Ok... restoring my C3000 to stock was quite the edjumacation. Having gone through that I think I could have solved my original problems just using the DB boot, fdisk, and mkfs. That's how I finally got the stock rom to boot, as it was just as unhappy as the 3kb1 rom.
That said, I finally have a stock machine localized to English (Thanks Trisoft!)
However, I'm back to attempting to get Cacko 3kb1 installed. I downloaded, after a lot of searching and frustration with Japanese character webpages, a file called zImage_v18a_c3000.bin in an attempt to install the Tetsu special kernel. However, every time I put this file (renamed as zImage.bin) on my CF and reflash the kernel, the system fails to boot. All I get is a slight "flashover" (i.e. LCD is birght, then dims) of the LCD and then it remains blank.
So... did I download the correct image?
Am I waiting long enough for the kernel to do it's work?
I'm so happy to have my Z booting again, but I really want the "chatty" boot mode of the Tetsu kernel back.
Its good to hear that you are back up and running. cacko for the c3k comes with kernel 17a (as per the release notes). if you want to upgrade the kernel to 18a (or 18b) you need to flash to cacko first, then install the kernel. if you installed the kernel first, cacko would overwrite it with 17a. you also need to rename it to simply zImage NOT zImage.bin. And you need to use the updater.sh from tetsu's site. (renamed to updater.sh). dont forget about installing the kernel modules for the kernel you choose (available as an IPK from tetsu's site). when back into qtopia issue a uname -a in the terminal to verify that all is well.
