ATT SMT5600 - Stuck on mMode Boot

[Guest kwan888]

Hello all,

First time poster.

I just recently got a SMT5600 for ATT. I love the phone, but I've recently run into some issues. I turned off my phone after I had exited the IE browser, but I saw that it was still connected via GPRS. So I decided to turn off my phone to kill the connection. That was a BIG mistake. After I turned it back on, after the Audiovox and Windows Mobile startup splash screens, I will see the mMode splash screen. The phone will then proceed to make several consecutive beeps that go down in volume.

Then I will see a "Configuring Device" screen with a progress bar underneath. Once that goes to 100%, I will get another splash screen. This one says at the top "Cold Boot Config." Then under it says "alert" and "Please press OK to restart."

I will hit OK to restart, but then the phone will go through the exact same process. Needless to say I have been pulling my hair out trying to fix this.

Here is a list of things I have tried:

I cannot exit the last "Cold Boot Config" screen. I can recieve calls, but cannot make them. I have tried a hard reset, but it solves nothing. I can connect to the phone via USB Activesync.

I figure that mMode is trying to update something, but because I killed the connection prematurely, the file never finished. And it's stuck in a loop trying to update with a corrupted file.

My guess is that I would have to flash with a ATT Rom to fix this issue. Am I correct in assuming this? Any advice or suggestions is appreciated. Thanks much.

Welcome to the site :o

It sounds almost like your phone is partway through a rom update.

Before playing with update I would try a Hard Reset first as that shou8ld reset the system for you.

If that does not work then reflashing would be the next option.
