editing IMG files

Can anyone recommend any good tools for windows to edit the IMG files.
Thanks
Winimage can open and extract but I need to insert a file back in.
Thanks

Get Linux and you'll have all the tools for free.

Use Linux live CD!

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 to install LXDE on samsung galaxy s

So 3 days of trying to install ubuntu on chroot and a little knowledge of linux and terminal, i was rather surprised to log into it and there i was, faced with an LXDE interface.
I want to thank coralic, burningbroccoli, lifehacker, josh_axeY and backfireNL for supplying the information i needed to make this possible.
So a brief overview of whats going to be done. First we will need to root our galaxy s in order to access terminal. An ubuntu image will be created and used in chroot environment by mounting (loading) it. Finally a vnc server will be setup and will be logged in using androidVNC.
So for the guide i suppose!
Guide:
First your going to need to root your phone. This is to access terminal and enter the commands required. This is taken from backfireNl's easy way to root your phone.
1. Download: 2.1 Update .zip
2. Put update.zip to root of /sdcard (not /sdcard/sd) (not on the physical SD card but the Internal SD card/Phone Memory)
3. Turn off phone
4. Hold down volume up + home button + power (tip: release the power button for half a second when you see the samsung logo)
5. Phone will reboot into recovery mode
6. Wait until you see the Recovery Screen and then release the buttons
7. With the volume down key go to the option: "apply: /sdcard/update.zip"
8. Press the home button
9. Phone will start updating
10. Phone reboots... and there you go! your phone is rooted!
So that wasnt too hard was it? Although once you have done this, you will need to download a couple of programs from the market. Goto market and download the following programs:
-Busybox
-Terminal Emulator
-androidVNC
Ensure all of these are installed as this is what you shall need in order to successfully run LXDE on your phone.
Next is the image for the install! i will post up an image file for download although for the sake of people wanting the whole info on how-to here it is.
1) login on your ubuntu machine and fire up terminal.
2) login as the super user by entering "sudo su"
3) you will be required to enter your su password, enter this and you will be logged in as root
4) In terminal enter "apt-get install rootstock"
5) One this package is all installed, enter the following code into the computer terminal:
sudo rootstock -f localhost --login ubuntu --password ubuntu --imagesize 1G --notarball --dist lucid --seed ssh,tightvncserver,lxde,expect
6)The image will be stored in the home folder. The image will need to be a .img file or it wont work. So extract the file if necessesary and rename the file so it reads "ubuntu.img"
7)Now you will need to put the ubuntu.img on the phone. The directory which it needs to be installed into is "/sdcard/ubuntu/"
8) All done for this step!
Ok so you have everything setup and ready to do the fun part! so lets get everything mounted and configured!
1)Open up terminal emulator on your phone
2)enter "su". this logs you in as superuser
3)I found you will need to make the following directories in order to work, so in terminal emulator enter:
mkdir /data/local/mnt
mkdir /data/local/mnt/proc
mkdir /data/local/mnt/dev
mkdir /data/local/mnt/dev/pts
4)enter "cd sdcard" then "cd ubuntu"
5)You will then be in the folder with the image. Type into terminal:
export HOME=/root
export USER=root
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
busybox mount -t ext3 ubuntu.img /data/local/mnt
busybox mount -t proc proc /data/local/mnt/proc
busybox mount -t devpts devpts /data/local/mnt/dev/pts
busybox chroot /data/local/mnt /bin/bash
/etc/init.d/ssh start
6) Although it doesnt seem it, your now into your distro!
Okay so your into your distro but it looks all horrid and "text based". wouldnt it be lovely to see a proper desktop? so lets go!
1) enter into terminal "apt-get install x11vnc" this installs x11vnc to your phone. This may take a while depending on how your connected to the net
2) once x11vnc is installed, type "x11vnc -storepasswd" and enter a password. It will ask to verify the password so enter it again, then enter "y" to setup a password for it
3) first enter "vncserver" to initiate the server on your distro. For some reason without this, androidVNC will start to connect then crash
4)finally enter "x11vnc -usepw -find"
now your x11vnc is setup using a password hooray! last step in this guide and you will be away in no time! So is everyone ready?
1)hit the button on the bottom to return to the desktop but keep terminal emulator running
2)goto androidVNC and enter the following:
Nickname: root
Password: (whatever password you setup in x11vnc)
address: localhost
Port: 5900
color format can be anything, i set it to 4 bpp and use local mouse pointer
3)Simply click "connect" and viola! welcome to your impressive lxde environment!
This has been done before although i tried to do every step, base it around the phone as much as possible so no connecting to the computer.
any questions or problems i will try my best to help you guys, and thanks for the guys who helped me on this voyage.
i will write a bash script soon to try and incorporate as much of the manual typing in as possible
good luck!
Things which need to be done:
Upload image: Completed! - http://www.megaupload.com/?d=H55O5UEM
Bash script for terminal emulator: Completed, needs to be uploaded
Bash script for setup process of terminal emulator: Not completed
Startup script for image: Not completed
Youtube video: Not completed
Include internet browser and x11vnc in image file: Not completed
If anyone has any recommendations on how to make the process easier please let me know and i will try my best

