Optimus G Pro Tear Down Guide:

Before you begin you must make sure to power off your device completely.

To start you will need to remove the back cover of the device as well as the battery, sim card, and Micro-SD card.
Next step you will need to remove the 14 Small Phillips Screws (#00) securing the back housing to the device.
Once those screws have been removed you can take your safe open pry tool to release the clips holding the back housing to the mid-frame. (work your way around the housing being careful not to break any of the clips)
Once the back housing has been removed you can now begin to release the 4 pop connectors and antenna cable as shown in the figure below.
You will also need to release the rear camera from the housing using your plastic pry tool (Be careful not to rip or tear the attached flex cable.)

See figure below for screw and flex cable locations.


After all the appropriate connections have been released you can now carefully remove the motherboard from the device.
Be cautious as the motherboard is slightly fastened in the housing with a small clip that could potentially damaged the small and narrow portion of the motherboard.

See below figure for reference


Now that you have safely removed the motherboard you can now begin removing the last few necessary components to start the screen removal process.

First you will need to lift up the touch screen digitizer's flex cable and remove the ear speaker (both are held with a little adhesive)
Next you can take your plastic pry tool to gently pry up the lower USB port / soft key assembly and remove it from the device.
You will now be able to begin applying heat to the screen assembly to be able to remove the LCD and touch screen digitizer.
Using your heat source on a medium setting you will want to evenly apply heat to all outer edges of the screen for 30-45 second intervals.
Be cautious not to hover over and flex ribbons that you may need to reuse for re-assembly.

Another Tutorial on how to replace the Digitizer / Screen

Thanks for the wisdom. I ordered a new screen for my 980 and expect to try to replace it Thursday or Friday. I used to repair iPhone cracked screens, so I'm hoping this won't be too bad. I'm thinking about making a tutorial along the way and if it works I'll post it, since the one by Repairs Universe doesn't have the actual glass replacement included, otherwise it's a great tutorial. Thank's again for the help.

Well, I got the Digitizer today and spent 3 hours replacing my broken screen. I also made this step by step picture tutorial that hopefully will supplement the www.repairsuniverse.com video. I hope it helps. All the best !!!

My experience

Good tutorial. I used this and another teardown guide to replace the digitizer on my E980. I'm not really a hardware guy, and I have limited experience taking stuff apart like this, but I was successful in fixing my phone using a small philips screwdriver, a plastic pry tool, and a blow dryer.

When removing the motherboard, notice the clip that is highlighted in the photo. To move the mobo around this, I started at the bottom of the phone and gently lifted up the bottom of the mobo. Once the bottom is pried up, work the middle, thin part of the motherboard around the clip. If the motherboard won't lift out, check again to make sure you lifted all the highlighted clips and removed the phone camera.

The ear speaker is the black rectangle located at the top-center of the device. Notice how the ear speaker has a little extension that goes off to the right, and which wraps around a screw-hole. Try prying it up from this extension. Perhaps try a shot of heat from the blow dryer to loosen the adhesive, if it’s stuck fast. (I gather you can damage the phone with too much heat, so be careful.)

The digitizer flex cable is the top-right-most flex cable. Trace the flex cable to its base – this is the part that is held down with adhesive. Pry the orange base up from the gold foil backing below. This assembly is attached to the digitizer, and it threads through the body of the phone so that you can remove the digitizer.

A cautionary tale: I wrecked the original adhesive pretty bad when I removed the digitizer from the phone body. I tried re-using the original adhesive by smooshing it back into place, and by wadding up little balls of the used adhesive and placing it in strategic locations. This turned out to be a bad idea – when I put the digitizer back on the phone, it didn’t sit exactly flush with the phone body. I said “oh well” and put the phone back together anyway. This was a mistake; the phone worked fine, but dirt started to collect under the digitizer after keeping the phone in my pocket for a couple of days.

I recommend that you get replacement adhesive. It’s only a few bucks for a huge roll of it on Amazon. I used 2mm width white/clear adhesive, and it works well. I got replacement adhesive, took my phone apart again, and replaced all the original adhesive with fresh stuff. After this, the phone is good as new!

When I took the phone apart, all 3 physical buttons from the sides (volume, lock, and quicklaunch button) fell out, which is expected. When you put the phone back together, note that even though the lock and quicklaunch buttons are the same size and shape, they are not interchangeable. Examine the buttons and their receptacles and you will see which button goes where.

In LgOGP the screen glass and LCD display are separated and you can change only one of them without affecting other.
Latest models are with One glass solution displays. In this case you need a stand, uv lamp etc. to replace only screen glass.
