Firmware for the TP-Link TD-W8901N ADSL modem router, hardware version 3.0, stored in a 2.66 MB RAR archive. The hardware version on the router label matters, because images for other versions are not interchangeable and can brick the unit. Such firmware is used to recover a router stuck in a boot loop or with a corrupted flash. It can be loaded through the web interface or a recovery method, or written straight to the flash chip with a programmer. Dump the existing chip before overwriting it.
