More information:
TP-Link Archer C7 AC1750 WiFi router
Dual Band (concurrent) and Gigabit Ethernet. Advertised as 1750 Mbps. It has simultaneous Triple-Stream (3x3) radios on both 2.4GHz and 5 GHz Bands. It supports 802.11n in 2.4GHz for 450Mbps throughput and IEEE 802.11ac (draft) for 1300Mbps throughput in 5GHz.

TFTP Recovery (De-Bricking)

The serial-less TFTP recovery method for the TP-Link TL-WDR4300 also works for the Archer C7 (confirmed on v1.1 and v2) and the Archer C5 (v1.20).

For firmware revisions before 3.14.1 (140929), the router looks for an IP address of 192.168.1.66 and a file named ArcherC7v2_tp_recovery.bin. Firmware 3.14.1 updates the bootloader to look for an IP address of 192.168.0.66 and a file named ArcherC7v3_tp_recovery.bin even on hardware v2 units. Some v1.1 units may also look for ArcherC7v1_tp_recovery.bin. The model Archer C5 looks for the file ArcherC5v1_tp_recovery.bin.

To activate TFTP Recovery press and hold WPS/Reset Button during powering on until WPS LED turns on. Setup your computer to 192.168.0.66 (SubnetMask /24 = 255.255.255.0) and connect it to LAN1. Start TFTP server and provide recovery file with it.

For de-bricking with an OpenWrt image use the factory.bin image. :!: In case you are flashing back original firmware, make sure original firmware image name does not contain word boot → return_to_factory_firmware.

TFTP de-brick Alternative

Use the Cut file above and rename it ArcherC7v2_tp_recovery.bin
Change your Ethernet adapter to IP 192.168.0.66, subnet 255.255.255.0, gateway 192.168.0.1
Download Tftpd32 by Ph. Jounin at http://tftpd32.jounin.net/tftpd32_dow...
Browse to the directory that hold ArcherC7v2_tp_recovery.bin file.
Choose 192.168.0.66 for your "server interfaces"
Choose Tftp server tap
Activate TFTP Recovery press and hold WPS/Reset Button during powering on
Recovery using serial connection

Connect to your router via serial, power it up, then type "tpl" until the boot process is halted and you should be at the console. Set up a TFTP server with your firmware at 192.168.1.100, then run the following commands:

V1

The V1 is different because it only has 8mb flash not 16mb that the other version do.

tftp 0x81000000 [name of your firmware file].bin
erase 0x9f020000 +7b0000
cp.b 0x81000000 0x9f020000 0x7b0000
reset
V2

tftp 0x81000000 [name of your firmware file].bin
erase 0x9f020000 +f80000
cp.b 0x81000000 0x9f020000 0xf80000
reset
