NOTES

  • Lenovo provides a "Product Maintenance Manual" on the support page, this manual shows how to open the device and how to use the RSA mentioned bellow.
  • RX and TX pins for serial debugging are clearly marked on the mother board.
  • Rescue and Smart Assistant (RSA), known as "Software Fix" on the product support page, can be used to flash the latest stock firmware, including recovery and boot, thus can be used to recover bricked devices, see "Product Maintenance Manual". NOTE: The Lenovo RSA only runs on Windows and requires an account.
