Help! AT&T Tilt will not fully boot!! Shuts off!!!

[jmelgdog]

Hi, I have had numerous problems with my AT&T Tilt that I have always been able to have fixed here. This time I must say it is the strangest. Whenever I turn my phone on it goes through the normal boot up. The ATT page comes up and then the 3G bars up come on. Next, the green windows 6.1 screen comes on. Then the phone flashes my personal information with the top portion saying that there is no service to be found. The battery meter reads full before the phone automatically shuts off. When I try to turn the phone back on after that it turns on in the boot loader mode with the multi color screen.

The screen reads:

KAIS1*0
SPL-3.56.0000
CPLD-8

with serial at the bottom of the screen, or USB if plugged into my computer.

When I turned my phone on without the sim card in it, the phone fully booted up and stayed on!

Have been unable to get it to boot up now with the sim card in since it turns on with the multi color boot loader screen about half of the time. Will post what happens when I get the phone to turn on!

What if you use another sim?

For troubleshooting purposes, I woudl reccomend trying to boot it up with a diffrent SIM in there... Sims CAN "go"... I had one go on me once and my phone would jsut lock up during booting (on my old Motorola MPX200 WM2003se)... Went to my carrier, and seeing as my sim was a few years old they upgraded me to a newer sim for free... Hope that is all your problem is

I am having the same problem, but I think I caused it. I had an older mobile pohone with a Cingular SIM card still in it. I swapped the SIM cards because I wanted to use the old phone, but did not want to lose the old card (I really don't know why...). Anyhow, now my Tilt will not recognize the new card when I stick it back in?!
I did search Google, and found this: http://forums.wireless.att.com/cng/board/message?board.id=cingular&message.id=106311

if it will recognize one SIM but not the other then it is most likely the Sim that is bad. try cleaning the gold contacts on the sim with a pencil eraser to take off any stains or dirt stuck to it.
