When I performed the upgrade, it bricked my Linux - no WiFi, no Ethernet. I have been trying to recover using these instructions. But this depends on being able to establish communications via the Ethernet wired connection. This is the one thing I cannot confirm worked prior to upgrading (never had a need for it) so I am hoping there is some procedure I can follow to get it to work. I have tried:
patch cable to my router - WAN led blinks orange, router LED indicates connection, but no IP address is registered on the device table in my router (also tftp server cannot find it)
patch cable to PC - WAN LED blinks orange and the PC (Win7) indicates an "unknown connection", No internet (expected) but the tftp server still cannot connect. I tried setting the PC to 192.168.0.37 and the Yun to 192.168.0.64 as well as leaving the Yun at 192.168.1.2 and the PC at 192.168.1.3.
cross-over cable to PC - same result as patch
Also, in the terminal I see:
U-Boot 1.1.4-gd995931a-dirty (Aug 7 2013 - 16:16:04)

ATHRS26: s26 reset done

Does the "-dirty" label imply something is amiss? Is it recoverable?
Here is the log from one of my attempts. I should mention that I have successfully used the tftp server for other projects in the past so I am confident it is configured and running.

You did almost everything: you just skipped a step
setenv ipaddr 192.168.0.146;
TickTock:
patch cable to my router - WAN led blinks orange, router LED indicates connection, but no IP address is registered on the device table in my router (also tftp server cannot find it)
Indeed the router will NOT assign an IP, you have to input one: pick one that is not used by one of your home computers
TickTock:
Does the "-dirty" label imply something is amiss? Is it recoverable?
I did that deliberately for this particular log. I had done a printenv to learn that the ipaddr default address is 192.168.1.2 so I tried putting my PC on 192.168.1.3 for a peer2peer connection on this attempt. I have tried many different permutations trying to get it to connect (including setting the ipaddr to 192.168.0.64 and serverip to 192.168.0.41 using the router - my DHCP assigns to 192.168.0.x). I have not even been able to get a ping back from the Yun with any of the attempts although the router does indicate it has a connection on the front panel indicator and the WAN LED on the Yun sometimes blinks orange erratically like it is getting traffic.

[/quote]Like so many others, you are a bit thin on some of the networking info, considering that you mention both 192.168.1.x and 192.168.0.x IP addresses. Assuming a default /24 netmask (255.255.255.0 in dotted-decimal notation), those addresses don't mix.
If you are running Windows on your host PC, download and run "Angry IP Scanner" one the host PC's subnet (class C?) range. Maybe the IP address assigned to the Yun is not what you think it is...
Thanks for the suggestions. At this point I am open to any ideas but in particular I'd like to know if the uSD can be used by uboot. Sorry for the lack of details. I have tried dozens of scenarios and didn't want to clutter the post with minutia (it would have been pages long if I documented all my attempts). I think that was a good call since, even shortened, the point about the 192.168.1.x being a different experiment than the 192.168.0.x was overlooked. Yes, I am using 255.255.255.0. I have done this dozens of times with other devices so it's either some unique configuration requirement with the Yun or the ethernet driver is corrupt. I did, however, go ahead and try the AngryIP app but was unable to locate any "stray" responders.
I am new to uboot. I found a list of commands here and briefly got my hopes up that ext2load could be a means to use the uSD instead of tftp, but it appears those commands are not supported on this version of uboot. Anyone have any suggestions on how to do an update without ethernet (wired or wireless)?
TickTock:

No Internet Control Message Protocols (ICMP) support at Uboot.

If I understood correctly, you tried following a modified version of the instructions and that failed, right?
If so, can you now try to follow them exactly, without using commands that are not mentioned, step by step?
We struggle to make complicated things simple: make everyone happy by finding what's not working on that instructions or by making them even simpler.
OK. I went back and repeated the instructions exactly (even matching IPs this time). On the PC, I brought up Properties of the connection, went to TCP/IPv4 settings, selected "Used the following IP address", entered 192.168.0.231 and 255.255.255.0. Clicked OK. Opened a cmd prompt, typed IPCONFIG /ALL to confirm the IP was set. Then I reset the Yun and followed the instructions. Here is the Serial output:

In all my subsequent tests, I just tried the ping. If I cannot ping the Yun, tftp isn't going to work. I have also tried on a completely different (but also Win7) computer with the same results.
I guess I failed to mention that I connected a patch cord between the PC and the Yun (tried both patch and crossover - result is the same). The WAN light blinks and then goes steady orange after a minute or so but no communication. If I send another ping, the orange LED starts blinking again (but still see "host unreachable" on the PC).
Thanks. I use the tftp server by solarwinds and have been successful using that with other devices. I did order a 2nd Yun so I will confirm that it connects properly before submitting the RMA.
OK. New Yun arrived today. Plugged it in and tried the tftp procedure. Worked first try (see below) but I stopped short of committing it to the flash - learned my lesson. Going to request an RMA on the first and send it back. Key take-away : if it ain't broke, don't fix it.

Once you set the IP on your PC, were you still able to access internet? If not, there is a routing problem and that's why the yun cannot access the pc (and viceversa)
Never had any problems accessing the internet. Irrelevant, though, at this point now that I've proven that the Yun was the problem (if it was a router or other external problem, the new Yun wouldn't work either).
