If you broke your screen ..there is nothing you can do but to replace it.If it is only the glass,it should be working because the digitizer,on samsung devices,is on the screen .If you dont want to replace it ,you can plug it to your pc..take the things you want and leave it.Another tip* you can buy a MHL cable .So you will plug it to your TV and therefore you will have the TV's screen to be your mobile's
did you try another cable? maybe its the cable..next you have to check your port (and for that you have to plug another cable,if it doesnt work ,it means that your port have some kind of problem .). Also check your battery if its okay..Sometimes the battery may expand
If the HDD is the main C: that runs your current Windows and it's inside your laptop ,the only way is to plug a Win setup bootable usb (or a DVD) and complete installation overwriting your previous A second solution is that if it's external HDD , plug it to another pc and format it so as to be clean as you say and therefore plug it again and do your installation
Obviously i assume the digitizer is replaced to your phone.Its not a big deal ,its the 3M double tape that didnt glue well to that spot.Try to put a new one (a spike in size ) but be careful because if you lift the digitizer with a little more pressure you will earn some lovely burned pixels :). (Had the same problem with my LG G2)
I had the same problem with my LG G2 and im afraid to say but its 90% the digitizer .It has to do with the cable that connects it to the screen.The fact that your half screen worked,it is because a part ofthe cable cut or distorted in general .If you are lucky a good repair shop could save the cable. On the other hand your digitizer costs about "6 to 7 euros "on ebay and the fitting shouldnt be more that 20 -30 eur.
