Ledger firmware 2.3.0 should be read as a dated product update, not as a current-latest instruction by itself. The useful reading path is to identify the official source, check which device and app state the note refers to, then compare that with the Ledger Wallet prompt and the Ledger device screen available to the user now.
Start from the source and version context
Record the source page, version name, publication context, and the device family mentioned by the update. A firmware article can remain useful after time passes if it clearly separates the dated note from the current device prompt. Do not copy an old version note into a current action without checking Ledger Wallet first.
For the basic distinction between app updates and firmware updates, read app updates vs firmware updates. That helps keep software-layer and device-layer prompts separate.
Use Ledger Wallet to confirm the current device prompt
Firmware work should be started from Ledger Wallet through a fixed app entry. If Ledger Wallet does not show a matching device prompt, the dated article should stay a reading reference rather than an action guide. If it does show a prompt, read the device screen before continuing and keep the device connected in a stable environment.
The Ledger Wallet download guide is the stable entry reference when the app path itself needs to be checked before an update.
Keep device-screen confirmation in the update path
The device screen matters because firmware work belongs to the device layer. Read the prompt on the device, compare it with the app state, and avoid changing several conditions at once. If a connection issue appears after an update prompt, use post-firmware connection checks to separate cable, platform, permission, and app state.
Finish with an update record
The record should include version name, source path, app version or app state, device model, device-screen state, and next step. It should not include recovery words, PIN details, or private backup photos. This keeps the 2.3.0 article useful as a version-reading reference while leaving current action decisions to Ledger Wallet and the device screen.
