My phone is in an update boot loop I have an update for my Samsung Galaxy Exhibit.
I clicked on Update and it started updating my phone, but now it goes to the update screen, loads about 25% and then restarts my phone. It has been happening for a half hour now, what should I do?  

Taking the battery out did not help, either.
Two options depending on the status of your phone.


If you are rooted and have a custom recovery (and backup), simply reboot into recovery and restore a backup of your original rom.
If you are not rooted, then you will need to download the original firmware file (try SAMMOBILE.COM) and then flash it using Odin - There are lots of tutorials on how to flash using Odin, so I won't go into detail. Once you have successfully done this, then re-download the updated firmware, as it sounds like your original download is corrupted.
