Hello Everyone, I have replaced the screen as @aadamomar and @dadibrokeit had recommended and the phone is now fully functional again. I still have no clue as to what happened to the old screen but the phone now works! Thanks so much to everyone for your help!
Hello Everyone, I have managed to fix the issue. I had to purchase a data cable to connect to an older windows xp pc. I then installed SETool2Lite and it’s appropriate drivers. I then found the rom files for the phone and restored its software, after which the phone booted just fine. Hope this helps anyone with the same problem as me!
