I have bought my speedict from Speedict Technology LTD. in Hong Kong and it was in use since 05/2011 and wanted to do a firmware upgrade, but this failed, now no firmware is installed. I also have tried to reinstall the last working firmware 2.0 but even this failed.
Now, is it dead or what could I do? Please help!
recently we have received firmware upgrade issues e.g. upgrade failed and need to re-install speedict usb driver, need 2 to 3 attempts and re-install usb driver to complete the upgrade process.
the problem (need to re-install usb driver) was caused by windows' plug&play, during firmware upgrade speedict ebike need to reset its usb port (for new code replacement) therefore you will hear "dong dong" sound when your usb still connected to speedict ebike (act like you unplug and plug in usb, you will hear such dong dong sound), however if windows plug & play has problem, speedict ebike can not detect usb again, it will prompt error ... when manually unplug and plug in usb again and speedict ebike detected usb then will continue the rest of upgrade process, because of entire upgrade process the usb need to be reset twice (depend on firmware version) so after few manual unplug and plug work, the upgrade complete.
i have windows 7 32 bit installed on my mac via virtual box, i have got same issues at first, on virtual windows 7 when usb is detected i need to tell virtual machine the usb is either for mac or windows system however the default go to mac os x system, so during firmware upgrade, whenever usb is reset and the usb p&p set usb host to mac os x ! i then by configured virtual machine the default speedict usb host to windows 7 the problem solved.
