Hello everyone
I have a challenge with a machine, which wont firmware upd.
When i insert the USB pen(The one i always use to firmware upd, have updated several hundreds if not thousands KM through my 17years in this business). Holding down the STOP key and power on the main switch. It DO shows the circle in the corner, but then it just starts up as normal. I have tried another usb pen, tried another firmware version. Tried to unmount the HDD and the finisher. Tried another USB port. Tried with front cover open, tried to clear all data, and tried to upd through Internet ISW @ FTP(This turns out with Download NG).
It is totally strange! I had a C258 some months ago, with the same issue, where i ended up replacing the MFP board.
But now it is the 2nd machine with this fault, and i suspect, something strange is blocking the firmware upd??
Do you have any suggestions??
