      Odin Software given here is working properly. Make sure that your laptop does’nt contain any kind virus(.exe). I think this is the only cause that Odin does’nt start on your laptop.

    After “Step Four”, my device does not restart and it hang up at the Samsung Galaxy S II GT-I9100 Logo whit the yellow triangle. What’s not right?

    • Search and download this kernel file “CF-Root-SGS2_XX_OXA_LP1-v5.2-CWM5.tar”. So, in that way you can install new custom rom and your phone will definitely reboot normally.

  17. India says:
