Firmware dump from a Tenda AC1200 wireless router, hardware version 1, stored in a 6.66 MB RAR archive. A full flash dump like this restores a router bricked by a failed update, written back with an SPI programmer to the board's flash chip. Check the extracted image size against the chip capacity, and read your own chip first, since dumps can contain MAC addresses and calibration data specific to one unit. Confirm the hardware version on the router label matches v1.
