TP-Link EAP225 v1 is an AC1200 (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, 2x2
* Wireless 5Ghz (QCA9882): a/n/ac, 2x2
* Ethernet (AR8033): 1× 1GbE, 802.3at PoE
Flashing instructions:
* Ensure the device is upgraded to firmware v1.4.0
* 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)
* 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.
* Copy the patched uclited binary 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 install OpenWrt.

To make sure the correct file is patched, the following MD5 checksums
should match the unpatched and patched files:

Debricking:
* Serial port can be soldered on unpopulated 4-pin header
(1: TXD, 2: RXD, 3: GND, 4: VCC)
* Bridge unpopulated resistors running from pins 1 (TXD) and 2 (RXD).
Do NOT bridge the pull-down for pin 2, running parallel to the
header.
* Use 3.3V, 115200 baud, 8n1
* Interrupt bootloader by holding CTRL+B during boot
* tftp initramfs to flash via the LuCI web interface
setenv ipaddr 192.168.1.1 # default, change as required
setenv serverip 192.168.1.10 # default, change as required
tftp 0x80800000 initramfs.bin
