Two mobile devices M65 do not update FW on M700

Dear community,

we here have an M700 with two M70, one M25 and the said two M65.

I managed to update the firmware on the M700 and M70+M25 to 530.02.

In the extensions section of the M700 management console, I saw that the binaries were also transmitted to the 2 M65.

Now, since yesterday afternoon, the status in the field "FWU progress". Both are placed in their charging cradles.

Has anyone experienced and solved such a situation or knows what to do anyways?

I appreciate aby help offered!

Regards, Andreas
