ultimaker 2+ stuck on v3.3.0

[elnadav12 3]

Hi,

I got an ultimaker 2+ (um2 with upgrade kit) that is stuck for a couple of months on cura version 3.3.0

I tried to update it last month in cura version 3.4.0 but no success. same with 3.5.0/3.5.1

Is there any way i can fully flash the memory of the arduino board? idk what to do...

The UM2 firmware supplied with Cura 3.3, 3.4 and 3.5 are identical.

What isn't working with your UM2+? If it does power up, then execute a factory reset from the menu. This often resets problems with the internal configuration settings.

 

If the UM2+ doesn't power up, then the current Cura versions can't recognize the printer and uploading doesn't work. Is that what is happening?

Several other programs can help you out of this situation but I don't remember them all. One tool is the old Cura 15.04 version but there are others as well. Once the printer boots again you can use Cura 3.5 to install the most recent firmware.
