How to extract Huawei firmware / update.app

I wondered how to extract the firmware files Huawei, since with the dsixda's Android Kitchen I could not do it. After some research I finally found and I share my method in this thread.
This method works for the newer firmware (i tested on JellyBean Emotion UI 1.5) but should also work on a lot of others version.
Please for all improvements, send me a MP. I’m french and it’s possible for me to misspellings

This thread is in constant progress thanks to your feedback..

I. What you will need

ActivePerl to execute the script that will extract update.app[/URL][/B]
JoeyJiao's split_updata that i have modfied
Winrar
The Huawei update.app you want to extract
Android ICS JB EXT4 imagefile unpacker
A brain =)

II. Download and install ActivePerl

1. Download ActivePerl
2. Install it:

3. It's okay for ActivePerl

III. Install script to extract update.app

1. Create a new folder on your Desktop named "Huawei ROM extract"
2. Download this script (I modified it to work properly) in the folder "Huawei ROM extract"
3. Put your update.app in the same folder
NB: It have to be named update.app !!!
4. So you folder look like this:

5. Double click on split_updata.pl
6. This window will appear, just wait:

7. When it finish the window is closed automaticaly
8. In your folder this is a new folder named "output", open it
9. You will see some files like:

10. It's okay for extraction

III. Find system, boot and recovery files

1. Download my script HuaweiFinder in the folder "Huawei ROM extract"
2. Execute my script with a double click, youwill see this windows:

3. It's done, go into ouput folder and you will see some files:

boot.img is the kernel files
recovery.img is the recovery
system.img is the rom
others files are some others system files

III. Open and extract img

1. Now download Android ICS JB EXT4 imagefile unpacker
2. Extract it in the folder "Huawei ROM extract"
3. Open ext4_unpacker
4. Double clic on ext4_unpacker.exe

5. Clic on this icon:

6. Go to the output folder and select system.img clic on "Open"

7. Now select all files, right clic and clic on "Extract"

8. You will see this:

9. It's okay the ROM is extracted where you have choosen !!

I hope this guide will be helpful!! And don't forget to thanks

Thanks for the great guide, but I have a problem executing split_updata.pl. when i double click it, a terminal just opens and closes itself in less than a second but there is no change. I installed the active perl in the link. Any idea?

Edit:
If i type

Code:

perl split_updata.pl update.app

on terminal, it gives me

Code:

Unrecognised file format. Wrong identifier.

And it makes a folder named "output" in the directory, but nothing is in there.
The update.app was in the update.zip from B522 to B601 for ascend d1.

So this is an OTA update and not a full rom

Thanks so much for sharing this. But I got a bit of a problem where you execute huawei finder script to find the boot, recovery and system image. Mine got only the system image and not the boot and recovery image. The update.app I extracted from is 389mb. Can you please clarify me on this? Where did I do wrong? I believed I followed every steps as shown.

I am having problem opening .img files as the ext4_unpacker.exe returns wrong file format everytime I tried to open it. I have redownload this exe application many times but still same result

Any solutions?

What happens when updating?

I'd like to know what happens when updating because I have a stock update.app for my phone u8681 wind and it refuses to finish step 2/2 and always fails. I was thinking maybe I'd modify the update package so that it would work but first I need to know which checks it's failing at.

Also I want to know how to repack the modified update.app

Mr-Dutch · Aug 7, 2013 at 7:29 PM

I've got the same issue with boot.img and recovery.img.
Im using the full rom for Huawei Ascend Mate.
Btw, everything else worked!
Thanks!

I also tried your method of extraction but got an error...!
I could not find the boot.img and the recovery.img files from the original firmware...!
could you please share the original firmware with me and any of the custom rom if supported...?

waiting for your reply...!
