Not sure if this is going to help out.
But in the passed I bricked 2 or 3 optimus v's tinkering around on them.
Where it would not get pass the boot animation.
All I did to fix my problem was call up virgin mobile (in your case straight talk) I told them exactly what was happening. (Keep in mind they did not know my phone was rooted) they would run me through standard company procedures to try and help me fix the phone. Non of them worked obviously, next they simply said they would send me out another phone since mine seem to be "defective". They would send me out a new one and I would send back my bricked optimus.
That was my solution when this happened to me.
Note I did do this a few times and they never caught on.
So maybe if straight talk is as nice as VM, you should be fine. Only downside is just having to wait for your new phone to come in.
Yet again hope this helps you out
Oh, and when they asked when this started happening all I said was when I went to turn on my phone it just started doing it.
