Unhappy [Q] Tried to install fonts but now my phone is not starting

i am new to rooting...So this is what happened
I tried to install fonts using rom toolbox pro...
Didnt liked new fonts so i tried to restore from backup
My phone restarted and stucked on logo..
Then i went to recovery mode and selected wipe memory/reset..
The phone started like new...but after some time i got "Android Upgrading"
and my phone restarts again and again,....

As i am new to rooting i have no back up for rom...What options i have now..

My phone is micromax A110 HAVING Android 4.0.4
PS The manufacturer has added updates to android 4.2.2.So can i use it
