    • Remove the metal tape to reveal the ribbon cables connected to the screen

    • If you wish to preserve the LCD screen for whatever reason, it is recommended you use a heat gun around the sides in order to weaken the adhesive that keeps the screen in place

    • Take something thin, such as a knife, and wedge it between the screen and the body of the phone

    • One you have created some space, wedge your plastic opening tool into the space and remove the knife

    • Move your plastic opening tool up and down the side of the phone while lightly pulling up. Repeat this for all sides until the screen comes out

    • If you wish to preserve the LCD screen, be careful how deep you wedge the plastic opening tool in and how hard you pull up to get the screen out. Depending on the depth of the plastic opening tool and strength used, there is a high risk of damaging the LCD screen

    • Remove the old adhesive from the body and replace with new adhesive so the new screen will stay in place

I have a working LG G3 screen (44 pin connector) that I'm trying to jumper wire to a LG Zone 4/Aristo 2/Phoenix 4 (Same phone 210) with no screen (40 pin connector). I have the connector pin outs for both but I want to know is this possible to do?? Scenario: I'm on a deserted island and can't buy a replacement screen for my Zone 4. I know it's going to be a long and tedious task but are the voltages even compatible enough to attempt this?

Please contact me at s.e.davis8304@gmail.com or amebrizee@gmail.com if you know anyone who can help me with this information. Thank you.
