Posted under normal Marquee forum also. Just figured maybe all you programmers may be more knowledgeable I installed CT Mod two days ago. I was changing the DUN NAI setting in the hidden menu to allow tethering like I've read about and done before. I accidentally hit the PPP Carrier menu below it, panicked, and I'm not sure what I hit. My phone rebooted and completely lost signal, no voice or data. I manually tried to change the MIN and MSD settings, and the MMS url to boost, and then the Data Profile Username back to my own (it turned to email@example.com?). I now have Roaming Indicator On. I flashed back to the stock ZV4 rooted ROM, and can make calls and texts, but still have the Roaming Indicator On and the triangle above the signal strength bars. I can't update PRL (even though it's still the Boost PRL 61007) or update the Profile. What do I do? [EDIT] After using the reprogramming code, I still have no voice service. Three different Boost and Sprint engineers have told me that it may have to do with sprint updating their network and towers, and may be on full capacity. While I'm not sure this is true, time will tell. As far as what causes service to run out, its happened to me only when I'm in a ZVC ROM; with ZV4 stock rooted, I don't have the Roaming Indicator problem come up anymore. If you have issues, use ##786# to reprogram and wipe everything on your phone. Use ##72786# to reprogram ONLY, without losing Apps/contacts/all personal data not on the SD card. This is the code I would use. They only worked with stock ROMs for me.
