1) How did you try to reinstall apps? Titanium? If so, did you do a batch restore of everything? Did you do settings as well?
2) Can you give a little more information about this screen your stuck at? What does it look like? Does it go to the splash screen first?
3) If you turn the phone off then back on while pressing and holding the volume down button, you should get to hboot. From there, select the recovery option. Do you still have a custom recovery?
Just installing some apps can cause major problems if done wrong, but it shouldn't ever affect recovery, and most definitely not hboot. Assuming everything works with #3 above, we can get things working again. Let me know.
