I'm having issues when it comes to the ##DATA# manual programming. I completely flashed my SPH-L710 (Sprint) to MetroPCS with Talk, Text, Data & for the most part MMS working just fine. EVERY SINGLE TIME I do the ##DATA#, within less than 20 seconds my signal drops to nothing, then resets the signal. After I set up everything in the ##DATA# part I reset the phone its gone by the time my phones powered back on when I check the data profile by doing the ##DATA# part and just VIEW, not EDIT everything is gone from when I programmed my Data Profile, EVDO, Advanced, Others etc.
I'm attaching pics in order so you know what Im talking about. The first person to give me a solution I will "donate" $50 to them..
