Looks like you have the same Problem as i have. Check if your GSM-Module is still doing: You have to get into the Bootloader and check if it says "GSM OK" (then you are a lucky owner) or if it says "GSM Error" (then you´ve got the same problem as I´ve got). If it is the second case: Try this one: http://forum.xda-developers.com/viewtopic.php?t=1182&highlight=solved+gsm+error

Or this one: http://forum.xda-developers.com/viewtopic.php?t=4123&highlight=screen+1

But i need to say that these tips haven´t helped me out of this Prob. I hope it will help you!

So long...
