How to make an Odin flashable ROM
This is just a small guide I want to share with anyone who's interested in the commands I personally use. Feel free to correct me or give better commands / instructions.
@Moderators:
If this thread is in the wrong section or already present at XDA, PM me.
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
(thanks to scheichuwe for the simplified command)
Code:
mount -o remount,rw /dev/block/stl9 /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
- darkyy.
Nice
Yeah first
Oh and one more thing:
If someone is gonna rate this thread 1 star, please explain here why.
So this means I can make an Odin rom of my current installed config? Or am I missing something?
If you then flash your tar + pit, you have your kernel and rom restored? This would be an awesome way to backup a good config, no?

Exactly - these commands will dump the data directly from your current phone.
And yes, you'll have a 1 to 1 Backup.
That is actually VERY useful! I'm constantly switching between a modded Insanity and CM7, and constantly reverting to stock, flashing custom kernels and flashing nandroids is getting quite annoying now.
Don't have access to a linux machine now, I'll try this asap, thanks!
Wow, dasch mal nützlich ville dank^^
Neat. Thank you!

Well you can install cygwin, just remember to install bash terminal when cygwin setup is running.

No:
The instructions from drakyy create a flashable ROM from the phone.
The Application from bohdans creates a flashable ROM from files on your computer

I have a problem. When tryign to create the tar-file i get:
cannot create jesper.tar: read-only file system.
What to do?
Does this also work when the partitions are NOT RFS.
Like all in ext4?
Will Odin be able to flash that image?
I somehow doubt it...

Good question..... I'd like to know this too..
Although even if having to disable lag fix to create it the apply again after flashing is still a quicker way to toggle between your current rom and cm7..
Neat Darky

Does anyone know what format is used to pack the stock system.img and userdata.img images for the Galaxy Nexus? I'm trying to extract the files from these images but not sure how to do so. So far I've tried unyaffs but it's segfaulting on the images, so I suppose these images aren't yaffs.
Try ext4 if unyaffs doesn't work

Ah, so it's a special sparse ext4 image that needs to be converted to a normal ext4 image using one of the tools in AOSP.

This worked.
For anyone that doesn't want to root the hard way crossix has come up with a double click root for Windows forum.xda-developers.com/showpost.php?p=23052186&postcount=105
Update 2/26/12
/system can now be mounted writable see the bottom of this post.
So the old Honeycomb exploit has now been patched in ICS. But there was an exploit found in the newer ICS kernels. Written by saurik,: called mempodroid
There is an offset needed as an argument to the binary, for the a100 we'll use what has worked for the a200 as noted in sauriks github linked above.
The issue with this is mounting /system as writable. I'm not sure if it's something in ICS, but it appears to be write protected. As noted here and here we will loop mount the system partition.
The tools needed are:
1. mempodroid under Usage Instructions, download pre-compiled
2. busybox 1.20 snapshot 3-10-12
3. su the latest from androidsu.com, extract from system/bin
4. mount.txt script
After downloading and extracting place them all in a folder called tools.
This must be done with adb. Issue the following from cmd or a terminal:
Code:
$ adb shell mkdir /data/local/tools
$ adb push tools /data/local/tools ; adb shell
$ cd /data/local ; chmod 755 tools/*
$ cd tools ; ./mempodroid 0xd9f0 0xaf47 sh
If all went well you should be at a hash # prompt. This is temp root.
mount /system rw the new way:
Code:
# PATH=$PWD:$PATH
# sh mount.txt -o remount,rw /system
Copy su and busybox to /system
Code:
# ./busybox cp busybox /system/xbin; ./busybox cp su /system/xbin/
# chmod 6755 /system/xbin/su
Install busybox
Code:
# cd /system/xbin
# for i in $(busybox --list); do ln -s busybox $i; done; sync
Copy the mount script
If busybox is updated this step must be run again
Code:
# cp /data/local/tools/mount.txt /system/bin/mount
# cp /data/local/tools/mount.txt /system/xbin/mount
Done your a100 should be rooted
the old way:
Now lets loop mount /system
Code:
[b]This is no longer needed[/b]
# ./busybox losetup -o $((512 * 51200)) /dev/block/loop7 /dev/block/mmcblk0
Code:
# ./busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
# mkdir loop ; mount -t ext4 /dev/block/loop7 loop
Copy su and busybox to the new mount point.
Code:
# ./busybox cp su loop/xbin/ ; ./busybox cp busybox loop/xbin/
# chmod 6755 loop/xbin/su ; sync
If it worked your a100 is fully rooted. Make sure to install SuperUser from the Market.
Either get busybox installer from the market, and install it to /data/local/tools/loop/xbin
Or:
Code:
# cd loop/xbin
# for i in $(busybox --list); do ln -s busybox $i; done; sync
The mount point won't survive a reboot so in order to write to /system again run:
Code:
# busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
# mount -t ext4 /dev/block/loop7 /data/local/tools/loop
[update 2/26/12]
To mount /system as writable do the following from adb. We'll just make a directory called /data/loop for easy access.
Code:
$ adb shell
$ su
# stop
[b]your screen will go black[/b]
# mkdir /data/loop
[b]skip this if the loop is already set up
# busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3[/b]
# mount -t ext4 /dev/block/loop7 /data/loop
# mount -o bind /data/loop /system
# start
You can write to /system with any app but /system can't be remounted ro then back to rw.
This can be added to /etc/install-recovery.sh to make it permanent
Code:
busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
mount /dev/block/loop7 /data/loop
mount -o bind /data/loop /system
Thanks to crossix as the first to get temp root, and Icewyng for pointing out the exploit and helping with the magic number.
Ill be testing this when I get home, if it works Ill attempt to write a 1 command script to do it.

