Dead DSL502T - When all LED's, except power, are out; even hard-reset/factory reset does not work. In my experience, it happens if you close the router configuration browser window midway while communicating with the router. i.e. you have opened 192.168.1.1 and before the page or a requested sub-page could load, you close the browser.
1. Download the firmware upgrade from this direct link or go to the support page,click on the firmware link and find DSL-502T download at the bottom of the window that pops up. Download and extract it with WinRAR
2. Connect the router to a LAN card on your computer.
3. If you are running a firewall, exit it / disable it / set it to allow all traffic.
4. Run the firmware upgrade utility, its an executable.
5. Check the "Corrupted Image Mode" option and click Next.
6. Follow the instructions to the word. (Don't exactly remember, but its something like this: the utility will tell you to power off the router and click "next" after 10 seconds. Then power on the router. The upgrade will then tell you a router IP. Something like, for example, your router IP is 169.1.8.1 set your machine IP to same subnet).
7. Open the TCP/IP configuration of the LAN card to which you have attached the router and set the IP address as told by the upgrade utility. In our example, router IP was 169.1.8.1, so assign 169.1.8.2 and enter the gateway as 169.1.8.1 to LAN card.
8. Run the upgrade utility again in exactly the same manner as before. If all goes well, your router will not only start working again but get an upgraded firmware too.
Remember:
1. Use these files/instructions at your own risk. My advise is, do not try this unless you have a dead router i.e. you have tried and failed even the factory-reset option. Thats when you have nothing to lose.
2. It worked on my router which had the factory default, flaky firmware. Dunno if it will work on already upgraded router.
3. Router settings saved earlier as .bin files (i.e. when the router was running normally on older firmware) will not work. You will have to enter the settings manually.
