So i just wanted to share this info as it has been very helpful to me in my development process. When making custom recoveries you often end up with a recovery.img and with Samsung devices there isn't really a good way to flash those. The best way to flash these is to run the following on a linux box:
$ tar -H ustar -c recovery.img > recovery.tar
$ md5sum -t recovery.tar >> recovery.tar
$ mv recovery.tar recovery.tar.md5
Now you can flash that recovery.tar.md5 through Odin in the PDA tab. Im guessing you can use the same process on any .img file (userdata.img, etc.) you create but i havent tested that. Ive only tested this on recovery.img and it works great.
Sorry if this is old information but i couldn't find any posts in the Skyrocket section and just wanted to share this.
Thanks
Easiest way I've found to flash a recovery img on skyrocket is to rename recovery file to recovery.img and place it on internal SD. (This won't work if your soft bricked and a tar file will be necessary )
Then type: dd if=/sdcard/recovery.img of=/dev/block/mmcblk022 in adb shell or terminal emulator.
That should work for any of our recovery images as long as you rename it to recovery.img and put it in your internal SD. I suppose you could replace /sdcard/ with /external_sd/ if you wanted to flash from external SD. Oh and don't be supprised if you catch a little heat for posting this in dev section.

And not sure if there is a windows way. Try googling for Windows tar and md5sum. There most likely is a way.

funny... nobody bothered to answer this.
The way to do this in Windows as I know:
1. Ensure the fastboot drivers for your device is installed.
2. Acquire the fastboot binary (this is fastboot.exe).
3. Test if fastboot can see your device. Open DOS Command prompt, go to the fastboot binary folder and run "fastboot devices" command.
Example: C:\FASTBOOT\fastboot devices ---> The output should be some sort of serial number.
4. Flash the img file you have via command "fastboot flash boot <image_filename>"
Example: C:\FASTBOOT\fastboot flash boot boot.img

What if this is for the note, where there is no fastboot? I can get to odin mode, or to recovery mode, but no fastboot...unless i'm missing something..??
Thanks
Thank you for the post. I used your method but to flash TWRP as follows:
1. Downloaded recovery file (openrecovery-twrp-2.2.0-skyrocket.img) for Samsung Skyrocket from TWRP website on Linux.
2. Renamed file to recovery.img
3. Ran the following commands to covert IMG file to a TAR file:
tar -H ustar -c recovery.img > openrecovery-twrp-2.2.0-skyrocket.tar
md5sum -t openrecovery-twrp-2.2.0-skyrocket.tar >> openrecovery-twrp-2.2.0-skyrocket.tar
mv openrecovery-twrp-2.2.0-skyrocket.tar openrecovery-twrp-2.2.0-skyrocket.tar.md5
4. Flashed recovery using ODIN as customary.
It worked flawlessly with no issues. I highly recommend TWRP over CWM Touch Recovery. TWRP wipes things cleanly. You DO NOT have to wipe 3x which will reduce the wear and tear on your device.

use samsung tool kit v2.3. i had same issue as u and this page only sort of helped me and i guessed my way to tool kit. you only need to install it and place the recovery you need to transform in its input folder, where ever you installed it. then run it and just follow the instructions its pretty easy.
Thanks for the Pakistanian guy above me for reviving this vital topic ...
this method is great :
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p22 bs=4096
BUT to be sure no leftovers are there :
dd if=/dev/zero of=/dev/block/mmcblk0p22
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p22 bs=4096
Can be done inside Android if you're rooted , and a terminal emulator app is installed ...
nice commands to keep in mind.

Would it be the same approach whilst with custom zImage? and load into PDA tab? or are they any other settings to flash custom kernel with odin... I tried flashing with heimdall v.1.3.1 and 1.3.2 both version results "fail to initialise protocol". could please provide any pointes on how to flash custom built kernel image on S2 lte.
I think I finally find it!!

