Issues with notifications, home button - PAC ROM, SGH-T999 topic

Hey y'all! First of all, thanks for the forum, I am using a T-Mobile SGH-T999.

Second of all, I'm having some issues with my recent install of PAC Man ROM (pac_d2lte-release-20141231.zip with gapps4.4.4). The first issue I'm experiencing has to do with the notification drop-down. After I restore from Titanium Backup, I cannot see the tiles or notifications under the notification drop-down. I've browsed through the PAC Settings pretty extensively and have not found a solution to my issue. I did find the tile ribbon that I can activate but it is still inadequate, especially when it comes to notifications.

I do not know if this is a related issue to the one above but, after restoring from Titanium, I do not get a lock screen unless it is on the first boot; after that point, I can make the screen go black with the power button but, when pressed to wake up, the lock screen doesn't come back. Prior to restoring the backup from Titanium, I have no problem getting to the lock screen.

The final issue I am dealing with has to do with the 'home' button on the device. I first thought perhaps it was a hardware issue but, after turning on PIE controls and the navigation buttons, it seems that pressing 'home' does nothing at all.

Thank you so much for reading this post, please let me know if I can be of any further information.

[Q] SGH-T999 verification errors after PAC flash topic

So I have a T Mobile S3 and yesterday I tried to get it running a little quicker. It didn't quite go as planned =/

I used cf autoroot to root the phone, worked fine. had CWM all set. I installed dandroid first, but WiFi didn't want to play nice so I figured I'd just go with my second choice and went with PAC 4.4.4.RC-1. I think I was happier without WiFi - all of a sudden I couldn't install ANYTHING because I kept getting the (apparently insanely common) E: signature verification error. I can't get any google apps to install, can't even flash back to stock. I even had issues getting Odin to recognize the phone at all for a bit, but I've gotten that sorted at least.

Anyway, the phone 'works' more or less, I just appear to only have access to the factory recovery - no matter what I do, I can't seem to get around the signature verification error. I've tried what feels like twelve different ways to install CWM, but no luck. What am I missing? Why can't I even get back to stock?

I've read hundreds of pages in dozens of threads but nothing I've tried has worked. I usually do so well with technology - I'm kind of the dork chick in my circle of friends - and this is really getting frustrating. PLEASE, ask me anything you think might help point me in the right direction.
