I had flashed a custom rom on my diamond but the settings on the EPST weren't sticking. I had to flash back to a sprint stock rom but preventing it from doing the customization part so that i will keep all my metro settings. After that I followed the tutorial to change the required EPST settings and it worked. after that i flashed to a custom rom, made sure the settings were still there then went ahead and set up my connection. my data works but mms is not downloading the message but i do get the notification.
