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.

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.

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

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.

That's what I discovered. Could you please elaborate on how to remove those things? I am struggling with several.

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.
