  3. Nope, still the same.

  4. The download link is wrong (jeboo_kernel_i9100 instead of CM10 4.3)

  26. this file has extension of .tar hence it is not showing in recovery mode in sd card. what should i do?

  27. I downloaded jellybean 4.3OS but it is in .tar extension when i am downloading it and transfering to SD card than in recovery mode the tar file is not showing in it so plz let me know how i can updtae my ph.
