I was trying to flash with SD card, and it would error (phone restarts after starting to update somewhere 0%-8%).
I thought I updated the post earlier, but I must not have hit the Post button....
Anyway, I had finally gotten the radio to successfully update to 3.42.50 after multiple rom/radio/bootloader changes using both SD flash and RUU.
This did not change anything. Still no service.
I am sure, at this point, that it is something I did with either EPST or QPST/CDMA workshop or DFS.
If anyone has a backup of settings for their Titan for one of these programs and would be willing to share, I would be EVER so grateful. I am on Verizon, so I believe I would need a copy of a VZW device, however, at this point, I would try any service provider. Any service registering is better than where I am currently.
