Q. Have you got in cwm recovery loop i.e. when you reboot your phone it goes in recovery mode?
ANS. No probs. Just remove your battery and open download mode manually by pressing Power button+Home+volume down key. If you do like this only then download mode will support your odin otherwise it won’t supprt. After this just flash your cwm recovery again.
