SPI dump for the TP-Link TD-W8901G ADSL modem router, hardware version 3.4, read from an Eon EN25F16 flash chip. The EN25F16 holds 16 Mbit, equal to 2 MB, which the unpacked image should match. Repairers use a full flash copy like this to bring back units that stay with a constant power light after a failed firmware update. Read and keep the current chip contents first, then write with a programmer that supports Eon parts and verify the result before reassembling the modem.
