C432B371

I meant once you run full working Android 6, you have to go in Android settings, in a menu called something like "system updates" or similar and you should see if a newer Android version is available, meaning Android 7.
I'm running Android 7.0, so I can't show you screenshots from Android 6,sorry... Here are 2 screenshots from EMUI 5.0 (Android 7) in case it could help.

P9 lite No audio After TWRP restore Dload failing HELP

[SOLVED] Hi i was on l-31c432b381 firmware with emui 5.0 and android 7.0, i have unlocked the bootloader for install magisk 12.0 and have root permissions, after months i saw an update for my phone (b389) so i tried to upgrade but i had twrp so error 1 or 7, i flashed the stock recovery, redowload the update and the install failed at 5%, so i tried to unistall magisk before update, but nothing it wont update, after few tries the upgrader says that the update now is not 300mb but is full and is 2gigs, so i think is the time.. but no. so i tried to force the update with 3 buttons recovery dload method but it doesn't work at all 5% at every try. so i searched for support and i found that the ota connot be installed on unlocked devices, so i tried to relock my bootloader with oem relock and the unlock number but it says root type is risk... so i can't even relock my bootloader.. other says that i have to install to relock or can relock... but is b381 the stock? or they instend the mm version? i don't remember what version p9 lite ships. i tried to flash imgs through fastboot but even if i flash system and boot of the b389 the system boot and the info are of the b381, unisatlling app system crash, so i restored my previous backup made through twrp recovery, i immidiatly noticed that the huawei boot animations was gone and was an android stock animation. i thinked it was fine and all was working properly, i give up o upgrade and i was fine but sad. after few hours i tried to make a paper copy with my printer that have nfc but my phone keep shows and hide nfc symbol like on off on off on off over and over even after reboot, after a call i understand that the audio doesn't was working, every type of audio not work even the mic. i don't see any other problems but without sounds is unusable as a phone or mulimedia things... sorry for bad english please HELP i tried all i founded ...

Hi, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!
Download official rollback package for your VNS-L31C432
http://download-c1.huawei.com/download/downloadCenter?downloadId=93789&version=373429&siteCode=sk
and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

Yes, you can. Via OTA, or you can use TWRP (Meticulus 3.0.2.0 only ! ) and flash both .zip files. You must download two files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v80474/f1/full/update.zip
and
http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_VNS-L11_hw_eu.zip.
In TWRP set Install, then select memmory SD card, and klick on
update.zip, confirm installation. After, STAY in TWRP, go back to Install, find file ...hw_eu....zip , confirm installation. Then select rebot system. Done!

Try it, but I think, you will get a message "not compatible" . Via dload its impossible, IMO use rather Huawei firmware finder or wait for OTA update.

If I said, it's impossible manually update to 381 or 389 using OTA firmware, trust me . Try Firmware finder. GL!

i'm now back at b381 with sound but without my data, i'm trying to reach b389 and over, can i restore through twrp only data partition without a hitch?
in b389 emui is 5.0.1 if i remember right. its data compatible? are the data the cause of no sound? thanks

FF works with proxy fine, but you must first download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.
