Thanks a lot to hdblog.it, successfully received my prize for the Samsung Galaxy's root contest !



DEPRECIATED !!!! See : [Solo gli utenti registrati al Forum possono vedere i link. ]










UPDATE:

- 30/07/09 : recovery image added





Screen :




This is the first hack of the Samsung Galaxy. This is a first step, which provides, via the "su", or with adb, root access to the terminal.

The method used is the modification of the boot image, and injecting it through the tool of Samsung "New PC Studio".

When root whith adb, I used the method of Dream and the Magic to have a root shell (creating a root shell from sh shell, and adding the setuid bit).



WARNING: THIS METHOD CAN BE DANGEROUSE. DO NOTHING IF YOU DO NOT KNOW WHAT YOU DO.
I OR HDBLOG CAN'T BE RESPONSIBLE IF YOU TRANSFORM YOUR GALAXY LIKE A BRICK.




BACKUP

Before flash your galaxy, it is strongly recommended to backup it with nandroid :

1) flash your recovery partition with the recovery image (check at the end of this post)
2) boot in recovery mode
3) execute nandroid






A) If you don't have modified update already for your country and operator (see the list of available updates at the end of post), it will need to create a modifier update file by your own.


1) Get the modified boot image for your update at the bottom of post. Copy it on a linux machine (virtual or not).

2) Install the software "Samsung PC Studio New" and run it (see end of post for links)

3) Connect your phone. Your system install the drivers, and "New PC Studio" recognizes the Galaxy

4.a) If your phone is not up to date : the software will notify you. Run the updater.
4.b) If your phone is already updated, then "NEw PC Studio" does not force the update. Fortunately, it is still possible to manually run "NPSMitsBinaryUpgrade.exe" which is in the installation directory of New PC Studio (C: \ Program Files \ Samsung \ Samsung PC Studio New \) to force the update

5) The application launches and downloads the latest update, decrypts, and decompresses. Then the application tells you that all is well and that the update actually can begin, do not click on "next"!

6) The update file is located into the directory "C: \ Documents and Settings \ YOUR_USERNAME \ Application Data \ Samsung \ New PC Studio \ LinuxMitsBU \ 6 \ GT-i7500I7500BOGIG8I7500XXIG8I7500XXIG8_500 \". Copy the tar file on a machine (physical or virtual) under linux.

7) Open the file update under linux. Several files are present. Replace the file named "kernel" by the modified boot image in the pack.

8) Check the rights of the kernel file in the archive (rw-r-r root:root)

9) Transfer the update file under windows

9) Copy the new modifier update file to replace the old, in "C: \ Documents and Settings \ YOUR_USERNAME \ Application Data \ Samsung \ New PC Studio \ LinuxMitsBU \ 6 \ GT-i7500I7500BOGIG8I7500XXIG8I7500XXIG8_500 \

10) You can then continue the update process, the Galaxy will be flashed with the modified update file






If you have a modified update file for your country and operator (see the list of available updates at the end of post):


1) Install the software "Samsung PC Studio New" and run it (see end of post for links)

2) Connect your phone. Your system install the drivers, and "New PC Studio" recognizes the Galaxy

3.a) If your phone is not up to date : the software will notify you. Run the updater.
3.b) If your phone is already updated, then "NEw PC Studio" does not force the update. Fortunately, it is still possible to manually run "NPSMitsBinaryUpgrade.exe" which is in the installation directory of New PC Studio (C: \ Program Files \ Samsung \ Samsung PC Studio New \) to force the update

5) Copy the new modifier update file to replace the old, in "C: \ Documents and Settings \ YOUR_USERNAME \ Application Data \ Samsung \ New PC Studio \ LinuxMitsBU \ 6 \ GT-i7500I7500BOGIG8I7500XXIG8I7500XXIG8_500 \

6) You can then continue the update process, the Galaxy will be flashed with the modified update file





After the reboot of the Galaxy, if you run adb, you are root!


The official version of adb does not work properly with the Samsung Galaxy, see the links below to download a modified version for linux.





Now you probably want to be able to be root directly on the Galaxy, not only with adb. The first step used here is the method already used for the Dream and the Magic to have a super-user terminal:


Connect to the Galaxy with adb. You are root. Execute the following commands:

1) mount-o remount, rw-t yaffs2 / dev/block/mtdblock3 / system
2) cd system/bin
3) cat sh > su
4) chmod 4755 su
5) reboot


On the Market, install the application nammed "ConnectBot. Launch it, you can connect locally. You are somply user. Typing "su", you are root. Enjoy

Hmm, the kernel file in the .tar-archive has the user/group set as drakaz and not root
will it work anyway?

Sorry for this bug, the fix is uploading, please wait ;)

so... with this root - is it possible to pull a full firmware backup or whatnot via Nandroid?
and what would we need for fastboot to work?

Before now, not, because there isn't recovery image compatible with the galaxy. I've created just now
