How do I disassemble Samsung Galaxy Amp 2 to fix digitizer/lcd display

Hello, I recently had my galaxy amp 2 break, (Digitizer shattered) and I figured out how to repair. Since there are no screws on the back of the phone that means they are under the screen.

First at the back of the phone, there is a little hatch or cover covering the screen ribbon cable located at the top right of the back, use a spudger or razor to pop it out and undo the ribbon cable. Then using a hairdryer or heat gun to melt the glue sealing the screen to the phone, use a metal spudger or razor blades (exacto knife will do), pry the screen from the edges of the phone and reheat if necessary. After the screen is peeled off, the silver shiny part (digitizer) is also adhered to the motherboard, using a heatgun or hairdryer will do the trick to get it up, be very careful as the digitizer tends to be extremely fragile and can get glass shards everywhere. After the digitizer is removed you can then use double sided tape or adhesive of your choice to install a new screen. If you have any questions feel free to email me at jakubd309@gmail.com Thanks!
