Hi, today i had exactly the same problem as John Who after an update. i tried almost everything, lost many hours in front of the PC and DVR, and in my very last try (5 seconds before i look for a big hammer and destroy my DVR in more than 100 pieces) i find a solution. i just tested with different commandas and found one working, don't ask to my why, i'm not a linux expert, but it worked!

So i used this codes and worked:

setenv ipaddr 192.0.0.64
setenv serverip 192.0.0.128
setenv bootargs console=ttyS0,115200n8 root=/dev/ram0 rw initrd=0x42000000 init=/bin/sh
setenv bootcmd 'tftp 0x42000000 uImage; update'

Hope this can help to the next one with this problem.
THANK YOU SO MUCH!
i have 7b16-HUHI-K2 and bricked by upgrading to latest v3 firmware(india support provided me a 40mb file). no user to select and only 8 cams were showing in background, everything locked, no network access.

recovered using this tutorial but the commands like help or update didn't show up, only HKVS $ in serial.

attaching what i did for fellow users...
i upgraded to v4 latest firmware to date from this link, though i live in india the firmware works fine
