Hilonc v2 upgrade error

Hi all,
i’m trying to upgrade HiloncV2 through host CPU, i follow SierraWireless(SW) guide and it work except for Customization step.

I already try with v8.00 and 7.40 with same result.

However upgrade process seems had done, but when i try to comunicate with Hilonc, it at power up sends:
+KSUP: 0
now if i send any AT command HiloncV2 answer correctly but after the first it hang up and it never answer to any other AT commands.

This is the end of upgrade log:
