@goran and vtec303
Thanks for the immediate response guys. Really appreciate in. I have a few more doubts. Even after doing full wipe every time, I still feels that nothing has been wiped and um on the same boat again. The following is A full wipe right.
1. Wipe data/factory reset.
2. Wipe cache partition.
3. Wipe dalvik cache.
Now after doing this and odin as vtec303 has instructed , I should go to recovery mode, flash 2.0 reboot and then 2.2 right.
