Firmware Update Failure 477

[Yogi_LabM]

Hello,

I have updated 3 out of 4 printers on our network.

The last one is stuck with this message "A problem has occured with one of the printer's critical system files.  A printer update will be installed to fix this problem"

I can't do anything on the screen or trying to reflash the firmware.

Is there any solution available please ?

Thanks

Regards

I've searched a bit and finally i managed to make it work...

I've used an USB stick formatted with FAT32 and I've pasted 2 files on it (no idea which was the right one !)

HP_LaserJet_MPF_M477_M377_Series_FW_20190113.rfu

maverickdw_dist_pp1_001.1908C_nonassert_appsigned_lbi_rootfs_secure_signed.ful2

Once inserted, an upload message appeared automatically and it has updated the firmware

The printer is fully working right now 😄

On pagewide units likely the FUL file would be the correct one.

The .ful2 file is the correct firmware update file for this PageWide Pro device.  The .rfu file is for a LaserJet device (as the filename suggests), and it is also for use with Webjet Admin, not for use directly with the device via a usb flash drive.
