Root Used milestone overclock and now phone wont boot

Hey guys,
I was using milestone overclock to switch back to my default 550mhz when my milestone switched off and on restarting, wouldnt get past the m logo. Now it wont even start up.. did I brick it?

Got the same problem - after struggling a bit I got it going again, but now the same problem exists, I'm even unable to switch my phone on.

Edit:
Correction, when I try to switch it on - nothing displays, but it makes the startup sound.
