Updating stock emui ROM on a rooted P9 lite - Huawei P9 Lite Questions & Answers

Hello everybody,I have a question :
My P9 Lite (VNS-L31 C432B380)is asking me for B388 update.
I rooted my phone using OldDroid's TWRP 3.1.1-1,and official TWRP.
I know i need the stock recovery to be able to install update from settings.So,i googled a bit,and impossible to find the B380 firmware (my Idea was to extract the recovery from it using Huawei extractor).Then i remembered Firmware finder,and I looked for the B380 inside the App.There I see 2 entries for B380,OTA-MF (290MB) and FULL-OTA-MF (1,6GB).
From which one Can i extract the stock recovery safely with Huawei extractor ?
Thanks in advance !
P.S : if there's others ways to update than unrooting,reflashing stock recovery,installing update and then reroot,please tell me !

The way I did it is by downloading the FULL update (it's 2go) an update extractor(found in this forum) extracting the recovery from the update app... Flashing it using adb... Updating normally (make a save of the 2go update and remember the directory just in case to avoid having to dl it again) the reflash twrp and root!!

The biggest package I can found on FF is 1.601GB where did you find your 2Go one ?
EDIT : downloading the fullOTA-mf package gave me a 2.51GB update.app file. update extractor sees recovery.img and recovery2.img,which one do I have to take ?

DESCRIPTION:
Hey Guyz Welcome Again in my next Tutorial... Today Am gonna show How to Upgrade/Update your HONOR 4C to Android 6.0 Marshmallow.
If your Gonna Step in to Marshmallow from Kitkat or Lollipop, didnot Mattar Both process take same time.....
Lets move on it...
PREREQUISITES:
First of All you should have the files needed for that....
1) Indian B330 ROM Lollipop
2) Indian B370 Update OTA zip
3) Indian B510 Marshmallow OTA zip
4) Indian B521 OTA update zip
Links for these files.....
[UPDATED]Indian B330 ROM Lollipop and decryption Key is !ldp5f_t_y7JaPIjCRugiYuS3QOHezIWgQoC2RwCCjrc
Indian B370 Update in form of zip file
Indian B510 ROM Marshmallow update in zip form
B521 from B510 Marshmallow OTA zip update
In Case you have B390 build, flash this zip directly to get B521 ROM Marshmallow
B390 to B521 Marshmallow update direct
PROCEDURE:
Now First thing is if you dont have the indian ROM,,, i have the guide to Flash any ROM on your 4C even of different Regions....
Here is the Link for that Thread!! Guide to Flash Any ROM
You just have to flash the first ROM which is of G-Play Mini's ROM but dont worry....its the solution for everything for 4C...
Now Extract the B330 lollipop ROM, you will have the update.app file of about 2.5GB...
Backup your all data first,,, It may wipe your all data.... dont blame me then...
If you are on currently B390 or any other Build, Flash directly by Putting this update.app in dload folder and then put dload folder in Root of your SD Card...now go to Settings>Updater and then press Menu and then Local Update... you will find the pkg here... just install it...
Now Flash the Vendor pkg present in same folder of B330 if you are converting to indian ROM... flash vendor's update.app in same way as you flash update.app of B330 ROM...
Now you should have B330 installed successfully... and you should have Build number CHM-U01C636B330 otherwise you're gonna get error of 5%
Now Rename the B370 update zip to update.zip and put it in dload folder in root of your sd card..
Now go to updater and then local update... And install update too same as before!!, it will install that update.zip of B370 ROM..
Now you have B370 installed....
Now times to flash the B510 Marshmallow ROM.... rename Marshmallow file to update.zip file and then do the same procedure we do for installing B370 ROM...
Now flash the Patch for B510 by HassanMirza01.zip file attached below using twrp recovery (Link and method for TWRP) and you will have the option of local update in B510... then flash B521 using local update method.
Then do same for B521 update like we do with B510.... after successfully flashing... Phone will booted again and BOOM!!
Latest Marshmallow now installed
Also Here is the Link for Full Marshmallow Rom in case above MM file stuck or whatever, Link for Full Marshmallow ROM B510
Flash it on B370 or G Play mini ROM, it will install whole Marshmallow ROM.
For any question, ask below.....
In Case you dont like this Rom, and you wanna downgrade to Lollipop again, here is the Link for Lollipop Rom
Download it, unzip it, put dload folder in root of sdcard. Now MM dont have local update option so dial code *#*#2846579#*#* in MM Rom, you will see software upgrade option there... Press it and your done
Hit Thanks and Support me if you Like and get help from this thread...Thank you...

