I have this weird problem. My Sprint Touch is running on the 2.13 radio and I had wanted to upgrade to the 3.37 Sprint radio. So following the steps for the upgrade, I first used the Cokeman's Vogue unlocker MFG 2.31 to unlock it. I am getting the SPL 2.31 Coke displayed when I boot up after holding down the power and camera button so I guess I have unlocked the phone correctly.
The problem is, I haven't upgraded the radio to 3.37 as I thought I would do it a little later, but what is happening now is that the phone works perfectly fine when it is in active mode, and is able to make and receive calls, but the moment the phone goes off into standby mode when I leave it idle, then I am unable to get it back to active status unless I do a soft reset. When it is in that condition, incoming calls aren't picked up by the phone either though at the other end of the line the caller is able to make a connection and doesn't show my phone as being off line.
I have tried re flashing back to the OEM 2.13 Sprint ROM but the problem persists.
Could some one help me fix this please?
Thank you.
