2. Passo 2
  Lift the back cover to release the rest of the plastic clips and remove it.
  
  In case you can't lift the back cover completely, slide your fingernail or your prying tool around the midframe to release the remaining clips.
  
  To reinstall the back cover, press it firmly into place until you hear a snap from the plastic clips to form a seamless connection with the rear side of the phone.

  Insert an opening pick between the bottom right corner of the motherboard cover and the motherboard.
  
  Pry up the motherboard cover to open the plastic clips which hold the cover in its place.
  
  The clips can be a bit resistive. If you're having trouble prying up the motherboard cover, slightly rotate the opening pick sideways to make the process easier.

1. Passo 18 LCD and Digitizer
  Remove the metal tape to reveal the ribbon cables connected to the screen
  
  The metal tape is stuck on there pretty well. Get the plastic opening tool under the right-hand side and corners and slowly work your way to getting it off
  
  Be careful when removing the metal tape. We can reuse it after we replace the screen

2. Passo 19
  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

  Before reassembly, be sure to transfer the front speaker grille if it is not included with the new screen. If not, carefully push the grille out from the old screen, then reinsert it on the new LCD.

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.
