My phone's display is not working

@aradhnabhardwaj well you are not giving us much information. To get started I would suggest that you replace the LCD screen with the midframe. iFixit does not yet have a guide for that. Use something like this video to change your LCD. REplacement displays are readily available at may online stores. Use a vendor within your geographical area so you can assure that you purchase the display for your particular version of the A01

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
