    Your question reminded my immediately about one of my favorite 35c3 talks Butterbrotdosen-Smartphone - Mein DIY-Smartphone-Bau from 2018-12-29. It is in German language, but has an English translation, too. Maybe it can give you some good starting ideas?

    Video: 1080p

    Story, Translated with DeepL.com (free version)

    I would like to show you how I built a smartphone from a Raspberry PI. The problems and difficulties I encountered and the solutions I found. The project is not yet finished, there are still a few small things missing. Nevertheless, I want to show you my smartphone in the practical sandwich box and tell you how it came about.

    I had no idea that building a smartphone could be so complicated. Raspberry Pi + touch display is not all there is to think about in this project. At the moment, the smartphone project lives in a sandwich box and attracts attention on the subway. If the power bank can passthrough, that’s an advantage, I’ve found. Setting up the X and Y axes on the touch display so that you can also use the on-screen keyboard was not so easy. And I had to realize that Landscape is not the right size to work smoothly. Most Linux programs are not directly touch-compatible or require too much memory. Then there were also big challenges! Learning to solder was one of them. First learning how to solder, then learning how to desolder, and then daring to use the PI. I would like to tell you these and other stories about building my smartphone.

    Genaus so ein “Puzzle” hatte ich damals vor mir liegen, aber dank der Photos und ein bisschen Ausprobieren fanden alle Teile (auch gehüpfte Federn) wieder ihren korrekten Platz.

    Bei mir hat die Bohrer-Methode immer gut mit meinen normalen Metallbohrern funktioniert. Es gibt anscheinend aber auch spezielle "Schraubenausdreh"bohrer, die u.a. sich beim Auf-/Linksdrehen nicht aus der Schraube drehen.

    Mein Vater würde übrigens einfach eine Schraube auf die Schaube schweißen (wenn die Schraube geeignet ist) und dann mit Zange oder Schraubendreher herausdrehen. Damit habe ich aber nur Erfahrung als Zuschauer 😆

    Hope I have interpreted the photo correctly and this is just a metal screw, that has become to round to be screwed out with a hex wrench.

    In such case, I use a drilling machine to carefully drill a small metal-suited drill a few millimeters into the screw. Then I remove the drilling machine and hold the drill (still in the screw) with combination pliers (or similar pliers) and unscrew the metal screw (again carefully).

    I hope my translation of the tool names are close enough to understand what I mean :)

    In German it would be: Einen Metallbohrer mit Bohrmaschine einige mm in die Schraube bohren, dann mit Kombizange den Bohrer festhalten und zusammen mir Schraube herausdrehen.

    EDIT: also please be careful when opening up the keyboard and document your steps with photos. When I repaired a 80s Korg some years ago, there where many parts that could spring out of place, e.g. when lifting the keys.

    Definitely dislike MS, generations of my workstations have small, yellow “Microsoft Free Workstation” stickers on their monitors, but VSCodium (in my case) is not really bad.

    Also I really like the Xbox360 console and (as a hacker and maker) still love the first Kinnect. The Kinnect is an excellent piece of sensor-hardware, was rather cheap when purchased in used condition and it works very well with Linux.
