Introdução
This guide will show you how to replace the screen touch digitizer display with frame for LG K30.
Make sure that when prying the front-facing camera off of the frame, use caution so as not to cause any damage to the connecting points or to the frame.
O que você precisa
-
-
Power off your Phone before beginning disassembly.
-
Use the 'Jimmy' and 'Metal Spudger' to slowly pry open the outsides of the back case.
-
-
-
Remove the thirteen 3.4 mm Phillips #00 screws securing the midframe to the display assembly.

Use a spudger to pry the battery from the phone.
Are you sure a metal spudger isn't better suited for this task? I am currently doing this guide and my plastic ones barely did anything to the adhesive, while also occasionally bending and landing a few scratches on the battery's covering. Metal spudger eventually took care of it, but I am also worried about accidentally hitting a few things on the motherboard and that thw adhesive tore a small part of the battery's covering (which I put back since it was sticky, but now I am worried that I might have to replace the battery.
Apply a few drops of 91% alcohol along the two sides and the bottom edges of the battery, then place on a hot plate at 80*c for about five minutes. DON'T use a metal Uspudger;I use a plastic iFlex and go under the edges ofd the battery. You are right, the adhesive is extremely strong and unnecessary, but you have to remove it WITHOUT bending the battery if you plan on reusing it.

Re-assemble with replacement screen/frame.
This instruction guide is only about 3/4 complete. There are several small items that must be transferred to your new display with frame that are shown still attached to the frame in the above photos. These items are:
- Rubber piece for Upper Microphone (grey, upper left of frame)
- Rubber piece for Lower Microphone (grey, lower middle just to the left of the charging port)
- Rubber piece for seating the Proximity Sensor (black, upper middle just to the right of the earpiece speaker)
- Earpiece Speaker (upper middle of frame)
- Vibrator motor (round silver part on right side of frame)
- Contact Flex cable (gold) and Rubber Gasket (black) for Loudspeaker (lower left)
- Headphone Jack (black, lower right)
Many “Display Assemblies with Frame” do not come with these items pre-installed. If you do not transfer these parts to your new display the phone will not function properly.
That's what I discovered. Could you please elaborate on how to remove those things? I am struggling with several.

So after some trial and error on a used K30 I bought off eBay, here is what I discovered on removing the remaining parts.
- the rubber parts came off pretty easily without the heat gun or any additional liquids, one just has to spend some time with tweezers/ their own hands pulling them off;
- I think the earpiece speaker was either weakly glued or not glued at all because it came off easily too, most of the trouble was getting it out, as was the loudspeaker, I may be misremembering or others may have it different though;
- the proximity sensor was not glued either;
- the headphone jack was glued, and though it was possible to remove it without a heat gun/ cleaning solution with a spudger after some effort, I recommend going with the heat gun/ hair dryer because there is a high risk of tearing off the rubber part on it (or at least a part of it came off for me);
- heat gun/ hair dryer required to remove the gold flex cable and the vibration motor, do not try to remove without prior heat application, also 1/2
you may face additional challenges when taking off the gold flex cable, as I struggled to remove it even after applying heat (or at least with the hair dryer, may be easier if you use the heat gun), I personally recommend the tweezers because other tools may scratch the surface, be careful not to stab it by accident (I did and now I am looking for a replacement). I also recommend starting to take it off from the lower left ending (with a golden square on it). Do not apply too much force.
One thing I noted is that the display's inner side had scratches on it, so I suspect I wasn't the first person to take the device apart, and my observations may not be universal. Some parts that weren't glued for me may be glued for you. If the rubber parts are glued, I'd suggest carefully applying an adhesive remover, for the rest apply heat. I would also advise removing the rubber parts before the electronics to avoid any possibility of the rubbers deforming, but feel free to correct me because I am not a professional.

I hope someone finds my observations useful. Though this is likely not enough to update the guide, I thought I'd share this so that maybe someone else uses it to come up with more comprehensive writings on the remaining parts, or in case someone is struggling from the lack of information like I did. As I said, I am not a professional repairs person (I am a programmer trying to learn phone repair), so I'd love to hear any suggestions/ corrections other people may come up with.
Overall, the repaired phone works fine, with my only concern so far being the scratching sound that happens alongside the vibrations whenever I try to call someone on Skype. I suspect this is due to the damaged cable and as I said, I am looking for a replacement.
And one more thing… To avoid damaging the parts, move the heat gun/ hair dryer around as you use it. I have heard warnings about damaged parts if one doesn't move it, so thought I'd share.

I just need to replace the front glass on the screen, not the entire screen. Will this guide work to do that?
Don't think so. This one just replaces everything with the frame. I watched a few other vids on YT on display replacement though, and some involved crushing the glass on the broken display along with the display itself to remove it from the frame, so I can assume it's very difficult to keep the display intact while removing the glass.

You forgot to mention to remove the SIM card. My card housing was bending up with the case inside the slot.

Thanks for mention that ! But you don’t have to take out SIM card or micro-SD card to remove just battery. We perform this task 3 to 4 times, all time battery and SIM card slot was safe. @Thomas_Tommy

There is a light adhesive around the edges so applying some heat to the plastic cover first (I use a hot plate at 80*c for about 5 minutes) and some alcohol along the edges will really help.
