Hi jsanseverino, and welcome to AF

Sorry to hear you are having problems. Can you tell us which sort of S4 you have (country and network will probably be enough)? You'll get your best help in the device forum, but because there are differences between say a Verizon S4 and and international GSM model we have separate All Things Root forums for those. If you can tell us which model you have we can get the thread moved in order to get you the best advice.

I think you are probably right that you restored something incompatible from Titanium. What I don't understand is why you can't get into recovery. However, I don't know Samsungs, which is why I think it's best we seek help from other owners.

 

When you restored from titanium, did you also restore system apps? That can cause problems. You only wana restore user apps :thumbup:

 

Power phone off. Press and hold volume up, home and the power button at the same time.

Please tell us which carrier your phone is on as well as there would be more help for you if we can move your thread.

I don't use titanium, I use MyBackupPro.

 

You could be in trouble then man. How about home, power and vol down, does that do anything?
Please tell the mods your country and carrier mate. There are people who can help you better than us :thumbup:

P.s, youre doing the button thing with the phone turned off, right?

 

Try using android commander on your pc, once you dl Ac on your pc plug in your phone and ac give you an option to boot your device in recovery.

 

I think USB Debugging would have to be turned on for that though?

 

you hold volume+, home button, power button. once the phone begins to start let go of the power button.

 

I think you flashed the wrong ROM.
