THIS INSTRUCTON WILL NOT WORK FOR UNIFY PRODUCTS! FLASHING THESE UNITS VIA THE GUI IS A ONE WAY STREET!

INITIAL FLASH:
-install latest airos/ubnt firmware first
-reset to defaults
-flash to DD-WRT as mentioned in the dl folder for your device and/or read the RECOVER instruction below. be sure to use the correct file!
-DD-WRT will be at 192.168.1.1

UPGRADE DD-WRT:
-via web-if

RECOVER & INITIAL FLASH:
from the orig ubnt recovery manual
Code:
Requirements:

    * Direct ethernet cable connection between PC and LiteStation
    * Network settings of PC: 192.168.1.254/255.255.255.0
    * TFTP client on PC
    * firmware file to flash

Recovery procedure

   1. First of all, power off the device.
   2. Power it on and keep on holding reset button for ~10 seconds (do not hold it longer!)
   3. If your device has been already upgraded to v1.5 before, RDY LED should be lit, indicating that device is ready for recovery
   4. Make sure LiteStation responds to pinging (ping 192.168.1.20), if it does not, go to step 1
   5. rename firmware file into flash_update (not necessary since v1.5 firmware!)
   6. using TFTP client software, upload flash_update to 192.168.1.20 in binary mode
   7. Signal LEDs will be blinking during firmware upgrade (since v1.5 firmware!)
   8. wait for about 7 minutes on LiteStation2 (to be safe) - do not power off the device during procedure! LiteStation5 upgrade takes less time.
   9. device should be alive by now

Example of steps 4-5:

Here is log of the steps 4-5 from Linux terminal:
