Good Question
And NO tar file in Speedmod rar file. (but I believe its the 6 meg file which needs .tar addad) OR ?
Flash with pit 512 + repartition + Phone efs clear + Phone bootloader update!
For the Kernel you need to Odin version of the speedmod K13D, you can find it into the SpeedMod topic.....it's a .tar file, just flash it as it is!
