Can Power Loss During a Firmware Update Brick the Ledger?

Views0

Power loss during a firmware update puts the device into Recovery Mode — not a permanent brick. Recovery is possible.

Why it's not permanent

Ledger firmware updates use a fault-tolerant bootloader. If interrupted, the device boots into Recovery Mode and waits for Ledger Live to reinstall the firmware.

Recovery steps

  1. Plug the device into a stable computer.
  2. Open Ledger Live — the Recovery prompt appears automatically.
  3. Follow the on-screen flow to reinstall firmware.
  4. After successful reinstall, restore accounts with the 24-word phrase.

Prevention

For laptops, run updates while plugged in. For phones, keep battery above 30%. Always have the phrase backed up before starting.

Safety reminder: Anyone asking for your recovery phrase or PIN is a scammer. Never enter the recovery phrase into software or webpages, use only official channels for updates and downloads, and migrate assets and report the incident immediately if anything looks off.
