Specification: SoC: MediaTek MT7628AN RAM: 128M DDR2, ESMT M14D128168A (2Y) Flash: 32M, cFeon EN25QH256A (Dual Boot on OEM, concatenated on OpenWrt, SPI) Switch: MediaTek MT7628AN, 3 ports 100 Mbps WiFi: MediaTek MT7628AN 2.4 GHz 802.11n USB: 1 port USB 2.0 GPIO: 1 button (Wi-Fi & Reset on OEM, Reset on OpenWrt), 3 LEDs (Power, Internet, Wi-Fi), USB port power controls Disassembly: There are 2 screws at the bottom near the LEDs hidden by rubber mounts. After removing the screws, pry the gray plastic part around (it is secured with latches) and remove it. UART Interface: The UART interface can be connected to the 5 pin located between LAN ports and the WAN one. Pins (from the second LAN port to the WAN one): VCC, TX, RX, NC, GND Settings: 115200, 8N1 Flashing via TFTP: 1. Connect your PC and router to the first LAN port, configure PC interface using IP 192.168.1.2, mask 255.255.255.0 2. Serve the firmware image (for OpenWrt it is *-squashfs-factory.bin) renamed to KN-1221_recovery.bin via TFTP 3. Power up the router while pressing Wi-Fi button 4. Release Wi-Fi button when Power LED starts blinking To revert back to OEM firmware: The return to the OEM firmware is carried out by using the methods described above with the help of the appropriate firmware image found on osvault.keenetic.net. When using OEM bootloader, the firmware image size cannot exceed the size of one OEM «Firmware_x» partition or Kernel + rootFS size.
