Basically what happened is I was in the middle of deleting and upgrading some packages via Cydia, after upgrading i was prompted to reboot my phone, which i did. Now it's stuck on the Apple logo and it won't turn on. I've tried holding down the home and power buttons, but again it's still stuck. Did this about 4 times with the same result. If anyone can help me out I'd really appreciate it! Thank you!
