Resignation revoke

Tomorrow 3rd dec is my last working day, but my project kept my allocation for one more day till 4th decso that if i revoke then they will keep me in same project. What if I dont do exit formalities like id card submission and laptop return, and on 5 dec I'll report back to office and ask HR that i was I'll and now I've changedy mind and want to revoke my resignation, will they accept this?? Will they send to me rmg??? If yes then from rmg, can I be transferred to Noida rmg as my home is there??
