C258 won't boot / stuck at 2 bars

**Gift** · 12-27-2017

So my collegue tried the MFP board repair procedure. Booting the recovery tool -> no change -> booting with s-ata FW -> machine finally boot up into the update but says "FW already up to date". Then he did again installed the new eMMC board while leaving the HDD disconnected and then the machine worked. He was shure that he tried that before so it's unclear how this procedure did the magic. After re-installing the HDD the adress book was also back on track.

I'll keep the new MFP board in stock in case this is just a temporary success.

We've tried booting with MFP reset toll (that tiny 10kb *.tar file) - no change of behaviour unfortunately

Can I share firmware?

I had a C654 hang on 2 bars. I removed all accessories, finisher, ADF, all usb connections. See if it turns on. If it does, add one accessory at a time until you hang again. Or in my case just reseating the ADF pin connector fixed my issue.

Press "Stop" to boot A789be.tar No response, is there a problem (a789be.tar can also be used in 287?

Where does one find the reset tool on KM's tech side website? I can't seem to locate it anywhere? I've looked under special and regular firmware? Any guidance would be appreciated.

Thanks!
