[GUIDE] Noob Friendly RFS Browsing/Extracting Guide

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.

[Q] EL30 temporary ROM from SD card

Can someone please help I've been looking everywhere and I can't find the right answer. I read a forum-http://forum.xda-developers.com/showthread.php?t=1464791, and I just don't know at all how to "unpack" the tar.bz2 file?

You have to unpack it with all the subdirectories with something like 7Zip. Then copy it exactly with all subdirectories to your sd card.

I know that , but how do you unpack it? (I'm really new to all of this)

I mentioned the app called 7zip. Install it on your computer.

Im aware of 7zip and I have installed it, but i just don't get what unpacking is and how to unpack

Isn't the tar file supposed to become a zip file and then you flash that... so if you extract that tar file (which I did and) it still becomes a tar not zip.

How to Deodex Sony Ion (for noobs)

I know there is already a thread on how to deodex rom but i need help in figuring out how to rename the folders they are talking about. Can someone please inform me on how to do this. I'm a noob to the ion but i know how to do a few things since my old Samsung Infuse 4g was rooted and ran a flashed rom. I never heard of the Deodexing thing though, help would be much appreciate!!!!

What are you talking about - rename? look at post #2 - deodex your rom in the development thread. Post your question(s) there. I'm sure ganeshbiyer can help you out.

When I say rename the folders it means, if you are using xultimate, to get all your apks and frameworks, the folders created by the utility is origi_app and origi_frame, so rename them to app & framework respetively. The folder names created by the utility you use to get the apps and frameworks may give you different folders. But for the purpose of deodexing the directory names containing should be app and framework.

Use adb pull is alot simplier!
For Apps
Code:
adb pull /system/app /Deodex_CWM/system/app
For framework:
Code:
adb pull /system/framework /Deodex_CWM/system/framework
Now you can go to my computer c:\Deodex_CWM and zip the system folder, then move the zip file to kitchen.

Thanks for helping me get through that. I'm stuck on step 10 now the version of x ultimate i have doesn't have a "24" option to choose from, and when i go to the 2nd menu the numbers go from '1-9' and then jumps to 99.

When you start cygwin for the first time it creates your home/user name folder. Copy from kitchen folder to the cygwin/ home/user name folder using explorer.
After copying go into the from kitchen/ kitchen folder and execute the command
chmod +x menu
./menu

How to extract stock ROM to retrieve certain files

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

I guess I give up

Well, I have have the zip file for CM10 on phone (download folder) and pc and explored it to find the boot.img file to extract to find out it is not there, not only that but I cannot seem to find a way via either my pc or file mgr apps (i.e. root file manager) to move both the cm10 zipfile and gapps zipfile to the root folder on my phone, so I am at my wits end and guess I am stuck with ICS which I really am not at all impressed with.
So basically I am beginning to believe that it is not really possible to do this

There are some stock kernels with recovery in the development section. Find them and read the OP. Flash them and then flash the zip via recovery. The zip can be anywhere, doesnt have to be the root folder.

Thanks so much for a little direction, found the recovery file that I need so that I can actually get into recovery mode. But, the one step I didn't see posted was do I unzip it on PC or phone before executing install.bat?
