Mine is now going into TFTP mode so vague signs of life.

However whenever I try to send the firmware I just get timeout. I tried the original firmware TFTP client as well as the Firmware Upgrade tool, no joy with either.

Any ideas?

So I eventually managed to get the firmware on. I had to use 3 of the TFTP clients, one worked with the RST firmware (the original old one), and one worked with the .all firmware.

So I put the RST on, the router booted (the second time, the first time it went on but could not access it using HTTP). Interetingly when I put the .all on it again, it immediately bricked it AGAIN! So this is repeatable for my unit.

Now running with .RST and it is not stable however - got ADSL up but after 30 mins or so it just dies and has to be rebooted.

I am going to RMA it.

Jeez

I wish I had read the forums BEFORE I tried to upgrade my Vigor

I now have a brick as well - same model, same process

Has anyone ever had a good result from this?

Thank you for all the ideas up top

I was getting the exact same response (timeout) on my unit when I tried to use the Draytek tftp client to upload new firmware using the tftp boot.

However, on a whim, I thought, hold on, if it is timing out, how about if I use a faster port? So I plugged into the gigabit LAN port instead of the other ones I had been trying and it worked.

So for me, as a summary of what worked, here it is:
While connected to the internet:
1) Read forums first - then upgrade firmware !!
2) If you have bricked the Vigor, download the Draytkek tftp server from
http://www.draytek.co.uk/support/download/tftp302.zip
3) Download the current firmware, unzip

Now disconnect from the internet and set your PC to a fixed IP (I used 192.168.1.220)
4) Connect the PC to the gigabit Port on the LAN set of the Draytek
5) Launch the Draytek tftp utility on the PC
5a- Browse to locate the .rst file from the unzipped firmware set
5b- Set the Host to 192.168.1.1
6) Turn off the Draytek - wait 10 seconds
7) Press in the Factory Reset Button and hold it in while turning on the Draytek
(once the lights start flashing, release the reset button)
8) Click on the Send button on the tftp Utility on the PC and clcik OK to confirm you want to upgrade
(do this quickly before the boot-loader times out)

Wait - it takes a while after the upload is complete before the Draytek reconfigures itself and reboots.

You're back in business
