Firmware Version 5.0.8-00 for Zoom ADSL X6 Model 5590C/D/E/F

This firmware is only compatible with the Zoom ADSL X6 Model 5590C, 5590D, 5590E, or 5590F. You have a C, D, E, or F model version if the ETHERNET ports on the modem's back panel are color-coded yellow.

Important Notes

•If you get a Firmware Update Failed error ("Failed to write to system. Not enough core.") while attempting this firmware upgrade, you will need to load an interim code file and then re- apply the 5.0.8 firmware file, as explained in the steps below.

•You will be required to perform two hard factory resets on the Zoom ADSL X6, as described below. For this reason, please take note of your X6's Basic Setup settings as well as any configurations you have made on the Wireless and Advanced Setup pages. You will need to re-enter your settings manually after the modem has been upgraded.

•You must upgrade the firmware from a wired computer that is plugged directly into the X6.

How to Apply the Firmware Upgrade

1Connect a computer directly into the Zoom ADSL X6 modem/router via an Ethernet cable. Do not attempt to carry out the firmware upgrade over a wireless connection or through another router or network device!

2Unplug the DSL line from the back of the X6. Also unplug any Ethernet cables except the one for the computer on which you will be upgrading from.

3Close all running programs, including any instant messaging applications.

4It is recommended that you turn off any anti-virus and firewall/security software. Also disable the pop-up blocker feature in your web browser (or other application).

5Access the Zoom Configuration Manager by double-clicking on the Zoom icon on your desktop. If the Zoom icon is not there, then open your web browser and go to the X6's LAN IP address. By default this is http://10.0.0.2.

When prompted, enter the username and password. By default these are: User Name: admin

Password: zoomadsl (where "l" is a lowercase letter L)

6You must perform a hard factory reset on the X6. The hard reset procedure depends on your X6's current Firmware Version. You can find the current Firmware Version on the System Status page.

If your X6 has a 5.0.4-xx or later firmware version:

a On the X6's back panel, press and hold the RESET button for 2 seconds and then release.

b While the modem is going for reboot, the POWER light will turn red, ETHERNET will turn off briefly, and then WLAN and DSL will turn off. Please wait about 45 seconds, until the DSL light starts to blink again.

If your X6 has a 5.0.2-xx or earlier firmware version:

a On the X6's back panel, press the RESET button 7 times slowly (once per second). b Wait 10-15 seconds until the yellow and green ETHERNET port lights turn off briefly.

c Now look at the X6's front panel label. The POWER light will turn red and then the rest of the lights will turn off.

d Please wait about 45 seconds, until the DSL light starts to blink again.
