However, the technical competence of a utility is not solely a function of features. Reliability depends on rigorous testing across devices, robust error handling, clear documentation, and transparent release processes. Community-developed tools can vary wildly by these measures. A tool that works reliably on one hardware revision or firmware build can still brick another. Moreover, the crucial low-level operations K-dcan performs—rewriting bootloaders, modifying radio firmware, changing persistent identifiers—are intrinsically risky. They demand conservative defaults, explicit user confirmations, and safeguards against accidental or malicious misuse.
