Steps to remove the digitizer.
The backplate is held down with internal clips, place a spudger inbetween the backplate and the midframe and py the backplate away from the device.
Once the clips are free, the backplate should be easily removed.
The digitizer only has 1 connector, lift this connector up.
Insert a spudger inbetween the digitizer and the midframe. the adhesive they use is very strong, so once you have some pulled up and can pry (pushing against the digitizer so not to scratch the glass) and it will pull up most if not all the glass without leaving any behind.
DO NOT use heat on these devices, the lcd is poorly made and the midframe is plastic, a heat gun will damage them.
DO NOT use acetone as a cleaner on this device, it will ruin the LCD.
