dd-wrt -> c9v1 bootloop #6

Open lee-soft opened 5 years ago

lee-soft commented 5 years ago

I can confirm that flashing the c9v1-webflash.bin from dd-wrt on my archer c9v1 results in a bootloop. TFTP recovery fails for all the images I tried to recover with (file is served successfully but the router continues it's bootloop after the file is served over TFTP). I tried to recover with dd-wrt archer c9v1 images, open-wrt, even the compiled firmware here, tplink official v9(UK) images.

Hi mate

I put the router in the drawer I forgot about it. I was going to order usb serial converter and repair it that way but hadn't got round to it yet. It was quite unstable on all ddwrt builds that I used before anyway. The WiFi was really choppy all the time. Most settings just made the WiFi really unstable. If you do stumble across a software fix please let me know.

I have a theory why this happened. I used a really old ddwrt build and I think it changed the way the nvram was being used. Perhaps this really upset the stock firmware? I think it expects it to be in a specific layout. Sorry it's all theory, not based on anything other than pure conjecture.

@lee-soft thanks for that update. I have it sitting under my bed now as well. It was indeed quite unstable on DD-WRT. I'm finally upgraded to proper Ubiquiti setup, about time I upgraded anyway.

hi eddie, i got round to flashing stock using the serial method which worked- then updating to the latest stock fw. router works flawlessly now. one minor alteration though, i had to power up the usb serial converter after powering up the router. 1. power up router, 2. power up converter, 3. open port, 4. send interrupt (ctrl-c)
