Hi Napa21, Thank you for posting. I know that the Verizon diagnostic utility found out some issues. I am sorry for my limited recourses of this software. Regarding this, since the software is designed by Verizon and they may be the best source of your question. Therefore, please contact Verizon for help and keep me updated.
