Check Whether Work Is Waiting or Already Running
When a Ledger Live device-app install stays at zero percent, look at the Ledger screen before starting more installs. The current host name is Ledger Wallet. Zero on the host does not establish whether the request is waiting for unlock, awaiting secure approval, unable to fetch required data, or failing before device installation begins.
Also verify that the operation is a coin-app installation rather than a Ledger OS update. Preserve any actively progressing hardware maintenance. Do not apply an ordinary idle-session restart to an advancing firmware installation.
Read the Prompt and the Error Together
Unlock the device on its own controls if requested, then follow the current management screen. Approve only the expected connection or installation flow. If the hardware requests an unrelated payment or unfamiliar signature, reject it rather than treating financial approval as an installation requirement.
Ledger’s secure-channel documentation distinguishes required user interactions from installation progress. This is useful context: a numerical progress indicator is not a complete account of what the workflow is awaiting.
Check Capacity and Compatibility Before Retrying
If My Ledger reports insufficient device storage, use the model’s normal app-management controls to free appropriate space. Computer disk cleanup does not increase the signer’s app capacity. Retain the initialized wallet and avoid a hardware reset.
If the requested app requires a different supported device OS, follow the current maintenance order. Ledger’s app-update reference explains how old device firmware or app dependencies can prevent the necessary coin-app release from being available. Changing cables or using a faster network cannot remove that OS compatibility requirement.
Test the Management Path Without Adding Requests
Does the device remain identified, and can the installed inventory load? If recognition disappears first, investigate the supported local transport and host permissions. Close competing wallet clients when the hardware is idle. On the dedicated desktop client, use a stable USB data connection.
If recognition remains but catalog retrieval or installation returns an online error, check its exact wording. Ledger’s status dashboard can show relevant incidents, while a trusted permitted connection comparison can reveal network-specific behavior. Keep certificate validation and normal protection enabled during that investigation.
For example, an acknowledged management connection followed by a certificate-chain error on office Wi-Fi calls for proxy or inspection review. Repeatedly removing and reinstalling the same coin app does not test that network cause. If the catalog itself never loads, resolve catalog access before treating the zero-percent label as a device write failure.
Confirm the Actual Outcome Before Another Attempt
Once the previous operation has finished or explicitly failed and normal device access is available, inspect the hardware’s app list and refresh the host inventory. A stale final screen may not reflect the current installed state. If the app is already present, use its relevant supported operation instead of queuing another installation.
If it remains absent, retain the error and resume only through the official current install flow. Make one deliberate attempt after addressing the identified condition. Persistent unexplained zero-percent failures belong with official support, with the observed stage and versions included.
How Long Should I Wait at Zero?
There is no universal timeout covering every model, host, and request. Read progress on both screens and use the current instructions for the actual state. Avoid inventing a fixed disconnect threshold.
Should I Download the App Binary Separately?
Use the official supported catalog for ordinary installation. A firmware blob, unsigned developer app, or privately supplied package is not a routine repair for a stalled consumer workflow.
Will This Require My Backup Words?
Coin-app installation does not require entering recovery words into the host. Support needs the app name, model, software versions, device text, error, and relevant connection comparisons instead.
