nice job!!!-help request

first of all Nice job creating tasks like this is out of the ordinary and i want to tell you that i admire your knowleddge and your patience.
A request now, i have a huawei g520 t10 as my second phone due to my travels for job purposes to china,the phone is tdscdma and i can use
3g in china telecom networks.The phone has cwm recovery automade (thanks arm1 for the good job) with droid tools,and miui v5 unofficial (thanks someone in china....) and works more than decent, in fact no bugs at all.Till yesterday at least that my 2 years old daughter managed to erase the imei from the device while i was preparing her milk as i had the phone connected to the pc with droid tools and i was trying something she pressed the mouse and she changed the imei but in fact the droid tools erased it and i can not get it back.Droid tools wont work (no device on ptty....error),mobile uncle and engineer mode in generall (error sending the command in at),terminal emulators wont touch this system file.......Anyway i figured out the only way might be if i lad the original rom again but since i have cwm recovery i cant,thats where i need your help
i extracted the rom your way(pretty easy and user friendly) but i am missing boot and system img,anyway even if i had it my knowledge ends somewhere near.....and i dont know how to make it flashable to cwm.Would you be kind enough to help etheir by guiding me or by preparing the zip file by the app file for me (that would be huge).ANY HELP WOULD BE HIGHLY APPRECIATED.

Hi,

Many Thanks for the great post, it helped me too much.

Actually the script didn't rename the files correctly, I was looking for the recovery.img file and I managed to find it by trial and error ;)

I hope if you can update the scripts in order to find the new file sizes.

I've the same output but with a little bit differences in system.img, unknown_file.7.img and unknown_file.14.img.

G526_output.png

I suppose it's because I've installed a different firmware, isn't it?

G526_firmware_(G526-L11_Android 4.1_Emotion_UI_V100R001C86B191_Spain-Yoigo_05011UPY)

How did you? Could you explain it? everything worked fine (screen, camera...)? Which android version is installed? I'm trying to get the android 4.2.2 from G740 and bring to G526 and I don't know where to start...

    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



    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:

    1906043311.png

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

    2006861512.png

    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

    5752007913.png

    5. Clic on this icon:
    5070577914.png

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

    7216531315.png

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

    if you mean the size of the update.app i used, it was about 10.26mb

    Edit

    here is the update.zip for the update.app file
    Click to expand...
    Click to collapse

    So this is an OTA update and not a full rom ;)

    Hi,

    Zittoro said:
    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.
    Click to expand...
    Click to collapse

    It's stange... Which is the size of the file ?

    misha84 said:
    great tread!
    but for ascend y300 don't work very well..
    it dont' recognize boot.img and recovery.img
    Click to expand...
    Click to collapse

    Send me boot.img and recovery.img, or give me the rom link. I will try to fix that

    Hello to community.
    For the first - big thanx to developer of this tool and author of this thread-

    Im a newbie here with a poor knowledge of English, but I will try to do my bests to desribe my situation.
    I deleted everything from the phone Huawei G6 - L11 (also know as G6 4G) via TWRP (by mistake) and I would like to recover my phone back. I have downloaded the Perl Package Manager. The first thing I can not find is a mentioned script (split_updata.pl) mentioned on the first page of this theme.
    May I ask someone from the thread to assist me with finding the right script and to provide me a guidance to pass throug this work? Any help will be appreciated.
    Regards

    here is my How-to about extracting huawei update.app. with links added.:
    note that i use ubuntu not windows.

    extract huawei update.app:

    https://github.com/marcominetti/split_updata.pl

    # copy splitupdate, crc and UPDATE.APP files in same folder.
    cd in that folder.

    chmod +x splitupdate
    chmod +x crc
    ./splitupdate UPDATE.APP


    then copy system.img in another folder

    download simg2simg

    https://xdaforums.com/galaxy-tab-3/development-10/dev-simg2img-makeext4fs-binaries-mac-os-t2865515

    I was able to use simg2img like this:

    sudo apt install android-tools-fsutils


    simg2img SYSTEM.img SYSTEM.img_raw

    Then you can do
    sudo mkdir /media/<username>/temp

    and afterwards

    sudo mount SYSTEM.img_raw /media/<username>/temp


    open it via terminal such as

    nautilus /media/<username>/temp

    You should be able to copy out of the mounted directory.
    You cannot make dirs and files in the mounted dir
    But if there is a problem you can do

    chown <username>:<username> /media/<username>/temp
