I have managed to as well as several other people to have damaged my SmartWatch 2 (SW2) file system. The Unit boots but soon shows ‘FLASH FS’ issue on their devices. I have read back on other forums dated back to Jan/Feb ’14 that a possible solution was to use SUS (Sony Update Service) to detect and reflash the watch.

However from my experience I understand that today the support for SW2 was removed from SUS currently so I think the above solution is not possible. Does anyone know if there is a way (or backdoor way) to allow/force SUS to detect and reflash the watch without the need for Sony to redistribute the SW2 firmware (.dfu) publically?

  • How did you brick it? – weston Jun 09 '14 at 22:14
  • I was playing around with SUS and actually flashed MN2 firmware on it. I was planning to restore via dfu-utils and used the smartwatch.dfu on the developers.sony website and actually bricked it with this dfu firmware. I restore the boot from a previous memory dump, but need to restore the file system, but can't write from address 0x00000000 using dfu-util via the -s option. Sony don't have plans to share the dfu image for SW2, so last hope would be to restore via SUS if SW2 support can be enabled – user3714509 Jun 11 '14 at 07:03
