no.. why??

For correct downgrade to lollipop, first you make a twrp backup.
Your current version is L04-C432B805 ?
Guide to make a backup:
UNLOCK BOOTLOADER WITH MULTITOOL
Download
TWRP_2.8.7.0_EN_EMUI_4.0_v4.img
AND
ADB
Copy TWRP_2.8.7.0_EN_EMUI_4.0_v4.img in the adb folder,
turn off the device and boot into fastboot mode
in adb folder run cmd.exe as administrator and type these commands:
Code:
fastboot devices
If the device is recognized correctly displaying a series of numbers;
Then type
Code:
fastboot flash recovery TWRP_2.8.7.0_EN_EMUI_4.0_v4.img
fastboot reboot
Disconnect the USB cable and press volume up + power (press 8 - 10 seconds) to enter into recovery.
Into Recovery:
BACKUP (ALL)
After finish save the backup the folder TWRP (with the backup).
After this you flash a stock recovery and stock boot.img of b803 firmware
and install downgrade package for b803, after this, install Lollipop firmware

i tried all the downgrade packages in this thread, but the installation fails at 36% every time,,, what shoud i do... please help
i also have a question.. i always put the update.app in the dload folder in SD card.. should i try to put it in internal storage.. will it differ or harm the phone ??

pudup said:
When I did my downgrade to unbrick my phone, j had put the small file in the internal storage and it worked fine. I had also put the full lollipop package on my sdcard because I had to do both together since i could only access the storages with twrp.
Everything worked for me and I'm on L04. If you're using L02 or L12 there was a thread somewhere here about downgrading.

i am L04 and tried to put it on internal storage and alos failed at 36%
i noticed that any downgrade fails at 36% and any upgrade (tried to 806, 807 and 810) all failed at 5%.. any eplanation or solution for this.. i'm afraid that when the official stable release comes out i won't be able to upgrade to it

pudup said:
Pull the marshmallow update.app file out and flash the boot.img and recovery.img and try again.

i don't know how to do this.. can you send me the files please. i appreciate your help.. thx

Updating Rooted Huawei Mate 8 ROM

I have my Mate 8 running NXT-L29C185B103 with twrp 2.8.7 on bootloader and the device is rooted, I read that it is not a good Idea to update a rooted device because it will not update correctly and I can't unroot the device so is it ok to update or not? by the way I will be updating to NXT-L29C185B180

Flash Stock Recovery,copy the UPdate.APP in dload Folder in Micro Sd,Power off the Mate8.Press Volume + and - and Power Button at same Time for 10 sec and wait the Update Process to finish.Later can install Twrp and Root it.Or flash System,Boot,Cust from B180 via fastboot and wipe Data in Twrp and Root it

I am just worried that something will go wrong, because I don't have the original stock rom, is the B180 version guaranteed to work? I am still a rookie could you please tell me the exact steps to update the ROM on my rooted device?

For me and many User´s is B180 the best Firmware.Best Batterylife and Stable.
Downoad your L29C185B180 update.zip and unpack it and copy the unpacked UPDATE.APP in SD Card in dload Folder.(If no folder dload exists create a folder named dload on Micro SD Card and copy the extracted UPDATE.APP in this Folder)
Download here the Stock Recovery and unpack it.
Copy the extracted RECOVERY.img in your ADB/Fastboot Folder and Reboot the Mate8 into Bootloader.
Flash the Recovery via ADB Command:fastboot flash recovery RECOVERY.img
and: fastboot reboot
Your Mate 8 reboot,after complete booting in System Power off the Device.
Press Volume+/- and Power Button at same Time for 10 seconds and the Mate 8 make the B180 Update.
Wait to 100% and is finish

Bricked Huawei Honor P6 H60-L04

Hello guys, i need your help to unbrick my phone. First of all what i did to brick it was to unlock the boot loader, then used the Honor 6 Multi Tool to get a Cwm on it with it, it was EMUI 3.1 in the choosing. After that my phone restarted and now its hung up at Honor sign, and i can only access Fastboot mode but not recovery. I tried already playing new flashes on it with cust, boot, system and recovery and got a update on my sd card but it didnt work, it doesnt recognize my update and still only shows the honor screen, can anyone help me? Much appreciated

I have the same problem as you... but i don't know the basic informations about the phone (like model , IMEI or other stuff)... so i need help to... THANKS

To successfully unbrick it, follow these exact steps and you'll be good to go.
Download your phone's latest firmware and extract system.img, boot.img, recovery.img, cust.img from UPDATE.APP using Huawei Update Extractor tool.
Flash recovery first, using this command.
Code:
fastboot flash recovery recovery.img
Flash all other extracted files similarly firing these commands.
Code:
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img
After doing this put that very UPDATE.APP from which you extracted the files in dload folder of your external SDCARD.
Switch off your phone, and press Vol UP + Vol DOWN + Power button simultaneously.
Your device will now get to the full stock firmware.

