Ledger Nano (or HW.1) update is not successful

This section applies to the following products:

  • Ledger Nano (not Nano S)
  • Ledger HW1

We have been reported very few cases of update fails. However, if you ever encounter some glitches: do not hesitate to restart the process, or to plug/unplug the Nano 10 times if you are asked to. Even if it fails in the middle, or if you unplug the Nano by accident while flashing the firmware, you'll be able to recover.

 1/ On Linux, you may be stuck with a not recognized device: make sure that you do have added the line

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="3b7c", MODE="0660", GROUP="plugdev"

in the file


and that you executed:

sudo udevadm control --reload-rules

 2/ On some instances of Windows 7, the Nano is not recognized anymore during the update process. We are looking for a fix, but right now if you are in this situation you must finish the update on another computer (Mac, Linux, Windows 8...). Once the update is done, your Nano will successfully be recognized on Windows 7.

3/ On other OS, you can try to force the update by going to https://fup.hardwarewallet.com/ and following the process after having made sure you checked the drivers and installed the Chrome extensions.
