Does someone know how to mount/read/edit the .img files in the ROM?
I Know it is a small filesystem.
I googled for an hour and still don't know how it works.
For example the Radio ROM, i'd like to read the contents, Why is it for about 25MB's
Is it possible to tweak the contents and stuff.
Not sure about radio rom.
unyaffs for system.img
unpack-bootimg.pl/repack-bootimg.pl for boot.img
I think you want unyaffs. I used it to decompile a nandroid backup .img so i could take some files form it.
EDIT: Damn you Adam!
unyaffs says `Broken image`
So that won't work.
will try: unpack-bootimg.pl/repack-bootimg.pl
but i think it's for the boot.img file.
also intresting to look at.
Ok guys,
So after having seen a million and one questions on how to extract RFS files and all the complex answers we keep getting on mounting rfs files in linux and blah blah blah (all a waste of time if all you need is to view/extract files from an RFS file from some firmware)... and now there is no excuse for those few requesting other members to extract stuff for them.. you can do it yourself!
Here is the easy/fast way to do it without having to go through all the trouble
NOTE: This, mind you is mainly for extracting/viewing. Not for editing RFS files.
Go to:
-http://www.magiciso.com/
-Download MagicISO (its free trial but that don't matter for viewing/extracting)
-Install
-Open MagicISO
-Hit File->Open
-In the section "Files of type:" - Click the drop down and select "All Files (*.*)"
-Select RFS file of your choosing (For example: factoryfs.rfs where all firmware apps are located)
and..
VIOLA!
Browse/Extract anything you need... No hassles.
To extract you can simply click and drag to another folder/desktop as needed
Cheers!
TY for this guide. Unlike htc hd2 forums I really have hard time getting answers to my questions in tab forums so this kind of guides helps me very much. Again TY.
You sir, are very welcome!
Glad it helped. Thats what we're here for!
Make it a sticky !
add it to the wiki rather than making this post sticky. http://modadroid.com/index.php/Main_Page
Just tried it with UltraISO. It seems to work, too.
Thanks

MagicISO didn't work for me. I copied the .rfs file to a directory on Linux and mounted as read/write and was able to modify the file system. Then, I unmounted it and flashed the changes to my GT using Heimdall.

This guide is only for browsing and extracting RFS files hence the name. It is not for modification.
I'm aware of what the original post was explaining. I tried that solution and it failed. That's why I suggested another method. MagicISO didn't work for me. If others try it and it doesn't work for them either, at least they have another solution that will always work and the option to modify the file system, if they so choose.

That's the Linux command line, right ?
#mount -o loop factoryfs.rfs /mnt/rfs
Otherwise on Mac OS X, you can use this:
#sudo mkdir /Volumes/RFS
#sudo hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount ARCHIVE.rfs
#sudo mount_msdos /dev/disk{n} /Volumes/RFS

Please don't forget when you finished on OSX to run:

Didn't work for me either. MagicISO did extract four files only from factoryfs.rfs.
Two were exe files of significant size... Samsun_Mobile_USB_Driver.exe, and ToolLauncher-Bootstrap.exe.
All the files apk files are probably empedded in the first of those, but no further extraction was possible from the .exe file using MagicISO.
I'm trying to find the origianal VZW Vcast apk files that I stupidly deleted instead of just renaming. I need them so the EC02 update script will run. Any ideas, anyone?

you could look up the long way of mounting and extracting RFS.. Its a major pain though, why dont you make a post asking for those missing files in the forum.
Better bet.

one question: I am unable to extract one particular factoryfs.rf of one rom, MagicISO says it is not an image file. Can you help me there?
Use linux disk reader to open ext4 files (even .rfs files can be ext4)
@neo yea magiciso says so on ext4 archives

HELLO TO ALL THIS IS A SOFTWARE FOR WINDOWS USERS AND WINDOWS SERIES THIS CAN EXTRACT SYSTEM.IMG FROM STOCK ROMS U SHOULD TRY THIS

simple way to extract files from *.img is put in your sdcard (ex: system.img), mount to folder and backup using tar
Code:
cd /mnt/sdcard
mkdir -f system
busybox mount -o loop,ro system.img system
busybox tar -cf system.tar system
busybox umount system
you got your system.img content in system.tar file. if you extract in linux you got original file attributes.

