The honest guide, or no guide

Tested, not transcribed

Every guide is run on real hardware before it's published. If a tool has no Windows build, we say so — no fake .exe links.

Direct downloads

Latest versions, linked straight to the source. No signup walls, no crippled mirrors, no "download manager" traps.

Fixes included

Each guide covers the errors you'll actually hit — "Checking Target MCU", "Phased Out", "Could Not Find USB Device" — with the fix that works.
