How to Un-root samsung galaxy SL I9003

[iamanoopk]

Hi,
I have rooted my samsung galaxy SL I9003 with ICS update(4.0.4). the version seems to be unstable and my phone sometimes hangs up on calls or taking an application. My cynaogen mode version is EHNDROIX 12.9.3 Based on 9.0

I would like to un-root my phone back to official gingerbird update. Please help.

I would like to know the procedures to do this.

Thanks in advance

I would try another CM build instead of going back to stock. Even CM7 would be an improvement.
