TWRP (team win recovery project) is a custom recovery for the Samsung Galaxy Tab 7.7. It provides same functionality as the original custom recovery we posted for the Tab 7.7 few months back but uses more user friendly UI. It is also fully driven by touchscreen input which makes more sense on a tablet.
To download TWRP, you can either go to this link or install goomanager from play store. Of course, to run it, you must root your Galaxy Tab 7.7 as it requires super user permissions. Open Goomanager and provide it root permissions.
Then, select “Install recovery” from the menu.