1.DOWNLOAD STOCK ROM OF THAT DEVICE LIKE MINI,ACE,FIT,Y,Y DUOS,SGS, SGS2,SGS3
2.EXTRACT PDA OF THAT DEVICE WITH WINRAR OR 7ZIP,WINZIP TOO MANY SOFTWARES ARE THERE

it is not easy on phone but on computor it becomes easy
bro this for windows 7 and series that is easy for u r using linux but we are not using it
Somekill i know ur purpose but i think irfan info is very usefull.
Why don't u make this thread general information to extract *.img from windows and linux.
If u don't have good knowledge of linux (same with me - lol) u can add link to irfan or other member that have knowledge to share.
This can be usefull thread not only in sgy but other device i think and hope usefull info not gone with spam or junk thead.
All we need is usefull information and applicable to sgy so can make our device more better.
Hello all,
I sold off my note 2 but i miss the ringtones that it had. I want to extract them from the stock ROM and use it in my current device.
I extracted the .tar.md5 file and a few .img files appeared. I tried to extract / view the system.img file but I couldn't. These programs couldn't read the .img files.
What should i do?
You need to convert system.img file to ext4
Then you can mount that on Linux.
Or
Simply request someone to port from device, that will be easy with root explorer.

Thank you for pointing me into the right direction.
I used this Wonderful tool and avoided opening the file in Linux
http://sourceforge.net/projects/androidicsjbext/
- I unzipped e.g. T705XXU1ANF from samdownloads.de.rar.
- Then I opened the T705XXU1ANF7.tar.md5 and extracted the *.img files with winrar.
- Then I tried to mount system.img / recovery.img with OSFMount.
Mounting worked but non of the ext2 tools (Ext2Fsd, ext2explore, explore2fs-1.08beta9, Paragon ExtFS for Windows, LinuReader ) would recognice the mounted image or could mount the image itself to view the files.
For ICS/JB I read about ext4_unpacker. Do we have something like that for Kitkat ? Or is it possible under Linux (I am a noob there)
Basically on Linux, it's really easy.
mount -o loop disk1.iso /mnt/disk
Or wherever that you want it to be.
did one of you mount an system.img from Kitkat Stock Rom already ?? Because I dont think ist about W7/8 .... some of the tools listed should be able to read ext4 ... (ext4_unpacker wont work either !!)

no it cant be mounted that way... I tried under unbuntu LiveDVD. the System.img can be mounted, but there is no readable filesystem. So it must be processed in some form like ext4unpacker did for ICS/JB ...

You're right... I thought it worked out of the box.
Anyway, I used RKwinTools to extract the system.img contents on Windows.
Place system.img in RKwinTools_v133\unpack\firmware\image\
Run the batch file and select option 6 and you'll find the contents under RKwinTools_v133\unpack\System

THX unpacking worked like a charm, but is there also a way of just converting the img to one that is a mountable.ext4. This one I could use under Win and Linux as it would keep permissions ... (Simg2img didnt work)
This is the error:

Well option 7 will convert the sparse ext4 image to a normal ext4 image. The message shows error but it would seem that it's converted. Find the image in the same location that you placed system.img.
Mount system_ext4.img on linux using
Code:
mount -t ext4 -o loop system_ext4.img /mnt

THX so far, I can mount it on my Linux PC not under Win8
- Linux Rader still cant open it
- I can Mount it with OSFMount, but neither paragon ExtFS nor ext2Mgr recognice the mounted Drive ????
