On the dd, the bs=4K just makes it run faster, but other than speed there is no difference. Where did you get the image you wrote to the main partition? Did you use SSH or a RUNME.sh script? Can you access the diags menus? Can you access your kindle as a USB drive? Can you talk to it with the fastboot program? What errors are reported in the startup logs?
Unless you have a hardware problem, one of the methods mentioned in the debricking threads has to work. We need more information to know exactly why you are having problems with your kindle.
I got image here http://gitbrew.org/~dasmoover/kindle/touch/forensic/
I used SSH, I can access diags menus, I can access Kindle as a USB device, I can talk to it with fastboot program.
I didn't understang how exactly can I get startup logs.
