my old build l21-c185b160
i upgrade l21-c185b525
now i want to downgrade l21-c185b160
how to do this. please help me.
You must have your c185b160 update.app file, you'll also need Huawei Update Extractor download link : http://forum.xda-developers.com/attachment.php?attachmentid=3262544
And minimal fastboot, link:http://forum.xda-developers.com/showthread.php?t=2317790
Now unzip the downloades extractor zip file amd install it.. Open the extractor and browse update.app (b160 update.app). After browsing, you will see many files; image files (system.img, boot.img,etc) amd other files (meta-inf, etc).. Among them you'll need only 4 image file; system, boot, recovery and cust..
Unzip minimal adb and fastboot and install it.. Now open it with administrator privilege and flash in this order:
Fastboot flash boot boot. img,
Fastboot flash recovery recovery.img, Fastboot flash cust cust.img,
Fastboot flash system system.img..
If flashing is done, you're on b160

Device: VNS-L21 Europe Hello, before brick I was on new emui 5.0 firmware and I installed nougat twrp recovery by user @BadWolfYe and then I flashed this rom: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493 (I was following all instructions) After reboot It was stuck on Phone is booting...

2. connect phone to computer
3. open cmd and type: fastboot -i 0x0fce oem unlock xxxxxxxx (replace xxx with your code)
4. accept fastboot unlock
5. And then it magicaly booted into twrp (my phone's fastboot was unlocked before)
Now I am going to flash back emui 5.0
And then downgrade to emui 4.1

hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM. IDK what happened wrong while installing that, my phone got BRICKED. i don't have the Erecovery and twrp either. i cant flash firmware via DLOAD Method. the only thing i have is FASTBOOT mode..

Hi, I need help, I have the Chinesse version of mate 8( NTX AL10), and I installed the 577 version in HiCare, but Im having too many problems and I want to rollback to Android 6.
Someone can show me the way? I tried to install twrp recovery (I have the bootloader unlocked), and I couldnt format data because I couldnt access to internal storage in the recovery.
Thanks

maybe u have to do a factory reset first. if u cant do it with twrp try to enter the stock recovery and do it before flashing. hope that it works this time.
about me, i was on nougat beta, twrp gives me too much errors when i want to format data and system, i installed stock recovery and did a factory reset and i used dload folder, now im on EMUI 4.0 (B180)
dont worry every problem have a solution. good luck
Posted from Mate 8.
Or with Rollback UPDATE.APP.
My Mate 8 is L29C636,i convert to AL 10 with B577 and go Back to L29 C636B211 without any Problem.
I can upload the UPDATE.APP later 92mb.
Use HiSuite via PC and roll back by updating to earlier versions! It's simple

And how did yo do? Can you explain please?
Copy the Rollback UPDATE.APP in dload Folder in Micro SD.
Change oem.info and custom.bin from AL10 to L29.
Boot in Bootloader and Flash Stock Recovery and reboot
This make Automatic a Factory Reset and Lock my Bootloader
Go to dailer and use this code *#*#2846579#*#* and go to 4.Software Upgrade.
After this Procedur copy my Original Firmware for c636B211 in dload Folder and make the same Procedur with *#*#2846579#*#*
After flashing the Firmware i am on L29C636B211
But you have a AL10,i think you flash the Rollback Update App
This Roll Back flash to Emui 4.0 and not to 4.1
After flash the Rollback,Download a Firmware for your AL10 with Emui 4.0 and flash this Update App via dload *#*#2846579#*#* here
This Methode can use with locked bootloader
Download Rollback
I think this works
If not take what was described above

