[Q] How to make an Odin Flashable Rom?

I was wondering if it is possible to make an Odin flashable ROM with only the CWM ROM? If not how could i make a Odin flashable ROM?

How to make an Odin flashable ROM
This needs a UNIX compatible OS - like Linux or Mac OS X.
On Windows, you can use "Cygwin".
Use the dd (datadump) command to make the .rfs files
Of course you need to connect your phone via USB and have ADB prepared on your computer.
# Get Root access first
Code:
su
# Do this first to mount the /system R/W
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# Dump the needed data / partitions to your /sdcard
Code:
dd if=/dev/block/stl9 of=/sdcard/factoryfs.rfs bs=4096
dd if=/dev/block/stl11 of=/sdcard/cache.rfs bs=4096
dd if=/dev/block/bml7 of=/sdcard/zImage bs=4096
dd if=/dev/block/bml12 of=/sdcard/modem.bin bs=4096
# Make the tar ball
Code:
tar -H ustar -c factoryfs.rfs cache.rfs modem.bin zImage > darky.tar
# MD5 it for a security check
Code:
md5sum –t darky.tar >> darky.tar
# Rename the tar file
Code:
mv darky.tar darky.tar.md5
Optional:
Make your own pit file
The pit file is used to set the partition layout (Partition Information Table).
# Dump the pit
Code:
dd if=/dev/block/bml2 of=/sdcard/darky.pit bs=4096
I hope I could help you with that

How doing this using phone runing cyanogenmod7?
Hey darky, how can i do this with a phone runing cyanogenmod 7? and after doing that, how can i install the rom with odin?
Thanks ;-)

I try to break down to understand from original firmware. I would like to discuss with anyone who expertise to solve understanding about odin system for GT-I9000. Anyone can give input in this thread to more understand newbie like me.
I not sure which the correct to follow to make own odin.

On-phone developing is the way to go. Start with a firmware from SamFirmwares.com. keep it safe. Do your modifications using the techniques I laid out here: http://forum.xda-developers.com/showthread.php?t=1030107 Then when you are finished, use the methods above.
Now, the reason you kept the SamFirmwares.com original firmware safe.... You'll need the partition information table PIT for an extra level of security when distributing your new ROM. For extra cool points, wrap it up in a Heimdall TAR.GZ firmware package, then make it a one-click with Heimdall One-Click (not yet finished).

btw.. to save space in the firmware package, you can omit the cache file, or clear your cache, then adb into your phone in recovery mode and grab it there... The cache file is regenerated when the user selects to clear cache.
The data partition is the temporary storage area for apps, also some apps default to the data area for storage.... It's also a good place to deploy binaries that you want to execute. It cannot be flashed by Odin protocol though.... It's the "extra" space on the disk left over after the partitioning.

Are you saying that I shall keep the original PIT file rather then dumped PIT file from above method? (dd if=/dev/block/bml2 of=/sdcard/odin/pit.pit bs=4096) ?

Or I should use it? before dumped the cache I shall do factory reset, clear dalvik cache and wipe battery stat?

My question is how do you do it? Do you create a .sh script with this and then just run it using script manager or do you have to run this script in recovery?
Thanks

you can do this without scipt it's easy, first,flash CF-Root kernel in recovery , then go to the app drawer then open the EXT4 app, then covert to ext4 this operation will take about 2-3 min in recovery,of course you need to have CWM4,at the end it wiil reboot you phone so enjoy it
Press the thanks butom if I helped

that ketut's script can only be use on odin files, cannot be use on already installed rom. btw cfroot ext4manager app should be able to do it directly from the phone.

ketut mentioned it is possible to do so on a pre-existing ROM but he doesn't recommend it haha.
Hmmm, i do not know why i don't have the ext4manager app even though i am on CF Root b82 kernel. Do i have to download the ext4manager app separately?
=====================================================================================================================
EDIT
I found the ext4manager on chainfire's post. Will install v1.3 and do the necessary file system conversion... and pray it works!
=========================================================
Update
It was my tardiness that led me to use chainfire's original ext4manager where i should have been using the version modified by ketut!
It worked like a breeze, install and the whole thing was done under a minute in recovery. I am very very happy with the results for i managed to gain about 400 points in Quadrant. Well, i couldn't get a OC kernel to work with my Stock ROM but this mod is ain't exactly that bad in coaxing out some performance.

did you use ext4manager from ketut's thread?
http://forum.xda-developers.com/attachment.php?attachmentid=714285&d=1315543936
ext4manager MUST detect your cf root kernel. if it does, it will automatically show the various partitions and the file system applicable.

thats just the kernel itself. scroll down and find CF Root S5830 ext4 v1.3 in the post by ketut if you want to. btw the link i posted earlier on is the actual download link for the ext4 manager that has been modified to work for S5830 by ketut.

