I think that only a "CFE over serial" (assuming that the router has an internal connection for it) would be able to recover from the failure - but I am not patient enough to go thru the pain...
Yep, that's also my fear...I did this once with a Linksys LAN to USB and I spend hours and days after setting up Linux, Python etc. but never a succes.
As far as I know, nobody has got JTAG to work on the ASUS ARM routers. You might be able to get in during the CFE boot process via the on board serial port (the pins are already there) and clear things up. Do a search for the AC56 and serial port....I seem to remember a set of directions being written up.Well the AC86U have JTAG
In my case (unfortunately) it does not: No reaction on WPS button (as said in the first posting already).This is getting more interesting. So for unknown reason a corrupted or incompatible nvram can cause recovery mode not to start.
Just a quick thought in such case does the firmware or cfe still honor wps button to erase and restore nvram? I would thin it needs lots of patience to recover...

I always end up with no reaction and fast flashing power LED!
But it looks like I am not the first one with a bricked device: As post by @mckeven in the posting above!
Looks like the JTAG approach works, but again, I am not patient enough to go that way...
Need to search now for new friend as Main Router...
I think JTAG doesn't work to load new code, but you may be able to get in to interrupt the CFE boot to be able issue some basic commands (like erasing nvram).I thought john said JTAG no worky on ARM.
Well, got this suggestion already above and answered here - it's not the problem as nobody was pressing WPS when it happened and the buttons work correctly.I would suggest you to take a look at your WPS Button, based on your description you have the button stucked, POWER LED fast blinking = WPS Button pressed (NVRAM Clean), its not the first router i see on this situation. (RESET and WPS buttons getting stuck)
Well, there is evidence that NVRAM can be messed-up during firmware update which will results in bricked routers (as outlined here for the AC68U and here for the AC56U). Only the JTAG approach will allow you to erase the NVRAM and bring the router back to life!You cannot brick a ASUS router with a FW flash, its highly unlikely, once the bootloader is there you will always bring it back to life.
I feel sorry for you, but it was Fork 380.57 HGG-FINAL which bricked the router (installed over Merlin's 380.57)...PS: You have bricked it from what FW? Tomato also? What was your bootloader version on the router?

Here's the thread I remembered about the 56U.....

Well, my AC68U was OCed since I have it, but never had this kind of problems until the last firmware update...joegreat, before you updated the firmware, did you reset your overclocked router to normal (no overclock)?
