Update firmware on R710

[KDSM]

I have two (for now) R710 AP's that do not have a current version of firmware on them.  And when I connect them to the network to so that VSZ (5.2.2.0.317) can update to the current firmware I get the following error message.

" firmware version [3.2.1.0.642] is USI. USI to FSI upgrade is not allowed due to difference in Image formats."

Is there a way to correct this issue?   Can I flash the AP from the USB port on the back of the access point?

thanks.

You need to install an intermediate signed image (ISI).

Factory reset the AP then install a Solo 104 firmware (default user/pass is super/sp-admin).

The 104 firmware will join the 5.2 vSZ.

(You might also need to put a new cert on the AP).

Thanks for procedure:  When you do the factory reset on the AP does it install the firmware from an attached USB drive?

Nope. You need to install over the network.

The instructions here are good - just substitute in your Solo 104.0 firmware download whenever they mention Unleashed firmware.

Thanks.  i'll be trying this update today.
