My phone use to be running stock rooted 4.2. I kept receiving messages about the OTA Update. I was going to take the update because I was having problems with my rooted 4.2, however, my phone would not take the OTA update. I think it was trying to tell me something lol. So i downloaded the official 4.3 file from the Samobile website. I used Odin to flash it to my phone. After doing this my phone has been a huge hunk crap. The thing that annoys me the most is that the vibration feature is not working. So read where people were talking about using Odin to reflash the 4.3 file. My only question is will this brick my phone? I haven't found any definitive posts reassuring me that my phone will work again after doing this. I just know that the 4.3 pretty much has everything on lock down and didn't want to brick my phone by trying to re-install it.
