Scope at a glance

Compatibility matrix

The searchable firmware catalog is the canonical model / control-board / NAND / filename / size / SHA-256 matrix.

Verified public scope

47 model families, 75 exact NAND routes and a published SHA-256 for every build. Confirm the board-specific recovery route before installation

Install implications

Use the exact model + board + NAND route; record the baseline, verify the archive, confirm first boot and keep recovery status visible. Confirm board-specific persistence and reset behaviour with support before proceeding.

Known limitations and non-goals

Web, Toolkit, SD and recovery are not catalogued install alternatives. No universal performance, warranty, safe-limit or automatic-rollback claim is made.
