[benvanier]

Hello, i bought two used zf7372 that i am trying to joined to my zd1106.

i got this message on my zd: "Failed to upgrade AP[6c:aa:b3:0b:89:20] image from [10.1.2.0.120] to [9.10.2.0.130] after [16] retries"

I tried to downgrade the firmware using CLI using this firmware rcks_fw_zf7372_100_1_0_0_432.bl7

But i receive this error message: ←[Jrkscli: fw update

What would be the right path to do it?

You need to install an intermediate signed (ISI) firmware first, then you can downgrade to 9.10.

Solo 104 is ISI, so install this.