Good to see the info consolidated into one post!
Cheers for the shoutout.

no probs your information helped me soo much, i just thought it would be good for someone to goto a post and go "oh yeah thats how to do it" instead of going to loadsa websites

i will try it very soon, thank you.

awesome!
When will you post your img file? I'll have a try.
I have no ubuntu installed, I'm using ArchLinux.

okay ive written a bash script to automate most of the process although there are a few things i could tweak before im fully happy
i have also posted a youtube video to demonstrate how easy it is! the first post will be updated with the link.
people ask me the reason for doing this and i have 2 replies:
1)to show the true potential of this phone (and working in a phone shop it really works)
2)for development purposes. Things like this are the next step in unlocking the true potential of the phone
lijgame: Im just uploading it now for you

Good work, will give it a try. And what about any browser ? Like firefox ?

hi.
okay so this is installing ubuntu into a chrooted environment and vnc'ing to it.
does anyone know if it is possible to blow away android and install pure debian on it? does anyone know of a hardware list on the sbc in this thing and what sort of support one might need to hack in to get a such a thing to work?

I will apologise now for the delay in image upload, the image file is 1gb and im having trouble finding a place to upload it.
In terms of installing a clean debian would need more than just a straightforward port. You would be looking at making an environment which supports the arm architecture, porting all of the drivers over, creating an option to support telephony, messages and gps too. If you wanted a debian environment it would probably be best to either run it like how the n900 does or getting a distro of it which is specifically made towards mobiles and modifying it.
Although you have an extremely good point there! Tell you what, once ive got everything running on here i will have a look and see what i can do in terms of atleast getting a debian shell running or a limo version

Just create zip/tar-ball of img file and it will become around 300MB. Then you can upload it on multiupload (or megaupload/rapidshare/mediafire).
I just created that image too and will be testing on my Galaxy S soon, so if its working for me then I will upload my image too.
Thanks for your good work

haha i shouldve really thought about compressing the file really
this will be a pre-image im just working on getting a better image with optimization, x11vnc and firefox

okay guys the first post is edited with the image for the install.
http://www.megaupload.com/?d=H55O5UEM
I am currently in the process of playing about with images to include everything you need, so soon enough i will have an image with everything you need to get started

Tnx for the credit!

Ubuntu image is uploaded and ready to go, im currently working on a better image so when ive finished that, it shall be released.
Also i have recently installed an internet browser and it is functioning properly. I will post screenshots soon

The image is only 11MB and is corrupted
Moreover, I tried to mount my ubuntu.img to /data/local/mnt but it is giving error (sort of -> loop back device can't be mounted: No such file or directory) although I created and checked /data/local/mnt directory which exists

Try creating a second loop device with: mknod /dev/loop2 b 7 0

im guessing because the image is corrupt, your unable to mount it.
I have just uploaded my bash script making it easier to mount each time.
bash script: http://www.megaupload.com/?d=CEU6R5J4
Image file: http://www.megaupload.com/?d=H55O5UEM
ensure you have made the directories explained in my first post.
pop the hsetup.sh file inside /sdcard/ubuntu (along with your image)
then fire up terminal emulator and type:
su
cd sdcard
cd ubuntu
sh hsetup.sh
This mounts everything for you and logs you into LXDE, all you need to do after is type in:
/etc/init.d/ssh start
vncserver
x11vnc -find
Then log in using androidVNC
i will attempt to upload the file to another location and i will test the image file to ensure its not a compression error

i apologise, ive just looked at the zip file and it is corrupt.
just compressing a new one and i will upload it

[Q] how to unpack squashed.sqsh in NAND android builds ??

