My Evo won't update

[Memfus_boi]

I tried to update my evo, but i have this problem...... a pop up ask me do i want to update to 1.32.651.6 on wifi or network/wifi. So i click wifi only because i get bad reception at home. At 1st it says the update is corrupted and i download it again. so it downloads........ when i install it the phone restarts and begins with the installation. A sync symbol appears over a pic of the phone. then a question mark shows up on top of the pic of the phone. after a minute, it boots up the phone like normal, whats wrong with this update??
