How to mount & modify system.img (Ubuntu)

Hi to all. I am a newbie ... but I try to do all my best
Above all please make a directory under /mnt (I called the directory "MyMount1"); "mylogin" represents your login name.
Open the terminal and type the next commands:
-sudo mkdir /mnt/MyMount1
-sudo chown mylogin:mylogin /mnt/MyMount1
-copy system.img & paste it into MyMount1 (computer/mnt/MyMount1)
-cd /
-cd mnt
-cd MyMount1
-mkdir sys/ && sudo mount -t ext4 -o loop system.img sys/
-sudo chown mylogin:mylogin sys (without this command you will not be able to copy and modify anything)
-cd sys
-sudo chown mylogin:mylogin addon.d (without this command you will not be able to copy and modify anything)
-then copy addon.d & paste it into Ubuntu Desktop (now you can make any changes you want)
-then delete addon.d into /mnt/MyMount1/sys
-copy addon.d (into Ubuntu Desktop) & paste it into /mnt/MyMount1/sys
-then apply the same command to every folder inside system.img (/mnt/MyMount1/sys) and repeat the procedure (copy it into Ubuntu Desktop, make changes and paste it into /mnt/MyMount1/sys).

hey there!!! i can give you a couple of suggestion, even if i don't get if you are only extracting or also editing and repacking since i don't see any repack code.. anyway.. first of all you definitely should use -R in yoour chown code.. this means recursive.. so you don't have to do it for every folder, subfolder and so on!! do a chown -r for sys and you're done with it.
then another thing.. i personally use a script that will handle all this by itself, i put it in the file explorer script folder and so you can access it from everywhere just right-clicking on the file you want to mount.. it will need to edit path for pass it as variable, but it's easy.. at least once you know how to
so this is my script:
Code:
#!/bin/bash
CWD=(pwd)
simg2img [email protected] img.img; mkdir /tmp/system; mate-terminal -x sudo mount -t auto -o loop img.img /tmp/system; mate-terminal -x sudo chown -R login:login /tmp/system
just to explain, you see simg2img because i work with sparse img ( from samsung) that must be converted to regular img before get mounted, so i have the simg2img binary compiled and moved into /usr/local/bin path to access it from any path.. you will need to do the same or to remove that part if you don't need it.
also you must change mate-terminal to plain terminal since you're on unity i can see
then move the script to /home/your_login/.nautilus/script (again because you're on unity using nautilus i think) check if it has the exec bit enbled from permission and then enjoy..
oh another thing.. in case you need to copy keeping the permissions and ownership, so that you don't ahve to fix all that later you simply don't set the last part of the script - the chown part, since you can access the subfolders and files anyway and for ex. use the "cp -a /tmp/system/app /your_desired_path to work on it.

Thank you very much for your suggestions
I have to admit that I am a newbie/noob ... particularly on Linux (I have installed Ubuntu OS just a week ago ... I come from the planet Windows). I have tried "android_img_repack_tools-android-6.0.1_r3_x64.tar.gz" ... but simg2img doesn't works (I am not able to convert system.img in raw). I'm trying to mod a system.img Mediatek Marshmallow.
Kindest Regards.

i hano NO idea about mediatek devices, you should ask in the corresponding fora, but most likely you don't need simg 2 img since that's not a sparse img, so you could be able to mount it strait away.. or at least try first without converting it.
what's the error you're getting in terminal?

yeah then is definitely not a sparse img.. maybe a regular img or other kinda of..
you should search for the mtk device forum for this info.. or better yet maybe the @dsixda kitchen has a conversion binary for it, so you can see which is and use it instead of the simg2img.. this kitchen is not anymore updated, so you cannot use it for everything like repack or root, but should work for unpack

Open the terminal and type the next commands:

[GUIDE][Linux/Win] How to unpack system_1.img+system_2.img+...+system_*.img | 2019