hi ..
i need help with this ,, i already posted on Q/A forum and didn't get any answers !!
i want to make some changes on the squashed.sqsh file but i can't cause it is read only !!
so is there a way to unsquash it or unpack it and then resquash the file ??
i did some search and found out that this could only be done on linux so i went ahead and downloaded the latest Ubuntu build
and tried this command
"sudo squashfs /home/'user'/desktop/extract /home/'user'/desktop/squashed.sqsh"
the file is on my desktop
but i get command not found ..
i searched and found that i need to download "squashfs-tools" and i did download version 4.1
but now how do i install it ??
the read me says that i have to use "make" command but i don't know how to use it !!
i also searched and it is all complicated and i couldn't figure out the way to install it !!
this is my first time using linux !!
please help cause as for now Android on NAND is pretty much useless for me !!
i'll be sure to make a guide after this .. for people who want to modify the squashed.sqsh file ..

I agree with you too.. Nand is kinda useless for the EU HD2.. TMOUS HD2 are lucky to have 1gb ROM.. these days i'm having nothing on my phone :/

to unpack a squashed image use this command:
sudo unsquashfs /your directory/system.sqsh, this yo will do inside the directory that you have your system.sqsh
then to repack it use sudo squashfs /the unquashed system folder/ system.sqsh
there might be some mistakes its been a while since iv tampered with sytem images squashed. hopefully you have an idea now

thank you very much for the help
it is nice to see that people still care about each other
i actually tried that but i get an error
Code:
Parallel unsquashfs: Using 2 processors

dir_scan: failed to open directory squashfs-root, because File exists
[| ] 0/2805 0%

I can't squshfs.. just unsqushfs, thats all..
EDIT: someone helped me solving all the problems, its mksquashfs.

So, any luck being able unsquash and squash? Have any of you been able to modify system files using this method? I'd love to be able to modify framework-res.apk. Seems like a difficult process though....

I'll try making a tutorial for who doesn't know how to do those methods.

yes please i tried the above command but couldn't get it to work on my machine !!
it says something about failed to access squashed-root because file exists !!!
any help would be appreciated

This can be done within Windows aswell. You just have to grab this package and unzip into a new folder.
Copy the squashed.fsqh into this folder and execute
>unsquashfs squashed.sqsh
it will create a folder squashfs-root.
Now you can edit whatever you want. When you are done use this command to repack. Note that you must delete the old sqaushed.sqsh before you do so or you will get an error message
>mksquashfs squashfs-root squashed.sqsh -all-root
now you can connect to the device with adb and log into shell
>adb shell
And delete the squashed.sqsh on the device
#rm /system/squashed.sqsh
#exit
and reeboot
>adb reboot
The device will stop during boot because the squashed.sqsh ist missing
connect with adb and push the new squashed.sqsh
>adb push squashed.sqsh /system/squashed.sqsh
and reboot
>adb reboot
Done!
Note that this is for gauners Rom. He used squashfs 4.0. Maybe you will need 4.1 for other roms. I don´t know. Not a linux guy

thank you very much for the answer
i got it unsquashed by dragging the squashed.sqsh to unsquash.exe
"because when i try opening the unsquash.exe and mksquash.exe i get a cmd with a bunch of lines for like half a second and then it exits before i even do any thing"
then i tried putting it back togeather by draging squashed-root folder to mksquash.exe and it didn't work ??
i also tried squash-tools 4.1 and the same error happened !!
running out of options here

Ehm... This a command line tool. You have to open a cmd window and cd to the folder where you have the unsquash und mksquash files. The execute the commands.
Do you have adb installed and working? This is part of the android sdk. You will need it to push the file after repacking.

GUIDE : How to modify the cust.img

Hey there.
Does anyone knows how to modify the cust.img file of the latest official 2.3.5?
I want to remove some firmware apks (swype to install another version which support greek).
Thanks!

Hi I got this information from That-Guy:
1. Download Slitaz Linux 3.0 Live CD
2. Open terminal
3. Copy cust.img from phone to /home/tux folder
4. mkdir tmp
5. mount cust.img /home/tux/tmp
6. cd /home/tmp/hw/default/app
7. Delete apk files what you don't want
8. unmount tmp
9. Copy cust.img from /home/tux folder to phone

