    Always make sure your device is fully powered off before you begin the dis-assembly.

    • Take your Torx T5 Screwdriver and remove the two (2) screws located at the bottom of the phone.

    See figure below for reference:

    • With the back cover removed lift up the protective film covering the battery's connection. Then take your Small Phillips Screwdriver and remove the 2 screws securing the connection.
    • Next remove the eleven (11) Small Phillips Screws circled in the figure below.
    • With these screws removed take your safe open pry tool and pry up the back housing and mid-frame releasing the clips holding them together.
    • Now that the back housing is removed and the motherboard exposed you can start releasing all of the necessary connections.
    • In the figure below you will see ten (10) connections that will need to be released. You will also notice on the right side the volume button flex will need to be lifted out of the slot in the housing.
    • With all the connections released you may now gently lift out the motherboard from the housing.

    See figure below for reference:

    Take your pry tool and gently remove the rear camera from the housing. The camera is held down with a little adhesive.
    Next you will want to pry up the headphone jack flex assembly from the housing.
    You will also want to remove the gray rubber grommet shown in the figure below.
    Next take your safe open pry tool and lift up the charging port flex assembly which is adhered to the housing at the bottom.
    You will find that feeding the 2 antenna cables through the clips on the housing to makes room to lift out the charging port assembly and be out of your way.

    See figure below for reference:

    Now you will need to use a heat gun or blow dryer to apply heat to the front of the screen assembly
    This will help loosen the adhesive holding the screen in the inner bezel.

    On a medium heat setting apply heat in 30-45 second intervals hovering about 3-4 inches away from the screen and housing. During the removal process you may need to re-apply heat to stubborn areas.
    Once you have loosened up the adhesive enough take your safe open pry tool insert it between the space of the housing and the screen assembly.
    Slide your pry tool along the sides of the frame to release the adhesive holding it in place.
    Finally, you will need to slide the flex cable through the slot in the housing to completely remove the screen assembly.

    See figure below for reference:

    Before you re-assemble your device you will need to clean up the old adhesive and any glass shards that may have been left behind from the removal process. You will want to cut and apply new adhesive to ensure your new screen replacement is secured properly and fits a flush as possible.

    Great guide, repairsuniverse. I did have a question that I hoped you could answer. I've noticed there are many similar model numbers to the one listed in this guide (E970), such as the LS970 or the E973. The prices I have found on such replacement screens/digitizers have varied widely based on these model numbers but I cannot see much of a difference on the pictures. Are these Digitizer Assemblies interchangeable on these models?

    Thanks for all your help.

    Thanks mdmoose29! To answer your question the LCD + Digitizer Assemblies are very much different. The price difference could be a fluctuation from the manufacturers availability and price.

    Do you know if it is possible to replace JUST the digitizer? I apologize if this was already covered but I'm in a rush and I'm very tired of seeing such high prices for lcd+digitizer glass replacement. I don't think my actual screen is cracked, just my digitizer and I need a new one and quick. So I found a digitizer for the e970 from china for 22 bucks 30 bucks shipping but before I order it I need to know if I can separate the old digitizer from the lcd screen that way I can just replace the digitizer

    Sorry to say but your suspicions were correct. For this device the touch screen digitizer and LCD screen come fused together. It is nearly impossible to successfully separate the two parts. Unfortunately your best bet is to purchase the combination screen (touch screen + LCD screen).

    What type of adhesive is use on the lcd screen.

    We usually use 3mm double sided film to re-attach it to the housing.

    Could I get away with using 1 mm double sided tape

    I would think so.. make sure you place it fully along the edge of the glass. You wouldn't want it lifting up in the future.
