Smart-UPS 2200i firmware upgrade

[iqdata]

Hi, i have a Smart-UPS 2200 ( sku SMT2200I) with firmware revision UPS 09.3 (ID18).

Is it the last firmware ? I try to update with "smartups upgrade wizard 4.3.6" program, the updater report " the unit can be upgraded" but then no firmware option is given in the combo, and  the readme file  "smt18ups_15-0_readme.txt" tells 

Applicable Models:
Smart-UPS SMT UPSs (except 1U) rated 0.75, 1 & 1.5 kVA with ID 18

So, it seems is it no possible to upgrade firmware of this UPS model.

Is there a way to upgrade this model of smart ups ?

Thanks a lot
