Technical design
Do Not Power Off:
Do not turn off the router or disconnect the cable during the update process.
- Backend: Query TP‑Link firmware API or scrape vendor downloads with caching and TTL (e.g., 24h).
- Firmware delivery: HTTPS with strong TLS and certificate pinning to TP‑Link domains.
- Integrity checks: SHA256 hash + optional PGP/RSA signature verification if vendor-signed builds available.
- Local validation: verify model/hardware version metadata embedded in firmware binary before flashing.
- Atomic install: write to inactive partition slot, then switch boot pointer (A/B partitioning) to enable rollback.
- Rollback window: track previous firmware image and configs for N (e.g., 10) minutes post‑update for auto-rollback.
- UI: responsive web UI integrated into router admin; accessible fallback via CLI (for advanced users).
