Tried to update Stock Dockstar, now won't boot (1 reply)

Have a stock Dockstar. Had a very old U-Boot. Decide to update it before making any changes, no usb boot disk or anything.

Followed http://projects.doozan.com/uboot/ rebooted, worked.

Then followed Section A of http://forum.doozan.com/read.php?3,12381, also worked.

But then I try Section B. Did not work. I get:

## Booting kernel from Legacy Image at 00800000 ...
   Image Name:   Linux-2.6.22.18
   Created:      2010-10-19  23:05:02 UTC
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1979140 Bytes = 1.9 MiB
   Load Address: 00008000
   Entry Point:  00008000
   Verifying Checksum ... Bad Data CRC
ERROR: can't get kernel image!

I had saved the env at /root/current_envs.txt but I can't access it any more.

I am using a serial cable. So how can I fix this?
