I did upgrade directly from Merlin 378.55, but I don't see how that is supposed to change anything? Like I said, the initial upgrade itself went just fine and I was running 378.9135. It was the moment I hit factory restore within the webui everything went down the drain.
You don't have access to a serial TTL cable, by any chance?
My guess is, there's a default value that causes the router to crash at boot time once you are back to factory default reset. I've seen it happen a year or two ago with an RT-AC56U firmware. Try flashing an older firmware (my 378.55 would be fine for this test) through either the CFE Mini Web interface or Asus's Firmware Recovery tool.
Sadly I don't. I did try to recovery to 378.55, I also tried to revert back to the very first official RT-AC3200 firmware but there is no change to the behaviour. It sounds like you are correct as the router seems to be in a constant rebooting state, it seems to keep rebooting every five minutes or so.
So has anyone managed to install this new firmware AND perform a hard reset or use the factory defaults option?
That's the only time I get problems with this firmware, as soon as its reset (previous firmware works fine just this one playing up for me)
Yesterday, the Open Source for all the newly-released firmware on RT-AC68, RT-AC3200, and RT-AC87 was up on the website, which included this *.9135 version. Last night, I went to download and none of them were there any more. Is there something going on with this firmware? Without source, I'm a bit hesitant, especially with the apparent stability issues. If there's a problem, I *always* hit it. Anyone know why they pulled it from the site?
That often happens right after they upload a new file - it might take a few hours for all the servers in their cluster to be synchronized. Try again later.
How much later have you seen? I see I can get the source for .9135 on your github, but it's been 24 hours since I saw it, and more than 12 hours since I saw it was gone from the Asus site. If it comes back up, I'm curious whether it will be different in some way, that perhaps something was left out.