Will this method work on all Galaxy ACE versions. My wife has the version for Latin America, same as the one sold in Brazil and Chile.
Not sure about the ROM version for this one though.

Does stock ROM kernel even support ext4???

could u help for installing CF Root ?
i have a stock rom 2.3.3
thanks in advance

[I9001] [SCRIPT] [ODIN] How to create an Odin package from a cwm-zip (or backup)

The script (see below) works as follows:
1. It takes the correct files from the BaseRom folder and copies them to the BuildOdin folder
2. If boot or recovery images exist in NewRom folder (extracted from the cwm zip) it will copy them to the BuildOdin folder too
3. It will create the system.img.ext4 file in the BuildOdin folder
4. It will copy the system folder in the NewRom folder to the system.img.ext4 file
5. It will tar and md5 the files in BuildOdin folder
So make sure you have:
1. The adsp.mbn, amss.mbn, cache.img.ext4 and preload.img.ext4 in the BaseRom folder
2. The boot.img and recovery.img in the NewRom folder (or BaseRom)
3. The system folder in the NewRom folder
And run the script
Code:
#!/bin/sh
echo 'Requesting password to allow running as root...'
sudo echo 'Thanks :)!'
# Make folder
if [ ! -d "BuildOdin" ]
then
mkdir BuildOdin
fi
# Copy BaseRom files
cp BaseRom/adsp.mbn BuildOdin/adsp.mbn
cp BaseRom/amss.mbn BuildOdin/amss.mbn
cp BaseRom/cache.img.ext4 BuildOdin/cache.img.ext4
cp BaseRom/preload.img.ext4 BuildOdin/preload.img.ext4
# Copy boot image
if [ -s NewRom/boot.img ]
then
cp NewRom/boot.img BuildOdin/boot.img
else
cp BaseRom/boot.img BuildOdin/boot.img
fi
# Copy recovery image
if [ -s NewRom/recovery.img ]
then
cp NewRom/recovery.img BuildOdin/recovery.img
else
cp BaseRom/recovery.img BuildOdin/recovery.img
fi
# Create system image
mysyssize=`du -s -h NewRom/system | awk 'BEGIN{FS="[M]"} {print $1}'`
mysyssizeincreased=$((mysyssize+50))
echo 'Filesize will be' $mysyssizeincreased 'MB'
echo 'dd empty image...'
dd if=/dev/zero of=BuildOdin/system.img.ext4 bs=1M count=$mysyssizeincreased >&- 2>&-
echo 'make it ext4...'
mke2fs -F -T ext4 BuildOdin/system.img.ext4 >&- 2>&-
echo 'mounting...'
sudo mount -t ext4 -o loop BuildOdin/system.img.ext4 /mnt >&- 2>&-
echo 'copying system...'
cp NewRom/system/* /mnt -rp
sync
echo 'unmounting...'
sudo umount /mnt
# Create Odin and Odin MD5 files
cd BuildOdin
echo 'tarring...'
tar -cf MyOdinpack.tar adsp.mbn amss.mbn boot.img cache.img.ext4 preload.img.ext4 recovery.img system.img.ext4
echo 'copying...'
cp MyOdinpack.tar MyOdinpack.tar.md5
echo 'md5sum...'
md5sum -t MyOdinpack.tar>>MyOdinpack.tar.md5
echo 'done!'
It looks like it works. I do have some stuff I am wondering about:
1. I have added 50 MB to the filesize, with 30 MB additional I still got a not enough diskspace error. Wondering why...
2. Will it work this way? When looking at a cwm-zip it does contain a system folder but they also contain some other stuff... who knows... anyone care to test?
Well, looks like it's not all that easy. The script works, it creates a file with the exact same files as the one created with dd on the device, but for some reason when using it in Odin, it doesn't work...
Creating the Odin package is superfast now, but will still require some more testing. I guess I should do it with a ROM that I have done before... but too lazy atm...
Btw, this way I could create an Odin package from a CWM backup too If ever needed, just let me know
Regards,
Nika.

you could try making system.img file, then rename it to system.img.ext4. Sound foolish probably, but sometimes these double extensions are just added as an indicator. in this case for the system to look up what partition type to take. (I could be horribly wrong tho. But there are like 0 tools on internet for an ext4 maker so not many options available)

Maybe create an empty ext4 image on PC, mount loopback in cwm and copy files to it.
Sent from my GT-I9001 using XDA App

Create image on your phone using busybox
Edit: I updated the script.
I played a bit with the busybox:
my working dir is /sdcard/external_sd/imgtest!
DD a file of ~300MB
busybox dd if=/dev/zero of=myimg.img bs=1M count=300
Create a ext4 filesystem on this img
busybox mke2fs -F -T ext4 -L Image myimg.img
Create a new /dev node, named "loop99", type "block device" (b), and some major and minor number
busybox mknod /dev/block/loop99 b 7 99
Prepare your new loop device with an img file (delete is with losetup -d /dev/block/loop99)
busybox losetup /dev/block/loop99 /sdcard/external_sd/imgtest/myimg.img
Mount it finally
busybox mount /dev/block/loop99 /sdcard/external_sd/imgtest/mymnt
Now you may copy what you want, say /system, to this img.
And unmount it (make sure it's not in use anymore)
busybox umount /dev/block/loop99
Maybe invoke some commands to check the size of /system? A quick one liner would be
busybox df /system -h | grep /system | awk 'BEGIN{FS="[M]"} {print $2}' | awk 'BEGIN{FS="[.]"} {print $1}'
Could be part of the shell script, saved to a variable and increased by some MB just to make sure^^
A very quick and dirty script:
#!/bin/sh
mysyssize=`busybox df /system -h | grep /system | awk 'BEGIN{FS="[M]"} {print $2}' | awk 'BEGIN{FS="[.]"} {print $1}'`
mysyssizeincreased=$((mysyssize+20))
mkdir /sdcard/external_sd/myimages
mkdir /sdcard/mnt/
mkdir /sdcard/mnt/mymnt
cd /sdcard/external_sd/myimages
echo Filesize is $mysyssizeincreased
echo Now dd a new image for your folder
echo dd in progress...
busybox dd if=/dev/zero of=myimgfile.img bs=1M count=$mysyssizeincreased
echo mke2fs with type ext4 on your file...
busybox mke2fs -F -T ext4 -L Imagename myimgfile.img
echo create new dev-node...
busybox mknod /dev/block/loop99 b 7 99
echo apply loopback setup on this node...
busybox losetup /dev/block/loop99 /sdcard/external_sd/myimages/myimgfile.img
echo mounting new image...
busybox mount /dev/block/loop99 /sdcard/mnt/mymnt
echo done!
echo
echo now copy your system files over preserving permissions...
cp /system/* /sdcard/mnt/mymnt -rp
sync
busybox umount /sdcard/mnt/mymnt
losetup -d /dev/block/loop99
rm /dev/block/loop99

Save as a .sh script and execute it. I tried with some ssh server on phone and shell on my PC.
Worked fine, but to be sure a test with a restore would be needed, so treat it as highly experimental.

Very nice, much appreciated!!! Will try (convert) them on ubuntu one of these days as I'd prefer to do the job on a dual-cpu machine

Well then you should skip the steps with mknod and so on. Mount is much more powerful there, so you should be able to do it with these commands:
dd if=/dev/zero of=/tmp/image bs=1M count=300
mkfs.ext4 /tmp/image
mount -o loop /tmp/image /mnt

Hmmm... getting a "is not a block special device" message when ext4-ing in linux. Either the command file is incorrect, or I need to suppress that message somehow... more news soon

