Default [GUIDE] How to extract Huawei firmware (update.app)

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. Iím french and itís possible for me to misspellings

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


I. What you will need


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:
Select Code
perl split_updata.pl update.app
on terminal, it gives me
Code:
Select 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.

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.
