Up-param.bin -

up-param.bin is a proprietary binary configuration file most commonly associated with the NVIDIA Shield TV series (and related Android TV set-top boxes utilizing the Tegra family of SoCs). It is utilized by the system's bootloader or low-level initialization daemons to configure hardware parameters prior to the full boot of the Android operating system.

If structure looks like TLV or fixed structs:

If evidence of protobuf/flatbuffers:

If compressed:

# Example only — adapt offsets/sizes after inspection
import struct
data = open('up-param.bin','rb').read()
header = struct.unpack_from('<4sB I', data, 0)  # e.g., magic(4), version(1), length(4)
print(header)