Okay!! Here's the first version of the script:
Code:
#!/bin/sh
echo 'Requesting password to allow running as root...'
sudo echo 'Thanks :)!'
# Make folder
if [ ! -d "BuildOdin" ]
then
mkdir BuildOdin
fi
# Copy BaseRom files
cp BaseRom/adsp.mbn BuildOdin/adsp.mbn
cp BaseRom/amss.mbn BuildOdin/amss.mbn
cp BaseRom/cache.img.ext4 BuildOdin/cache.img.ext4
cp BaseRom/preload.img.ext4 BuildOdin/preload.img.ext4
# Copy boot image
if [ -s NewRom/boot.img ]
then
cp NewRom/boot.img BuildOdin/boot.img
else
cp BaseRom/boot.img BuildOdin/boot.img
fi
# Copy recovery image
if [ -s NewRom/recovery.img ]
then
cp NewRom/recovery.img BuildOdin/recovery.img
else
cp BaseRom/recovery.img BuildOdin/recovery.img
fi
# Create system image
mysyssize=`du -s -h NewRom/system | awk 'BEGIN{FS="[M]"} {print $1}'`
mysyssizeincreased=$((mysyssize+50))
echo 'Filesize will be' $mysyssizeincreased 'MB'
echo 'dd empty image...'
dd if=/dev/zero of=BuildOdin/system.img.ext4 bs=1M count=$mysyssizeincreased >&- 2>&-
echo 'make it ext4...'
mke2fs -F -T ext4 BuildOdin/system.img.ext4 >&- 2>&-
echo 'mounting...'
sudo mount -t ext4 -o loop BuildOdin/system.img.ext4 /mnt >&- 2>&-
echo 'copying system...'
cp NewRom/system/* /mnt -rp
sync
echo 'unmounting...'
sudo umount /mnt
# Create Odin and Odin MD5 files
cd BuildOdin
echo 'tarring...'
tar -cf MyOdinpack.tar adsp.mbn amss.mbn boot.img cache.img.ext4 preload.img.ext4 recovery.img system.img.ext4
echo 'copying...'
cp MyOdinpack.tar MyOdinpack.tar.md5
echo 'md5sum...'
md5sum -t MyOdinpack.tar>>MyOdinpack.tar.md5
echo 'done!'
It looks like it works. I do have some stuff I am wondering about:
1. I have added 50 MB to the filesize, with 30 MB additional I still got a not enough diskspace error. Wondering why...
2. Will it work this way? When looking at a cwm-zip it does contain a system folder but they also contain some other stuff... who knows... anyone care to test?
The script works as follows:
1. It takes the correct files from the BaseRom folder and copies them to the BuildOdin folder
2. If boot or recovery images exist in NewRom folder (extracted from the cwm zip) it will copy them to the BuildOdin folder too
3. It will create the system.img.ext4 file in the BuildOdin folder
4. It will copy the system folder in the NewRom folder to the system.img.ext4 file
5. It will tar and md5 the files in BuildOdin folder
So make sure you have:
1. The adsp.mbn, amss.mbn, cache.img.ext4 and preload.img.ext4 in the BaseRom folder
2. The boot.img and recovery.img in the NewRom folder (or BaseRom)
3. The system folder in the NewRom folder
And run the script

Well, looks like it's not all that easy. The script works, it creates a file with the exact same files as the one created with dd on the device, but for some reason when using it in Odin, it doesn't work...
Creating the Odin package is superfast now, but will still require some more testing. I guess I should do it with a ROM that I have done before... but too lazy atm...
Btw, this way I could create an Odin package from a CWM backup too If ever needed, just let me know

I've been searching the forums for a general way to make Odin-flashable ROMs from CWM backups. I'm particularly interested in doing this for Samsung Galaxy 10.1/8.9/7.7 tabs (Honeycomb). Many tutorials use ADB and datadumps, which is fine but is very device-specific, and I haven't found one for the Honeycomb Galaxy Tabs. Using CWM backups seem cleanest and least-device specific way.
So I *AM* interested in how you would start with a full CWM backup, and (not using any base ROMs) get an Odin-flashable .tar.md5 file.

hmmmm bht ho gya hia yaar

Hi kblam,
Well... it's still a work in progress. Not sure why it doesn't work at the moment, but here's my current script:
Code:
#!/bin/sh
echo 'Requesting password to allow running as root...'
sudo echo 'Thanks :)!'
# Make folder

then
mkdir BuildOdin

# Copy boot image
if [ -s NewRom/boot.img ]
then
cp NewRom/boot.img BuildOdin/boot.img
else
cp BaseRom/boot.img BuildOdin/boot.img
fi
# Copy recovery image
if [ -s NewRom/recovery.img ]
then
cp NewRom/recovery.img BuildOdin/recovery.img
else
cp BaseRom/recovery.img BuildOdin/recovery.img
fi
# Create system image
mysyssize=`du -s -h NewRom/system | awk 'BEGIN{FS="[M]"} {print $1}'`
mysyssizeincreased=$((mysyssize+50))
echo 'Filesize will be' $mysyssizeincreased 'MB'
echo 'dd empty image...'

