Draytek Vigor 2860n+ Firmware Update Gone Wrong

[BORIKKEN21]

Hi, I've been desperately trying to reset/upgrade the firmware on my Draytek vigor2860n+, all the network of the company I work for relies on it and 20+ VPNs now. I updated last night to the version 3.8.9.7, it was on 3.8.9.5. I did it using the web interface, somehow, when the router got rebooted it wasn't working anymore, it doesn't connect to the ethernet, only the DSL led stayed on and sometimes the 3 left ones start blinking, already tried to do a factory reset and update via Firmware Upgrade Utility v3.6.10, sometimes it goes well as it should, even says the router is active, but never works, pings or anything else. Their support staff just recommended to use the firmware upgrade utility, but I'm screwed until I can revive this one. We just use the ISP router to pass the ethernet to this one.

Any help would be so much appreciated, the healthcare institution I work is in a worry

Have you attempted resetting it and restoring the old firmware and settings?

[BORIKKEN21]

Yes I did! But the reset instruction never work like they state. the 3 lights never start to blink, just sometimes random without doing anything, also, wan port and lan 1 never light up, just the rest

Are you 100% sure you are using the right firmware for the device?
Are you also able to verify the SHA256 or at least MD5SUM of the firmware and check that what you have is matching what is listed on the Draytek firmware downloads section?
