First up I'm really sorry about being so thick when it comes to this WDR7500 router. I'm in awe of what you're able to do hacking hardware for OpenWRT. I purchased the WDR7500 to put OpenWRT on, and learn.
The problem is that I've scoured the Internet, studied this thread and the OpenWRT wiki, loaded versions of tftpd onto a windows and a linux machine and tried to get a transfer going during the router boot sequence. None of this has worked. I simply don't know enough to get the combination or sequences correct. For example I've not witnessed the ttl change from 64 during boot.
I know there is lots of advice on this thread, and if I had more experience, I would be able to follow it and flash the router, but unfortunately, it hasn't worked and I have spent days in frustration not knowing what to do.
I'm wondering if someone who knows the exact process for flashing a chinese firmware WDR7500, to an English OpenWRT firmware could please give an up to date step by step dummies guide.
I've tried making tftpd work but nothing happens. What are the steps, what are the exact commands to issue?
Thank you sooo much