Hi! First of all, thx a lot really was trying to find this out for a long time. One Question i have tough. I Only used the first command and left it as a simple tar file, flashed it with odin and all was well. So what do you actally do by adding md5sum and then renaming it? Is it better to add the md5sum or does it make no difference?
again huge thanks! I always used mskip toolkit, but i like to not depend on additional software
I believe ODIN will verify the md5 sum of the .img if the .md5 file is in the tar. Just in case your .img in the tar gets corrupted. If that happens ODIN will abort the flash and report something like md5 mismatch

That's strange but command from first post don't work for me. Tablet says about incorrect file (.img, not .img.md5). So I've modified commands to make them work with Galaxy Tab 8.9 and Odin 1.8.5:
Code:
cp recovery.img recovery.img.md5
md5sum -t recovery.img.md5 >> recovery.img.md5
tar -H ustar -c recovery.img.md5 > recovery.tar
md5sum -t recovery.tar >> recovery.tar
mv recovery.tar recovery.tar.md5

I'm sure several people will be wanting this information, so I figured I would post it here for everyone. This will allow you to backup your system and create custom Odin images for restore purposes. For anyone unfamiliar with the Samsung system, they use Odin to flash things to the device, much like HTC has RUU and Moto has SBF. Odin files are either .tar files, or .tar.md5 files.
The .tar.md5 files are .tar files with the md5 checksum added to the end of the file. If you attempt to flash a .tar.md5 file, Odin will automatically check that the contents are what they should be before flashing and proceed with the flash if the md5 is valid, otherwise it will stop.
In Odin, you should use the PDA button for all flashing. The PIT button may be used as well, if we can get a valid .pit file for the device, but for now, PIT won't be used either. Other than PDA, Start/Reset are the only other buttons you need to worry about.
Now, on to creating the backup files. First, you will need your device to be rooted (perm or temp root will work), and you also need to have access to terminal on the phone, either via an emulator or adb shell access. To create the backup files, you won't need a Linux/UNIX system, but you will if you want to create a flashable Odin package. The following will output the files on the root of the SDCard, adjust the "of=" path if you want them somewhere else. It will also create the files for the proper filename for Odin as well. So to create the files, here are the commands you will use from root shell (#):
System:
Code:
dd if=/dev/block/stl10 of=/sdcard/factoryfs.rfs bs=4096
Kernel:
Code:
dd if=/dev/block/bml8 of=/sdcard/zImage bs=4096
Recovery:
Code:
dd if=/dev/block/bml9 of=/sdcard/recovery.bin bs=4096
DO NOT INCLUDE THE FOLLOWING IN ANYTHING BUT A PERSONAL BACKUP
Cache:
Code:
dd if=/dev/block/mmcblk0p3 of=/sdcard/cache.rfs bs=4096
DBData:
Code:
dd if=/dev/block/stl11 of=/sdcard/dbdata.rfs bs=4096
Data:
Code:
dd if=/dev/block/mmcblk0p1 of=/sdcard/movinand.bin bs=4096
The last three files (cache, dbdata, data) may contain personal information, so do not include these 3 files in anything but a personal backup/recovery package.
To create a flashable Odin package, you need to pull all of the files off of the phone/sdcard and onto your computer. From there, you use the following to create the package:
Code:
tar -H ustar -c factoryfs.rfs recovery.bin zImage > package_name.tar
md5sum -t package_name.tar >> package_name.tar
mv package_name.tar package_name.tar.md5
If you want to include cache/dbdata/data in the above for personal use, just add them after the "-c" and before the ">".
There are other files that may be in Odin packages, but they are protected by Samsung and cannot be dumped properly. The files are the bootloader, secondary bootloader, modems, and .lfs partitions. The files would be boot.bin, Sbl.bin, modem.bin (not sure what it would be for the CDMA/LTE dual modem here), and param.lfs. It however isn't that big of an issue that these can't be dumped as the can't really be altered by normal flashing of the device, and are usually only altered via OTA updates.
Thanks for this info imnuts! I unfortunately updated to the new update and would like to go back to rooted but cant until I downgrade.
Thanks!
Thanks for posting this. I'm going to attempt to make a personal backup and then I can factory reset the phone and make a stock version for people to use. I'm haven't installed the update yet either, so I'm hoping this will let people get back to ED1. I've also been playing around with theming using the fascinate community rom theme and ninjamorph to swap files. It'll take a while, but it's currently the only way I feel safe messing with framework-res.

