Engineering firmware for the Xiaomi Redmi Note 5 Pro, codename whyred, packed in a 1017 MB RAR. The name says it is for E7S hardware, flashed in EDL mode, keeps NV data and lacks band 28 (NoB28). Engineering builds are typically used to bypass locks, repair IMEI or recover dead units via Qualcomm EDL with QFIL or MiFlash. Keeping NV means calibration should survive, but still back up the modem partitions first, and confirm your device is whyred with matching hardware variant.
