These are the same commands that I have previously entered via terminal emulator and I tried again via ADB method. I have tried multiple times.
I'm not sure what you mean by "You must have to copy moded su to your sd card , /mnt/sdcard". Are you referring to the su file in my xbin folder? If so, I cannot copy it because I am not rooted. Every time I execute the aforementioned commands, the su file in my xbin folder gets modified. The size of the su file in my xbin folder is 0.00K, is this normal?
Thanks for responding, please offer further guidance if you can.
