A ZIP package of about 1.5 GB holding the engineering ROM, also labeled combination firmware, for the Xiaomi POCO M5 with the code name rock. Engineering firmware of this kind is typically used for service tasks such as testing hardware, enabling diagnostic modes or getting past certain locks, not for daily use. It is flashed with the chipset vendor's PC tools in the appropriate download mode. Confirm the device code name matches exactly, and back up the user data and calibration partitions before flashing.