A youtube video on this guide
Watch video
Hello guys,
I rarely write guide and tutorials .so neglect my typos and gramatical mistakes
Today im gonna show you how to unpack sparsed system.img files (system_1.img+system_2.img+............+system_*.img)
supports system / cache / userdata / persist / vendor / cust / odm /oem partitions from QFIL firmwares
Lets get started
LINUX
Things Needed:
1) Packsparseimg
2) Imgextractor.exe -Need wine for this
Procedure:
1) First of all extract you device firmware in which you have sparse system.img files in a folder.
(folder path ex:~/Desktop/firmware)
2) Copy the downloaded packsparseimg_v1.1 and Imgextractor.exe in the same folder where you extracted your firmware
(ex:~/Desktop/firmware)
3) Open terminal and enter below commands.
4)
Code:
chmod 0755 packsparseimg_v1.1
5)This command will pack sparse system_1.img....files to system.raw
Code:
./packsparseimg_v1.1
you can use these commands to pack sparse cache and userdata persist,vendor,cust,odm partitions
Code:
Usage of ./packsparseimg_v1.1:
-o string
output dir path (default "./")
-t string
image to unsparse: system / cache / userdata / persist / vendor / cust / odm / oem (default "system")
-x string
xml file to load (default "./rawprogram_unsparse.xml")
6) After joining of sparse system.img's finishes you will get system.raw file
7) Use below commands to unpack system.raw to system folder
Note: You need wine on your linux to run imgextractor.exe
Code:
wine imgextractor.exe system.raw
8) Hell Yeah! you have successfully unpack those system_1,2,3,4....imgs
now you can make your own stock deodexed rom
Downloads For linux:-
[MOD EDIT: URL REMOVED]
Password:innfinite4evr
Imgextractor.exe
WINDOWS
Things Needed:
1) packsparseimg_v1.1
2) Imgextractor.exe
Procedure:
1) First of all extract you device firmware in which you have sparse system.img files in a folder.
(folder path exesktop/Myfirmware)
2) Copy the downloaded packsparseimg_v1.1 and Imgextractor.exe in the same folder where you extracted your firmware
(exesktop/Myfirmware)
3) Open Command Prompt (cmd.exe) and enter below commands.
PS: you can open command propmt by any of these methods. Here method 1 is preferred
Method 1: Most suitable method for this guide
hold down shift key while pressing the right mouse onto the folder you want to open "command prompt" then a new menu item will appear in your context menu offering you exactly that: "open command prompt here" select it and command prompt will open.
Method 2:Search is very helpful. In Windows 7, open the Start Menu and type command or cmd. Then, click or tap the Command Prompt
Method 3ne of the quickest ways to launch the Command Prompt is to use the Run window (press Win+R on your keyboard and type cmd and press enter to open it).
i guess three methods are enough for windows users
4) AFter command prompt opens enter below comamnds to proceed further
5)This command will pack sparse system_1.img....files to system.raw
Note default is "system"
Code:
packsparseimg
you can use these commands to pack sparse cache and userdata persist,vendor,cust,odm partitions
Code:
Usage of packsparseimg:
-o string
output dir path (default "./")
-t string
image to unsparse: system / cache / userdata / persist / vendor / cust / odm (default "system")
-x string
xml file to load (default "./rawprogram_unsparse.xml")
6) After joining of sparse system.img's finishes you will get system.raw file
7) Use below commands to unpack system.raw to system folder
Code:
imgextractor.exe system.raw
8) Now you will get unpacked system folder
Hell Yeah! you have successfully unpack those system_1,2,3,4....imgs
now you can make your own stock deodexed rom
Downloads for windows:-
Imgextractor.exe

[MOD EDIT: URL REMOVED]
Changelog:-
in update v1.1
now supports system / cache / userdata / persist / vendor / cust / odm /oem partitions from QFIL firmwares
Credits:
kidd for initially making packsparseimg binary
@and_pDA for imgextractor,exe(Based on sources ext4_unpacker)
@Innfinite4evr for testing this method and write this guide​

Great work bro :good: Nice job and thanks for this

great work man. thanks

can you share code?

There is another way to unpacj that instead of using wine.
Code:
mount -o loop -t ext4 system.img [path]
Replace:
[Path] with path to the output directory you want (ex: ~/sys-img)
ext4: This might be different, check it by yourself, but most device now using ext4
Thanks for the info, btw

Please can somebody tell me how to revert the process? To create again sparse images and flash via qfil? Thanks in advance!

