[Samsung Galaxy Gio GT-S5660][Tutorial] Export ROM for use in Odin

---

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

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

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%

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

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

8. Add md5 hash to our tarball for security and integrity checks

md5sum -t thisismyrom.tar >> thisismyrom.tar

9. Renaming our tarball with md5 extension:

mv thisismyrom.tar thisismyrom.tar.md5

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.

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
