I have the Samsung Galaxy 10.1 Tab 2. The Touchwiz message pops up now and again. I´ve just done a reboot using The Guide to Rebooting instructions. To get there pressing the Volume Up and Power buttons brought me to an ODIN downloading process. I restarted the Tablet, and used the Power Button and Volume Down route to get to the recovery and reboot process. I wiped the cache and did the system reboot. I still get the Touchwiz home message. Would definitely appreciate any help I can get to remove this message.
