Thanks, I have a green menu now.

No matter, I just wanted to view extra settings. "Also did you login to controller first for security?" - No, maybe I had to enter some code into Security Access?

I managed to update, I used SD Card, with USB it failed. But green menu does not activate, probably my cable is defective or weak.

I'll try a factory reset, then I'll try the engineering menu. I will write about the result.

I have a problem. I can't get to the green (engineering) menu. And when updating to MST2_EU_SK_ZR_P0253T, it gives me an error. Do you have any ideas?

Hy Guys i would like to have the latest Firmware Version to my Bolero . It‘s possible to get the Download link ?
