Firmware package for the P-660HW-T1 router, hardware version 2, compressed into a 1.30 MB RAR. The size suits a complete ADSL modem firmware image, possibly with a boot or ROM file alongside it. Technicians use such images to revive a modem stuck in its bootloader, uploading over TFTP or via the debug serial port. Before flashing, compare the hardware version printed on the label with v2. Version 3 units use different firmware, and loading the wrong one can brick the device.