While flashing the above commands, the phone needs to be in fastboot mode right? How to get it in the fastboot mode?

No it's locked. I was unable to get the unlock code from Huawei, am trying for the last 1 month.

Try to get the unlock code coz the message
Remote command not allowed
Is because of bootloader still being locked. There is a way if you can start a chat with honor representative and ask him to give you the code.

There is a unlock code calculator, use it.

You can download the full firmware directly from honor, unzip it, and place the update.app file in a dload folder that you create on your sd card. Power of the phone then hold volume up, down, and power at the same time to initiate an automatic flash of the room you downloaded. This will erase everything, so be aware.

1.Download full rom from huawei support site then extract update.app
2.place it in dload folder using twrp (in twrp enable MTP)
3.Now extract the recovery.img from update.app using huawei extractor and flash it using fastboot flash recovery recovery.img
4.now power off phone then start phone holding Volume Up ,Volume Down & power button simultaneously
5.it will start updating

I had the same problem once.
You can try to flash the cust partition of your phone. The "device verification failed"-message should disappear then. It's not enough to only flash boot, system and recovery. If there is a problem with the cust partition of your phone you can also have problems with flashing stock roms via "dload"-method.
1. Download the right stock firmware via the huawei firmware finder. You usually have two .zip files (e.g. update.zip & update_full_BLN-L21_hw_eu.zip). The image file for the cust partition can be found in the update_full_BLN-L21_hw_eu.zip (choose the right one for your model).
2. Unpack update_full_BLN-L21_hw_eu.zip and extract the cust partition with the huawei firmware extractor.
3. Put your phone into fastboot mode
4. Use the following command: fastboot flash cust cust.img
5. Try to boot into your stock rom.

Help with Mate 8 L29-C185-B580

Hello,
I tried to root my mate 8 nxt-L29c185b580
first I unlocked bootloader and install twrp recovery but happen an errors during flashing superSu and the root not work properly. I tried to return to stock but not work I tried B580 and B321 but not work on dload mode also the eRcovery not work, after that I relocked the bootloader but the device now is stacked with the boot and eRecovery apper without work , also I can not open the bootloader because I cannot access the product id from the dialpad
I need the stock firmware or any thing make the phone work please help
thanks

to fastboot
reboot phone, and power + volume down hold
if not connect usb and try it again
then unlock bootloader
twrp
wipe partitions,
you can install throght twrp
for flashing you can try this manual:
https://forum.xda-developers.com/mate-8/general/how-to-install-nxt-l29c432b560-official-t3540042
if you want B321 i think, you need to downgrade EMUI 5 (with rollback)
or you can try flash B580
- you can try srk tools for unbrick

Ok

Thanks for your reply
But I can not open the bootloader again from huawei website because I only have imei and sn but not product id (the phone stacked on eRecovery)
Do you have any way to retrieve product id via fastboot?
Which firmware you prefer to flash ?
Thanks

I found this method can any one explain how to do that in details
Also I need stock firmwares c185b580 and c185b560 where can i found them?
The method is
Hard methods, Flashing with fastboot
Download Tools and driver :
ADB-Fasboot-tools.zip –>*Download Here
ADB-Fastboot-Driver –>*Download Here
Huawei Firmware Extractor tool .rar –>*Download Here
1. Downloader rom (UPDATE.APP) put in Huawei Rom Extractor folder.
2. After you puted “UPDATE.APP in folder you first run “split_updata” and it will create “output” folder with extracted files(It script will not work without ActivePerl installed on your computer.)
3. After “split_updata” finished you need to run “HuaweiFinder” script and it will compile “system.img” and “boot.img”, you need cut or copy “boot.img”(18mgb) and “system.img”(1gb img file) in fastboot folder.
4. Reboot your device into bootloader(holding Vol- and power button)
5. Now follow this guides ->*How To Unbrick / Update Firmware Any Android Devices Via Fastboot Mode