The only thing that would change would be the tar command. If you want to include the other files, it would be:
Code:
tar -H ustar -c cache.rfs dbdata.rfs factoryfs.rfs movinand.bin recovery.bin zImage > package_name.tar
md5sum -t package_name.tar >> package_name.tar
mv package_name.tar package_name.tar.md5
You just need to pull the files from your phone and have them in the same directory that you're in in terminal, and have them named appropriately. It also doesn't matter what order they are in (that I know of), I just have them in alphabetical order for ease of reading.
So im going to try and do the voodoo lagfix for the first time ever but I wanted to make a backup. Im on ED2 and NOT rooted so how would I go about making these backups?

cygwin works!
Edit: Here is how:
1. Search google for cygwin - download
2. Run - you will be prompted to get packages - I assumed "archive" was a good place to start - not sure if you need this or not...
3. When complete you will see a new icon on your desktop - double-click
4. Be patient as it loads
5. Copy the files output'ed from first post to same folder on PC
6. Back in cygwin:
a. cd x: (where x: is the drive letter of the drive that has the folder with the files)
b. tar -H ustar -c cache.rfs dbdata.rfs movinand.bin factoryfs.rfs recovery.bin zImage > package_name.tar
c: md5sum -t package_name.tar >> package_name.tar
d: mv package_name.tar package_name.tar.md5
Complete output of commands:
These files are for the users to personalise their cygwin experience.

See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l [-d] > /etc/passwd
mkgroup -l [-d] > /etc/group

Yes, that's normal for it to be so large as dd will dump the partition, including empty space. If you were to compress it with zip or lzma, it'd drop down considerably.
Not sure about the voodoo part as I've never dumped files from an ext4 partition. I don't see any reason why it wouldn't work, but I'd flash with caution and have another working image ready just in case.

