I received 8 new Electrons last week, and tried updating their firmware from 0.4.9 to 0.6.2. This worked fine for the first 5, but for the remaining 3 the process keeps failing on me.
I put the Electron in DFU mode, and run particle update in the Particle Cli. Even though it states '‘System firmware update successfully completed’, all 3 Electrons still remain with a 0.4.9 firmware.
Are there any fixes for this?
EDIT: Now all devices won’t accept any new firmware updates - ‘‘Invalid DFU suffix signature’’

Invalid DFU suffix signature
A valid DFU suffix will be required in a future dfu-util release!!!
After the ‘‘flash’’, the LED continues to show yellow. Firmware version remains unchanged
