how to find original (stock) ROM

I messed up a lot with my SGS, tried many ROMs as a nubi, now I need to send it to the service, i don’t know the original (stock) ROM,
and what are the steps to reinstall it and update it from kies.
I bought it from, Sweden its XEE,

Can anyone help please?

 

Can you please define "I messed up a lot with my SGS" by what cause are you sending it to service?

If you currently have XEE, an Odin flash of the JM2 in my guide should do the trick.

That will restore your phone to an old Eclair 2.1 XEE, which you can send to the service center, or update it to the latest version via Kies.

 

Thanks i checked that before, th problem i don't know wich to choose,
i installed XWJM8 and when i go to the recovery a red line says:
multicsc: can not acces to /system/csc/xee/system/

 

Tack för din guide elof, läste den förut. Väldigt bra tips och information.
