You only need to flash stuff you do not already have installed. You can flash everything but main partition from fastboot. Once you have diags SSH access you can flash the main partition with dd.
First, you need to flash a diags partition that has SSH built in (and a matching diags kernel). Then you can start an SSH shell (where you can type linux commands into your kindle), by using the diags N-U-Z-X menu selections. You can use PuTTY in windows, or ssh in linux on the host PC after you have started an SSH session in diags. From there you can use the linux "dd" command to flash the large main partition. This can take a LONG time (several hours on some kindle models). Be sure to have a fully charged battery before doing this. This should already be in the "small debricking guide for noobs"
