Re: C308 SSD Board Replacement / Availability
Just to update, after a lot of time in contact with KM's support center, they finally agreed with me that the eMMC board was the problem in this machine. They added a notation to the support request which allowed me to proceed with the order. The eMMC board has to be ordered through KM's warranty page, and can't be ordered directly through the regular parts/supplies ordering interface. You are also required to have an open call with the support center, as you have to enter the support request number into the form when requesting the part.
Our office has learned a few things through the process of troubleshooting this machine. Just to refresh memories, we had done a lot of parts swapping between the non-booting C308, and a working C308 we had in the office to try and narrow down the bad part. During this process things like eMMc boards and EEPROMS were swapped back and forth between the 2 machines. Neither machine was ever actually booted into the standard copier screens while the parts from the other were installed. All that was ever done was to boot into diagnostic mode (by holding down the power button), since we couldn't even do that on the dead machine. This was done in the hopes that data on the different eMMC and EEPROM chips wouldn't be cross-contaminated with information from the other machine.
In the end, it was determined that the eMMC board was the issue. The board was ordered and installed. Board replacement requires the firmware to be installed immediately after installation. Support confirmed that the boards come blank, with literally nothing on them. This makes me question why they must be be bought through KM for such a high price, but that's a story for another time. Firmware installed, typical reboot process, then error code, then recover data.
One unfortunate lesson learned here. Even when booting into just diagnostic mode, the system must still do some data verification checks and updates. Once the dead machine was back up and running, despite having it's original EEPROMs, the machine had inherited the serial number and meters from our good C308. Nothing had changed with the good C308, so I can only assume that the data stored on the good C308's eMMC board was pushed into some other storage area on the dead machine's MFPB. I conclude this because the EEPROMS from the dead machine were never installed at the same time as the good C308's eMMC board, so there was no way for the dead C308's EEPROMS to have been cross-contaminated with data from the good C308's eMMC board.
The serial number was updated to what it was supposed to be, but the meters are what the meters are, no way to change those. Live and learn I guess, and maybe this will help someone else out in the future.
