It's possible to pack your own firmware images without any keys - the caveat is that flashing them will put your phone into open mode no matter what starting with the PR1.2 bootloader version.

The procedure is to:

• Unpack FIASCO image using flasher 3.5
• Unpack sparse image (rootfs.jffs2) using unlzo.py
• Mount rootfs image as an ext4 loopback device
• Do what you'd like
• Unmount rootfs
• Repack sparse image using sparsify.py
• Build FIASCO image from sparse image and layout file using fiasco-gen
• Flash FIASCO image to device using flasher 3.12.1

It isn't very easy to do, and most of those steps have to be done from a Linux system. Also, realistically, it isn't all that useful - though I released sparsify hoping that someone would do it anyway. :p If you really want to pack a custom image I'd help out with more info.

Edit: On second thought, one potential use would be for quick deployment of NITDroid, but IIRC e-yes wasn't too interested in this.

Thank you! By these steps I have successfully packed a firmware and flashed. With a little adjustment to the last step. The only problem is the warning picture when booting up, "disclaimer-cal remove View-openmode" won't work at all,I don't know how could I remove it.
