[Q]Phone launches to black screen without launcher, and firmware flashing didn't help

[slixzen]

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.

Try clearing your launcher data from settings (I think it's TouchWiz Launcher unless you're using a custom launcher). If that doesn't work, then you might have to use Odin to flash a factory image.

You can probably refer to this guide. It might help!

And if you want to completely reset your phone, you can download the stock firmware here.

Then use the .tar file in Odin and go from there. You should get a fully stock Galaxy S4 (with stock recovery too)
