Tried it but still have partial root. Cannot change system /app to R/W. Please help!This is the so-called "partial root".
To solve this first flash a CF Root Kernel here using PC-Odin under the "PDA" to get proper root & cwm recovery. You have to extract the .tar file out from the .zip file, PC-Odin read the .tar format.
Then you install and run TriangleAway v1.5.1 to remove the yellow triangle & reset flash count caused by the PC-Odin.