echo 'mounting...'
sudo mount -t ext4 -o loop BuildOdin/system.img.ext4 /mnt >&- 2>&-
echo 'copying system...'
cp NewRom/system/* /mnt -rp
sync
echo 'unmounting...'
sudo umount /mnt
# Create Odin and Odin MD5 files
cd BuildOdin
echo 'tarring...'
tar -cf MyOdinpack.tar adsp.mbn amss.mbn boot.img cache.img.ext4 preload.img.ext4 recovery.img system.img.ext4
echo 'copying...'
cp MyOdinpack.tar MyOdinpack.tar.md5
echo 'md5sum...'
md5sum -t MyOdinpack.tar>>MyOdinpack.tar.md5
echo 'done!'
Taking out all unnessesary comments and commands, what it's supposed to do is the following:
1. First copy the files from the BaseRom (the ones you usually do not extract either):
Code:
cp BaseRom/adsp.mbn BuildOdin/adsp.mbn
cp BaseRom/amss.mbn BuildOdin/amss.mbn
cp BaseRom/cache.img.ext4 BuildOdin/cache.img.ext4
cp BaseRom/preload.img.ext4 BuildOdin/preload.img.ext4
2. Then take the boot and recovery from another folder as they usually need to be based on another kernel (f/e Skyhigh kernel ) and/or recovery (f/e CWM/Faemod):
Code:
cp NewRom/boot.img BuildOdin/boot.img
cp NewRom/recovery.img BuildOdin/recovery.img
3. Take the size of the new image (based on the system folder size + 50):
Code:
mysyssize=`du -s -h NewRom/system | awk 'BEGIN{FS="[M]"} {print $1}'`
mysyssizeincreased=$((mysyssize+50))
4. Create an empty system image
Code:
dd if=/dev/zero of=BuildOdin/system.img.ext4 bs=1M count=$mysyssizeincreased >&- 2>&-
5. Convert it to ext4
Code:
mke2fs -F -T ext4 BuildOdin/system.img.ext4 >&- 2>&-
6. Mount it and copy the new system files (can be unzipped from the cwm-zip) and unmount
Code:
sudo mount -t ext4 -o loop BuildOdin/system.img.ext4 /mnt >&- 2>&-
cp NewRom/system/* /mnt -rp
sync
sudo umount /mnt
7. The rest is same to building other md5 odin files. Combine them with tar and calculate and add the md5 sum
Code:
tar -cf MyOdinpack.tar adsp.mbn amss.mbn boot.img cache.img.ext4 preload.img.ext4 recovery.img system.img.ext4
cp MyOdinpack.tar MyOdinpack.tar.md5
md5sum -t MyOdinpack.tar>>MyOdinpack.tar.md5
As mentioned - I am not sure why the system image created this way does not work yet (I only tested it once) - maybe someone else is willing to test?

Nika.

[Q]Making Odin ROM

Hello,
First of all Im posting this after a long search so plz bear with me.
Ive read most of the guides but I want to understand it a bit more,and just to be clear Im not asking to explain every thing(although it could be nice ^^) but point me to some reading material.
Ill use #Darkyy guide for example : http://forum.xda-developers.com/showthread.php?t=960946
*I hope ur ok with this (I couldn't post on ur thread cuz im anoob here..)
Code:
mount -o remount,rw /dev/block/stl9 /system
dd if=/dev/block/stl9 of=/sdcard/factoryfs.rfs bs=4096
dd if=/dev/block/stl11 of=/sdcard/cache.rfs bs=4096
dd if=/dev/block/bml7 of=/sdcard/zImage bs=4096
dd if=/dev/block/bml12 of=/sdcard/modem.bin bs=4096
tar -H ustar -c factoryfs.rfs cache.rfs modem.bin zImage > darky.tar
md5sum –t darky.tar >> darky.tar
mv darky.tar darky.tar.md5
dd if=/dev/block/bml2 of=/sdcard/darky.pit bs=4096
Q-I want to understand what each command is for?
Q-How do I know the location and roll of every file (so this can be use on different devices)? *Edit A-I found that the files are in /dev/block wich brings me to the next question:
Q-How can I know With file is witch ? (right now I cant find the bml7 partition(kernel\zimage).
Q- Is there a guide about Odin- the roll of every file, what it contains, where its on the device?
*** Plz help me fully understand the process and not just coping it... ***
Thx for every reply and information
***Edit***
After reading http://forum.xda-developers.com/showthread.php?t=1171211&highlight=make+odin
I got to this point:
I backed up the factory and the cache partition, but I cant find the kernal (zimage)partition (bml7).
For some unknown reason my 'mount' chart is as follows:

How can I see other partitions ?
Is there any way to know witch is witch in the /dev/block directory?
Plz Help me ..
**Edit**
I used "ls command" (Astor browser actually to brows /dev/block and I cant pinpoint the kernel file)
I tried to make a tar file but I end up with " Read-only file system" Error.

The "read only" message is because you're on your root folder. Move up to your sd card:
Code:
cd /sdcard/test/
tar -c cache.rfs > CSC.tar

Can't find zImage mount point in Slim Jelly Bean (Android 4.1)
I think I have the same situation as yours. I tried everything, but couldn't find the /dev/block device associated to zImage...
