@anil98747 iFixit does not have a guide for the Edge+ but you can check this for the regular Edge [guide|154029] Now, to work on your model, use something like [https://www.youtube.com/watch?v=TLdzV7gw0fA|this video] to replace your screen. As for getting a kit, I assume you are talking about the screen itself etc. you can get those at places [https://www.ebay.com/itm/403703843864?chn=ps&mkevt=1&mkcid=28&srsltid=AfmBOoq_mU3Qs0v8vBMFPo46DP3dLQutry3ER8ZSz-62wIy0pIT8NzPhRsU|like this] and many others.
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.
