How to Update the A317 MCU

Flashing the A317 MCU

The Micronet A317 MCU can be updated in two ways:

  1. SD Card
  2. OTA with RedBend

NOTE: These methods will perform a factory reset on the device. All applications and data will be erased.

SD Card

  1. Insert the SD card into the SmarTab’s SD card slot with the MCU.s19 and flash_all_mmc.scr obtained from Micronet.
  2. Press and hold the red decline button and the center circle enter button until you see the bootloader flash screen shown below


  1. Once everything besides the logo reads “OK” you can power the device off, take the SD card out, and then power the device on.
  2. Verify that the MCU was updated by checking “Settings”  “About Phone”  “MCU Version”
