Root your Samsung galaxy SL i9003

Required tool and CFROOT: 

1 -> CFROOT based on your ROM download from here

CF-Root for most I9003 firmwares.

All the credit goes to Skin's cf-root and his great help in resolving issues. 
UtterChaos Kernel Credit goes to DoomLord and Napster. 
Cwm 5.0.2.8 (Credit Amit Bagaria)

XWLF2, DDLF2 and XXLE4 will require clean Firmware Flash for the CF-root to work.
If You are already using any other CF-root, these CF-roots won't probably work. 
Flash the Firmware again and then flash the CF-root.
