How can i upgrade or downgrade to a version i want without cura?

I mean if i would like to try a downgrade or just try to reflash the actual firmware how can i do it?

First you need to locate various HEX files. The HEX files contain the Marlin firmware. You can build your own HEX file with marlin builder here which is a version from approximately 6 months ago:

You can install multiple versions of Cura and they each have their own version of Marlin although there weren't many (any?) changes from Jan 2013 to September 2013. When you install Cura there is a HEX file here (or similar):

C:\Program Files (x86)\Cura_12.12A\Cura\resources\firmware

You can install Marlin with any version of Cura in "expert" menu you can download any arbitrary HEX file to the machine.

Once installed you can check the version of Marlin using prontrface by simply connecting to it:

One more thing - you can get older versions of Cura here:

wow!

cool stuff!

do you think that the upgrade may have gone wrong and re-updating could cure the machine?

I'm still waiting the new plate and it's a month i'm not able to do anything..

i'm climbing a flat wall to understand why is like that.

And now i would like to try with the firmware..

Rome should have dozens of glass stores that can give you an identical glass plate for under 10 Euros in just a few hours.

The firmware upgrade process likely has checksums so that if the checksum doesn't match it doesn't run the new software. So it seems unlikely an upload could go bad.