[Q] Stuck in rescue mode

Hey guys,
I have a huawei P8 gra-l09 v100r001c576b161
I tried to TRWP it and something went wrong.
I get:
Error!
Func NO : 10 (boot image)
Error NO : 2 (load failed!)
Any help would be appreciated!
C576 would indicate an Israel region firmware.
Did you unlock the bootloader before attempting to install TWRP? What version of TWRP did you use? Where did you download it from?
Similar problem HERE (P8 Lite), which was solved by the op by flashing the original(?) firmware - view posts #6 & #13.
Download link here for C576B161 (download the correct one & only use a C576 build for this - not what the op used as his was meant for a different phone & region): http://huaweidevices.ru/category/huawei-p8-gra-l09. Once downloaded, unzip to Update.app.
If that doesn't work, try solution in post #16 of above thread - i.e. flashing those individual files one at a time after extracting them using Huawei Extractor. Then rebooting, & finally flashing the Update.app file only. Use same firmware file you downloaded above.
If above doesn't work either, try similar solution here: [GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop. I couldn't find a firmware just previous to your B161 (as required there), so you'll need to make do with B161.
---------------------------------
Btw, if you cannot get TWRP to install & work correctly, you may first need to update to Marshmallow (Android v6) - you currently have Lollipop (Android v5). If there is no Marshmallow update for your region's version, it might be possible to change to a European rom (C432), which receives regular updates. Then, if successful, you can follow this guide to install TWRP: [Guide][Huawei P8] TWRP + Root Systemless Marshmallow Installation (GRA-L09 & GRA-UL00)
Thank you very much! You saved me!
Hopefully now I will be able to be careful and upgrade to Marshmallow!

Hi,
1) wipe Dalvik & cache, flash stock recovery of b370, and then do like you wanna update to b380 using firmware finder, (use the big file)
or
2) rollback to MM : flash oeminfo for your location (recommended) , flash Rollback Package via dload , and then flash stock B160 via dload.
or
3) remove root from SuperSu app, then use Rocatex uninstaller

P9 lite vns-l31 update from b 360 to b392 help needed

I have already unlocked and rooted my vns-l31, installed c185b360 also installed revolution recovery
I received an OTA update through system update B392
I downloaded it through system update
It's 3 zip files in Hwouc folder in sd card:
Update.zip
Update_data_full_public.zip
Update_full_vns-l31_hw_meafnaf.zip
What should I do?
It enters revolution recovery and it doesn't install the image and returns error
Should I try 3button method? And how to flash all the 3 zip files
Help me please
Thanks
Hello @thefarhad,
sorry if i write this but "it seems" you already know what you should do,
also it does not seem possible that update has arrived that way,
i mean official updates automatically installs..
It seems instead that you have downloaded it with Firmware Finder (full OTA-MF), isn't it ?
(If i'm wrong please just not consider this post...)
Now try to follow guide "how to update" you find here on XDA.. (use search, there is more than one).
My little suggestion: proceed by little steps like installing B380 first, then check if official one arrive, if not install B392 with FF.
P.S.: Read threads more than one time before doing anything, just in case something could escape you... only a friendly suggestion..
Regards

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

Piece.
Hello,
I reinstalled the custom rom that I found on the net: C432B414 with Hurupdater.
It works.
However, the bootloader is still unlocked ... however, I would like to return to the factory configuration with the bootloader locked.

I have the stock recovery install :
https://www.cjoint.com/c/JItg7SqQmdB
I am currently downloading the file indicated by this link : https://androidhost.ru/41d

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:
https://mega.nz/#!xhEwFYLZ!Sv2nB5GERB_js76sAUWxj8hQgsjnf_YPobVbtrxpCew
Transfer it to the SD Card.

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
using command
fastboot flash recovery2 twrp.img (OVER eRECOVERY!) , boot in TWRP, fĺash oeminfo.zip , go back to TWRP's main menu, select Reboot and Power Off. Then use three button combo and flash firmware from dload. Your phone will running A6 with locked bontloader. If you want, you can upgrade back to A7 via OTA update or using Fipmware finder.