This tutorial is about how to export your /system partition or your own ROM.
Requirements
- ADB Shell for Windows, Linux, Mac OSX or Android Terminal Emulator installed on your GT-S5660
- If you are using Windows use cygwin else use Terminal in Linux.
Process
1. Install Cygwin from here, skip this step if you use Linux
2. Connect the Gio to the computer.
3. a) Open windows command prompt and type:
adb shell
Click to expand...
Click to collapse
3. b) If you use Android Terminal, open it
4. Whether you use option a or b from the previous step type this
dd if=/dev/block/stl12 of=/sdcard/system.rfs bs=4096
Click to expand...
Click to collapse
5. Now you have a system.rfs file on your sdcard.
6. If you use cygwin place the system.rfs in this folder (where you installed it):
C:\Cygwin\home\%yourusername%
Click to expand...
Click to collapse
If you use Linux I assume you have the skill to set the correct paths yourself...
7. Now we are going to pack it into a tarball:
tar -H ustar -c system.rfs > thisismyrom.tar
Click to expand...
Click to collapse
if you have an additional moddified boot.img for example you could have typed this as well:
tar -H ustar -c boot.img system.rfs > thisismyrom.tar
Click to expand...
Click to collapse
8. Add md5 hash to our tarball for security and integrity checks
md5sum -t thisismyrom.tar >> thisismyrom.tar
Click to expand...
Click to collapse
9. Renaming our tarball with md5 extension:
mv thisismyrom.tar thisismyrom.tar.md5
Click to expand...
Click to collapse
10. Happy flashing with odin!
Shouldn't stl12 be system? And stl14 cache?
Also, you could make a shell script to automate part of your process. Scripts can be run from Cygwin and Linux.
Regards,
Darkshado
Sorry! Made a typing mistake. Corrected it!
No need of cygwin, adb in windows cmd will do fine, and use total commander to tarball it on windows, other tools mess it up n can brick your device
Hi!
How can i export the CSC (or all the ROM) from Android 2.2.1?
thanks
I may have got the wrong end of the stick here and this could be the wrong thread, but it does seem to be the most specific to my interest.
I'd like to be of service by exporting my own ROM (Stock Firmware) so others can use it themselves in case of disaster. I started a thread at Samfirmware.com here http://www.sammobile.com/forum/showthread.php?t=3420 because they don't have it on their list for Samsung Galaxy Ace, and I was surprised to see it got 64 views, so I presume there would be some modicum of interest in it.
I really don't have any experience with this but I am fascinated and keen to learn. I had assumed (and I know assumption is the mother of all f*** ups) that I could simply create a CWMrecovery backup and it could be zipped up and exported to other phones. But I read somewhere that this would include my google account details.
Anyway. If you can tell me a) how to be of some use regarding this b) tell me its not worth it but point me in the direction of a place where I can start to learn what to do or c) politely show me the exit sign and tell me not to darken your door again...I'd be most grateful
This will probably get moved, but I do believe it is development related because it is important to everyone who flashes ROMs but can't use ODIN for whatever reason (ie Linux/Mac users).
Seeing all the ROM cookers get asked so much to make system.imgs or update.zips to cater to the Linux/Mac users, I decided it was time to tell people how to just convert an ODIN Tar.
I will tell people how to do it on Ubuntu seeing that is what I have (in a VM), but once I have the patience to install Mac OS in a VM, I shall make a guide for that.
Please note that if the factoryfs.rfs is in RFS format (ie it's a stock ROM or it's a ROM by someone who doesn't like EXT4 for whatever reason), you will not be able to do this. The format the factoryfs.rfs is in (EXT2, 4, JFS, whatever) needs to be supported by your Linux kernel. You can check that by doing cat /proc/filesystems
After a lot of investigating, I have learnt that RFS is a broken version of FAT. You could poke around with it and try mounting it as vfat but I don't guarantee success.
ODIN TAR -> System.img
Download your TAR and save it to your Desktop (I will use Kyorarom Ascendency Beta)
Open the TAR with Archive Manager (or whatever you use) and extract the factoryfs.rfs from it to your desktop. You don't need anything else
Open Terminal (under Applications > Accessories)
Go into superuser mode:
Code:
sudo -s
Make a mountpoint for the system:
Code:
mkdir /mnt/system
Mount the image
Code:
mount -o loop ~/Desktop/factoryfs.rfs /mnt/system
Change directory to /mnt and make the tarball for the system.img
Code:
cd /mnt
tar cvf system.img system
Unmount and clean up
Code:
umount /mnt/system
rm -rf /mnt/system
Copy the system.img to your phone
System.img -> ODIN TAR
Download a TAR from another ROM, and the system.img to your desktop.
Open the TAR with Archive Manager (or whatever you use) and extract the factoryfs.rfs from it to your desktop. You don't need anything else
Open Terminal (under Applications > Accessories)
Go into superuser mode:
Code:
sudo -s
Make a mountpoint for the system:
Code:
mkdir /mnt/system
Mount the image
Code:
mount -o loop ~/Desktop/factoryfs.rfs /mnt/system
Change directory to /mnt and make the tarball for the system.img
Code:
cd /mnt
rm -rf system/*
tar xvf ~/Desktop/system.img
Unmount and clean up
Code:
umount /mnt/system
rm -rf /mnt/system
Put the factory.rfs into a TAR and flash it with ODIN.
Done! Hopefully this should all work nicely for everyone.
Nice One... Should be helpful for ROM Developers to provide system.img for their ROM's...
Nice one. Thanks. Though I don't use .imgs still was quite Informative.

Pretty much do the same thing but from in ADB shell, and instead of the command:
Code:
sudo -s
with
Code:
su
and
Code:
tar cvf system.img system
gets changed to
Code:
tar cvf /sdcard/system.img system
Also I'm pretty sure on the phone, /dev/loop0 is called /dev/block/loop0.

