Factory reset hangs my phone

Hello all.

I am using a Vega Sky Pantech A830.

I am new to android so I was very excited to do some techie. However I got to a point where I don't know how can I rollback, so I decided to do a factory reset.

The problem is, my phone now cannot do a factory reset. After it reboots, it stops at welcome screen forever. I believe my phone has been hanging for 1 hour when I come for help.

Is there any one know what problem I may facing with this, and how can I solve this?

Thank you in advance

I root my phone, and install a theme from Apex Launcher. I got no problem with it since I can do factory reset with the theme.

Anyway, I cannot find a button to answer B. Diddy. Can you show me?

Welcome to Android Central! It would help to know more about what techie stuff you were doing. Did you root the phone? Install a custom ROM? Delete any system apps?
