Hi all... Thanks very much for the help. I'm still having problems - I get "no space left on device" errors and read errors. I'm not sure what the no space left errors are all about, df doesn't report any full disks:

# df
df
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 98412 0 98412 0% /dev
tmpfs 4096 4 4092 0% /sqlite_stmt_journals

Here's what I get when I try to load the recovery image. Note that I get basically the same thing from the 1.5.2 image now. I'm certain I've been spelling the names right, BTW, since when I misspell them I get a "no such file or directory" error. Any advice?

# cd /sdcard
cd /sdcard
# cat /dev/zero > /dev/mtd/mtd1
cat /dev/zero > /dev/mtd/mtd1
cat: write error: No space left on device
