Flash-Link Updater is only detected by FlashLink Manager in FLU mode?

+1 vote
Software: FlashLink Manager 4.36; Windows 10 Pro x64 version 1809

Hardware: Flash-Link Updater Ver.4, firmware 4.03

FlashLink Manager will not detect my Updater, unless I attempt to initiate a firmware update. Following that process, the firmware update gets stuck at 1%, so nothing happens. Canceling the update just puts me back to square one, with FL Manager stating that it is unable to detect the FL Updater.

The red power light is on, indicating proper power, and I have tried multiple USB ports and cables, even different computers. The Updater driver was installed correctly, and "FES FlashLink Device" appears in my Device Manager with no warnings.

The fact that the unit is detected when I try to update the firmware gives me hope that it is not defective, so can someone show me what I'm missing?

Unfortunately when the update stops at 1% and it is interrupted, the module is defective and it has to be replaced

Thank you for your response. I'll arrange a return/exchange with the seller.

you can try downloading this old version to relfash the firmware back into the flash link udpater


With NO unit connected to the Flash Link Updater

  1. Click on Help
  2. Click on FlashLink Firmware Update
  3. Follow on screen instructions to disconnect and reconnect 
  4. Go to Flash-Link Updater Updates tab
  5. Select and Flash the latest update.

If the flash works, once it is done, go back to Help , then click on Cancel FlashLink Firmware Update


This is a frustrating product and its functionality is not ready for primetime. This looks to be a very common issue with NO solution.
