Upgrading Dovado TINY to firmware 5.0.17

Customers with the Dovado TINY are advised to use the RESCUE utility to upgrade the router’s firmware beyond version 5.0.16. For this reason, you may notice that the usual ZIP version of the firmware is missing for 5.0.17 on Dovado’s firmware page (see above).

Firmware 5.0.17 addresses an issue causing some but not all TINYs to repeatedly power cycle a few types of USB modems, namely:

  • ZTE 110,
  • ZTE 190 and
  • Option Icon 505


These could be described as “cheapo” modems typically offered on pay-as-you-go deals. Dovado have explained that the power consumed by these modems can be particularly “spiky”, so an upgrade to the TINY’s bootloader was required to make the router more tolerant of this. Upgrading the bootloader is eqivalent to a BIOS upgrade on a PC, so the regular firmware upgrade is not enough.

Upgrade procedure

  1. Download the Upgrader application (available for Windows and Mac) from Dovado’s website
  2. Configure your ethernet connection (Local Area Connection) with a static IPv4 address: 192.168.1.128 (see below)
  3. Launch the Upgrader application and select the Rescue tab
  4. With the TINY connected via ethernet cable to your PC/Mac, hold the TINY’s reset button pressed while connecting the power
  5. Keep the reset pressed for 5 seconds – this puts the router into bootloader mode
  6. Click Rescue to initiate an upload of firmware 5.0.17
  7. Return your ethernet / local area connection to DHCP configuration
  8. Check the router configuration on http://192.168.0.1

How do I set a static IP address on my ethernet?

In Windows XP, right-click your Local Area Connection in your Network Connections and choose Properties. Scroll down through the list of items, select Internet Protocol (TCP/IP) and click Properties. Enable the “Use the following IP address” option and enter 192.168.1.128. A subnet mask of 255.255.255.0 will be entered automatically. Click OK to finish.

In Windows 7, click Start and type Network Connections to search programs. Choose View Network Connections and right-click the Local Area Connection to select Properties. Among the items select Internet Protocol Version 4 (TCP/IPv4) and click Properties. Enable the “Use the following IP address” option and enter 192.168.1.128. A subnet mask of 255.255.255.0 will be entered automatically. Click OK to finish.

When restoring the properties of your ethernet connection, choose the Obtain an IP address automatically option and be sure to select the Obtain DNS server address automatically option below as well, otherwise your internet connection will not work.

How can I be sure the TINY is in bootloader mode?

There are no obvious signs on the TINY or on the Rescue application that the esoteric press-and-hold manoeuvre on the reset button has successfully put the router into the special bootloader mode. However if it is not, the rescue will fail.
