Screen freeze on start up WM logo

[thamania]

When booting the screen freezes but it is still booting on the background and active sync connects on my pc.
When i try to change ROM it gives a communication error, on active sync i can still explore all files.
What else can i try to fix this ?

Can anyone please tell me how i can put complete new software in this device ?
Active Sync connects but upgrade util gives comm error and stops ROM update.
