Version (often shortened to “21013” in search shorthand) is a mid‑2021 release that struck a perfect balance for many users: it fixed critical bugs in the chip detection algorithm, improved CH341A high‑speed mode stability, and introduced better support for 64MB+ flash chips. Unlike later experimental builds (2.1.0.15+), which sometimes broke legacy chip definitions, build 21013 remains a “golden image” for technicians who prioritize reliability over new features.
Always backup your original BIOS/Firmware before attempting to write new data. Programming hardware carries the risk of "bricking" the device if done incorrectly. asprogrammer 21013 download extra quality link
