  1. Can anyone help me? The first time I did this about a month ago it worked fine and I had a few TIM apps which could be deleted. However I recently had to change the firmware to ICS when I tried putting JB back on it worked but it was branded on TIM and had a TIM bootscreen and non samsung Icons on the home screen and app drawer. Can someone help me because the first time I put this firmware on it only had TIM apps and didn't have TIM bootscreen or icons.
    Any help will be really appreciated Thankyou in advance :) (HELP ME PLEASE)

  2. Find apps at Play store that can freeze or change the default bootscreen.

  3. Have you put this firmware on your phone?

  4. Oh haha well thanks for the help anyway
