[Q]Phone launches to black screen without launcher, and firmware flashing didn't help
I had been having issues receiving mms messages, and after going through the steps with one of the phone reps to do ## codes. Now, whenever the phone turns on, I am presented with a black screen (where the launcher would be), and then I can't launch any applications. I can still navigate through the settings menu.
I tried downloading the SPR-L720VPUAMF9-20130626162512 file firmware that is posted in the general section, but this didn't seem to actually fix my problem. As I still can't activate the phone on the network, and I can't boot into the launcher.
I would really appreciate it if someone could help me out with this. I think the next one I will try will be the rooted deodex from crawlj. But I do need some help, either to get the entire phone back to stock (or stock w/ root) or just to get it to activate on the sprint network at the moment.
I was able to get the phone booting, but am still unable to get the phone to activate on the network. It shows up as custom under Settings > About Device > Status, and if I boot into Odin mode, it shows as custom for everything, even though I have installed the stock recovery, kernel, modem, etc.
