Hello,
This version V6.5.0.1-HP560-B19720.cim.STARTUP is not for MSM430. This "HP560" within the name V6.5.0.1-HP560-B19720.cim.STARTUP means that this file is specifically for the AP model HP 560 ( for example HP 560 Wireless 802.11ac (WW) AP (J9846A) .
The corresponding file for MSM430 has the name V6.5.0.1-MSM430-MSM460-MSM466-MSM466R-B19720.cim.startup.
Also important to know that this is a .cim.startup file. This means that this file cannot be used to update the version of the AP via web GUI. It can be only installed on the AP via TFTP following the procedure described in this document. This procedure is only used if the AP cannot boot and no access to the GUI is possible.

I would suggest that you call your local support and request the correct .cim.startup version and install it on the AP following the procedure in the link.
