what do you want to do with the img? dump it or just flash it?

if you got some kind of linux distro installed, just go (in terminal) to the dir where the image file is located, and type "file filename.img" if it returns something like ext2 filesystem, simply do:
mount -o loop filename.img /mnt
and the file will be mounted on /mnt, so you can access it using cd /mnt
if it returns something like VMS Alpha executable, you will have to download unyaffs, and if you want to repackage it later on, mkfs.yaffs2,
to get the file's content, just run unyaffs filename.img, and you will have the file content right in the folder with the img file...
if you don't have a linux distro installed, you can simply get virtualbox, and download the latest ubuntu iso file... mount the file in virtualbox and install ubuntu (it's quite easy)...
oh and incase you need them some basic commands:
Code:
ls - lists current folder content
cd folder - allows you to switch to a specific folder, like if you type ls, and you get the folder android listed just type cd android... if you want to go back to your home folder, type ~/...
sudo command - allows you to run specific commands as superuser (root... you can also just switch to user root by typing sudo su, so you won't need sudo every single time)
rm file / rm -R folder/file - allows you to remove files and with the parameter -R also folders ;)
hope this helped

I don't know how to do it in Windows, but you can do it with the ubuntu .2 for HD2. What I do is copy my data.img and mount the original in ubuntu. the commands I use are:
In Terminal cd to the directory where your data.img is and enter:
mount -o data.img /media/data
You may have to enter if it says the mount point doesn't exist:
mkdir /media/data
Then you can open the img file like any other drive with the file manger.

[***Guide***] Deodexing and Create your own custom rom and share it!

DEODEXING
must have all these
Download XUltimate
Busybox installed
Root
sdk tools
1. Connect tablet to computer
2. Start xUltimate, we will now get the required files from our phone to deodex and zipalign it which we will describe in the 3rd step.
3. On the main menu of xUltimate, type "deodex" in the main menu then choose option 5 (Pull and deodex all). Everything will be done for you here. Don't worry. You will see all your finished files in the folders 'done_app' and 'done_frame' which are located in the installation directory of xUltimate. If you have issues with the mobileprint.apk remove it and the mobileprint odex from /system/app/
4. move folders 'done_app' and 'done_frame' folders to your sdcard, you can find these folders in the directory of xUltimate as described in the previous step.
5. Make sure the sdcard is not mounted to pc anymore
6. Open Windows Command Prompt and type the following commands.
adb shell
su
stop
mount -o remount,rw /dev/block/stl12 /system
rm /system/app/*.odex
rm /system/framework/*.odex
busybox cp /sdcard/done_app/* /system/app/
busybox cp /sdcard/done_frame/* /system/framework/
chmod 644 /system/app/*
chmod 644 /system/framework/*
mount -o remount,ro /dev/block/stl12 /system
sync
reboot recovery
7. Now data and cache reset in the recovery menu...
8. reboot
Now How to Share and backup
1. download the backup script http://www.multiupload.com/OBLSBY5Z9E
2. extract the file and place in C:\Program Files\Android\android-sdk\platform-tools or where your sdk platform-tools folder is
3.open command prompt [run cmd prompt as administrator] type "cd C:\Program Files\Android\android-sdk\platform-tools" next press enter then type "backup" or where your platform-tools folder is [don't include ""]
4. the files for heimdall sharing will be in cd C:\Program Files\Android\android-sdk\platform-tools or where your platform-tools folder is also they will be on your sdcard
5. make sure when sharing you do a complete wipe you dont want to share your info
6.now lets get some roms posted!

Nice post, I was wondering how to do this just recently.

[Guide] How to modify yourself system.img partition

Hi
in this thread i want to explain to everyone who want to modify (debloat, add app) to your system.img partition
First is necesary to:
-backup original system.img from your phone (make a copy to your hddpc, dvd, usb stick, disketes ... etc ... lool .. joking)
-injecting root to your system.img
this steps are explained here: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
NOW: before copy and write the new rootedsystem.img image to your phone if you want to debloat or adding new app do this in your linux machine:
- mount again your new generated rootedsystem.img image
Code:
mount -o loop,rw -t ext4 rootedsystem.img operatingtable/
now browse mounted folder (operatingtable) and delete what you want from app or app-priv folder
if you want to delete startup phone sound delete from /media/audio/ui poweron.ogg and poweroff.ogg
in same mather you can add new app to app or app-priv folder but is necesary to chmod folders and files like this:
for new directories: chmod 0755 operatingtable/app/app-directory
for new files: chmod 0644 operatingtable/app/app-directory/app.apk
when you finish do this
Code:
umount operatingtable
and now you can copy and write to your phone rootedsystem.img image
as explained here: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
PS: Of course this debloating could do directly from your phone after gained root with files managers ... but i think this method is easier.
PS2: If you debloated some apps (gapps ) ... Is necesary to restore factory settings because some updated apps are in /data/app folder ... or you can delete from there to.
Enjoy.

Is there a way to browse and edit an unrooted image? Does it have to be rooted to mount, browse and edit files? I'm asking because I am trying to edit build.prop only and I'm getting an error that says I'm not the owner. I copied the first command you posted, but I wasn't able to open the img. I had to drag the file into the terminal after the "ext4" to open the file, but I don't know what to do from there.
Sorry I"m a noob on linux

Hi, hope you're still active with this thread. I have a copy of system.img and I want to change a certain .apk inside /app. It is already mounted but when i try to chmod it says something like "changing permission is not permitted". Do you know how to fix this? Thanks!

Can i do this thing with xiaomi mi 5.

Unpack and Repack Allwinner OS .img

I have a head unit with allwinner T3L.
I have asked for the OS update file from the seller to reinstall and fix an issue. I used Phoenixcard to create the sd card and installed it successfully.
I want to unpack and repack the OS to remove a system app and replace it with another. Also I want to change the boot animation.
I found a few information about unpacking/repacking .img for allwinner but none for my processor and there are not many details on each step.
I tried to create an edited .img file but I’m afraid to test it in case it’s corrupted and I won’t be able to use my head unit.
Here are the steps i followed to build it:
-Unpack img on Windows (I used imgRePacker_206)
Put xxx.img in imgRePacker folder
Run runner.bat and drag xxx.img in cmd window
Get system.fex from xxx.img.dump
-Unpack system.fex on Linux (I used allwinner-kitchen tools)
Put system.fex in allwinner-kitchen folder
Code:
tools/simg2img system.fex system.img
mkdir system
sudo mount -o loop system.img system
cd system
I changed the bootanimation_800.zip in media folder.
I deleted an app from "app" folder and added another.
I changed the ownership to root:root for the added files.
Code:
cd ../tools
sudo ./mkuserimg.sh -s ../system ../new-system.fex ext4 ../tmp 2048M
cd ..
sudo umount system
(here I used 2048M because I was getting errors with 1024M or less)
-Building the new image on Windows
Deleted system.fex from xxx.img.dump
Added the new-system.fex in xxx.img.dump and renamed to system.fex
(system.fex size is different even if I don't make any changes to system folder)
Run runner.bat and drag xxx.img.dump in cmd window
Use xxx.img and create sd card with Phoenixcard
I want to know if I did anything wrong or if I missed any step that would brick my unit.
Thank you

Anyone? I just want to verify if I miss any step in the process.

Unpack first level only with this tool - https://forum.xda-developers.com/showthread.php?t=1753473
Then you can use a kitchen to edit the system/vendor partitions.
Good luck