Hi there, I got a problem with mi Huawei Nova CAN-L01 Tim-Branded (italian)
I flashed with three buttons method a full EU firmware no-brand B350, so with "dload" folder I successfully updated both
Huawei Nova B350 CAN-L01 Nougat Update.zip
Huawei Nova B350 CAN-L01 Nougat update_data_full_CAN-L01_hw_eu.zip
at this point I faced the annoying "NRD90M test-keys" version problems (no themes applicable, no OTA, no EQ control etc etc)
then my goal was to turn back into my original stock-brandend firmware.
Thanks to "FirmwareFinder" I found both latest full OTA packages for CAN-L01C55B340. But while I try to flash the first (or anyone) of them, then suddendly update fails after 5%, with "system package error".
I also tried to flash it all in fastboot mode, so:
- unlocked bootloader
- extracted recovery.img + boot.img + system.img from first CAN-L01C55B340 and cust.img from second CAN-L01C55B340
- successfully flashed all with fastboot
- still having "NRD90M test-keys" version, still unable to manage and apply themes
at this point I also tried to re-flash stock firmware CAN-L01C55B340 with "dload" folder method, still having "update fail after 5% with package error".
I managed those solutions taking a look at the thread CAN-L01 "NRD90M test-keys" problem but I can't find a fix for my problem.
Would it be necessary taking some actions with TWRP? Or what?
Thank you all in advance for your suggestions!
Update: I finally ended up with dc unlocker solution.
Flashed through fastboot-mode both files of original B340 stock Tim-branded firmware.
Now my system is again with the right built number, without "NRD90M test-keys".
But I'm facing some problems beside
- I still can't perform a flash of both original B340 packages via "dload" method (again, after 5% shows me up "wrong package")
- In eRecovery mode I tryed to download and restore system via Wi-fi, also there I got error on package
- My Bootloader is unlocked, even if I try to relock with "fastboot oem relock MY_CODE_NUMBER", I got the device prompt asking me if I wanna relock and perform a factory reset, I proceed with "YES" but the device simply reboots without relocking with shell prompt error FAILED (remote: write oeminfo fblock stat info fail, error num:13)
I have bricked my M3, and was successfully revive it using IDT board software. And now i stuck at the old ROM
I was trying to upgrade using SD Card method with many dload file but no one success
Please help me to figure it out, thank you
=====================================================
As I mention before , i was sucessfully flashing board software which bring me to basic firmware.
I try to update using USB OTG and SD Card but I got no luck.
Then I use fastboot to flash this firmware [HUAWEI MEDIAPAD M3 8 FIRMWARE (BTV-DL09 ,C100B009, EMUI4.1+ANDROID 6.0) [ANDROIDHOST.RU].RAR]
Extracting UPDATE.APP and take out boot, recovery, cust, and system then using fastboot to force flash
* Reboot into fastboot by pressing vol down button (phone off) while connect USB
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
This method bring me to EMUI 4.1 on Android 6.0 as mention above
But i have some problem here :
* My SIM got locked
* I cannot update to EMUI 5/ Android 7
What I was done :
+ copy file UPDATE.APP of EMUI 5 to dload folder than update via USB OTG. I use this file [BTV-DL09C683B352CUSTC683D001 FIRMWARE ANDROID 7.0 EMUI 5.0 05014EAR.ZIP]. But I got messaege "No update file found"
+ Exctract boot, recovery, and system from update.zip and cust.img from update_data_full_hw_eu.zip then flashing using fastboot . But it end with bootloop
+ Flashing update.zip via TWRP. It was success but failed to grab EMUI info or firmware version. It show NRD90M test-keys on it. TWRP red log
Failed to mount ........ (forgot what was failed, only remember there were 2 invalid argument) (invalid argument)
Please anyone give me a clue to update my M3 to newer version.
Target : move into M3-BTV-DL09C100B307 or M3-BTV-DL09C100B311
PS: I have M3-BTV-DL09C100B307 file (update and update_data_full_hw_eu)
I also have M3-BTV-DL09C100B311 file (update.zip, update_data_full_public.zip and update_full_BTV-DL09_hw_eu.zip)
Thank you
Update.app should match your device in order to be able to flash it via dload method. As I can see your device it's not properly updated to EMUI 4.x Android 6
