HELP!!!! Firmware troubles

Hi

I'm hoping someone can point me in the right direction as i'm at the end of my tether.

I have the bog standard S3 GT-i9300 Nordic (purchased in Sweden)

Trying to flash back to stock firmware I downloaded the I9300XXBLH3_I9300NEEBLH2_I9300XXLH1_HOME.tar.md5 firmware (4.0.4) Downloaded from Sammobile

Flashed with odin

Restart loop - so I went into recovery mode, cleared cache and reset, restarted fine....

Upon restart phone downloads firmware update.... Updates

The in settings - about device i have Android version 4.1.1 - Baseband version I9300XXDLID Build number JRO03c.I9300XXDLJ2 (French??)

Kernal version 3.0.31 -319653

Although this firmware lets me use my Telia Sim card it will not let me use my 02 simcard - Now I know the phone was originaly unbranded & unlocked

I then went into Kies and restored there, entering the phones serial number etc.

The phone was then updated to 4.1.2 (Russia) I9300XXELL4

I have no idea what I have done for the phone not to restore back to stock official Nordic firmware that is unlocked.....

Any help is very much gratefully received.
