I have seen a lot of people have this problem but mostly on sprint phones and not the Verizon phone. I have tried reinstalling the Radio and Keeps on failing. I have also tried to reinstall the RUU vzwT6.3.09.605.2_0P3PIMG.zip but that fails also. I reinstalled the recovery multiple times cm and twrp. I have also reinstalled the firmware ViperMax 2.0 this is what I was running before I thought I wanted to play with something new. How ever I still get the com.htchtcdialer error at each boot. I have cleared the cache multiple times and formatted the partition. any help would be a great help.
