How to Run a Ledger Firmware Update|Entry, Screen, and Completion: practical reference notes for this topic (scope-specific to id=200403).
A firmware update should be run in an ordered flow: stable app entry, version prompt, device screen, and completion record. Changing cables or settings during the flow should be avoided unless the app state requires a connection check. (id=200403 scope-specific note for "How to Run a Ledger Firmware U")

Open from a stable app entry
Start from a known Ledger Wallet entry and confirm the app is ready. If the app entry is the question, use Official App Download and Installation Guide. (id=200403 scope-specific note for "How to Run a Ledger Firmware U")
Read the version prompt
Write down the version prompt before starting. This keeps the update record tied to the actual version shown in the app. (id=200403 scope-specific note for "How to Run a Ledger Firmware U")
Follow the device screen
Do not rely on the computer screen alone. Read the Ledger device screen at each confirmation point and keep the task aligned. (id=200403 scope-specific note for "How to Run a Ledger Firmware U")
Record the final state
After completion, record app state, device screen, model, and version. If connection does not return as expected, continue with After a Ledger Firmware Update. (id=200403 scope-specific note for "How to Run a Ledger Firmware U")