Thanks. I did the following and worked:
In Linux (ubuntu 10.04):
1)copy the cust.img file from your .cust_backup/image folder of your mobile somewhere in your computer (ex Desktop)
2)open a terminal and type sudo su (root permissions) and then your computer password
3)Go to "somewhere" : with command: cd somewhere (ex cd ~/Desktop )
4)type at terminal mount -o loop cust.img /mnt/
5)type sudo nautilus . This should open you a navigation window.
6)navigate to: file system --> mnt/
inside the hw/default/app are the apks of the default cust.img.
Edit it as you wish.
to unmount type at terminal (with root permissions again): umount /mnt/
you are ready to copy the cust.img back to your phone and replace the old one

can someone give us a clear cust.img and the apps to a folder in order to let us choose which of them we want to install?
I'm not so familiar with linux OS and i am afraid to do it on my own. :/

Make ROOT Permanet / System Read and Write to all Android ROMS for Tenderloin

Extracting ramdisk image to change fstab.tenderloin to make system read and write allowing permanent root access using any ROM ever created for the HP Touchpad.
I am using Ubuntu 18.04.1 LTS 64-bit (All the software is open source and free, you can get the packages necessary for your distro)
Create a folder in /home (root) name it hpboot ( on the PC ) all work is done on the PC.
Open the custom ROM zip file and extract boot.img to the created directory hpboot
Open Terminal in the hpboot directory, all the commands needs to be enter there.
Text beginning with –>># are for information only. Do not paste into the Linux terminal window.
–>># The following will extract images from boot.img file located in the hpboot direcory.
–>># Copy and paste each individual line in the Terminal window one by one and wait until each command finish processing.
dumpimage -i boot.img kernel.uImage
dumpimage -i boot.img -p 1 ram
dd if=ram of=ramdisk.img.gz bs=64 skip=1
gunzip ramdisk.img.gz
mkdir ramdisk; cd ramdisk
cpio -i < ../ramdisk.img
–>>#The ramdisk files are uncompress in the hpboot/ramdisk directory
–>>#Open file fstab.tenderloin using (text editor) change mnt_flags of/system ext4 from ro to rw
–>>#Look like this when change from (ro ) read only to ( rw ) read and write.
–>>#<src> <mnt_point> <type> <mnt_flags and options>
–>>#/dev/store/cm-system /system ext4 rw,errors=panic
–>># Save and close the fstab.tenderloin file
–>># The next 3 steps will repack the files into the ramdisk and merge Kernel to create the finish boot image.
find . | cpio --create --format=’newc’ | gzip > ../ramdiskRW.img
cd ~/hpboot
mkimage -A arm -O linux -T ramdisk -C none -a 0x00000000 -n “TENDERLOIN RW SYSTEM RAMDISK” -d ./ramdiskRW.img ./ramdisk.uImage
mkimage -A arm -T multi -C none -n “Tenderloin RW System” -d kernel.uImage:ramdisk.uImage uImage.Android_RW
–>>#Boot the touchpad into TWRP, connect to PC, copy uImage.Android_RW to the external Micro SDCard.
–>>#Select MOUNT and touch Boot, go back, touch Advanced, File Manager, touch external_sd, select uImage.Android_RW, touch Copy File, touch boot, touch select Current Folder.
–>>#You should have free space on your boot for both images. At the boot screen you will have the option of Android (with no permanet ROOT access) and Android_RW (RW System), you need to install SuperSu. You can use any of the two options or delete uImage.Android and then rename uImage.Android_RW to uImage.Android for one boot option.
You do not need to re flash the ROM, you can add this boot file and use it with your current installed working ROM.
The process works for all boot.img created for the HP Touchpad. If you have a ROM and would like to have system read and write access then you can do this.
Hopefully a Linux Guru will create a script for this, which will automate the process to 3 seconds!

I like tinkering with my TP but I am running @Windows 7 on a 32 bit.. any suggestions?

Android is base on Linux OS.
Install vmware player and run ubuntu as a virtual machine, both are free.

Here's a shell script that automates the process (rename the extension from .txt to .sh). Put the script and boot image file in any directory and type
Code:
./rwcreate.sh
If it doesn't execute, it probably needs its permissions changed.. Right click the file you created, select 'properties'. In the properties window, select "Permissions" and check "allow executing as ..." or type
Code:
chmod +x rwcreate.sh
in a terminal window

Thanks for your help and dedicating your time to make it easier for others.
I made suggestion to the script on correcting an error, on DU forum.
Now is just a click to get it done, but if we were in a perfect computer world, it could be even easier as to connect the HP Touchpad to PC using USB.
Then run the script and everything is complete!
Using adb pull command to get (boot.uImage) from hp boot directory, to PC.
Changes are done as per script.
adb push command new boot.uImage to hp boot directory, all done!
But making it easier, will make it more complicated and having to install more software and confusing!
