razmig, how long have you waited? In the odd case it has taken the BlackBerry 20+ minutes to boot up for some. Give it 30 minutes after removing the battery to be sure it isn't going to boot. And remove the battery while the power is on, and remove microSD media card if you are using one.
Do that and let's see where you stand.
