Yes, same thing happed to my Mogul. Sucks huh. Anyway I was told by another forum member to load the old 6.0rom on using a USB cable. Then reload the 6.1 using an SD card. This should fix it. This is becoming very common now. I did not get to try it though.......
By the time I got the reply I had already forked up $55 to Sprint ... Those #@$$%!!
If it works please let me know! GOOD LUCK!
