If you've got DFU-UTIL installed, and you're willing to give it a shot, you could try upgrading the system firmware.
Instructions, and files can be found here. You probably want to use the latest 0.4.4rc2 files. The commands can be found over at the 0.4.3rc2 release, where you'll have to correct the versions accordingly.
If you haven't got DFU-UTIL installed, but want to, here is a great guide to do so. Alternatively, here is a toolchain installer that will get you pretty much all software you could need for developing with Particle. CLI, Particle Dev, DFU-UTIL, Netbeans included.
Let me/us know if you need any further help/guidance.
