Follow the steps the in this guide to fix the firmware default for your phones, look at the very last section of the doc, you'll see a pic with "dual bank information". I know you did not install the device pack but it's the same concept.

I tried the same but still can't see the new firmware in device defaults.
I installed transit firmware then install the required firmware and it is done .
current load image : 12.0.1
transit image : 12.1.1
required image : 12.5.1
I am not sure this was the issue or not.
currently the next step is to apply the new image on phones.
so I have to reset all phones to do so . correct ? or phones should start upgrading themselves?
