The short version

What changed, and why it matters

This commit fixes a bug in Trezor hardware wallets where device settings stored behind the PIN lock were not reloaded after the user unlocked the device. The patch adds a call to reload settings from secure storage right after a successful PIN unlock. The included test checks that the auto-lock behavior still works correctly after unlocking. There is no public disclosure or CVE attached to this commit, and the vendor does not explicitly label it as a security fix.

Recommended action

Treat as a hardening or bug-fix patch and include it in the next firmware release. Review whether any user-facing security settings (e.g., auto-lock delay, safety checks, passphrase policy) could have been ignored or reverted to defaults before this fix, and consider adding regression tests for those specific settings after unlock.

Security signals we found

01

Settings loaded from encrypted storage only after PIN unlock

02

Missing reload could cause stale configuration to be used post-unlock

03

Auto-lock behavior is explicitly tested after unlock cycle

04

No explicit security framing in commit message or code comments
