Personally, I would reinstall all the original parts before continuing. I'm assuming that you aren't a Konica tech, due to your approach to this issue. For instance, having the SSD version number, and firmware level, would be relevant to this situation.
I will say... I dealt with a similar problem on a C364e last year. Machine stuck during boot, though it was at the "2 pillars" stage. Couldn't boot into service mode, so couldn't perform board backups/data transfer. SSD was at 6.01, but would code out (error 3320) when attempting to update. SSD tool did not work. Machine would not load MFP firmware (of any version). Tried removing all options, unplugging everything one by one, replacing DCPU, SSD, MFPB, and on and on and on. Everyone, including Konica, was stumped.
There is a long, long and twisted service history on this machine, enough to fill several posts. It was eventually recommended that I change the PWB-MCL board. However, this board is impossible to replace without having data backed up in service mode. Turns out, Konica has a magical device that is able to program a *new/unused* PWB-MCL with the relevant data to a particular Serial Number/Machine. There is (rumored) to be only one of these devices in North America and another in Japan. The North American team had to have the required files prepared by a team in Japan, then sent to the US, programmed into the new "donor" board, then shipped to me.
It didn't help.
The machine got scrapped the next month.
Thought it was an interesting story, though.
If you are interested, I can go through my notes/emails/SSD ticket related to this issue.
