TP-Link EAP245 v1 is an AC1750 (802.11ac Wave-1) ceiling mount access point.
Device specifications:
* SoC: QCA9563 @ 775MHz
* RAM: 128MiB DDR2
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (SoC): b/g/n, 3x3
* Wireless 5Ghz (QCA9880): a/n/ac, 3x3
* Ethernet (AR8033): 1× 1GbE, 803.2at PoE
Flashing instructions:
* Extract /usr/bin/uclited from the device via ssh and apply the binary
patch listed below. The patch is required to prevent `uclited -u` in
the last step from crashing.
* Exploit the user management page in the web interface to start telnetd
by changing the username to `;/usr/sbin/telnetd -l/bin/sh&`.
* Immediately change the malformed username back to something valid
(e.g. 'admin') to make ssh work again.
* Use the root shell via telnet to make /tmp world writeable (chmod 777)
* Copy the patched uclited programme back to the device at /tmp/uclited
(via ssh)
* Upload the factory image to /tmp/upgrade.bin (via ssh)
* Run `chmod +x /tmp/uclited && /tmp/uclited -u` to flash OpenWrt.

Debricking:
* Serial port can be soldered on PCB J3 (1: TXD, 2: RXD, 3: GND, 4: VCC)
* Bridge unpopulated resistors R225 (TXD) and R237 (RXD).
Do NOT bridge R230.
* Use 3.3V, 115200 baud, 8n1
* Interrupt bootloader with by holding CTRL+B during boot
* tftp initramfs to flash via Luci web-interface
Tested on the EAP245v1 running the latest firmware (v1.4.0). The binary
patch might not apply to uclited from other firmware versions.
