Actually, DON'T run particle update since you are running such an or firmware version. You will need to first update to version 5.5, then 7.0 then on to version 1.0.0. I believe there are instructions for that but I need to find them.
Electron 0.4.8 OTA upgrade warning
Whenever you upgrade from a version prior to 0.5.3, to a version after 0.5.3, you must always do an intermediate upgrade through 0.5.3. For example, if you upgrade from 0.4.8 (factory default) to 0.6.2, you need to upgrade first to 0.5.3, then upgrade again 0.6.2.The reason is that in 0.6.0 Electron system firmware changed from 2 to 3 parts. The intermediate upgrade is necessary as 0.5.3 has 2 parts, but knows how to install 3 parts.
The Safe Mode Healer knows how to do this, but if you upgrade OTA manually you need to do the intermediate upgrade yourself.
