📱 Flash Samsung Firmware on Linux (Ubuntu 24.04+) Using Heimdall

A complete step-by-step guide to flashing Samsung firmware using Linux and the open-source Odin alternative: Heimdall.

🧰 Requirements

A Samsung smartphone or tablet
A Linux distro (tested on Ubuntu 24.04)

Random Spreadtrum and Unisoc Tools

I got on a journey to unlock Spreadtrum Unisoc device last week. I'm used to flashing MTK and Qualcomm device, my research so far is listed here:

Bypass Windows 11 Upgrade Assistant / Setup Hardware Checks (TPM, CPU, RAM)

This PowerShell script allows you to bypass TPM 2.0, unsupported CPU, and memory checks enforced by the Windows 11 Upgrade Assistant and setup.exe from Windows installation media. It eliminates common upgrade blocks such as:

This PC doesn't currently meet Windows 11 system requirements.
TPM 2.0 must be supported and enabled on this PC.
The processor isn't currently supported for Windows 11.

What It Does

$ ioreg -p IOUSB -w0 | sed 's/[^o]*o //; s/@.*$//' | grep -v '^Root.*

Example ouput:

USB 2.0 BILLBOARD

Stream.sh

stream.sh is a Bash script designed to stream multiple video sources to multiple screens using ffplay. This script ensures that each video stream is displayed on a specified monitor and restarts the stream if it fails. The script is optimized for real-time playback by using various ffplay options to reduce latency and handle frame drops effectively.

Features

Streams multiple video sources to multiple screens.
Ensures each stream is displayed on the specified monitor.
Restarts streams automatically if they fail.
Optimized for real-time playback with minimal latency.

During the past days, this great article by Sam Pruden has been making the rounds around the gamedev community. While the article provides an in-depth analysis, its a bit easy to miss the point and exert the wrong conclusions from it. As such, and in many cases, users unfamiliar with Godot internals have used it points such as following:

Godot C# support is inefficient
Godot API and binding system is designed around GDScript
Godot is not production ready

In this brief article, I will shed a bit more light about how the Godot binding system works and some detail on the Godot

	Hello all UPDD users,

	I found a better solution to reinitialize the UPDD daemon without non-macOS tools.
	It is tested with the UPDD version 6.00.771 on Mavericks and Mojave.

	Before installing the driver, I set the date to 01-01-2038, the UNIX End-Of-The-World-Date.
	I'm not sure if this made any difference, but I did it.

	This is the shell script to use:

	#!/bin/bash

	set -e

	# This script creates a patched boot.img with KernelSU GKI kernel and cmdline tweaks

	SCRIPT_PATH="$(dirname "$(realpath -s "$0")")"
	MAGISKBOOT="$SCRIPT_PATH"/magiskboot
	MAGISK_VER="v26.1" # used for downloading magiskboot, newer versions print "unexpected ASN.1 DER tag: expected SEQUENCE, got APPLICATION [1] (primitive)" warning(?)
	ANYKERNEL_FILE_NAME="CHANGE_ME" # for downloading from the latest KernelSU github release, e.g. "AnyKernel3-android13-5.10.157_2023-03.zip"
