TP-Link AC2600 Dual Band Mesh WiFi Range Extender (RE650 v2.0) SPI Flash Dump

I accidentally bricked my TP-Link WiFi range extender whilst attempting to install OpenWrt, leaving it inaccessible via TFTP or a wired serial connection. With no other recovery options available, I ultimately purchased a replacement.

To help others in the same situation, I used a CH341A USB Programmer to dump the SPI flash chip (W25Q64JV) from the new range extender prior to powering it on for the first time. This way, anyone facing a similar issue can re-flash their device instead of having to purchase a replacement.

• Device Model: TP-Link AC2600 (RE650 v2.0)
• Firmware Version: 1.0.4 Build 20210907 Rel. 71667(6585)
• SPI Dump SHA256: f1ac8c5c880ade366a89f494aa874906c7e160d9e51e8030c6865bf388db1588
