841N serial unbricking with... needles?!
There, I fixed it for you:
WARNING: this is a pro-only approach, as potentially bad contacts could introduce typing errors which could spoil your write address and brick the boot loader beyond recovery without you even noticing!
So after I got the ill router, I bought a new 3.3V CA-42 cable for about $3 at a local store. I didn't have my soldering kit nearby and anyway didn't want to mess up this beauty, so I first started experimenting. What could I lose besides a non-functional router? I have dozens of fully functional ones to spare. Actually, after all this messing around with firmwares, this is the only one of my routers which is bricked, and it wasn't even my fault.
Anyway, I first tested the vendor specific wiring of the cable. Blue is ground, white is RX and yellow is TX on mine. I've then proceeded with readout-only tests. Actually, touching the bare wires themselves almost worked. I could get an almost complete log this way. Although, to get the whole thing from beginning to end, I needed to push down on it a bit, otherwise periodically large sections were missing. However, touching by finger did introduce periodic bit errors, probably from the mains voltage.
I came up with a simple hack to thread the wires into sewing needles. The needles weigh themselves down nicely, but I added some extra weight and insulation, just in case. Bidirectional communication and recovery worked flawlessly on first attempt! Actually, a custom header with spring loaded pins with pyramid or cone shaped contacts on the end could be considered a decent solution in the long term. This is especially feasible if you have everything automated on the computer side and you would only need to keep contact for a few seconds. I already envision the vast unbricking pipelines!
Here's the (edited) serial log of the stuck error state until pressing the reset button. The previous owner may have interrupted power while upgrading. The SYS LED kept blinking after boot, wifi was working, however DHCP was not working on any interface, no ports found open and the device didn't even respond to ping, however tcpdump did show periodic broadcasts of router advertisements.
The instructions described in the serial TFTP recovery of the device worked well:
Here's a correct boot after recovering firmware 121101, because I couldn't find any older at the OEM. It's a good idea to keep the boot loader and the kernel in sync. I've then updated to 140724 via the web interface to enjoy free tftp unbricking.

Here's a correct boot after recovering firmware 121101, because I couldn't find any older at the OEM. It's a good idea to keep the boot loader and the kernel in sync. I've then updated to 140724 via the web interface to enjoy free tftp unbricking.
