  • Slow Flashing Speed: Over USB 2.0, flashing a 1GB system image could take 10–15 minutes. No USB 3.0 optimization.
  • No Modern Device Support: It will not work on Xperia XZ2 (2018) or newer. Sony switched to A/B partitions and standard fastbootd.
  • Learning Curve: For a new user, terms like "S1 boot", "TA partition", and "testpoint" are intimidating. A wrong flash (e.g., wrong loader.sin) could permanently brick older devices.
