There are four ways BLU update:

  1. Using recovery (to update installed OS)
  2. Using Fastboot (to recover BLU with Qualcomm SOC)
  3. Using Research Download (to recover BLU with Spreadtrum SOC)
  4. Using SP Flash Tool (to recover BLU with MTK SOC)

If you want to install a BLU update using recovery – download the official update, reboot your phone or tablet into recovery mode and click “Install update from SD card”.
