Itr processing

hi,

I had filed ITR in July 2017. It wasn't processed till last week and i had also recognized some mistake in the ITR. So in order to rectify the same i had filed a revised return in 1st week of October. Today i have recieved refund for the original ITR - so in this scenario will the Revised ITR be processed again? And, if the tax refund is less in the revised ITR then will IT department will make a tax demand? Further, can i again revise the ITR back to original one immediately?
