Ledger Wallet Cannot Open the Device｜Entry, Permission, and Screen Checks: practical reference notes for this topic (scope-specific to id=200204).
If Ledger Wallet cannot open the device, separate app state from connection path and device-screen state. The issue may sit in app entry, USB or Bluetooth path, system permission, or the current screen task. Checking these in order prevents repeated attempts from becoming unclear. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
Check app state first
Confirm the app opens from a stable entry and is not in the middle of an install or update question. If needed, return to Ledger Wallet Download and Installation Guide before continuing. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
Check connection path
USB and Bluetooth should be reviewed separately. If the PC path is being used, compare with Why Ledger Will Not Connect to a PC. If mobile pairing is involved, keep that note separate. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
Check permission and screen
System permission can prevent the app from opening the device. After each change, read the device screen to see whether the task is aligned with the app page. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
Record the next step
The note should include app version, device model, connection path, permission state, and visible screen. It should not include PIN or recovery phrase details. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
If the app opens the device after a permission or cable change, record that layer. If it still does not, the next review should start from the same four fields instead of restarting randomly. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
The useful answer is a repeatable order: app entry, connection path, permission, device screen, and non-private record. (id=200204 scope-specific note for "Ledger Wallet Cannot Open the ")
