CS820 Firmware issue

[jmr87]

Hi all, i've got an issue with a CS820 which was working absolutely perfectly before updating the firmware to the latest version. Previously it was on a 2016 version so very outdated.

The printer took the update via the web interface and rebooted and did all the usual stuff, but got stuck on a section saying something regarding MBR, it was on this overnight so had no option but to reboot it manually.

Now the printer boots, and all the touch interface works perfect, but it won't print, not even it's built in reports/forms - I eventually get an error saying service software engine failure or words to that effect.

The firmware version still shows in the web interface as the old 2016 version, and if I try to do the latest firmware again, it gets so far and errors with "invalid version". If I try to flash the firmware it currently has or ones just a few releases later, I get a "downgrade not possible" type error despite it not needing to downgrade.

It appears its in a mess, I've read online that you can use a Lenovo service restore tool but it needs a login.

If anyone can help i'm willing to pay a fee to anyone who can get me a file that will work!

Many thanks in advance
Jeff.

Tell me, from what version did you update and to what?

If you had an old firmware version, you should have updated through intermediate versions.

Downgrading is disabled in the latest firmware.

Show what version is written in the web interface.

Oh damn, I didn't see anything on the lexmark website re. the intermediate updates.

The version shown on the portal is YK.023.063.

I'm guessing I need a full restore firmware from the lexmark service tool .

You should contact Lexmark support so that they can send you all the required firmware and instructions.
