How do I replace a cracked screen?

Just remove the screen frame from the backing using a hair dryer and guitar pick. There is a small seam around the screen that separates the halves. Once you work your way around the halves will come apart but careful there is a ribbon cable still attached inside. Don't break it. Using tweezers pull up on the connectors on the ribbon cables for the LCD and the digitizer to disconnect them from motherboard. Then slide a flat tool under the battery and gently free it from its glue on the back of the LCD. Keep its cable attached to the motherboard. Then unscrew the motherboard from the frame and remove the adhesive holding on the antennae cable onto the back of the LCD. Basically just free anything stuck to the LCD. Now flip the motherboard and battery onto the backing and set aside. Using a guitar pick carefully go around the edge of the LCD screen to free it from the clips in the frame. It will come out - be gentle or bending it will break it. Lastly using guitar pick and hair dryer on the front sides go around under the glass digitizer and free it's glue from the frame. Buy some cell phone adhesive 1-2mm to glue new digitized on then reverse everything and connect it all and fit it back together. Make sure it's s clean environment with no dust or hair.

The screen is very easy to replace,If you order a new digitizer from china it will come with the tools as well,At first you unscrew the tablet it will be a total of 7 screws,Unplug the the broken digitizer,then take a guitar pick from the top and work it into the broken screen it will be kind of hard at first,work the old screen out.clean the outside of the old screen old glue from the tablet.After that everything els will explain itself,remember do not break the retaining clip from where the the new cable will plug in to the tablet it just lifts right up it doesn't pop off but lifts straight up!
