I jailbroke my phone last week and it's been fine thus far. Today I replaced the default font via SSH, and then restarted my iPhone. It now won't turn on! The Apple logo is all I see, and then the spinning/loading icon appears for a few seconds then it stops spinning. The only way I could turn it back off was to hold down the Home and Lock button. I replaced the LockClock.ttf font with another one. However, the font file wasn't .ttf it was .otf. Could this be the reason?
