N900 not booting

Yesterday I messed with easy debian chroot on my N900 so, I deleted the easy debian image and copied fresh one to my N900. When I was trying to install phpmyadmin in easydebian, suddenly N900 turned off and then rebooted. It was stuck at showing five dots animation splash screen foreaver and never loads desktop. I tried to reboot, remove battery and inserted again. Still my N900 not booting. As a last resort, I tried to flash N900. Flashing went well but still the problem was there. I thought I bricked my N900. My wife will kill me if I ask another N900. :(
