Then i got Samusng Galaxy S2 GT-I9100G and stared custom roming and rooting stuff.. After losts of soft bricks and hardbricks i managed to install rootbox rom with codeworkxx custom kernel in it..
But when i booted the the phone then the phone didnt detect sim card i tried restoring to original OS it sill didnt work..
Then i came across efs problems in xdaforums.. So i tried to use efs pro v1.7.14, backed up my efs and tries to restore them.. It didnt work then i downloaded a efs.img online for my phone and tried to restore my efs with that.. I didnt work also..
I tried to restore my backup and efs pro showed me this error...