As MacOS is basically Unix you should be able to do the same with/on/in a mac when you open a Terminal/Console (forgot how it's called exactly)....
Wouldnt it be easier if you run this commands?
Code:
mount -o loop factoryfs.rfs ~/Desktop/system
tar cvf system.img system
the mount command mounted it succesfully for me

You can use adb too (but these commands should work on a Mac too, as Mac | Linux -- UNIX (based on)
Or you can always use cwm!
is there also a way to convert system.img to tar files...

Macs don't use a /mnt directory. They use /Volumes, just like how Ubuntu is moving over to /media.
And I don't think the mach kernel supports losetup type stuff. I will make a Mac guide after Christmas.

Hey I was wondering if some1 could help me out here.....so I have a Galaxy Tab 10.1 At&t (sgh-i497) and what i did was accidentally downgraded from JB back 2 ICS using this http://forum.xda-developers.com/showthread.php?t=2130960 zip that i flashed thru recovery...now my WIFI and LTE doesn't work and my modem reads UNKNOWN
I am wondering if flashing this modem img http://forum.xda-developers.com/showthread.php?t=2102895 could fix the problem ?
ive already tried this command dd if=/sdcard/modem.img of=/dev/block/mmcblk0p1 and that didn't do it, so i was wondering if some1 could show me how to make this modem.img into a .tar or flashable zip so that i dont have to send it back 2 Samsung.
Any help would be greatly appreciated AND i am willing 2 throw some $$ 2 whoever can help me out
thanks in advance and i hope this is the right place 2 post this request.
There are guides. But the last time I was trying to do this it looked like linux was the only way. Goodluck. Let us know if you find a way

RE: .img to .tar didnt work
Ok so I tried placing the modem.img in the home folder of Ubuntu and ran the following commands
$ tar -H ustar -c modem.img > modem.img
$ md5sum -t modem.tar >> modem.tar
$ mv modem.tar modem.tar.md5
and then tried flashing it thru Odin and it FAILED
any ideas?
First the disclaimer:
I am not responsible for what you do to your phone. Following these directions could cause you to brick, locust plague, or end of times. You assume ALL responsibility for what you do with this information.
Now, on to the fun stuff. I take *NO* credit for this information at all. I am a student of people far more knowledgeable about these things. However, I've managed to take what I've learned and apply it in really fun ways. For example, I have a script that takes an OTA and builds a new full ODIN image from it...with all partitions fully signed except system. Many people have asked me to "repackage it" with various requests. This tutorial is going to show how to do that.
Requirements:
o) You will need to install Cygwin. A default installation should suffice for this exercise.
o) You will need one of the ODIN TAR Full Rooted Restore images. They are gzipped to make them smaller.
Process:
o) You need to unpack the files stored inside the gzip. 7 Zip is a handy program for doing that. We need the individual partition files extracted to a work directory that can be accessed from a Cygwin command prompt. I create a C:\Android\S4_GPE directory for my own image creation tasks.
o) Once the individual files are unpacked, we need to repack them. Open a Cygwin command prompt and navigate to the directory you extracted the files to. In my case, that would be cd c:/Android/S4_GPE
Follow the directions below to repack the files as needed. I give a few examples here to show you the basics of how it's done. Basically you run each command in your Cygwin command prompt. Or you can add them to an SH script and run it that way. Whatever you feel most comfortable with.
The output of these commands is an ODIN flashable file that will install what you choose.
BOOT
filename=boot
tar -H ustar -c boot.img > $filename.tar
md5sum -t $filename.tar >> $filename.tar
mv $filename.tar $filename.tar.md5
RECOVERY
filename=recovery
tar -H ustar -c recovery.img > $filename.tar
md5sum -t $filename.tar >> $filename.tar
mv $filename.tar $filename.tar.md5
MODEM
filename=modem
tar -H ustar -c NON-HLOS.bin modem.bin > $filename.tar
md5sum -t $filename.tar >> $filename.tar
mv $filename.tar $filename.tar.md5
FULL ODIN IMAGE
filename=I9505GUEUB_FULL_ROOTED
tar -H ustar -c boot.img recovery.img NON-HLOS.bin modem.bin system.img.ext4 > $filename.tar
md5sum -t $filename.tar >> $filename.tar
mv $filename.tar $filename.tar.md5
gzip $filename.tar.md5
Those are some of the common ones. What if I wanted a "semi-full rooted image"? For instance, without the modems? You just modify this line:
tar -H ustar -c boot.img recovery.img NON-HLOS.bin modem.bin system.img.ext4 > $filename.tar
so that it becomes:
tar -H ustar -c boot.img recovery.img system.img.ext4 > $filename.tar
Of if you don't want recovery, either, and just want boot and system:
tar -H ustar -c boot.img system.img.ext4 > $filename.tar
And the rest stays the same. I really hope this helps people. I will update this post to clarify anything that's confusing and will try to help people in this thread to create whatever they need. Again, you take responsibility for anything you create using these instructions and flash to your phone.
whats the command to create a system dump to an odin compatible system.img file? been a while. i forget
This is how I do it in my script:
adb shell "su -c 'cd /sdcard; dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/sdcard/system.img.ext4'"
adb pull /sdcard/system.img.ext4
adb shell rm /sdcard/system.img.ext4

