You can use the Overcome method. The link is in my signature.
- because you are on Froyo, you need to check if you have a locked bootloader (GB has no such issue).
- you need to first root your tab, (I used z4root), then install the bootloader checker to check if you are affected.
If you do have locked bootloader, then patch it.
(All of these are also in the Overcome PDF guide)
- Once you know you do not have a locked bootloader, download GB-stock-safe-v5, and Overcome Kernel v4 tar file.
The GB-stock-safe-v5 have Odin and windows driver and everything you need.
Use it according to the guide, to flash a baseline GB stock rom.
The continue with the guide to flash overcome kernel 4.0
At that point, you have CWM as it is part of the overcome kernel. (You don't have to continue with the guide on flashing overcome ROM. It is not needed at all).
So go ahead. Don't rush. Root and check bootloader, then read the guide many times.
