The short version

What changed, and why it matters

This commit tightens the rules between a Trezor device's PIN and its 'wipe code' (a special code that erases the device). Previously, it was possible to end up in an inconsistent state: for example, you could set a wipe code even when no PIN was set, or remove the PIN while the wipe code was still active. The patch blocks both situations and shows explanatory on-screen messages. It also replaces some internal 'assert False' statements with explicit error raises, which is a defensive cleanup. The change is a hardening fix rather than a remote exploit.

Recommended action

Treat as a low-to-moderate hardening improvement. Review whether the new RuntimeError paths are handled correctly by host software and do not leak internal state. Verify that the translated strings are signed and included in production translation blobs. No urgent user action is required.

Security signals we found

01

New guard condition prevents PIN removal while wipe code is active

02

New guard condition prevents wipe code creation when PIN is not set

03

Replaced assert False with raise RuntimeError in unreachable error paths

04

Added user-facing explanatory popups for both blocked operations

05

Tests updated to assert Cancelled/TrezorFailure for the newly blocked flows