I'm a relative noob and just learning as much as I can and this is alot of great info. I am able to pull system dump and pull recovery.img from my but when I create an odin flashable recovery image (for back-up purposes) it fails auth. Is there a way to pull a signed recovery image from system? Thanks.
No. When you dd extract a partition it adds padding to it which messes with the signature. I create a signed recovery img file by patching the boot img with the recovery-from-boot.p in the OTA update. That's a lot more involved than what's in this tutorial, however.

My initial results weren't very conclusive on that. I tried it with the NON-HLOS.bin file just to see if I could make it consistent with the one I create by patching, and the results were not good. There's no way to know exactly how long to make the cut. It seems like all you do is remove the trailing 00's when hexediting, but, I can tell you that's not enough to make it match. I've got more research to do on this as it would be extremely useful to be able to edit the dd extracted files to make them match the signed files. So far, that doesn't seem possible.

That's too bad, I was also hoping removing the trailing zeros would work. Can you point me to a tutorial, etc where i can learn how to patch using the OTA files? thanks again.

It's not quite as simple as that. There isn't a tutorial on it. I learned what I know from Matt Groff. It started with a thread here:
http://forum.xda-developers.com/showthread.php?t=1702233
But that thread isn't going to teach nearly enough to learn how to do this. It involves parsing the update scripts from the OTA to find the command they use to patch the actual partition and then converting that to a command to patch the file. So if you look at this command from install-recovery.sh:
applypatch EMMC:/dev/block/platform/msm_sdcc.1/by-name/boot:8036608:1ad324cf48a6e19fd402603477cd0ed8472ed863 EMMC:/dev/block/platform/msm_sdcc.1/by-name/recovery f4579fa7099942ec2f214cff81014b8e8b1a550f 8632576 1ad324cf48a6e19fd402603477cd0ed8472ed863:/system/recovery-from-boot.p
What that's doing is taking 8036608 bytes from the boot partition, ensuring it has a sha1 hash of 1ad324cf48a6e19fd402603477cd0ed8472ed863, patching it with the contents of the recovery-from-boot.p file, and then writing it to the recovery partition.
Each time an OTA comes out for our phones, I create signed recovery, modem, and non-hlos files using this process. Then I use the process outlined in this tutorial to create the ODIN tar md5 files that I post.

Success! Thanks so much, just created my first signed odin image!
Theres two more ways the get signed images. One is using dd if=of with the right bs and count. For example, I extracted the stock signed PIT file for the S4 using
Code:
su
dd if=/dev/block/mmcblk0 of=/sdcard/sch1545.pit bs=8 count=580 skip=2176
you can see the thread and md5 comparisonhere The other method is hexediting but it was easier on 4.2.2 but still very doable on 4.3. You have to know what signatures look like though. Hexediting can also be useful for manually extracting the zimage and ramdisk from a boot.img

I didn't. The first signed modem bin I made was done by looking at the size in the updater script and using cygwin to copy that many bytes to a new file. From then on I just patched the previous version's modem bin and NON-HLOS bin files.
