[HOWTO] Universal CSC & recover product code [ANY ROM] (I5801 supported)

Before anything, I hope you have an /efs folder backup, you should have done it even before flashing!

NOTICE: This method does a reset, your SGS only maintains your personal files (sdcard & external sdcard). I'm not responsible at all for any problem that you get for following this procedure.

This procedure must bee done after flashing and before installing "anything" ("only" root and a program like Root Explorer are allowed :P). If you do this after you'll likely have problems!

You need root access so this can work! You may do this with commands via ADB or terminal, or else in a easy way with a program like Root Explorer (notice this is a paid app).

MANUAL METHOD:

1. First, get the right folder for your country (available at the bottom of this topic or else ask me) and copy it to /system/csc.*
2. After, open an ADB shell, and use the following command:

am start -a android.intent.action.MAIN -n com.android.Preconfig/com.android.Preconfig.Preconfig

3. After this, select on your SGS, your CSC country code. Then it'll reboot, you'll have to do the initial configuration, and it's done!

"AUTOMATIC" METHOD (firmwares dated to september (or newer)): (Thanks for Richthofen, for this info!)

1. First, get the right folder for your country (available at the bottom of this topic or else ask me) and copy it to /system/csc.*
2. After, check your IMEI with this code on the dialer, *#06#, and save it as you'll need.
3. Then, type on the dialer, *#272*???????????????# (??????????????? it's your IMEI, it must have 15 digits), after you can chose your CSC, then it'll reboot (it may take some time, you'll see bootloader applying the changes), you'll have to do the initial configuration and it's done!

For your country you'll need a specific folder. If you don't find it were, give me an CSC file for your country (any firmware version, I just need the file "cache.rfs" or the "CSC_I9000------.tar.md5") and I will make the folder for your country available.


* If you're on JPK (probably on every new version of Froyo), you'll need the following commands to be able to copy the CSC folder to the /system/csc.

Code:

adb shell
su
busybox mount -o remount,rw /system

This process is fully functional, it changes your CSC and recover your original product code! (to have your product code recovered your nv_data.bak should be compatible with the CSC you apply)

PS: You can check your product code with SGS ToolBox.
PS2: I did some search and didn't see this method posted were on XDA. If I'm wrong, sorry!

Download the pack, put it on sdcard, go to ClockworkMod Recovery mode, choose "install zip from sdcard" and install the pack. Then reboot and follow steps 2 and 3 of "Automatic method" explained above! (check your CSC code on the list bellow)

I've to test this some more time and I also expect some feedback from you After that I'll turn this pack the most "universal" possible.


Thanks to on.one on the info on this process.
