Ubiquiti LiteBeam M5

Hardware Highlights

Installation

→ Install OpenWrt (generic explanation)

Unsuccessful Procedure

  1. Flashing via ubnt GUI: failed to accept any FW lower than XW.v6.1.3. “Firmware image check failed. Error code: 43”
  2. Flashing via SSH: using ubnt fwupdate.real command failed to accept any FW lower than XW.v6.1.3
  3. Flashing via TFTP: did accept FW lower than XW.v6.1.3 but with “Initialization Error A12”.

Successful Procedure

I installed the “cs” custom scripts versions of AirOS in this order

  1. via AirOS GUI or SSH: Downgrade from XWv6.1.7 to XWv6.1.4
  2. using TFTP downgrade to XW.v6.1.3
  3. then OpenWrt 19.07.x factory (this process must be done via TFTP).

Flash Layout

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

Flashing via TFTP method

First, you need to put LiteBeam M5 into TFTP server mode. Turn on LiteBeam M5 and keep the reset button pressed for 20 seconds until LEDs light start flashing differently. When you see that odd and even wifi signal LEDs start turning on and off, you have successfully put LiteBeam M5 in TFTP server mode.

You need a TFTP client that will send the file to LiteBeam M5. A Simple Windows GUI TFTP Utility (tftp2) can be used.

Now you can send image from your PC to LiteBeam M5 using command prompt. The server is running on 192.168.1.20 address by default.

If you are running Linux on your PC here is how you can send firmware image to LiteBeam M5: 

ifconfig eth0 192.168.1.254
cp  openwrt-ar71xx-generic-ubnt-litebeam-m-squashfs-factory.bin code.bin
echo -e "binary\nrexmt 1\ntimeout 60\ntrace\nput code.bin flash_update\n" | tftp 192.168.1.20

Upgrading OpenWrt

→ generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

LuCI Web Upgrade Process

  • Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

Terminal Upgrade Process

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Debricking

→ generic.debrick

Recover stock firmware flashed with airos 5.6 or higher

Requirements:

  • 1 USB-TTL Cable
  • 2 Ethernet Cables
  • 1 POE Converter
  • 1 Bricked Device
  • 1 TFTP Server Application (Example: Solar Winds)
  • 1 AirOS v6.1.7 Firmware File
  • Tera-term or another Serial Port program

The following is the Procedure to unbrick the device:

  1. Open up the device and locate the serial jumper, labeled J1.
  2. Connect the USB-TTL Cable to the jumper, which has the following pinout:
    • 1 3.3V+ (Red: Do not connect)
    • 2 S-in (GREEN)
    • 3 S-out (White)
    • 4 GND(Black)
  3. Open up a terminal program, such as tera-term, and configure it to the following settings:
    • Bits per second: 115200
    • Data Bits : 8
    • Stop Bits : 1
    • Parity : None
    • Flow control : None
  4. Plug the POE adapter into the wall.
  5. Plug the LAN side of the device into your PC.
  6. Configure your PC IP settings to the following:
    • IP Address: 192.168.1.123
    • Netmask : 255.255.0.0
  7. Connect the POE side of the POE adapter into the Litebeam M5 (or any other AirMax device).
  8. Continually press any key while the tera-term window is selected. Doing this will interrupt the boot sequence and allow you to enter terminals while the device is in the bootloader.
  9. Once the boot has been stopped, enter the following into the terminal: 
    urescue -f -e

    It is vital that the -f and -e are there. This allows the bootloader to be over written.

  10. Now start the TFTP application on your PC.
  11. Open a command prompt on your PC and use the cd command to navigate to the location of your AirOS v5.5.10 firmware file.
  12. Type the following command in the command prompt: 
    tftp -i 192.168.1.20 put XM.v5.5.10.24241.141001.1649.bin
  13. You should now see text being written in the terminal screen.
  14. Keep watching the text until it says the device is resetting. When it does reset, continually press any key to interrupt the boot.
  15. When the boot has been interrupted, type the following in the serial console, pressing enter after each line: 
    mtdparts default
 
saveenv
 
boot
  16. The device will now boot. Wait about 2 minutes, and then access the webpage of AirOS by typing 192.168.1.20 in the web address bar.
  17. Login to the page and navigate to the system tab. Upload the same firmware version, AirOS v5.5.10, that you used in the urescue command.
  18. Once the device reboots you will have a non-bricked, perfectly functional, wireless device.