OK...
Testing this out and found there were a couple of bugs.
You didn't have a "loop" folder created so I made one in the "tools" folder.
and, when mounting, you need to specify -t ext4.
Here are the revised commands for # mount /dev/block/loop7 loop
mkdir loop;mount -t ext4 /dev/block/loop7 /data/local/tools/loop
I noticed that the files /data/local/tools/loop/xbin/su and /data/local/tools/loop/xbin/busybox don't exist on /system/xbin until after a restart.
Finally, the busybox we are using to install doesn't seem to make all of the links to all of the nice commands we are used to, so things like grep, cp, etc... they won't work. I'm trying to figure out how to re-run the GUI busybox installer and point it to the loop folder, but haven't had much success.

You beat me to the punch... was about to point it out.
Not sure what version of busybox this is but I will try with 1.19.2 and see how it goes.
Edit: Got root! It works great... for Busybox, use Busybox Installer to be able to get the latest version (1.19.4) I confirm that system is R/O for now.

I did have some typos, think it's right now. That is an old busybox, it was just a quick find and it includes losetup but it's not one to use full time. Maybe sync is needed at the end so files are written properly. I didn't have to use -t ext4 with HC, but Ill add it to the OP
[edit] you have to use "busybox cp or busybox grep" I didn't include a way to add all the symlinks. Wow I have typos everywhere it's the end of the day for me, working nights.
Ok ... Got root!
Titanium works, Busybox Installer works, Superuser works, Root Explorer works...
Only thing is that System is R/O but we will work on it.
Waiting for a R/W system...and then, no one will stop my update

At what point, need some more details.
The tools folder gets pushed (the 3 files are copied) but then it says there is no such folder.
edit: never mind - i created the folder manually and pushed the files into the folder
edit2: rooted - thakns guys
Brilliat work, will try this later (need to get the sdk all set up again, I've been distro swapping). Got a pool match tonight too, so will try as soon as I can, will give whatever feedback I can later.

I forgot adb can't push a whole directory, it instead only copies the files within the directory.
wait how is it rooted if it's r/o I thought point of root was to make the file system r/w... er is root just allowing you to view all directories? Sorry for a noobish question, but you gotta start somewhere right?

Well I think if we have su working we will be able to mount /system rw in some way if not directly. I cant imagine not being able to.
In any case though being able to write to /data as root is very useful. Example: Hulu flash fix.
You can't view /data if you're not root. That's one thig. Also, other functions may require root, like advanced networking things, etc.
I agree, not being able to write to /system is a major inconvenience, but most of the root programs will still work, as long as you're not writing to /system.
Since this is a temp root, does it mean that I will have to reroot every time I reboot? Will apps like Adfree work on this?
better yet is there a way we can do this solely on the tab? im away for work for another 4 weeks and only have my cell and a100 with me :-(

The first line may produce
losetup: /dev/block/loop7: No such device or address
If it's not looped
After you are rooted the above can be run without adb from a terminal as su.
The mount point can be anywhere ex. /sdcard/loop instead of /data/local/tools/loop
Hello there,
does anyone know how to mount the galaxy s4 as writeable via adb?

omg no no no no.
if you are talking about trying to use "adb push <name of file> <destination file>"
Then you must use "adb remount" if it fails, you are not on an insecure kernel. Thus your only option is to push to the sdcard then use "adb shell" and navigate to your sd card and use "cp <name of file on sdcard> <destination file location>"
as for the commands, it is NOT what you have posted. it is simply
mount -o rw,remount /system
nothing else is needed. You will seriously mess something up if you try mounting it as yaffs2 considering we use ext4 now. FYI, the above command can only be entered AFTER first entering "adb shell" which gives you a command line on the device to execute commands.

Then you need to use
adb shell mount -o rw,remount /system
thats it. To uninstall apks, use:
adb uninstall <package name>
And you are getting a read only system error because you are trying to create that "file.txt" file onto your "root" directory.
do this:
adb shell cd /data/media/0
then try to do your list packages.
Just got a used Tab Pro 8.4. I've rooted it and now am interested in debloating it. I've always done this manually with adb on my previous devices using a command I always assumed was specific to that particular device (ie. mount -o remount,rw /dev/block/mmcblk0p20 /system for a Note 3) .
I haven't found any references in the Tab Pro forum to the mount command for writing to the system partition. When I list the mount points with the mount command inside the adb shell I see this:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0
So would the command really be mount -o remount,rw /dev/block/platform/msm_sdcc.1/by-name/system /system ? I have seen references elsewhere to a generic "mount -o rw,remount /system" command for Android devices in general.
I'm sure there are pre-built tools that would let me do some debloating without worrying my little head about what's going on under the hood. But please humor me. I enjoy learning the details of how these boxes operate by working with them manually. Any help here will be appreciated. Thanks.
So you are not going to flash the ROM, you could also try Gates Debloater tool. I used on my Note 4 all the time, may Tab I just flashed to a new ROM though.

All you should need to do is
# mount -o remount,rw /system
It's in fstab, so you don't need the block device.
When done just issue a sync and reboot.
