Step 3: Now click on “PDA” and browse the directory where you saved CWM recovery file. Still on ODIN interface, be sure to check options Auto Reboot and F. Reset Time and click on “Start” button to begin the process.

Step 4: Wait until your device is rebooted; that means that the CWM installation is complete. Just after you see the home screen, you can disconnect your tablet from your computer. But that’s just for the installation of ClockworkMod Recovery.
