What it is (quick overview)
Redmi Note 13 Pro (garnet) Keep NV engineering factory firmware rom is a service/diagnostic build used by technicians to validate hardware and radios. The Keep NV variant is designed to preserve NV/EFS (IMEI-related provisioning, radio calibration) during recovery or troubleshooting.
Bootloader & AUTH rules (read first)
- Bootloader locked (BL locked): You cannot flash any engineering/factory package yourself. Writing this firmware on a locked device requires an authorized service (AUTH) account and EDL access. You also cannot unlock the bootloader from EDL without proper authorization.
- Bootloader unlocked (BL unlocked): You may flash via Fastboot using a package that explicitly states Keep NV. Do not relock while running engineering firmware; relock only after returning to verified retail HyperOS/MIUI.
Safe flashing outline (short)
- Charge ≥50%, install platform tools and correct drivers.
- Back up NV/EFS before any operation.
- Flash with Fastboot (BL unlocked) using the Keep NV script, or with EDL + AUTH at a service center if BL is locked.
- Boot, run factory tests (sensors, display, audio, cameras) and radio checks (cellular/Wi-Fi/BT).
- When done, flash retail firmware; then relock if needed.
Notes & cautions
- For service use only; not intended as a daily driver.
- Expect verbose logs/test menus; performance and battery may differ from retail.
- Keep NV aims to preserve modem data, but a backup is still essential.
- Respect owner consent, warranty terms, anti-rollback/region policies.