Well I was Going Through The possibilities of Termux and was extracting .Dat compression in my PC to extract some files out of system folder Then i readed in one xda thread that Termux can install Python,cmake, and all in our Android itself also seen that Python script by @xpirt on @matrixex thread for unpack repack .Dat on pc I seen that this Python script converts .dat to .img Then suddenly One idea arised in my mind Why don't I try that in my phone itself I tried and the result was just insane it worked like a charm in real. Now we want files but it is in .img extension how can we extract that then i Found This app called Zarchiver on playstore You can unpack the image now and use those files or edit them Also i found Another interesting app Android image kitchen by which you can unpack the image and make changes in the image content by import export of files but it leaves the image as it is in .img extension only can edit but can't unpack so the Zarchiver method is the best.....
This can help Rom porters and Rom developing Dev's​
Plz don't forget to hit the thnx button it can appreciate someone ???
I am still a noob so i can't answer Dev's professional questions but I think Other Dev's Moderators and Contributors will help the DEv's​

How you got system folder? Did you mounted system.img to some folder?

I rented dat to img. then I uninstall the file system.img using zarchiver, and in that folder there are build pro files, prive apps etc., and how do I change it back to img ... then to dat

I dont know how to do that from a folder....
But If you are using mobile you can mount it somewhere and tweak it....
Code:
mkdir /data/local/system
mount -t ext4 -o rw,noatime <system.img path> /data/local/system
You can now tweak /data/local/system folder ...
After tweaking that system folder you have to unmount /data/local/system
Code:
umount /data/local/system
img2simg system.img system_sparse.img
img2simg binary can be found in FlashFire apk lib folder for your arch...
Then you have to use img2sdat.py code.....

Your code is wrong...
Place system.img extracted from .dat file in /sdcard/Music folder and type following
Code:
su
mkdir /data/local/system
mount -t ext4 -o rw,noatime /sdcard/Music/system.img /data/local/system
Now you can go to /data/local/system and tweak it and unmount afterwards
Place img2simg binary in /sdcard/Music and
Code:
umount /data/local/system
exit
cp /sdcard/Music/img2simg $HOME
chmod +x $HOME/img2simg
cd $HOME
./img2simg /sdcard/Music/system.img /sdcard/Music/system_sparse.img

Now you can go to /data/local/system and tweak it and unmount afterwards
Place img2simg binary in /sdcard/Music and
Code:
cp /sdcard/Music/img2simg $HOME
chmod +x $HOME/img2simg
umount /data/local/system
cd $HOME
./img2simg /sdcard/Music/system.img /sdcard/Music/system_sparse.img

Question [SOLVED] How to extract files from super.img?

I am using global ROM in TB-J706F but I wanted to extract the original wallpaper from chinese ROM, so I downloaded the one available in lolinet.
Then I did (I am using Linux):
Extract files
Merge super_* to a single file with
Bash:
cat super_1.img super_2.img super_3.img super_4.img > super.img
Extract system_a.img with
Bash:
lpunpack -p system_a super.img ./super
Now I don't know how to mount system_a.img, this is what I tried:
Bash:
> simg2img super/system_a.img super/system_a.ext4.img
Invalid sparse file format at header magic
Failed to read sparse file
Bash:
> sudo mount -t ext4 -o loop super/system_a.img ./system
mount: ./system: wrong fs type, bad option, bad superblock on /dev/loop2, missing codepage or helper program, or other error.
Bash:
> file super/system_a.img
super/system_a.img: data
What am I missing?
P.S.
Anyway if someone has the wallpaper and can upload it somewhere would be great.

Yes, I got some of the commands from there, as far as I understand what they do there is aimed to mount system rw so I shouldn't need it, I tried to mount read only and it gives the same error.
Also I cannot use resize2fs or e2fsck because it's not recognized as an image, I get:
Bad magic number in super-block
I think system_a.img needs an additional step but it's not even compressed, so I'm stuck.

Ok, I solved it.
It was actually very easy, starting from the ROM:
Extract files
Mount super_2.img for system with:
Bash:
sudo mount -t ext4 -o ro,loop super_2.img ./system
The trick is that it needs to be mounted read only with ro.

Nicely done. Did you find the wallpaper?

Yes, it was in system/media/wallpaper.
